Comprehensive Guide to Troubleshooting Heat Pump Issues
It’s critical to begin troubleshooting as soon as the winter chill arrives and your heating system is unable to reach the appropriate room temperature. It’s helpful to know how a heat pump works since even if it’s operating properly, you may still feel uncomfortable. Thermostat settings, unusually low outdoor temperatures, or a clogged air filter are frequently the cause of the issue.
Heat Pump Not Cooling
Sometimes a heat pump—which works in the summertime like an air conditioner—may not be able to chill a space efficiently. There could be a number of difficulties, including filthy or clogged filters, an unclean outdoor coil, troubles with the interior or outdoor unit, and thermostat settings. Let’s examine these in more depth:

Thermostat Settings: Ensure the thermostat is correctly set. If it’s on heat mode or the constant fan setting, it might be operating but only blowing warm air. Adjust the thermostat to the cool or auto setting. Lower the temperature by a few degrees and observe if the room temperature changes.
Outdoor Unit Issues: Check for a tripped circuit breaker and visually inspect the outdoor unit to ensure it’s operational. If the circuit breaker frequently trips, it could indicate a malfunction, a broken component, or an electrical problem.
Indoor Unit Issues: If the heat pump is running but emitting warm air, and the thermostat is set correctly, you might be low on refrigerant or have a faulty reversing valve. If there’s no airflow, check the power switch or circuit breaker.
Dirty/Clogged Filter: A blocked filter or obstructions in the indoor blower can restrict airflow, resulting in weak or no air entering your home. Inspect and clean or replace the air filter if necessary.
Dirty/Clogged Outdoor Coil: Debris like cottonwood or dirt can accumulate on the outdoor coil, impeding its ability to transfer heat effectively. Clean the outdoor coil during regular system maintenance.
These are just a few common, quick fixes for heat pumps that aren’t cooling. For more extensive issues or emergency repairs, it’s best to contact a professional HVAC dealer. Your comfort and energy bills will thank you for it.
When to Call an Expert for a Malfunctioning Heat Pump
Heat pumps can be complicated devices, and although most problems can be fixed quickly and simply by the typical homeowner, some repairs require an HVAC specialist with the necessary training to identify and fix the issue. In these situations, it’s best to get in touch with your neighbourhood BCRC Heating HVAC dealer before a minor problem becomes more serious and requires repair.

Common Heat Pump Problems and Solutions
As summer temperatures rise, Why Heat Pump Not Cooling your home is a problem you’ll want to remedy promptly to ensure comfort and safety. Various problems can cause your heat pump to malfunction, so here are some common scenarios:
Heat Pump Not Turning On: If your heat pump fails to turn on, consider these potential causes:
Thermostat Issues: Verify that the thermostat is set to “cool” and the desired temperature is below the home’s current indoor temperature. Check for system error messages or alerts on smart thermostats.
Power Supply: Ensure the heat pump is receiving power. If the unit draws too much power, the circuit breaker might trip as a safety precaution. Check the electrical panel and reset the breaker if necessary. Persistent tripping indicates a larger issue, requiring a technician’s attention.
Start Capacitor Problems: Listen for a faint clicking noise when the heat pump attempts to start. This noise might indicate a broken start capacitor, which helps the motor start with less effort. Contact an HVAC technician for replacement.
Reversing Valve Malfunction: If the unit is only delivering warm or cool air, a technician might need to repair or replace the reversing valve, which allows the system to function as both a heater and air conditioner by reversing the refrigerant’s direction.
Why Heat Pump Not Cooling: If your heat pump is running but your heat pump not cooling effectively, it could be due to:
Thermostat Malfunction: Ensure the thermostat is set to “cool” with the desired temperature. If it’s not reading the indoor temperature correctly or there’s an electrical issue, a professional technician is needed.
Reversing Valve Issues: If the air from your vents is hot, the reversing valve might be malfunctioning.
Dirty Components: Limited airflow due to dirty or clogged components, or a clogged air filter, can cause the system to expel lukewarm air. Clean debris from the outdoor unit and replace the HVAC filter if necessary.
Low Refrigerant: Low refrigerant levels or a leak can hinder the heat pump’s cooling ability. Regular maintenance is crucial for identifying refrigerant issues or potential leaks.
Heat Pump Running Constantly: A continuously running heat pump can spike your energy bill and shorten the unit’s lifespan. Common reasons include:
Extreme Thermostat Settings: Setting the thermostat too high or low can cause the unit to work continuously. Adjust the thermostat by a few degrees to give the unit a break and reduce energy consumption.
Dirty Air Filter: A clogged air filter can obstruct airflow, making the heat pump work harder. Replace the filter every 90 days, or more frequently if needed, to maintain efficiency.
Compressor Contactor Issues: The compressor contactor controls power to the compressor and outdoor fan. If damaged, the heat pump might run constantly. Professional repair or replacement is necessary.
Heat Pump Not Heating: During winter, these issues might prevent your heat pump from blowing hot air:
Blocked Unit: The heat pump draws heat from the outside air, and obstructions like snow, ice, or debris can hinder its function. Clear any blockages to restore proper operation.
Clogged Air Filter: A dirty air filter can block airflow to the indoor coil, reducing heating efficiency. Regularly check and replace the filter if dirty.
Low Refrigerant: Low refrigerant levels, often due to a leak, can impair heating. A professional should check and recharge the refrigerant if necessary.
