HVAC and Indoor Air Quality

Many people believe that their HVAC system only delivers warm air in the winter and cool air in the summer and provides some ventilation. But the fact is your HVAC system has a great impact on the quality of air in your home all throughout the year. Our HVAC professionals at Hometown Heating, Air & Electric know that a well-maintained system can improve your home’s air quality, while a badly maintained one can worsen it.

Good HVAC, Good Air

Among the things a well-maintained HVAC system does for your indoor air quality are:

  • Remove pollutants and odors
  • Discourage pests
  • Keep humidity low
  • Keep home well ventilated

Our customers are often surprised to learn that the air inside their home can be many times more polluted than the air outdoors. But your HVAC system filters the outside air as it comes in, and that filter traps pollutants such as pollen, dust, mold spores, viruses and bacteria. The cleaner air that results lowers the risks of you or members of your household suffering from allergies, asthma or other respiratory problems.

One of the best things your air conditioning does is lower the humidity in your home, as cold air does not hold moisture as well as warm air. High humidity can make you comfortable even if the temperature is not very high. It can also encourage the growth of pathogenic mold and mildew. On the other hand, the cold air of winter is extremely dry, and the warmed air of a heating unit carries enough humidity to keep the household comfortable.

One problem with new homes is that they are well sealed to help them be more energy efficient. But a drawback of this is the interruption of a healthy airflow. Stale air holds on to pollutants and uncomfortable levels of humidity. Fortunately, the ventilation part of HVAC is the simplest to employ. Ceiling fans, the fans found in HVAC units and open doors and windows help the flow of fresh air throughout your home.

Bad HVAC, Bad Air

An HVAC system that is in disrepair not only fails to deliver cooling, heating and ventilation adequately but can actually be dangerous to your health. Simply, all of the problems that are prevented by a functioning HVAC system are present in one that is either badly maintained or that has been badly installed or designed. This means it allows bad smells and pollutants, including bacteria, mold and dust into the indoor air and blows warm or cool air at such speeds that you’re always uncomfortable. A bad HVAC system also does not regulate humidity, which leads to discomfort and can promote the growth of mold.

Leaking ductwork not only reduces the efficiency of your HVAC, but many critters, including possums, mice and rats find them the perfect places to build a nest. The ductwork blows their droppings and other waste into your indoor air. Worse, it’s not uncommon for animals to die in your ductwork, and the smell of that lingers even if your HVAC system is working.

But pollutants and procreating or dead animals aren’t even the worst things that can happen with leaky ductwork. Backdrafting can happen when gas from your boiler, furnace or hot water heater re-enters your home instead of being vented to the outside. This can cause carbon monoxide, an odorless, tasteless, colorless and deadly gas to infiltrate your rooms.

Bad smells from the ductwork are one sign of poor air quality caused by your HVAC. Other signs may be more subtle. The inside of your home may still be uncomfortably humid even with the AC on. One room may be much cooler or warmer than the other even though you don’t have a zoned system. The system may be blowing air at too high a speed, which also causes discomfort.

Don’t hesitate to call our HVAC professionals at Hometown Heating, Air & Electric to troubleshoot your system and make sure it and your indoor air quality are always in top condition.

When Should You Change Your HVAC Air Filter?

As air travels through your HVAC system, it’s forced through an air filter. This filter works to remove impurities from the air like pet dander and dust. To ensure that your air filter is consistently improving the quality of the air inside of your home, it’s important that it gets changed on a regular basis.

How to Tell That Your Air Filter Needs Changing

The best way to determine that it’s time to change your air filter is to take a look at its state. As a general rule of thumb, you should be able to hold a new filter up to a light and see through it. When your air filter has reached the end of its lifespan, it will be packed full of dust and other debris. When you hold the filter up to a light, you’ll no longer be able to see through it.

How Often Should You Visibly Inspect Your Air Filter?

