When your heat pump continues to run for many months at a time like it does in Lakewood Ranch, FL, you may not notice signs of damage or wear. If ice starts to build up on the exterior of your heat pump, there is an underlying problem that needs to be addressed before costly repair or replacement is needed. Here are some causes of icing on heat pumps.
Dirty Air Filters
A clogged air filter could be the cause of ice. If your air filter is in need of replacement, dirt and debris on the filter could be causing the evaporator coil in your heating system to freeze up. When air is not properly conditioned and moved through the system by coils, the coils may freeze up. The result is a buildup of ice on your heat pump. A replacement of the air filter often solves this problem by allowing air to flow more freely through your heating system.
Faulty Components
If an individual component in your heat pump goes bad, your entire heating and cooling system can malfunction. Fortunately, this issue often requires just the replacement of the faulty component. If the thermostat is not working properly, improper temperature control may be causing your pump to ice over. In this case, you may notice that the temperature in your home does not match the thermostat setting before you spot the ice on your outside unit.
Refrigerant Issues With Your Heat Pump
Leaking refrigerant can also lead to a buildup of ice on the outside unit. Low levels of refrigerant cause coils to become too cold. These cold coils can cause ice to form on the outside unit. In this case, it is essential to contact a professional to have levels adjusted and leaks repaired before bigger problems develop.
