How to Select the Correct Size AC System for your Home

When it comes to the proper cooling of your home and optimal performance of your AC system, it’s critical that you select the appropriate sized AC unit for your home.

An over-sized or under-sized HVAC unit can result in higher energy bills, higher humidity levels and/or add more wear and tear on the compressor, blower fan motor and other components that can shorten your system’s lifespan.

Determining the Correct HVAC Unit Size

While there are some varying formulas out there on the web that can help you to roughly estimate the size of your HVAC system based on your home’s square footage, you’ll still need to have an HVAC professional to come to your home. An HVAC estimator will measure and assess your unique home’s requirements that help to determine the size and scope of your proposed HVAC system. This ensures that your new HVAC system is neither too large nor too small for your home.

Age of Your Home

Some older homes may have inadequate ventilation and/or ductwork to support the needs of a new system. Therefore, an HVAC professional needs to determine whether your home might need a retrofit to properly determine which HVAC unit will work best to promote optimal efficiency of your new system.

An older home may have an electrical system that needs to be brought up to code in order to accommodate a new system.

Consequences of an AC Unit that is Undersized

When your AC system is undersized (too small), it will be unable to adequately cool your home. This is evident when your AC unit running continually throughout the Summer days and your home never seems to be cool enough. This will lead to higher energy consumption and higher electric bills.

Consequences of an AC Unit that is Oversized

When you AC unit is too large for your home, it won’t run long enough to condense the air that accumulates on the coils. As a result, it won’t dehumidify the air effectively and thus, you will end up with more moisture. It will also start and stop more often throughout the day. This behavior will add wear and tear to your system resulting in more repairs and premature replacement.
