In our most recent articles we’ve been telling you about what to look for when it’s time for AC service. Some problems, such as weird smells or strange noises, could signal that it’s time for AC repair. Other problems, like constant repairs or extreme electricity bills in the summer, could suggest that it’s time for new AC installation. (Don’t worry, JC and JC HVAC Mechanical Contractors has financing options so that you can get your air conditioner replaced immediately and pay it off over time.)

We threw a lot of information at you in those blogs, information gained from decades in the HVAC repair business. But we also know that you might be getting some information from other sources, and we all know how unreliable the internet can be when it comes to getting true information regarding anything, let alone heating and cooling topics. Here are a few myths and misconceptions about air conditioning and AC service that you might have heard. As it turns out, there are quite a few!

MYTH: Ceiling Fans Make an Air Conditioner Turn On Less Often

Much like the heat from a stove and the heat from a hot pepper are different, so is the cool from an air conditioner and a ceiling fan. The air conditioner is actually blowing cold air, while a ceiling fan is blowing air over your skin and removing the heat from it.

It might seem like semantics, but it’s not. Here’s what it comes down to: fans don’t actually cool the air. (In actuality, they warm it up a fraction of a degree because of the heat from their motor!) The thermostat in your home isn’t cooled down by the blowing fan in the same way as your skin is, so it’s going to tell the air conditioner to turn on when it reaches a certain temperature in the room…whether ceiling fans are on or not.

Air conditioners will keep a room cool even if you’re not there, so there’s no harm in leaving the AC on even if you leave the house. But if you leave a room, make sure to turn the fans off so that you’ll save electricity.

MYTH: Get the Biggest Air Conditioner During AC Replacement

It’s understandable why this myth keeps cropping up. After all, a bigger air conditioner will cool things down more quickly, right? So when it comes time for new AC installation, you should probably upgrade to a bigger unit.

Again, this is a myth. An air conditioner should be matched to the size of the house, the square footage being cooled, and the efficiency of the ductwork design. AC units that are too big for the space won’t necessarily cool things down any faster, and they’ll waste energy due to their sheer size. When it comes time for an air conditioner replacement, JC & JC HVAC Mechanical Contractors will make sure that you’re getting the right-size air conditioner for your home’s needs.

MYTH: An Air Conditioner Is the Only Summer Cooling You Need

When spring arrives, ceiling fans and open windows are pretty much all you need. But when it gets to be the middle of summer, it’s time to turn on the air conditioner. So you’re done, right?

We’d like to suggest another step in your quest for the most comfortable temperature and the lowest utility bills: window dressing. While big, uncovered windows are an excellent way to let the heat in during winter, they’re doing the same thing in summer unless you cover the windows in some way and block the sun. White blinds can do a good job, as they reflect the heat back outside.

MYTH: An Air Conditioner Only Cools The Air

When Willis Carrier invented the air conditioner, he did an excellent job naming it. He didn’t call it an “air cooler” or an “air coldifier.” He called it an air conditioner, because his invention was about much more than just cooling the air.

Yes, air from an air conditioner is colder, but it’s also conditioned so that it has less humidity. So when you walk into an air-conditioned building from the muggy outdoors, it’s more than just the cold nature of the air that’s helping. High humidity in your home is a good indication that something is wrong with your air conditioner and that it’s time for AC repair. If you notice that your air is cool but still feels clammy, be sure to call an AC service.

MYTH: Overshoot the Temperature To Cool the House Faster

Here’s there scenario: You come home and find the house at 85 degrees. You want it at 75 degrees, so you keep pushing the button until you set the thermostat for 65 degrees. That’ll cool the house faster for sure!

While everyone wants this method to work, it doesn’t do anything to help cool the house any faster. The air conditioner will cycle on and off as much as it needs to in order to get to a specific temperature, and the laws of thermodynamics won’t let it reach that lower temperature any faster! All that will end up happening is that you’ll end up making the house too cold, which just wastes energy and might even make you uncomfortable until you hit “run program” or a scheduled temperature change occurs.

MYTH: “I Don’t Need To Change My Air Filter”

Air filters in your HVAC unit are the first line of defense against dust and dirt moving through your home. While many people know that air filters are important to a system, far too many of them think it’s okay to get them changed twice a year when we stop by for AC and furnace maintenance.

Air filters need to be changed more often than every six months. Most manufacturers suggest changing them out every three months, and it’s a simple process. (We can even teach you how to do it.) Failing to switch out old ones for new ones can cause a strain on the system and wastes energy as the blower has to work harder to move the air.

Did You Believe Any Of These Myths?

If you were a true believer in any of these myths and misconceptions, don’t be ashamed. Some of them have a tinge of logic to them even if they’re wrong, so it’s easy to see why the ideas proliferate.

But we’re not done yet! With air conditioners being such a major part of American life during the summer, there are certainly more than six myths going around about them. In our next article we’ll discuss six more pieces of false information that get around about cooling the air indoors. Until then, we hope that you don’t have any trouble with your AC as trouble approaches. Still, spring is a great time to have AC maintenance performed, so contact JC & JC HVAC Mechanical Contractors for a tune-up today!
