3 A/C Myths Costing You Money (And What To Do About It)

With the summer season cranking up the heat, we want to help keep your home as cool as possible. Unfortunately, much of the advice you hear may not be true, so let’s bust a few common HVAC myths to keep from falling victim to them! 

MYTH 1: It’s cheaper to set the thermostat extra high when leaving the house

You may think you’re saving your air conditioner work by turning it off for the day. But when you get home and flip it back on? Your air conditioner has to work that much harder to cool the whole place back down. Instead, opt to let the house warm up a few degrees while you’re gone, turning the temperature back down when you get back home. This allows your system to take a break when it doesn’t need to use energy.

MYTH 2: Turning the thermostat way down helps the A/C cool things faster

Your air conditioner usually works at one speed. Setting a room at a significantly lower temperature in an attempt to cool the space quickly will just mean the system will be working at one speed for longer. We’d just recommend setting your thermostat to the desired temperature and letting the A/C do its thing!

MYTH 3: The air conditioner won’t run as much if you keep ceiling fans turned on.

Believe it or not, ceiling fans don’t actually create cool air! They just move the air around that’s already in the room. The best tip here would be to use your ceiling fans when you’re spending time in that room, but turn them off to save electricity when you leave.


Out of all these myths, here’s the BIG TRUTH — using your air conditioner sensibly is the best way to save you money on cooling your home. And keeping your unit in tip-top shape is a great place to start!
