As temperatures start to decrease, having a working heat pump in your Apison, TN home is a must. If your heat pump is blowing cold air when it shouldn’t, it could point to various issues. Let’s review some of the most common heat pump problems that can cause your system to blow cool air in heating mode.
Broken Thermostat
Sometimes, the thermostat may be the source of heat pump issues. If the thermostat won’t detect temperatures accurately or the wiring has a connection problem, this can cause a signal malfunction and result in cold air from your system.
Refrigerant Leak
If your heat pump’s refrigerant is leaking out, this can cause unwanted cooling, in addition to more serious problems. It’s best to consult a technician quickly because leaking refrigerant can eventually cause the heat pump to stop working.
Dirty Coils
In a properly functioning heat pump, the coils draw in heat from the surrounding air. However, if the coils are dirty, this can result in a reduction in heat absorption and cause the pump to run incorrectly.
Broken Reversing Valve
The reversing valve helps the heat pump to switch modes between heating and cooling. If this is no longer working properly, the pump may still blow cold air despite being set to heat.
Dirty Air Filter
A dirty air filter will restrict airflow, which causes a reduction in air cooling inside the system. It can also cause the heat pump to work harder than usual to cool the air and potentially malfunction. It’s best practice to change the air filter every few months to ensure efficient operation.
