We wanted to help out our customers and let them know why that might be happening.
Causes of Heat Pump Icing in McKinney
Believe it or not, there are actually normal reasons why your heat pump might start to form ice on its outdoor condensing coils. This typically happens during the winter when the air outside is cold. As your heat pump pulls heat out of the air, the moisture in the warm air releases and freezes against the coils. This is the same reason why your cold glasses gather water on a hot day.
Here are some other causes of heat pump icing that aren’t normal and could be a problem.
- Clogged air filter – This is probably the most common cause of heat pump icing. Your heat pump has an air filter in it that keeps dust and dirt from getting inside of it. If it starts to get clogged, it will restrict the flow of air through the system. This can cause the condensate lines to freeze.
- Low refrigerant – If the refrigerant levels in your heat pump are too low, it can cause them to freeze as well.
How to Prevent Heat Pump Icing in McKinney
Probably the best way to prevent heat pump icing is to get it regularly maintained by a professional McKinney heating technician. Many of the common causes of heat pump icing are lack of attention and maintenance. During regular maintenance visits, your heating technician will check your heat pump air filter as well as the refrigerant levels. This will make sure that your heat pump continues to operate properly and not ice over.
