Common Myths About Your Air Conditioner

Two workers on the roof of a building working on the air conditioning unit.

Here are some of the most common air conditioning myths paired with the facts you need to know.

Myth: Using an air conditioner will give you a cold.
Reality: Completely untrue, according to the AARP. While becoming chilled may make you more vulnerable to illness, the common cold is caused by a virus, not the temperature.

Myth: It’s a waste of time and money to have your air conditioner serviced.
Reality: False. AC units need to breathe. Regular cleaning can keep your unit running smoothly and efficiently. It also provides an opportunity to catch problems that might have developed over the winter.

Myth: You can save money by turning the AC off or setting the thermostat extra high when you leave the house, then turning the thermostat down when you come home.
Reality: Untrue on both counts. When you come home to a hot house, the air conditioner has to work much harder to cool the place down.

Myth: It’s cheaper to leave the thermostat at the same temperature all day, even when you go to work.
Reality: Not true. Using a programmable thermostat can let the house warm up while you’re gone, then start cooling things down before you get home.

Myth: The air conditioner won’t run as much if you keep ceiling fans turned on.
Reality: Totally false. Fans don’t cool air; they just move it around.
