5 Common HVAC Myths, Busted

Whether you're looking at the coldest days of winter or the hottest days of summer, you want to get the most out of your HVAC system. Commerical HVAC providers want you to, as well. But there are some myths out there that HVAC service technicians wish you'd address, especially seeing as they're so common.

Here are five of the more common HVAC myths that HVAC companies have encountered in some form or another in the past:

Myth #1 - A Fan Is Like Your AC

Fans are designed to move the air throughout a room or space, but they're not designed to cool it like an air conditioner does. When that air that's being moved hits your skin, it cools you off even if the air isn't getting cooler. Despite popular belief, this does not make a room cooler. Only ACs can do that.

Myth #2 - Closing Your Vents Reduces Energy Bills

Believe it or not, this myth has even left commercial HVAC contractors scratching their heads. Many people think that when you're closing your vents you're reducing the amount of air being pushed throughout your home. But in reality, the pressure load will be balanced in the rooms of your home if the vent is open. If you block a vent you're making your system work harder because it's out of balance. That can actually raise costs.

Myth #3 - You Don't Have To Check Your Unit Unless Damaged

This is a big lie. You could contact Commercial HVAC providers for regular maintenance and service at least every few months. The filter alone on a unit needs to be changed at least once every three months. And regular checkups can dramatically lower the chance of problems occurring in the future.

Myth #4 - Cranking The Thermostat Will Work Quicker

This is false. Your system will work at the same power level to cool or warm the home no matter what temperature it is set at. Setting the thermostat a few degrees warmer or cooler than what you want won't speed things up.

Myth #5 - Short Bursts Will Keep Bills Low

Another falsehood! Your HVAC unit actually uses the most energy in the first 3-5 minutes of starting up. After that, it'll use less energy. If you turn it on and off, you'll actually waste more energy. Run it for 40-50 minutes at a time to get the best efficiency.