If you’ve done any research online to see how often your HVAC air filter needs to be replaced, it’s likely that you’ve run across the recommendation of replacing it every three months. While this is a good general time frame for most households, it’s not a hard-and-fast rule. The specific conditions of your home, how often you run your HVAC system, and many other factors can affect how long your air filter will last. It’s typically recommended that you pull your air filter out once a month and check to see if it needs to be replaced.

Factors That Affect Filter Lifespan

The air filter inside of your HVAC system is a necessary component to ensure that the quality of your indoor air remains adequate. As soon as the filter starts to reach the end of its lifespan, it won’t be able to effectively filter out many of the harmful allergens that show up inside your indoor air. Households where family members have respiratory illnesses, asthma, allergies, and young children, should have their HVAC filters changed on a more consistent basis.

If you have multiple pets inside of your home, they’re constantly creating pet dander. This can make your air filter work much harder and greatly shorten its lifespan. Some other common factors that can influence the amount of time that the average filter will last in your HVAC system include smoking inside the home, how often you run your HVAC system, your typical household cleaning habits, and so much more.

How to Replace Your HVAC Air Filter

Changing out your HVAC air filter is something that you’re going to want to learn how to effectively do since it needs to be replaced on a consistent basis. Before you change out your filter, it’s a good idea to turn off your entire HVAC system. Next, you’ll want to access the filter housing. This may be located near the air handler or one of the wall vents, depending on the specific type of HVAC system that you have inside of your home. It’s a good idea to consult an HVAC professional or the instruction manual for your specific HVAC system to determine where the filter housing is.

Once you locate the filter housing, you’ll want to open it up and remove the old air filter. Go ahead and hold it up to a light source and see if it needs to be replaced. If so, you’ll want to have another filter on hand that is the exact same model number as the one that’s inside of your system. Make sure that you read the instructions that come with the new air filter to ensure that it’s being installed correctly. Many HVAC systems will have arrows that will help you to determine the appropriate direction to install the air filter so that it’s not installed backwards.

What Filter Replacement Should You Use?

When you go to purchase a new air filter for your HVAC system, you’ll need to have the existing filter’s model number so that you can purchase the same one. There are various different types of filters that you can purchase, including pleated, fiberglass, HEPA, and even reusable ones. Each of these different filters comes at its own price point and filtering capability.

It’s crucial to note that every HVAC air filter will have a MERV rating. MERV stands for minimum efficiency reporting value and is ranked on a scale from 1 to 16. The higher the MERV rank, the more efficient the air filter will be at trapping dust and other airborne particles. If you’re concerned about increasing the effectiveness of your HVAC air filter, you want to select one that has a higher MERV rating than your existing air filter.

How Long Can My Air Conditioner Run Continuously?

The humid Wisconsin summers mean that your air conditioner often has to work overtime to keep your home cool. As a result, we often get questions from customers asking if it’s okay for their air conditioning to run constantly. The answer is yes, it is fine if you leave your air conditioning constantly switched on. However, the condenser unit shouldn’t run constantly as this will quickly cause the motor to burn out. Moreover, if the condenser unit is running continuously, this indicates that your AC system isn’t working properly and needs to be repaired. To understand why, let’s take a look at cooling cycles to see how long the condenser unit should run under normal conditions.

Understanding Cooling Cycles

The condenser unit is the part of the air conditioning system that sits outside the home, and it serves two primary purposes. The first is to supply cold refrigerant liquid to the evaporator coil inside the indoor air handler unit, and the second is to release heat outside the home and compress the refrigerant back into a liquid.

As hot air passes over the evaporator coil, the refrigerant absorbs much of the heat from the air. This causes the refrigerant to heat up and turn from a liquid to a gas. The hot refrigerant then travels back out to the condenser where it flows through another series of coils to allow the heat to be released into the air outside. Finally, the condenser forces the cooled refrigerant through a compressor, which turns the refrigerant back into a liquid.

Your thermostat signals the condenser to turn on and start this cycle when the house gets warmer than the temperature the thermostat is set to. Once the condenser unit is on, it should run for approximately 15 to 20 minutes before switching off again. Typically, the condenser will perform two full cycles every hour or possibly three cycles in hotter or more humid conditions.

