Why is My AC System Freezing Up?

Air conditioning units are an extremely important piece of equipment when it comes to being comfortable during Phoenix’s punishing summers. Unfortunately, your AC unit is just like everything else in your home: it’ll probably break just when you need it most.

The coil in the AC unit can freeze, rendering your system absolutely useless. When your AC keeps freezing up in Phoenix, it can mean a nightmare for you and your family.

Fortunately, there are steps you can take to keep your system in good working order. By keeping an eye on a few things, you can greatly reduce the likelihood that your system will stop functioning during the hottest part of the year.

Leaks in the System

One of the most common causes of your AC freezing up is a leaky refrigerant system. Leaks can cause freezing and may even point to a bigger problem with your air conditioning system.

Some leaks can be fixed quite easily, but others require professional repair technicians like the ones we employ at ACE Home Services. It’s important to keep in mind that sometimes it’s better to replace than repair and talking to one of our knowledgeable technicians can help you make the best decision about your system.

Repairs can be less costly than replacement, but if your system is already on its last legs, it may make more sense to invest in a new one, rather than spending money on stopgap measures.

Restricted Air Flow

Along with coolant leaks, dirty filters are one of the most common causes of an AC unit icing up during operation. Dirty filters restrict air flow through the AC unit, so condensation that normally forms on the system is no longer dried in a timely manner. Instead, it sits on the cold compressor lines and freezes, resulting in a unit that no longer works properly.

This is one of the easiest to prevent and least costly causes of poor air conditioner operation in Phoenix. You can do your part by making sure you change the air filters for your unit regularly or set up regular maintenance calls with one of our technicians to keep your system running smoothly.

Age & Size of the System

Dealing with an older system, or one that isn’t suited to sufficiently cool your home can mean big problems during Phoenix’s hot summers. Older systems are more prone to the problems that lead to the AC coil freezing up, but so are systems that are too small (and therefore have to work too hard) to keep your home comfortable.

Old systems, or ones that don’t have the correct SEER (Seasonal Energy Efficiency Ratio) rating for your home, should be replaced as soon as possible. Otherwise, you will likely continue to have problems with your AC coil freezing up.
