3 Signs Your HVAC System Isn't Sized Correctly for Your Home June 10, 2020

3 Signs Your HVAC System Isn't Sized Correctly for Your Home, Mount Vernon, Ohio

Have you ever noticed uneven temperatures or extra humidity in your home? These problems are often due to the AC system; it may not be the right size or type for your needs. In many cases, the cooling unit is oversized. Here’s how to tell if this is an issue in your house. 

Is Your HVAC System Too Large?

1. Short AC Cycles

Once an AC unit turns on, it will work to reach the desired temperature on your thermostat. As soon as it does, it will automatically turn off. However, when your system is larger than necessary, it will quickly cool your home down, causing the AC to shut down. This is called short-cycling and puts stress on the unit, causing the parts to wear out and shortening the life span.

2. Mold & Allergies

acAC systems have vents that are tasked with emitting and absorbing air. However, an oversized unit will not run long enough to remove excess moisture in your home’s air. The result is higher than desired humidity levels in your home. Consequently, mold, mildew, and allergens can form in your home. Watch for musty smells, condensation on windows, respiratory issues, sneezing, and coughing.  All these things can indicate that your air conditioning system is causing a moisture problem in your home.

3. Uneven Temperatures & High Energy Bills

Since the AC will turn off too quickly when the system is oversized, rooms that are further away from the thermostat will get hotter than those closest to the interior. Additionally, short-cycling will increase your energy bills, as it will wear out the system and reduce efficiency. To check if this is a problem, see how much you paid last month to cool your home compared to the same time in the previous year.