If the condenser runs more frequently than this, it usually indicates that the system is short-cycling. This essentially means that the condenser unit is shutting off before completing a full cycle. When this happens, the unit will typically attempt to start a new cycle immediately, which means the system will run almost constantly. Short cycling leads to increased energy use as well as greater wear and tear on the condenser. If not taken care of, the problem will usually cause the condenser to burn out and need to be replaced.

Common Causes of Short-Cycling

Numerous issues can cause a condenser to short-cycle. One of the most common causes is a clogged air filter, and this issue can be overcome simply by replacing the air filter. To prevent this, all you need to do is make sure to replace your filter at least once every one to three months.

Short-cycling can also occur if the condenser is either oversized or undersized. If the unit is too small, it will need to run almost constantly since it isn’t powerful enough to properly cool the home. If the unit is too big, the thermostat will typically signal it to turn off before completing a full cycle. In both cases, the problem will lead to higher energy bills and decreased home comfort. In these situations, your only real option is to replace the unit with one that is the appropriate size for your home.

Short cycling can also indicate that there is a leak in one of the refrigerant lines. If the system doesn’t have enough refrigerant, it won’t be able to properly absorb heat from inside the home and thus will need to run almost constantly. This issue can also cause either the evaporator coil in the air handler or the condenser coil in the condenser unit to freeze up. If you attempt to run your air conditioning while it is frozen, it will quickly cause the condenser motor to overheat and burn out. To prevent this, it is important that you not turn the AC on until you have a technician repair the leak and add more refrigerant into the system.

Will a Smart Thermostat Really Save Me Money?

If you’re like most homeowners, you’re always looking for ways to help cut down on energy bills when the summertime rolls around. One of the best ways to do this is to install a smart thermostat. These are not only super convenient to operate, but they can drastically reduce your energy bills.

It Learns Your Behaviors

Probably the most convenient feature of a smart thermostat is that after you program in your initial settings, it gets to learn your behavior. Over time, as it observes your behavior, it will be able to determine what temperature you prefer at various times of the day. Then, your smart thermostat can automatically adjust your settings to have your home at the perfect temperature whenever you get home and even calibrate it to make adjustments for specific humidity levels.

When your smart thermostat knows your behaviors, it can recommend the most energy-efficient settings without you having to lift a finger to try to program those settings yourself. You’ll be surprised at how much you can reduce your energy bills by simply changing your settings to more energy-efficient options.

Convenient Remote Interfaces

Another major benefit the smart thermostats bring to the table is convenient remote interfaces. Most smart thermostats will have an area on the interface that allows you to estimate the cost of the energy that you’re currently using. It will even allow you to make manual adjustments to your settings to see how they affect the cost of your energy bill. This can allow you to ultimately set the ideal temperatures for your home to meet what you want your energy budget to be.

Eco-Mode

All smart thermostats come with an eco-mode setting. This comes on whenever you’re away from your home and prevents your thermostat from running unless your indoor temperature reaches dangerously high or low levels. This is convenient as it will help to prevent emergencies like frozen water pipes whenever you’re away from home without you having to turn your entire HVAC system off. Many smart thermostats even automatically switch to eco-mode whenever it senses that there is no one in your home. It typically does this via tracking on your smartphone.

It Factors in Local Weather

One truly amazing attribute of smart thermostats is that they will actually take your local weather into account when it comes to optimizing your heating and cooling schedules. Using defined weather algorithms, smart thermostats can help to optimize energy usage and minimize humidity levels to ensure that your home feels comfortable for your family.

Remote Sensor Options

Fairly newer features that are coming out with many new smart thermostats are additional sensors. The sensors are designed to detect the temperature as well as motion. They’re to be installed in various rooms throughout your home to help your thermostat receive more precise information.

When it comes to temperature, your thermostat can learn what the general temperature is around your home as compared to just what the temperature is where the thermostat is positioned. This can be especially helpful in homes where thermostats aren’t optimally placed. The thermostat sensors also help to detect motion which is utilized to turn your HVAC system on and off depending on whether or not someone’s home.

