5 Reasons Your Heat Pump is Not Generating Enough Heat

Usually, when a heat pump doesn’t heat enough, the issue is caused by a dirty air filter or incorrect thermostat settings. You can quickly fix the problem by cleaning/replacing the air filter or changing the thermostat settings. However, sometimes the issue might be caused by a malfunctioning component or worn-out part. In such cases, it’s best to let a furnace repair in Tacoma deal with the issue. Continuing the discussion, here are some reasons a heat pump won’t generate enough heat.

Faulty Thermostat

Sometimes, the heat pump is working fine, and the issue is with the thermostat. If you have a faulty thermostat, it won’t relay the required signal to the heat pump, and as a result, your heat pump will not generate enough heat. Try changing the thermostat batteries and ensure that the thermostat is set to the right temperature. You may also have the thermostat checked by a technician.

Clogged Air Filter

If not cleaned/replaced regularly, air filters get clogged with dust, dirt, and dander. And a clogged air filter not only leads to an increased load on your heating system but also leads to reduced airflow, resulting in inadequate heating. A dirty air filter can also cause the motor to overheat and the system to break down. So, if you want to avoid a costly heating repair in Auburn, clean/replace your air filters regularly.

Low Refrigerant Level

The refrigerant is responsible for transferring heat from the outdoor coils to the indoor coils, facilitating heating in any indoor space. But as the system gets older or sometimes due to issues such as poor heat pump installation in Federal Way, WA, or overtightening of the flare connection, there could be a refrigerant leak. A low refrigerant level, in turn, reduces the heat-transferring capacity of your heating unit. While you can easily change your air filter yourself, you must always seek professional help when it comes to refrigerant-related issues.

Blocked Outdoor Unit

As mentioned, a heat pump works by drawing heat from the outside through the outdoor unit. If not maintained regularly, the accumulation of dust, dirt, and other pollutants on the outdoor coils tends to impede heat transfer. The issue might also be caused because of the growth of plants, shrubs, or grass around the outdoor unit. To avoid such problems, one must inspect their outdoor unit regularly and ensure the area around the unit is clear.

Bad Reversing Valve

The reversing valve is an important component of the heat pump. Its function is to reverse the direction of the refrigerant, thereby allowing heat pumps to both cool and heat any space. And though reversing valves rarely go bad, sometimes the valve might get stuck in the cooling position and prevent the heat pump from heating a space. Similarly, a defective valve coil or an internal leak in the valve may lead to heating issues.
