When summer temperatures rise in Wisconsin, so can your monthly energy bills. Your air conditioner may run for hours each day to keep your home comfortable, especially during long stretches of hot and humid weather.
Fortunately, lowering your energy bills does not have to mean turning off the air conditioning or living in an uncomfortable home. A few practical changes can reduce energy use, help your cooling system operate more efficiently, and keep your family comfortable throughout the summer.
From adjusting your thermostat to improving insulation, these summer energy saving tips can help you get more from your HVAC system without sacrificing comfort.
Adjust Your Thermostat Strategically
Your thermostat has a significant effect on both your comfort and your energy usage. Setting it extremely low will not cool your home faster. Instead, it can cause your air conditioner to run longer and use more electricity.
Choose the highest temperature that still feels comfortable for your household. Raising the thermostat by even a few degrees while you are away from home can help reduce unnecessary cooling costs.
A programmable or smart thermostat can make these adjustments easier. You can create a schedule that raises the temperature while the house is empty and lowers it before you return. This allows you to save energy without coming home to an uncomfortable space.
Avoid making frequent, dramatic temperature changes. A consistent schedule generally helps your HVAC system operate more efficiently than repeatedly raising and lowering the thermostat.
Change Your Air Filter Regularly
One of the simplest ways to improve HVAC efficiency is to keep your air filter clean.
A clogged filter restricts airflow and forces your system to work harder to move cooled air throughout your home. This increased workload can raise energy consumption, reduce comfort, and contribute to unnecessary wear on your equipment.
Check your filter every month during the summer, especially if you have pets, allergies, ongoing home improvement projects, or higher levels of dust. Replacement frequency depends on the type of filter and the conditions inside your home, but many filters should be changed every one to three months.
Using the correct filter is also important. A filter that is too restrictive for your system can reduce airflow, even when it is clean. A qualified HVAC technician can help you choose the right option for your equipment and your household’s needs.
For homeowners concerned about dust, allergens, or humidity, professional indoor air quality solutions may help improve both comfort and air quality.
Schedule Professional HVAC Maintenance
Routine maintenance is one of the most effective ways to reduce air conditioning costs and prevent unexpected breakdowns.
During a professional air conditioning maintenance appointment, a technician can inspect the system, clean important components, test performance, and look for problems that may be affecting efficiency.
Maintenance may include:
- Cleaning condenser coils
- Inspecting electrical connections
- Checking refrigerant levels
- Testing the thermostat
- Examining the blower motor
- Checking airflow
- Inspecting the condensate drain
- Identifying worn or damaged components
Small problems can cause your air conditioner to run longer than necessary. Addressing them early can improve performance and reduce the risk of a breakdown during the hottest days of summer.
If your system is making unusual noises, producing weak airflow, short cycling, or failing to maintain a comfortable temperature, it may be time to schedule air conditioning repair services.
Keep Cool Air Inside Your Home
Your air conditioner can run efficiently and still struggle if cooled air is escaping from your home.
Gaps around windows, doors, attic access points, and utility openings allow cool indoor air to escape while warm outdoor air enters. Poor insulation can also make it difficult to maintain a consistent indoor temperature, particularly in upper levels and rooms exposed to direct sunlight.
Consider checking the following areas:
- Weatherstripping around exterior doors
- Caulking around windows
- Attic insulation
- Basement and crawl space air leaks
- Recessed lighting openings
- Ductwork located in unconditioned spaces
Sealing air leaks and improving insulation can help your home retain cooled air longer. This reduces the amount of time your air conditioner needs to run and can make temperatures feel more consistent from room to room.
Closing blinds or curtains during the hottest part of the day can also reduce solar heat entering through the windows.
Use Ceiling Fans to Improve Comfort
Ceiling fans can help you feel cooler without requiring you to lower the thermostat.
Fans do not reduce the actual temperature of a room. Instead, they circulate air across your skin, creating a cooling effect. This may allow you to raise the thermostat slightly while remaining comfortable.
During the summer, most ceiling fans should rotate counterclockwise when viewed from below. This pushes air downward into the room.
Remember to turn fans off when no one is in the room. Since fans cool people rather than the air itself, leaving them running in an empty space wastes electricity.
Portable fans can also improve circulation in areas that feel warmer than the rest of the house. However, persistent hot or cold spots may indicate an airflow, insulation, or ductwork issue that should be evaluated by a professional.
Keep Supply Vents Open and Unobstructed
Furniture, rugs, curtains, and other household items can block supply or return vents. When airflow is restricted, your HVAC system may have difficulty distributing cooled air throughout the home.
Check each room to make sure vents are open and free from obstructions. Vacuuming dust and debris from vent covers can also help maintain proper airflow.
Although closing vents in unused rooms may seem like a way to save energy, it can create pressure imbalances in certain HVAC systems. This may reduce efficiency and place additional strain on the equipment.
A professional can help determine whether zoning, duct adjustments, or other improvements would be a better solution for controlling temperatures in different areas of the home.
Reduce Heat-Producing Activities
Everyday household activities can add heat to your home and cause your air conditioner to work harder.
During especially hot weather, consider using ovens, clothes dryers, and dishwashers during the cooler morning or evening hours. Grilling outdoors or preparing meals that require less cooking can also reduce indoor heat.
Turn off lights and electronics when they are not being used. Many appliances and devices generate heat, even when their energy consumption seems relatively small.
Using bathroom and kitchen exhaust fans can help remove heat and moisture, but avoid leaving them on longer than necessary because they can also pull cooled air out of the home.
Improve Overall HVAC Efficiency
An air conditioner that is properly sized and maintained should provide reliable cooling without excessive energy use. However, older or inefficient equipment may struggle to keep up during hot weather.
Signs of reduced HVAC efficiency may include:
- Rising energy bills without a clear explanation
- Frequent repairs
- Uneven temperatures
- Excessive indoor humidity
- Long cooling cycles
- An air conditioner that runs almost constantly
- Equipment that is more than 10 to 15 years old
Repair may be the right choice when a problem is minor and the system is otherwise dependable. However, if the equipment is older, inefficient, or requires repeated repairs, investing in air conditioning installation may provide more reliable comfort and lower operating costs.
A new system should be properly sized for the home. Bigger is not always better. Oversized equipment may turn on and off too frequently, while undersized equipment may run constantly and still fail to maintain the desired temperature.
Professional load calculations can help determine the appropriate system size for your home.
Do Not Ignore Indoor Humidity
Wisconsin summers can be humid, and humidity has a major influence on how comfortable your home feels.
When indoor air contains too much moisture, the home may feel warmer and stickier even when the thermostat shows a reasonable temperature. This can tempt homeowners to lower the thermostat and use more energy.
A properly operating air conditioner should remove some humidity as it cools. If your home remains humid, the system may need maintenance, adjustment, or additional humidity control.
Improving humidity levels can make your home feel more comfortable without requiring a lower thermostat setting.
Stay Comfortable and Save Energy This Summer
You do not have to choose between a comfortable home and manageable energy bills. Strategic thermostat settings, clean air filters, routine maintenance, proper insulation, ceiling fans, and an efficient HVAC system can all help reduce summer cooling costs.
Pay attention to changes in your system’s performance and energy usage. A sudden increase in utility bills, weak airflow, uneven temperatures, or excessive humidity may indicate that your air conditioner needs professional attention.