User Simplicity

A very important way that smart thermostats can help you save money on your energy bills is their user-friendliness. Many programmable thermostats can offer an abundance of energy savings similar to that of smart thermostats. However, they require you to actually sit down and update your settings. Most homeowners simply don’t sit down and do so.

Smart thermostats take all the hard work out of programming your heating and cooling systems. With a couple of swipes of your smartphone, you can easily choose to program your smart thermostat to be the most energy efficient for your home. It’s super easy to make adjustments to help save energy usage from your smartphone as compared to having to go back to your thermostat every single time. Since smart thermostats are more convenient to use, homeowners actually implement smart choices to save energy, like lowering the temperature in the wintertime when they’re not at home.

Is It Smart to Save Money Buying a Used Furnace?

If you’re considering replacing your current furnace, you may have wondered if it’s OK to buy a used furnace to save some money. There’s a lot to weigh when comparing the option of buying a new furnace versus purchasing a used unit. You’ll need to consider things like price tags and different levels of efficiency. Buying used means you could end up with an energy hog or a highly efficient energy-saving machine; below are factors you can consider.

1. Check Its History

The first thing you need to do is investigate the furnace’s history. Make sure that it wasn’t recalled due to any safety issues in the past. Check its age and model number to make sure that there were no recalls or known problems with the unit. You can also ask the seller if they know any of its history and check with the manufacturer for more information.

2. Look for Signs of Water Damage

Water can cause serious damage to an older furnace and even lead to dangerous mold growth inside the unit. If the furnace is located in the basement — or another area that doesn’t get much air circulation — moisture and mold can be especially problematic. These conditions can cause corrosion, which can eventually lead to a leak or breakdown of the unit over time.

3. Examine the Heat Exchanger and Condensing Coils

The first thing to look for is a cracked heat exchanger. The heat exchanger is what keeps the exhaust fumes separate from the air that your family breathes. That’s why if there is a crack in the heat exchanger, it could possibly leak carbon monoxide into your home. If you suspect that has happened, you should not buy the furnace.

You also want to check the condensing coils. The condensing coils are very susceptible to damage from salt or other corrosives, which could be found in soils with high mineral content. You want to make sure they are not damaged or corroded when buying a used furnace.

4. Check for Wear, Tear, and Dirt on the Blower Motor

This is the most important part of a furnace. Check for signs of rust or corrosion on the blower fan. Rust is often a sign that water has entered the unit at some point in its life. This could mean it isn’t airtight and will allow moisture into the ducts when in use.

If you don’t see any rust, check for dirt on the fan or motor itself. If it’s dirty, this could indicate that it has been used heavily. You may need to remove insulation from the back of the furnace to get a good look at it.

Just how do you check for wear, tear, and dirt on the blower motor? You should be able to access this part of your furnace by opening up an access panel on its backside. If you can’t see it right away, try removing insulation from around it first — this may give you a better view of what’s going on inside your unit.

5. Consider the Age of a Used Furnace

If you are looking at purchasing a used furnace, then you will want to know the age of the furnace before making any final decisions. It is important to know the age of the furnace so that you will know how much life is left in it. You also need to consider how often or little the previous owner used it so that way you will be able to tell how much life is left in it as well.

A furnace can last anywhere from 10 to 25 years, depending on its brand and model. If the previous owner didn’t take good care of it, that could shorten the life span significantly. It could even cause safety issues if there are cracks or leaks in the system that could allow carbon monoxide gas into your home. This is why it’s so important to have an HVAC technician evaluate any used furnace before you buy it.

5. Check the Energy Efficiency

Furnaces are rated using the annual fuel utilization efficiency (AFUE). A higher AFUE means that more heat from the combustion process is transferred into your ductwork, which means less heat escapes through the flue. The higher the AFUE rating is, the more efficient your furnace will be.

