Air Conditioning Facts: Truth or Myth?

August 14, 2012

There are a lot of myths about central air conditioning, and since keeping your home comfortable is a top priority—especially with the steamy summer we’ve been having—it’s important to know what’s true and what isn’t! That’s why Rick’s Heating & Cooling, your air conditioning experts in the Cincinnati area, has collected the five most common air conditioning “facts” that are spread around, and we’ll let you know what’s true and what is just a myth.

Air Conditioning Fact 1

Setting the temperature really low on the thermostat—below the actual temperature you want to achieve—will cool your home faster.

Myth! This is one of the most common air conditioning “facts” being circulated, and it’s just not true! Your air conditioning is either off or on—it can’t kick it into turbo drive to cool your home any faster. So, if you want to cool your home to 70 degrees, setting the thermostat to 50 degrees isn’t going to make things cooler any faster. In fact, you run the risk of wasting energy as your air conditioning continues to run after the 70 degree mark has been reached. Setting your temperature lower on the thermostat will make things no cooler than setting your GPS to Cleveland would make your trip any shorter if you were trying to drive from Cincinnati to Columbus—putting in Cleveland as your final destination isn’t going to make you get to Columbus any faster.

Air Conditioning Fact 2

You should always leave the ceiling fan on, even if no one is in the room, so it will continue to cool it.

Myth! Actually, you should always turn ceiling fans off whenever leaving a room for an extended period of time. The ceiling fan doesn’t actually cool the room itself, it just circulates the air and makes you feel cooler and more comfortable. When you’re not in the room, you actually run the risk of raising the temperature because the motor spinning the fan can put off a small amount of heat. However, using your ceiling fan in the summer and setting the temperature a little higher on your thermostat can actually help increase your overall energy efficiency—and that’s one of the air conditioning facts you can live by!

Air Conditioning Fact 3

It’s more energy efficient to leave your air conditioning running at the same temperature while you’re not at home because it will cost more to re-cool the house once you’re at home.

Myth! Here’s another example of air conditioning “facts” that most people believe, but turn out to be nothing more than a myth. It’s actually incredibly inefficient (and expensive) to leave your air conditioning running all day at the same low temperature if you’re not there to enjoy the benefits. That’s why so many people are installing programmable thermostats for their central air conditioning—that way, they can program their AC to raise the temperature during the day when they’re not home and lower it again just before they get home.

Air Conditioning Fact 4

Purchasing an energy efficient air conditioning always reduces your utility bills.

Myth! An energy efficient air conditioning system will only help reduce your utility bills if it’s properly sized and installed. If you purchase an air conditioner that is too big for your home, assuming it will be able to cool it faster, think again! Oversized ACs have a difficult time removing humidity while undersized systems struggle to cool your home and never get to cycle off—both waste your energy and money! Unfortunately, knowing which air conditioner is the right size for your home can be difficult. It’s best to contact an HVAC professional to help correctly size and install your air conditioning so you never have to worry about its efficiency.

Air Conditioning Fact 5

Your air conditioner will perform the same no matter where or how it’s installed.

Myth! As far as air conditioning “facts” go, this one is the worst because so many companies want you to believe that your system will work exactly the same and be exceptionally efficient no matter where (or how well) it’s installed. In fact, much like the size of your system being important, the quality of the installation is crucial to the performance of your air conditioning. Your system should be installed in the shade or out of direct sunlight, whenever possible, and the thermostat shouldn’t be placed near lights or other electronics that could be giving off heat and messing with your temperature sensor. When you want to have an air conditioning installation in Cincinnati or the surrounding areas, make sure you contact a company you can trust with the installation. The experienced professionals at Rick’s Heating & Cooling can help you size, place and install the best air conditioning system for your home.
