HVAC systems are complex and somewhat mysterious to most homeowners. There are many myths that circulate about heating and cooling apparatuses, the benefits they provide, and how they can be used most efficiently. The primer below explains the truth behind four common misconceptions about these key household components. 

4 HVAC Myths Explained 

1. Ceiling Fans Keep Rooms Cool

Fans don’t impact temperature; they simply provide enhanced ventilation. They can, however, make you feel cooler by blowing past you. This is called the wind-chill effect. Although the atmospheric temperature will remain the same, you’ll feel more comfortable because your skin temperature will drop. The same phenomenon occurs outdoors. 

2. Closing Vents in Unused Rooms Improves Efficiency 

This concept seems intuitive, but unfortunately, shuttering one or two vents actually hampers efficiency. It will produce atmospheric pressure in the area where you’ve closed the outlet, which causes your system to pull in cold air through its return vent. With nowhere to travel, heated air will leak out or drift back towards your basement, wastefully dispersing to areas of your home where you don’t need it. 

3. The Location of Your Thermostat Doesn’t Matter

For your thermostat to work properly and get a correct reading, it needs to be mounted in a central part of your home. If it’s too close to windows, doors, vents, or radiators, it may think that it’s too hot or too cold in the entire home may adjust your HVAC system accordingly.

4. Bigger Is Better

This maxim isn’t necessarily true for HVAC systems. Choosing a size that matches your home’s needs will promote efficiency and cut down on costs. A unit that’s too small won’t get the job done, but one that’s too powerful or large will cycle on and off repeatedly to maintain the desired temperature. Since powering up or down uses significant energy, this will overtax your unit and increase your utility bills. Talk to your contractor about picking a capacity that suits your property.
