Whether it’s freezing outside in January or hot enough to cook an egg in August, everyone is trying to get the most out of their HVAC unit. As your trusted HVAC experts, we know it’s our job to set the record straight for our loyal customers! We want you to know the truth behind the most common HVAC myths that we’ve heard throughout our career.

1. A fan will cool down a room

Fans are air circulators, designed and meant to move air around. Despite the air around you not getting any cooler, you get cooler from the air moving across your skin. Fun fact: Even if you leave a fan running in a room all day long, it won’t bring down the temperature of a room! Remember, it’s your AC’s job to cool down a room.

The reason why we recommend having a fan in your room to save money is that they can create the “illusion” of being cooled off! Basically, instead of turning your AC unit all the way down to 70 so that you can feel cooler, a fan may do the trick.

2. Closing off vents will reduce your energy bill

We’ve come across many people that think closing a vent can reduce the air being pushed through their home (and, in turn, reduce their bill). The reality, though, is that the pressure load should be balanced throughout your rooms (if you have a modern HVAC unit). If you decide to block a vent or two, you will most likely cause your HVAC system to be off-balance, eventually making it work harder! Remember: A unit working harder means your bill is getting larger.

3. You should call an HVAC tech only when you have a huge problem

You should schedule regular heating and air conditioning “checkups” with your local HVAC experts. The goal of regular checkups is to stop a small problem before it becomes a giant headache. Finding problems before they occur could save you from enormous bills and stress. Check out our maintenance programs to make the most of your HVAC system.

4. Cranking your thermostat all the way will cool or warm your home quicker

Your HVAC system will work at the same power level to cool or warm your home no matter what temperature you put it on. In addition, setting the thermostat a few degrees warmer or cooler than what you want won’t help to speed things up. Think about what temperature you’d like the room to be at and go with that number. Remember, a few degrees is all you need to completely change the feeling of your room.

5. Short operations of A/C will reduce your energy bill

Did you know that your HVAC unit uses most of its energy within the first three to five minutes of starting up? After starting up, it actually uses less energy. So if you are constantly turning your unit on and off, you’re actually wasting much more energy. Instead, let your unit run for 40-50 minutes at a time to get the best efficiency.
