Troubleshooting Common Issues with Heat Pumps

Try these simple tips before paying for a heat pump repair

Heat pumps are an increasingly popular choice for many homeowners in Wrentham and across Eastern Massachusetts, offering an energy-efficient way to heat and cool homes. Like any HVAC system, they can run into occasional problems, but heat pump function differently from furnaces, boilers or central air conditioning systems. They don’t generate heated or cooled air — instead, they transfer heat between the inside and outside of your home.

The good news? Many of these issues can be identified and resolved without the need for a professional service call. Below, we’ll cover some of the most common heat pump issues and how to troubleshoot them.

Heat Pump Isn’t Turning On

If your heat pump isn’t turning on, start with these simple troubleshooting steps:

1. Check the power supply. Ensure the system is plugged in and that the power switch is turned on. Examine your circuit breakers to see if any have tripped.
2. Thermostat settings. Verify that your thermostat for your air handler is set to the correct mode (heating or cooling) and that the temperature setting is appropriate for your needs.
3. Outdoor unit blockages. Debris or dirt around the outdoor unit can sometimes interfere with its operation. Clear away leaves, branches or anything else that could be obstructing airflow.

If the heat pump still doesn’t start after these steps, it may require professional attention.

Heat Pump is Blowing Warm Air in Cooling Mode

Is your heat pump blowing warm air when it’s supposed to be cooling? This issue can be caused by a few different factors:

1. Dirty air filters. Clogged air filters restrict airflow, making it harder for your heat pump to cool your home efficiently. Check them each month in the peak heating and cooling seasons and clean them if necessary.
2. Thermostat issues. Double-check that the thermostat of your air handler is correctly set to cooling mode.
3. Low refrigerant levels. Insufficient refrigerant can significantly impact your heat pump’s cooling capacity. This issue requires professional servicing to locate and repair refrigerant leaks.

Heat Pump is Running Constantly

Heat pumps operate differently than traditional systems, often running longer to provide consistent, energy-efficient temperatures, especially when they are in heating mode. However, if your heat pump seems to run non-stop, it could indicate a problem:

1. Incorrect system settings. Make sure the temperature is set correctly, and avoid setting it too low during summer, as this can overwork your system.
2. Poor insulation. If your home’s insulation is insufficient, it might be losing heated or cooled air, causing your heat pump to cycle over and over. Improving the “envelope” of your home, including windows and doors, can help.
