Five Common Air Conditioning Myths

Five Common Air Conditioning Myths

Although air conditioning technology has existed for decades, many people still have trouble separating certain air conditioning facts from fiction. Over time, some of these misconceptions have come to be accepted as common knowledge, so we’re here to set the record straight. Here’s the truth behind some of the most prevalent air conditioning myths.

Myth #1: The Bigger The AC Unit, The Better

Yes, the size of your air conditioner matters, but it’s more important to find a unit that is suitably sized for your home, not just the biggest one you can find. If you need an example, think how inefficient it would be to put a 12-cylinder sports car engine inside a tiny hatchback. The sheer cooling ability of an oversized air conditioner would simply be negated by the power it uses. Also, improperly sized air conditioners tend to cycle more frequently, which leads to quickened wear and tear.

Myth #2: Setting Your Thermostat Very Low Cools Your Home Faster

One of the longest-lasting air conditioning myths states that you can cool your home quickly by dropping your thermostat temperature super low. Unfortunately, this just doesn’t work. Your air conditioner works equally hard whether you’re trying to cool your home by one degree or 15 degrees. The best course of action is just to set your thermostat exactly where you need it.

Myth #3: Close Vents In Rooms You Don’t Use

While it may feel like you’re helping by not “wasting” cold air on unused rooms, you should still keep vents open whether or not a room is being used. Closing off vents actually throws off the delicate balance of air distribution through your home. By closing vents, all you’re doing is cooling the inside of your air ducts.

Myth #4: Air Conditioning Only Cools Air

Cooling your home is obviously the biggest benefit of air conditioning. However, setting a comfortable temperature inside your home is only one thing that your air conditioner does. As the name suggests, your AC unit is conditioning the air by removing humidity.

Myth #5: Thermostat Placement Doesn’t Matter

This might be something you’ve never even considered, but the placement of your thermostat can significantly affect your home energy efficiency. Obviously, it should be mounted in a place that allows for convenient adjustment. Beyond that, the U.S. Department of Energy suggests it should also be on an interior wall, kept away from any direct sunlight, drafts, doorways, skylights, and windows. Also, furniture should not be placed below or in front of your thermostat.