When shopping for a used furnace, ask to see information on its AFUE rating. If you’re buying from an individual homeowner, they may not have this information available. In this case, ask how old their current furnace is and what year it was installed. From there, you can check average AFUE ratings by decade on the website of the company that made the furnace to get an idea of what their current system may be rated at.

How to Extend the Lifecycle of Your Cedarburg, WI Heating System

If your heating system has been working overtime for years to keep your Cedarburg, WI house warm and comfortable, it may be time to get it serviced. Although standard furnaces have a lifetime of 15 years, they frequently fail due to improper maintenance. Attention and regular maintenance, on the other hand, can make your furnace survive longer than its actual lifecycle. The following provides a few pointers to help you extend the lifecycle of your heating system and keep it in good working order.

Replace Your Air Filters

A clogged filter will make your furnace work harder. Dust, dirt, and other indoor contaminants are held in your filter, so they don’t recirculate through the air in your house. If you don’t replace that clogged-up filter, your system will have to work harder to pull air through it, potentially resulting in costly furnace repairs.

So, how frequently should you change your HVAC filter? The general rule is to change it every two to three months. However, if you have pets or household members with allergies, try changing your filter each month.

Have Your Ducts Cleaned

Your ductwork, like any other equipment, requires frequent cleaning and maintenance. Because air ducts are the medium that allows the heated air to enter your home, they are easily polluted with dirt, allergens, and other particles that degrade your air quality. Furthermore, unclean air ducts make your furnace operate harder than it should, thus reducing its lifespan.

As a result, to enhance your home’s air quality, arrange professional HVAC ductwork cleaning. If your home has allergic members, pets, or smokers, you should get your ductwork cleaned more frequently.

Upgrade Your Thermostat

The lifespan of your Cedarburg, WI furnace is determined by how hard you push it. If you’re at the office for eight hours daily but keep your furnace on full blast, you’ll be overworking your system and overpaying on your electricity bills.

Invest in a smart thermostat instead of needing to recall setting your thermostat before going out. You may program your thermostat to alter the temperature of your house depending on the time of day. Set your programmable thermostat’s temperature back by 7-10 degrees for eight hours each day to save the most money. This method can save you up to 10% on your heating expenditures.

Insulate Your Home

If your home has any openings through which heated air might escape, you must seal those gaps immediately. The loss of heated air would significantly increase your utility costs and make your heating system work harder to achieve your desired temperature.

Ensure that no heated air is escaping from the gaps in your ductwork, windows, doors, or any other house components. Maintain your home’s insulation and seal all leaks and cracks as soon as possible.

Use Fans Clockwise

Have you ever seen the tiny switch on the back of your ceiling fan? This is where you may change the rotation of the fan blades. Most people believe that ceiling fans are exclusively used to cool space. However, this is only true if the rotors are turned counter-clockwise. Change the direction of your ceiling fan to clockwise to help warm a space. This draws cold air up and forces any heated air from the ceiling downwards along your walls and onto the flooring.

Using this tactic will make your spaces warmer without requiring you to turn on your heating system. In fact, homeowners who utilize ceiling fans during winter can save 15% on heating costs. This also means that you’re not running your furnace until it’s necessary, which considerably extends its lifespan.

Perform Regular Maintenance

The best way of showing that you care about your furnace is by giving it seasonal maintenance. Get expert maintenance on your system every autumn before turning up your heating system. Allowing an HVAC expert to fully examine and clean your entire system on a regular basis may significantly increase the lifespan of your furnace. A clean furnace will not only operate more effectively than a filthy one but having a maintenance check will also allow our experts to notice any possible repair issues and solve them immediately before they cause significant harm to your system.

We are a certified, experienced, and licensed company serving Cedarburg, WI residents. Our experts can service or perform annual maintenance to keep your furnace working properly. We also offer furnace installation, cooling services, electrical installation, and indoor air quality service. Call Hometown Heating, Air & Electric today to set up an appointment.

What’s the Difference Between a Heat Pump and Furnace?

