Summer is not a season you typically associate with ice, unless it’s the cubes floating around in a frosty beverage. However, a common problem affecting air conditioners in the summer is freeze-up. In fact, it’s one of the most frequent causes of air conditioner breakdown during the summer months. When an air conditioner freezes up, ice forms on the evaporator coils or the pipes leading away from the outdoor air conditioning unit. This can cause significant damage to your HVAC system, leading to costly repairs or air conditioner replacement. Learn why freeze-up occurs as well as how to prevent it and how to manage it if it does affect your air conditioner.

AC Troubleshooting

Any time you notice that your air conditioner is not operating at peak performance, check the outdoor unit for ice. As the evaporator coil in the air conditioner gets colder, moisture from the air can accumulate on it and freeze. If you experience freeze-up on your air conditioner, some things to look for are blocked air filters, collapsed ducts, a dirty evaporator coil or a problem with the fan. It’s also a good idea to check refrigerant levels.

Dirty air filters, blocked registers or collapsed ducts can prevent air from flowing properly through the system, causing the moisture on the evaporator coil to condense and freeze. If the fan is not blowing air through the system, it can have the same effect. Dirt buildup on the evaporator coil can also prevent it from working properly. The professionals at All Seasons Service Network near Milton, FL, can inspect your system for any of these issues and provide regular air conditioning service and maintenance to prevent them from occurring in the first place.

How to Prevent Freeze-Up

Keep refrigerant levels high to prevent the system from freezing up. This is an air conditioning service that should be conducted by a professional. At All Seasons Service Network, we can check your refrigerant levels and recharge them during our seasonal maintenance sessions. You should also change your filters regularly. The frequency depends on many factors, but a good rule of thumb is to change your filters once every month or once every other month. Finally, do not run your air conditioner when the temperature outside is cooler than 60 degrees. Instead, take advantage of the cooler weather and open the windows.

Whether your HVAC system is new or old, it is important to maintain it properly and pay attention to its operation. A poorly functioning unit may require maintenance or repair. If you have an outdated unit, it may be more efficient to replace it with a new Carrier system from All Seasons Service Network.
