A heat pump freeze-up generally indicates that your system’s components are not functioning properly. A stopped or stalled heat pump will require more energy to operate and may not efficiently cool your Braselton, GA home. Here are common reasons why your heat pump may be freezing up.
Blocked Air Filters
When air filters gather particulates for an extended period, they become clogged. This can restrict circulation and trap moisture.
Some of the things that can block your filter include dust, smoke, and pet dander. We suggest replacing your filter at least every three months.
Dirty Evaporator Coil
The evaporator coil of your heat pump allows refrigerant to flow through it. The evaporator coil facilitates the transfer of heat into your house during cooler weather and the drawing of heat out during sweltering conditions.
When the evaporator becomes dirty, it loses its ability to transmit heat. If you detect frost on your heat pump coils, turn it off and contact a reliable HVAC company for assistance.
Dirty Fan Blades
Whenever you have dirty blower fan blades, the system’s ventilation and exhaust output suffer. This can trap moisture and make the unit freeze up. If this occurs, please contact an HVAC expert immediately because the fan blades are quite fragile.
Low Refrigerant
If your unit is running out of refrigerant, it could be leaking. This could be due to a weakened solder connection, a broken valve, or loose fittings. Furthermore, when a part rubs against the refrigerant container over time, it may ultimately puncture it, causing a freeze-up.
When the lines start producing rattling noises, turn off your unit to be safe. Then, call an HVAC professional for an urgent inspection.