There’s a large draw toward heat pumps given their vastly superior efficiency rating. However, they may not be appropriate for every circumstance. Discover the differences between heat pumps and furnaces as you consider what’s best for your home.

Are There Similarities?

Before looking at what makes these systems different, let’s look at how they’re similar. Both still require air to flow through your house and the system. That means both will have air filters that need periodic changing. It also means that both will need routine maintenance to maintain their operational efficiency.

A professional should also size and install both. Getting a unit that’s too large or too small can have detrimental effects on the system, let alone your utility expenses. Further, both are hazardous to install if not done properly.

Furnaces Generate Heat

Furnaces generate heat to keep your house warm. Depending on your particular unit, it either does this with an electric resistance element or by burning a furnace fuel, which is more common. In southeastern Wisconsin, the most common fuel type is natural gas, which is run to individual homes through underground lines. In more rural areas or with older houses, there may be a fuel tank outside the house, which is usually either propane or oil.

Heat Pumps Transfer Heat

Heat pumps act more like an air conditioner in that their job is to transfer heat, not generate it. Just like an AC unit will absorb heat from the air inside of your home in the summer, making it cooler, it absorbs heat from the outside air in the winter.

This may seem a little odd since you probably think the air outside in the winter is cold. However, it’s cold because your skin and body temperature are warm. When the refrigerant in the heat pump system cycles to the coils outside, it expands and becomes very cold. This difference in temperature allows it to absorb heat, even from what you might think is cold.

When the refrigerant moves into the house, the compressor forces more refrigerant into a smaller space. This increases the pressure, which raises the temperature, allowing it to transfer the heat to the air inside of your home.

Since the heat pump isn’t actually producing heat, the air coming from your vents may not feel as warm as that from a furnace. Heat pumps tend to run nearly constantly in cold weather to keep your home comfortable.

Furnaces Are More Efficient in Colder Weather

Heat pumps can only transfer heat as long as the coils remain colder than the air temperature. The closer the air temperature gets to the temperature of the coils, the less efficiently it runs. The particular heat pump you have will determine the operational temperature range, with most models starting to lose efficiency around 40 degrees Fahrenheit and not working below 25 degrees.

This is why it’s recommended to have a secondary heat source for when the temperatures enter dangerously low ranges in Wisconsin. The most common is to have a furnace that will automatically kick in when temperatures drop below an efficient range. This ensures you’re always running the most efficient heating source for your home. Most all-electric models come with an electric resistance element heater. However, you may opt for a dual-fuel model, which has a standard gas or oil furnace as part of the package.

You Can Both Heat and Cool With a Heat Pump

One of the major draws for heat pumps is that they can pull double duty, both heating in the winter and cooling in the summer. These systems come equipped with a reversing valve, which changes the direction the refrigerant flows in the system. Over the summer, the inside part of the system is low pressure. However, it becomes high pressure during the winter.

Changing from heating to cooling mode is as simple as switching the setting on your thermostat. Simply hit a button or flip a switch, and the system knows what needs to change internally. Just be sure to adjust the temperature properly and reset your programs for the change of seasons.

Common Furnace Noises and What They Mean

When your furnace suddenly starts making strange sounds, it’s only natural to be concerned. You may be worried about spending a bunch of money on repairs, having your heating system break down on you, or even, in the worst-case scenarios, needing to replace your furnace altogether. Don’t panic yet, though. While many noises can represent problems and should not be taken lightly, the majority of them can be minimized if you’re proactive about it. Knowing what each type of noise means can help you save yourself quite a bit of discomfort and money.

Whistling Noise

A whistling noise is one of the least serious sounds you may hear coming from your heating system. The furnace’s air filter causes this noise in most cases. That air filter protects the furnace by trapping floating particles of dust and dirt, but when the filter itself becomes clogged, it makes it harder for the heating unit to pull air through. This is where the whistling noise is coming from, and you should take the sound as a signal that it’s time to replace the air filter with a new, clean one. Ideally, you should try to make this change a regular part of your furnace care routine.

