Whether you’re looking to buy a new HVAC unit or you want to replace your existing one, you need to take into account the size of your system. Fort Myers, FL residents know the importance of having a well-functioning HVAC system. Here are three ways that your unit’s size affects its ability to function properly:

Balanced Humidity

One of the major functions of HVAC systems is balancing the humidity of your home. This is very important during Florida’s humid summers. Units that aren’t properly sized will have difficulty managing humidity levels. In order for proper dehumidification to take place, the gathered water needs to be able to fully exit your home. Humidity first gathers on coils which then drips into a tray and then finally drains outside. If your unit isn’t sized correctly, this entire process may not take place or run too long, leading to imbalanced air moisture inside.

Proper Cycling

HVAC systems run in cycles. A properly sized HVAC unit will gradually heat or cool your home. If it’s too large, you’ll end up with cycles that run too rapidly and shut off quickly, oftentimes leading to uneven temperatures or incomplete humidity removal. Smaller systems will take longer to run, gradually heating or cooling your home and wasting energy.

Wear and Tear

If your HVAC system is undersized or oversized, then that will result in wear and tear. When your unit is always shutting on and off, it uses more energy than it can handle. Overworked HVAC systems mean more repairs. You’ll end up having to spend too much money on repairs when your system isn’t sized correctly. To avoid prematurely replacing your unit, you need to have your unit correctly sized by a professional HVAC technician.

Energy Cost

As we just mentioned, energy is a major component of getting your unit properly sized. Units that are too large or too small will use up more energy than one that’s sized correctly for your home. Even if the improperly sized unit has a great SEER rating, you’ll end up spending more on energy since the cycles are off and are therefore either running more frequently for a bigger unit or too long for a smaller one.
