Are you considering upgrading to a brand-new air conditioner or heat pump? If so, you’re about to make a significant investment in your family’s comfort and safety.

What is Proper HVAC Sizing?

Most homeowners might think that buying the latest and most expensive piece of HVAC technology is the best decision, but that isn’t always the case. Not many understand what it means to get a system that fits your home’s cooling needs.

Choosing the proper size is the process of selecting a unit with the proper level of cooling power for your home. This is not attained by estimation or guesswork. The process involves an evaluation of your home’s cooling needs to determine the power of the air conditioner needed to cool your home. This is important because if the AC is not the proper size, you will have to face different issues later on.

When an AC is Sized Wrongly

When an air conditioner is too small for a home, it will have difficulty reaching the level of cooling you need. When you set the thermostat to your preferred comfort level, the system will need to stay on longer, trying to reach it. In such a case, the compressor needs to work longer and harder, consuming more power, and shortening its lifespan. This issue will also result in your home having hot and cold spots, with warm areas in certain rooms where the cooling system is unable to overcome the heat sources such as large appliances and windows facing east or west.

Though you will be having different sets of problems with an oversized system, making such a decision will show its effects as soon as the system is installed. It will cool the house too quickly and turn off too soon. Your home will not have the benefit of gradual and even cooling. Dehumidification is another issue because the system won’t be running long enough to remove excess moisture in the air. As a result, expect to have a clammy and uncomfortable living space.

The real problem of installing an incorrectly sized air conditioner in your home is quite simple—you’ll have to buy another one much sooner than if you installed a properly sized one.

Benefits of Choosing the Right-Sized HVAC System

When you install a properly sized HVAC system, it will use far less energy to run and will cool your home satisfactorily. What this means is that you’ll get superb cooling power without having to spend too much on energy. You’ll appreciate the actual money savings, which you can use for other needs.

A correctly sized AC system can provide the right amount of cooled air into your home, allowing your family to stay comfortable even during the hottest days of summer. Now, this can be critical if you have family members who have respiratory issues. They can breathe much better and have greater comfort as the AC amply provides your home’s cooling needs.

If the system is working too hard to deliver cooled air, its components will begin to wear out sooner than expected. You’re going to have to repair those parts of the HVAC system, which can be very costly. That goes without mentioning the inconvenience of a breakdown can leave your family feeling uncomfortable. With annual maintenance on a properly sized system, you can avoid costly repairs and save money.
