We understand that a suddenly non-working air conditioning system in your home during a hot summer day can bring on panic. We’re expecting extreme heat this summer, and central air conditioners are vital for getting through many sweltering days. If you have to confront a cooling system that isn’t cooling, you might be ready to try anything to get it working again.
Usually, the best way to restore your cooling is to call for professional air conditioning repair in Potomac, MD from our experts. If you want to know what repairs you can do yourself, the answer is that there aren’t any. A “repair” means getting out the tools, opening the AC cabinets, and trying to fix whatever is wrong. Unless you are an HVAC professional with the proper training and equipment, you won’t be able to repair the AC on your own. In fact, you may make the situation worse and even void the warranty.
Just because we’re getting closer to the end of summer doesn’t mean you aren’t going to use the air conditioner for the rest of the season. There are still likely to be a few times when you’re going to need your air conditioner before it turns off for the rest of the season. For those times, it’s important that you keep an eye out for problems that might arise with the air conditioner. You don’t want to end the summer by paying high AC repair costs, after all. The following are a few of the more common problems you might run into during the next couple weeks. 
Summer is the time of year when you need to be most vigilant about detecting problems with your air conditioner.
