Air conditioning units are vitally important to any home, but even more so during those hot summer months. A day that sees temperatures stretch into the triple digits is suddenly made manageable when you walk inside and feel a blast of cold air hit you right in the face. Why then do air conditioners most often in the summer, right when you need it the most? The answer is simple: That's when you're using it the most. Even hotter areas like Arizona provide a few months of relief, allowing you to switch off your AC unit and save a little bit on energy bills.

Fortunately, most air conditioning repairs are a quick fix. Unless your unit is about to go out anyway, chances are your problems are one of the three issues outlined below.

1. Clogged Air Filter

Air filters circulate the air inside of your home, purifying the oxygen you breathe and getting out all the contaminants that can make your family sick. All of those allergens collect on the air filter, but if not changed regularly, it can get clogged and cause real circulation issues. Most experts recommend changing your air filter between every 1–6 months depending on what kind it is and how you use it. If it's been longer than that, change it immediately.

2. Broken Fan

That roaring sound you hear right before cold air starts pouring into your home is usually the outside fan. Its primary responsibility is to drive hot air out of your home, so if it's not working, your AC unit will have a hard time regulating the temperature. In some cases, the fan may not be spinning at all, which is most likely a problem with your compressor. Although you could change that yourself, it's recommended to have someone who specializes in air conditioning repair handle the job.

3. Frozen Coils

It seems weird that anything can be "frozen" in the middle of summer, but one of the most common AC repair problems are coils that have a thick layer of ice caked on top of them. Since these are used every day to help send cold air into your home, they'll inevitably develop a layer of grime that will then trap in a layer of ice, forcing only hot air into your house instead of cold. An AC repair tech will be able to clean these off rather easily and bring your unit back into proper working order.
