Air Conditioning Myths That Are Costing You Money and Energy

Air Conditioning Myths That Are Costing You Money and Energy

The history of air conditioning is a long and storied one. And, when a history is as deep and rich as this one, myths and stories are bound to pop up from time to time. Some myths seem plausible, while others seem utterly incomprehensible. Some of these myths are harmless, but some of them could cost you in the long run – literally. For the sake of the truth and your wallet, we wanted to put these myths to bed once and for all.

Myth 1: A fan is a great way to keep a room cool.

It’s true that a fan can make the room feel cooler, but the temperature won’t actually change. A fan works by aiding the body in transferring body heat into the air but, when no one is in the room, the fan is ineffectual. Leaving a fan on in an empty room will not keep the room cooler; it will only hike up your electric bill.

Myth 2: Cranking the AC will cool your home down faster.

Turning the thermostat down to 40 degrees won’t cool your home down any faster than if you set it to a comfy 70. The only thing that will happen when you set the thermostat ultra low is that your AC system will work longer trying to get the temperature to near freezing conditions.


Myth 3: Leaving your thermostat at a consistent temperature saves energy.

Some people believe that leaving your thermostat at a constant temperature all day is more efficient that letting your home warm up when you’re not around. To truly save energy and still live in comfort, your best bet is to use a programmable thermostat. Setting the temperature approximately 10 degrees warmer or colder (depending on the season) when you’re not home will give your HVAC system a much needed break, save energy, and still keep your home perfectly comfortable.

Myth 4: Closing vents will allow you to efficiently use your cooled air.

Closing the vents around your home might help control the temperature in a specific room, but it won’t help save energy. In fact, closing vents may hurt the performance of your HVAC system as a whole!

Myth 5: Air filters should be changed annually.

Air filters aren’t something that you change whenever you take down the Christmas tree. Ideally, they should be changed much more often (at least quarterly). New air filters not only improve air quality, but a new filter will improve the efficiency of your HVAC system.
