Heat Pump Troubleshooting: 10 Common Heat Pump Issues

Because they can heat and cool effectively while using little energy, heat pumps are gaining popularity as an alternative to traditional heating devices. For instance, an air-source heat pump can deliver 1.5 to 3 times as much heat energy to a home as it does electricity energy by transferring heat between the air within and outside of your home. Additionally, they are a popular investment for homeowners because of their energy and financial efficiency.

10 Common Issues and How to Troubleshoot It:

Your heat pump works exactly like a central air conditioner and has the added advantage of heating your house in the winter. The following are a few of the typical difficulties mentioned in this heat pump troubleshooting guide:

  • Blowing chilly air when on hot.
  • Not cooling with a heat pump.
  • The heat pump functions continuously in a comfortable climate.
  • The unit outside is blocked.
  • The pump heater is not heating.
  • Short cycling in the heat pump.
  • The unit outside is frozen.
  • The indoor air handler’s fan is not operating.
  • A heat pump does not alternate between heat and cool.
  • The heat pump is not operating

1. Blowing chilly air when on hot:

There are a few typical issues you can fix without ever touching the heat pump itself if your heat pump system is blowing cold or room temperature air while the thermostat is set for heat mode. Make sure the system isn’t unintentionally switched to cooling by checking twice. Check the fan control settings as well. These problems should be resolved by resetting the system to heat mode and the fan to automatic. If the issue persists, you’ll need to start paying closer attention to the interior and outdoor units, as shown below.

2. Not cooling with heat pump:

Have you experienced a heatwave while your heat pump malfunctioned? Not to worry! Instead, review these potential causes and solutions for why your heat pump may not be cooling. Make sure the cool setting is selected on your thermostat. If the settings are perfect, your thermostat may not be properly calibrated. To figure the problem with your thermostat, you can perform several troubleshooting procedures.

3. The heat pump functions continuously in a comfortable climate:

It can be normal for a heat pump to run continuously in extremely cold weather as it attempts to extract enough heat for your home because the device draws its heating energy from the outdoor air. However, if the outside temperature is just moderately warm and the unit is still having difficulties or running nonstop, it’s time to perform some heat pump troubleshooting.

Check the thermostat settings first. Are you sure the heat pump is set to cool? If so, switching to the heat setting ought to solve the issue. Your heat pump might require maintenance if the problem is not with the thermostat setting. Regular heat pump maintenance performed by an experienced, licensed HVAC expert can result in improved operating efficiency and more dependable comfort.

4. The unit outside is blocked:

For your heat pump system to operate successfully and efficiently, the outdoor coil must have unhindered air movement. Check the outdoor unit for too much debris, such as leaves or snow obstructions, if your system is not heating up or is running nonstop. If the device is blocked or obstructed in any way, get rid of the obstruction, then start checking the temperature inside again. It’s time to consult a professional if you are still experiencing problems after completing the remaining troubleshooting steps.

5. The pump heater is not heating:

Make sure your thermostat is in cooling mode. Check to see if your fan is operating continually if that is not the case. The system is not actively heating if your fan is on all the time. After that, switch the fan to automatic and the system to heat mode.

6. Short cycling in the heat pump:

Your home will cool or heat up too quickly if your unit is too big for it. It will turn off when it reaches the specified temperature. Your system may overheat if your air filters are unclean since they can limit airflow. Therefore, as a protective measure, your heat pump turns off.

7. The unit outside is frozen:

Your system won’t be able to generate enough heat to melt wintertime ice buildup if it is low on refrigerant. Your indoor coil most likely froze over the summer, and in either scenario, the heat pump needs to work harder to keep you comfortable. A skilled HVAC technician should test and charge the system. The fan pulls air through the coil in your outside unit, contributing to the crucial heat transfer process necessary for both heating and cooling your home.

8. The indoor air handler’s fan is not operating:

Your indoor air handler could not be turning on if your outside unit is running but there is no air flowing from the registers. When troubleshooting a heat pump for typical issues that could prevent your interior unit from turning on, look for the following:

  • The breakers for your indoor and outdoor units are separate.
  • A burnt-out or disconnected wire could be the cause of an air handler that isn’t working properly. To diagnose and fix, speak with a Carrier dealer in your area.

9. A heat pump does not alternate between heat and cool:

The heat pump’s ability to flip from one mode to another is controlled by the reversing valve. Your heat pump can now heat and cool your house by switching the refrigerant flow. The reversing valve is broken if your heat pump cannot switch between modes or operates well in one mode but not the other.

10. The heat pump not operating:

Your unit is not getting enough fresh air if your air filters are dirty and blocked. Your starter capacitor may be defective if you hear a slight clicking sound coming from your heat pump when you try to turn it on.
