Making assumptions about your air conditioning system can cost you cold, hard cash.

Don’t end up spending money you don’t have to because you fell for an air conditioning myth you heard or read somewhere. Here are four things people may assume are true about their air conditioning. Get ready to bust these myths and save some money over the summer.

Myth No. 1: Ceiling fans keep rooms cool

Why it’s a myth: Ceiling fans have no real effect on the temperature of a room. People often think ceiling fans cool rooms because they feel cooler when the fans are on.

What makes people believe this is that the air moving across their skin makes them feel cooler. This does not mean the room is cooling.

Because a ceiling fan doesn’t actually cool a room, you can turn off the fan when you leave the room and save on your electric bill.

Myth No. 2: Air conditioning units perform the same no matter where they are installed

Why it’s a myth: The location of the unit can have an effect on its performance. Place the unit away from direct sunlight. The best locations, in general, are on the north or east side of your house.

Myth No. 3: Unless something is wrong, you don’t need to inspect your air conditioning system

Why it’s a myth: Preventative maintenance is always the best way to keep a small problem from becoming a big one.

By inspecting your air conditioner and replacing filters, you can ensure your system will run great all season long. As the summer progresses, perform routine maintenance and periodically check for things that could be wrong. For a professional diagnosis and preventative maintenance, contact a professional HVAC technician.

Myth No. 4: To cool a room more quickly, set the thermostat lower than your ideal temperature

Why it’s a myth: Air conditioners always cool at the same rate. So  there is no benefit to setting the temperature to 60 degrees when you want it to be 70. It will reach 70 at the same rate, no matter how quickly you want to cool your home.

Most air conditioners only operate on a set speed, but some units do offer low, high and medium settings.

Forget the myths

Don’t be fooled by air conditioning myths. Save money and make your system run great all season long by getting the facts from a qualified HVAC professional, and be prepared to handle those hot summer days.
