Why Your Heat Pump Isn’t Heating Properly

Jan 3, 2022 | HVAC

Using a heat pump is a versatile, effective way to heat your home. You can use it any time of the year. During the summer, it acts as an air conditioner and pumps cold air throughout your house. In the winter, on the other hand, your heat pump draws heat in from outside and makes your home warm and comfortable.

However, there may be instances where your heat pump isn’t achieving the ideal temperature. In this article, A/C and Refrigeration, a top HVAC company, discusses the most common problems you may experience with your heat pump. 

Clogged air filters. The main purpose of air filters is to catch debris. However, when they get too dirty, they can restrict airflow through the system and prevent air from reaching the evaporator coil, where heat is usually exchanged. For this reason, it’s important to replace clogged air filters immediately. Make sure to change your filter as per the frequency recommended by the filter manufacturer. 

Low refrigerant charge. Many homeowners think that refrigerant is only for cooling purposes, but heat pumps rely on their refrigerant all-year-long to transfer heat between your home’s air supply and the air outdoors. If your refrigerant levels are low, your heat pump may have a difficult time bringing your home to the ideal temperature. In cases like this, you’ll have to call a professional technician for HVAC repair. They’ll evaluate your refrigerant levels to determine if the system needs to be recharged. 

The outdoor unit is blocked. Remember that your heat pump pulls heat from the air outside into your house. When the outdoor unit is blocked by debris, however, there won’t be enough air movement, which means there won’t be enough heat extracted to keep your house warm. Fortunately, it’s easy to remedy this problem. All you have to do is clean your outdoor unit and remove anything that blocks the flow of  air. For optimal airflow, be sure to keep at least two feet of clearance around the outdoor unit. 

The outdoor unit has no power. If you notice your blower is blowing cold air into your house instead of warm air, your outdoor unit may have no power. Thus, you’ll need to check the thermostat and make sure it’s set on “heat.” Don’t forget that the thermostat setting should be higher than the indoor temperature to initiate a heating cycle. If the outdoor unit’s circuit breaker was tripped, you’ll need to reset it. If there’s still no power, you may need to call a technician.
