There are many reasons your heat pump might not be blowing hot air. In this blog post, we will go over four of the most common causes of this problem. Stay tuned; we will help you get your heat pump blowing hot air in no time!
Dirty Air Filter
A dirty air filter is one of the most common reasons for a heat pump not blowing hot air. The air filter is responsible for trapping dirt, dust, and other airborne particles that can accumulate over time and clog the system. The fan pulls air through the filter and into the unit when the heat pump is turned on. If the filter is clogged, it will restrict airflow and cause the heat pump to overheat. As a result, the heat pump will cycle on and off more frequently in an attempt to cool down, which can reduce its overall efficiency. In some cases, a dirty air filter can also cause the heat pump to shut down completely. Therefore, checking and cleaning the air filter regularly is vital to ensure that it does not cause the heat pumps not blow hot air.
Low Refrigerant Charge
Low refrigerant charge is one of the most common causes of heat pumps not blowing hot air. For a heat pump to work correctly, it must have the right amount of refrigerant. If there is not enough refrigerant, the heat pump will not be able to circulate heat effectively. As a result, the air from the vents will be cooler than usual. In some cases, low refrigerant levels can also cause the outdoor unit to freeze up. If you suspect that your heat pump has a low refrigerant charge, it is vital to have it checked by a qualified technician. Otherwise, you may find yourself without heat on a cold winter day.
Dirty Outdoor Unit
Several things can cause a heat pump that is not blowing hot air, but one of the most common causes is a dirty outside unit. The outdoor unit of a heat pump is responsible for drawing in the air; if the unit is dirty, it can restrict airflow. As a result, the heat pump will not be able to draw in the air effectively, resulting in lukewarm or even cold air being blown into the home. In some cases, a dirty outside unit can also cause the heat pump to overheat, leading to damage. If you notice that your heat pump is not blowing hot air, one of the first things you should do is check the outside unit to see if it needs to be cleaned.
Damaged Reversing Valve
If your heat pump is not blowing hot air, it could be due to a damaged reversing valve. The reversing valve is responsible for switching the direction of refrigerant flow in the system. If it becomes damaged, it can cause the refrigerant to leak out, preventing the heat pump from being able to circulate warm air properly. In some cases, the reversing valve can get stuck in one position, causing the heat pump to blow cold air constantly. If you suspect that your heat pump’s reversing valve is damaged, it is essential to have it checked by a qualified technician as soon as possible. If left unchecked, a damaged reversing valve can cause severe damage to your heat pump and lead to costly repairs.
You now know the likely causes for why your heat pump is not blowing hot air. If you check each of these things and your heat pump still is not fixed, then it may be time to call in a professional. With some troubleshooting, you should be able to get your heat pump back up and running again in no time!
