If you own a home or commercial property, you probably know a thing or two about AC repair. However, with any bit of knowledge, there will be a few gaps that make you wonder if what you’ve heard is true. While there are some ways that caring for your air conditioning unit hasn’t changed, other aspects will need a little extra attention these days. Here are five AC repair myths that could be costing money and time, and you should stop following.

#1: Yearly maintenance isn’t that important.

As air conditioning units have evolved throughout the years, the way they’re handled and built has changed and improved. However, while these systems have advanced, that doesn’t mean that you don’t need to get the yearly maintenance. Without this, you’ll find that you end up getting more costly repairs and your unit simply doesn’t perform in prime condition.

#2: You should always set your thermostat to the desired temperature.

Sure, we would all love to live in seventy-two degrees temperatures even when it’s one hundred and five degrees outside. However, this can wreak havoc on your unit and cause you to have more frequent breakdowns that require AC repair. Even the best units will have a hard time keeping a home or large space cooled over thirty degrees below the temperature outside. If you want to keep your space cooler, then be sure that other areas of your home or energy efficient such as windows.

#3: You don’t need to learn about the AC repair company you hire.

There are a lot of people out there that claim they can handle your AC repair needs, and while this may be true, it doesn’t mean that they are a reputable company with all of the proper certifications, insurance, and licenses. Take care in finding an AC repair company that can be easily reached and has a positive reputation in your community.

#4: Air filters need to be cleaned or changed the same for every unit.

What works for you and your unit doesn’t mean it works for everyone else. The different units will have an impact on this, as well as the style of filter you choose. Another thing to take into consideration is the number of people that live in your home if you have pets and the types of dander that will be going through the filter. The more traffic you have going in and out, the more often you’ll need to clean your filter.

#5: Commercial and residential AC units need the same care.

If you have a company tell you that commercial and residential AC repair and units are the same, then you may want to get a second opinion. There are similarities, but commercial air conditioning units will require a special set of skills and education. Make sure that the AC repair company you hire for your commercial needs has an in-depth understanding of the different types of units and how to care for them.
