Heat pumps are an efficient way to heat and cool your home by moving heat instead of generating it like a furnace system does. In order for a heat pump to perform efficiently as it is intended, it should be maintained and working properly. Just like any heating and cooling system, heat pumps can develop a number of problems. Gillece HVAC Services can help you determine if your heat pump is working correctly.

How a Heat Pump Works

First, it’s good to know how a heat pump works in order to figure out when something may be wrong. Common air-source heat pumps consist of a compressor and two coils. Refrigerant in the outdoor coil extracts heat from the outside air and evaporates it into a gas. The indoor coil releases the heat into your home. For cooling, a reversing valve changes the direction of refrigerant flow, which is also used to defrost the outdoor coil during winter.

Common Heat Pump Problems

One problem that you may run into if you have an auxiliary system is the electrical coils take over to help the heat pump extract heat when outside temperatures are too low. This can also happen if there is a problem with the outdoor coil, which you may never know until you receive a significantly high electric bill. It’s a good idea to have the outdoor component checked periodically to ensure everything is working smoothly. Gillece HVAC Technicians help to check that each part of a heat pump is operating normally.

Other heat pump problems include low airflow, leaky ducts and incorrect refrigerant charge. You may need to call for professional assistance to clean the evaporator coil to increase airflow, or to address ductwork or refrigerant issues. Any of these problems can reduce the performance and efficiency of a heat pump.

When a Heat Pump System Works Correctly

Some signs that your heat pump is working correctly include:

  • The system is generally quiet; there shouldn’t be any groaning or creaking noises or sounds that might indicate an overworking motor
  • Airflow is sufficient, flowing smoothly, without odor or dust and dirt
  • The system responds quickly to any thermostat changes while working evenly

If you think there is a problem with your heat pump and you can’t get to the bottom of what’s wrong, call for a professional HVAC inspection. Gillece HVAC Technicians can help you figure out if your heat pump is working correctly, for a comfortable home you can rely on from season to season.
