Air conditioning units are an essential appliance in many households. With increased global temperature extremes, you need a system that can keep you comfortable throughout the year. There are two main types of air conditioning units available: ductless and central air conditioning units. Let’s take a closer look at each one.

Central Air Conditioning Units

Central air conditioning units are designed to cool an entire house or building through a system of ducts that distribute cool air throughout the space. They are typically more expensive to install than ductless units, but they are more efficient at cooling large spaces.

How Central Air Conditioning Units Work

Central air conditioning units work by pulling in warm air from the house through a return vent. The warm air is then cooled by the unit’s refrigerant and blown back into the house through the ducts. The cooled air is distributed evenly throughout the space, providing a comfortable temperature throughout the entire building.

Ductless Air Conditioning Units

Ductless air conditioning units are ideal for cooling specific areas or rooms in a house. These units are much easier to install than central air conditioning units because they don’t require ductwork. Ductless units consist of an outdoor compressor and an indoor unit that is mounted on a wall or ceiling. They are also more energy-efficient than central air conditioning units because they don’t experience the energy loss that occurs in ductwork.

How Ductless Air Conditioning Units Work

Ductless air conditioning units work by pulling in warm air from the room through the indoor unit. The warm air is then cooled by the unit’s refrigerant and blown back into the room through the same unit. Ductless units are designed to cool specific areas or rooms and are ideal for homes with multiple floors or rooms that are infrequently used.

Major Differences Between Ductless and Central Air Conditioning Units

The two types of air conditioning units differ in terms of installation, flexibility, efficiency, and maintenance requirements.

Installation

One of the biggest differences between ductless and central AC units is the installation process. Central air conditioning requires ductwork to be installed throughout the building, which can be a time-consuming and expensive process. Ductless units, on the other hand, require only a small hole to be drilled in the wall for the refrigerant lines to pass through, making them much easier and less expensive to install.

Flexibility

Ductless air conditioning units are designed to cool specific areas or rooms in a building, while central air conditioning is designed to cool the entire building. This means that ductless units offer more flexibility in terms of zoning and temperature control. With a ductless unit, you can set different temperatures in different rooms, which can be more energy-efficient and cost-effective.

Efficiency

Ductless air conditioning units have an advantage over central AC units. This is because ductless air conditioning requires little ductwork, which reduces energy loss through leaks and poor insulation. In contrast, central air conditioning units usually incorporate a lengthy ductwork, which may reduce efficiency. However, the efficiency of central AC units can be improved through regular maintenance of the ductwork, such as cleaning and sealing any leaks.

Maintenance

Maintenance requirements for ductless and central AC units are also different. Central air conditioning requires regular maintenance of the ductwork to ensure that it’s clean and free from leaks. For ductless units, you will need to clean filters and coils to ensure that they’re working efficiently.

Which One to Choose?

The choice between ductless and central air conditioning units largely depends on your cooling needs and budget. If you need to cool an entire house or building, then a central air conditioning unit would be the best option. However, if you need to cool specific areas or rooms, then a ductless air conditioning unit would be the ideal choice.

There are many options to choose from when you’re faced with installing a new air conditioning unit. Among them, you’ll need to decide the level of efficiency you want, which gets into the technology used in the unit. Higher-efficiency models use what’s known as variable-capacity technology. Use this guide to understand how standard ACs work, how variable-capacity systems work differently, and the differences you’ll experience when you install one in your home.

How Standard Air Conditioners Work

Standard air conditioners are known as single-stage units. This means that the entire unit is either on or off, with no settings for lower-capacity cooling. The result is that your system runs on high all the time, keeping the cooling cycle relatively short.

The step between the single-stage and variable-capacity system is a two-stage system. These provide a second option, offering a high and low setting for your system. However, many homes need a little more fine-tuning to get the right cooling capacity to keep the home ideally comfortable throughout the summer.

What Variable-Capacity Central ACs Do Differently

A variable-capacity AC has both a variable-capacity compressor and a variable-speed fan. With a variable-capacity system, your compressor may have as many as 700 distinct settings available to use. This allows the system to dial into the exact cooling capacity your home needs at any given time.

A variable-capacity air conditioner will generally run nearly continuously, providing a steady stream of air moving around your home. Even with it running steadily, it consumes less energy because the compressor isn’t consuming as much energy to keep your home cool.

More Consistent Home Comfort

A single-stage air conditioner drops the temperature, then waits for it to rise to start a new cooling cycle, whereby it drops the temperature again. The reason a variable capacity runs constantly is to keep your home at a constant temperature. By keeping a steady stream of cooler air moving around your home, the temperature stays more consistent all the time.

Better Cooling Efficiency

Cooling efficiency is rated using SEER, or seasonal energy efficiency ratio. This is a comparison of the total cooling output for the entire summer divided by the total energy used. The energy output drops when you reduce the cooling capacity at which the system runs. However, the energy consumption drops more than the cooling capacity. This is how high-efficiency systems get an efficiency rating of 25 SEER and higher.