Banging or Booming Noises

If you’re hearing occasional or even regular banging or booming noises coming from your furnace, you shouldn’t ignore it. These sounds typically happen with gas-burning furnaces, which usually means that gas is building up within the appliance. The noise happens when there is a delay with the ignition of the gas burners, which is usually caused by one of the burners being dirty or clogged. You won’t want to try and fix this yourself, and you also shouldn’t wait around to bring in a professional because a malfunctioning gas burner can sometimes cause damage to the heat exchanger, which is a more serious problem.

Screeching or Shrieking

If you’re hearing a high-pitched screeching, shrieking, or squealing sound coming from your furnace, it’s certainly annoying, but it’s probably not all that serious. In most cases, it’s caused by a motor issue such as a loose or damaged belt or possibly just a loose screw. It may also mean that the bearings need to be lubricated so that they can operate more smoothly. It will be hard to tell on your own which of these is actually causing it, so your best bet will be to bring in a heating technician as soon as you can.

Popping Noises

If you’re hearing occasional popping sounds coming from your HVAC system, the issue may actually be taking place in your air vents as opposed to inside your furnace. Your heating system uses these ducts to circulate heat throughout your household. However, sometimes when that warm air from the furnace comes in contact with the cold metal of the ducts, the metal starts to expand, which can result in those popping sounds that you’re hearing. In most cases, this is nothing to worry about, but for your own peace of mind, you may consider bringing in a ductwork expert for an inspection.

Rattling Noises

If your furnace is regularly making a rattling noise while it operates, you would be wise to turn the appliance off until you’re able to have it professionally inspected. It’s possible that this noise is only being caused by a loose panel or screw, which is a relatively minor concern. Alternatively, it could be a more serious problem, such as a cracked heat exchanger, which can lead to carbon monoxide leaking into your home. Even if the problem is only a loose screw, that loose part may end up contacting and damaging other parts of the furnace, so you don’t want to take the risk of leaving it running.

5 Tips to Ensure That Your HVAC System Is Ready for Winter Storms

Everyone knows how bad winters can be around Cedarburg, including the infamous snowstorms. One of the many challenges these intense storms bring is keeping your HVAC system running strongly. Here are five tips to prepare your HVAC system for the storms that are sure to come this winter.

1. Schedule Your Heating Maintenance

The most important thing that you can do at the start of the season to prepare for the coming storms is to get your system’s routine maintenance performed. You’ll enjoy better efficiency throughout the entire season as a result. However, you’ll also stave off predictable breakdowns when extreme weather strikes.

Routine maintenance cleans your system to allow it to operate with less stress, extending the life of all system components. Additionally, it seeks to identify components operating suboptimally before the weather turns frigid. Any components already straining will fail with the additional strain this weather brings, leaving your house without heat and with expensive emergency repair bills.

2. Check Your Vents

Your system depends on air movement to efficiently heat your home. It creates air movement by producing high pressure at the output vents and low pressure at the return vent. If these vents are closed or obstructed, then the air doesn’t circulate properly throughout your home.

This also means that closed doors inhibit your system’s ability to heat your home. Sure, one room may seem pleasantly warm, but it means that your system runs longer to bring the rest of your home to your set temperature.

Whenever possible, keep all doors open to spaces that your heating system serves. Keep your vents open, and ensure that each one has at least a 2-inch clearance above and around it. This ensures that air can effectively flow from the vent and create that circulatory flow.

3. Keep Your Air Filter Clean

Your air filter is critical to keeping air flowing through your HVAC system. It removes particles that would otherwise settle on the sensitive internal components. But its placement means it also easily creates an airflow restriction at the start of your system if it gets clogged.

Most 1-inch filters need replacing about every 90 days if you have average air quality. However, freezing temperatures may make your home unusually dry, leading to more airborne particles. Keep some extra filters on hand in case you need to change your filters during a storm.

Plan to check your filter monthly over the winter to catch it early when it clogs. When you do check it, gently vacuum off the intake side to extend the filter life and prevent reduced airflow through your system between filter changes.