Better Home Comfort

Your air conditioner does so much more than just reduce the temperature of your home. It removes airborne contaminants, condenses humidity from the air, and keeps air moving around your home. A single-stage air conditioner runs average cooling cycles of 10 to 15 minutes. That leaves a lot of time where it’s not moving air or removing humidity. By running more constantly but at a lower capacity, your system will remove more contaminants and humidity and keep the air continually moving around your home, creating a more comfortable environment.

Less Noisy Operation

One of the complaints about air conditioners is the amount of noise they create. With single-stage systems, a lot of this noise happens because the system is running on high all the time. When you reduce how fast a fan spins, you reduce some of its noise, and the same is true for the compressor. A variable-capacity system will run at some iteration of a lower capacity 80% of the time it runs, significantly reducing its noise.

Longer Service Life

The average single-stage air conditioner will have a service life of 10 to 15 years when it receives proper maintenance. Much of the wear on the system comes from running at full capacity all the time and frequently starting new cooling cycles, which is the most strenuous part of the cycle. A variable-capacity air conditioner runs as low as 40% of its maximum capacity and runs nearly constantly, which significantly reduces the wear on the system. Further, with a variable-capacity system, you’re already at the higher range of efficiency, which means the increasing standards will take longer to make your system’s efficiency obsolete.

From preventative maintenance checks to tweaking settings on your thermostat, there are plenty of steps you can take right now that will have great results in comfort and energy savings this summer. Here are seven tips to help you get your cooling system ready for summer.

1. Clean and Change Filters

When filters become clogged or dirty, it can affect air circulation and cause breakdowns or necessitate repairs. To prevent these inconvenient and expensive outcomes, set aside time to properly maintain your cooling system by cleaning any dust that’s built up on fans and coils as well as changing air filters. This small investment in regular maintenance can mean significant financial and comfort gains throughout the year. HVAC experts like those at [company_name] can help you get your filters cleaned or replaced.

2. Check Refrigerant Levels

Refrigerant is an essential component of air conditioning systems, as it aids cooling by absorbing the required heat. Low refrigerant levels in your cooling system can reduce its efficiency and cause damage over time. Checking your system’s refrigerant levels will ensure that all components function correctly. Further, it can help to prevent potential damage or malfunctions in the long run. To ensure that your refrigerant levels are where they should be, get them checked by a professional technician before each season begins.

3. Inspect Electrical Connections

Ensure all the electrical connections on your cooling system are tight and secure, as loose connections can lead to overheating, which can cause severe damage to the unit. Keeping essential parts such as compressors, fans, and motors in good working order increases your unit’s efficiency and extends its serviceable life. Checking for loose or corroded cables and terminals will ensure that all necessary current is securely making it to each component. If any issues are identified, have HVAC technicians address them before turning on the unit.

4. Schedule HVAC Maintenance

Scheduling regular HVAC maintenance can reduce the chances of costly repairs and keep your cooling system running smoothly. Maintenance visits are a great way to ensure your AC unit is functioning correctly. It an also help you catch an issue before it causes any service disruption or escalates repair costs. In addition, routine maintenance allows for timely checkups that can identify energy-consuming issues, reducing energy bills from month to month. Don’t wait until something goes wrong. Instead, book a periodic maintenance checkup with [company_name] to ensure your cooling system weathers against the seasonal elements without any unnecessary stress.

5. Check Ductwork

Ductwork should also be inspected regularly for any obstructions, such as dust buildup or mold growth, that could impede airflow throughout your home when running an AC unit. Check for visible insulation damage, and then make sure there are no blockages that could reduce airflow efficiency. The cooled air can be lost instead of circulated throughout the house if your ducts aren’t properly sealed. Other problems that should be addressed include cracks, disconnected parts, and weak insulation. A professional technician can identify if there’s an issue with ductwork and advise solutions accordingly.

6. Inspect Insulation Around Outdoor Components

Inspecting insulation around outdoor components helps keep excess heat away from more sensitive parts like condenser coils, improving overall efficiency when running an AC unit during the warmer months. This includes ensuring adequate insulation between indoor walls and exterior components and checking seals on windows near outdoor units for gaps or drafts that could let unwanted heat into interior spaces.

7. Check the Condensate Drains and Coils

Condensate drains remove moisture that builds up in an air conditioner, while coils transfer heat between two mediums in a heating and cooling system. To prepare your cooling system for seasonal changes, regularly check the condensate drains and coils. This will help prevent clogs and ensure the system runs safely and efficiently. Condensate should be checked for dirt, blockages, and insect infestations. Coils should be vacuumed out of dust and debris buildup while testing electrical connections to see if they’re functioning correctly.