4. Fix Small Problems

Small problems may be difficult to catch if they occur after your maintenance visit. However, noticing small changes may help prevent unnecessary strain on your system before the bitter cold arrives. Some subtle signs that you should watch for include:

  • Reduced airflow from your vents
  • Unusually long heating cycles
  • Cooler air from your vents
  • Unusual rattles or squeals
  • Sooty residue around your vents

A clogged air filter may cause some of these, so check there first. If you’ve just changed your filter, or if it’s pretty clean, call for a certified technician to identify the underlying problem. This protects your system and family from an emergency repair at the time you depend on your system to stay safe.

5. Think Through a Generator

Winter storms notoriously knock out power for at least a short time. Think about whether you’ll try to use a portable generator when this happens. Plan for where you’ll set up the generator so that you don’t risk carbon monoxide poisoning.

Plan for how you’ll which appliances you’ll connect to the generator and how you’ll get them connected. Be sure that you have appropriately sized and rated extension cords and know how you’ll run them through your home. Consider firing up the generator at the beginning of the season to make sure that it starts and runs properly before you might need it.

Prevent House Fires With These Space Heater Safety Tips

Sometimes there may be a room in your house that may not heat up as warm as you would like it. Installing a portable space heater can be a great way to help make that room warm up without having to increase the temperature for the entire house. If you’re thinking of putting a space heater in one of your rooms, you should follow these safety tips below to ensure that you don’t experience a house fire.

Be Home When It’s on

The most common reason that space heaters result in home fires is that the owners are not home when they’re running their space heaters. Your space heater should never be running if you’re not at home as you won’t be able to respond quickly if it has a problem. It’s also essential to note that you shouldn’t have your space heater running while you’re sleeping as you lack responsiveness during this time.

Give It at Least Three Feet

Due to the fact that space heaters let off a lot of heat, they can catch flammable objects on fire. It’s best to give your space heater three feet of open space the whole way around it. Be mindful of flammable objects like your curtains or your bookcase, as you don’t want them to be too close to your space heater. They could catch fire.

Go Directly to the Wall Outlet

Where you plug your space heater in will have a big impact on whether or not it’s safe. Space heaters draw a lot of energy which means they should be directly plugged into a wall outlet. And, you shouldn’t be using the outlet that is paired with it as you don’t want to draw too much energy from that circuit. Never plug your space heater into a power strip or an extension cord. This is due to the fact that many of these items cannot handle the amount of power that the space heater needs. They can easily get overloaded and end up causing a fire.

Ensure It Has a Safety Certification

Before you purchase your space heater, you should take the time to see if it has a safety certification on the box. There are three different types of safety certifications that can be given to a particular space heater, which are UL, CSA, and ETL. When the heater has this certification, it ensures you that it’s safe to use as it has passed rigorous testing.

Inspect It Often

Over time, natural wear and tear can deteriorate your space heater to the point where it needs to be replaced. You never want to run a space heater that has a cord with exposed wiring or housing that has started to crack. It’s best to do a quick check over of your entire space heater every time you go to plug it in to make sure that everything is in good condition.

Set Boundaries With Your Kids

Unlike adults, kids don’t always understand the dangers that come along with appliances. It’s highly advisable that you sit down and speak to your kids about boundaries regarding the space heater and the dangers that come along with it. Set restrictions for who is allowed to turn on the space heater and for how close your kids may get to the space heater.

Position It Low in Your Room

You want to avoid putting your space heater on all surfaces but the floor. It’s a bad idea to put a space heater on a coffee table, counter, cabinet, or even furniture for multiple reasons. The most important reason is that it’s more prone to being knocked over. When positioning your space heater, make sure that you don’t place it on the rug or carpeting that is prone to catching fire. Stick to hardwood or vinyl flooring.

Smoke Detectors

Before you opt for turning on your space heater, it’s a good idea to have smoke detectors installed throughout your home. You want to check these smoke detectors at least once a month and replace their batteries every six months. Most experts recommend placing a smoke detector outside the bedrooms in your home and as well as on each level of your home.
