Comprehensive Guide to Troubleshooting Heat Pump Issues
When the winter chill arrives and your heating system can’t get the room up to temperature, it’s important to start troubleshooting right away. Understanding how a heat pump works is useful because even if it’s working properly, you may still feel uncomfortable. Often the problem is thermostat settings, unusually low outdoor temperatures, or a clogged air filter.
Heat Pump Not Cooling
Sometimes a heat pump that functions like an air conditioner in the summer cannot cool a space efficiently. There are several issues that can occur such as dirty or blocked filters, dirty outdoor coil, problems with indoor or outdoor unit and thermostat settings. Let’s examine these more closely:

Thermostat Settings Check the thermostat settings. If it is on heat mode or the constant fan setting it may be running but just blowing warm air. Set the thermostat to cool or auto. Lower the temperature a few degrees and see if the room temperature changes.
Outdoor Unit Problems: Visually check the outdoor unit to make sure it is running and for a tripped circuit breaker. If the circuit breaker keeps tripping it could be a problem , a broken item , or an electrical problem .
Indoor Unit Problems: If the heat pump is on but blowing warm air and the thermostat is set correctly, you may be low on refrigerant or have a bad reversing valve. If no airflow, check power switch or circuit breaker.
Dirty/Clogged Filter A dirty or clogged filter or blockage in the indoor blower can restrict airflow, and cause little or no air to enter your home. Check the air filter and clean or replace it, if necessary.
Dirty/Clogged Outdoor Coil Outdoor coils can pick up cottonwood, dirt, or other debris, which can restrict the coil’s ability to transfer heat. Clean the outdoor coil during normal system maintenance.
These are some common quick fixes for heat pumps that are not cooling. For more serious problems, or emergency repairs, it’s best to call a professional HVAC dealer. And your energy and comfort bills will appreciate it.
When to Contact a Professional for a Broken Heat Pump
Heat pumps are complex devices and while most problems can be quickly and easily fixed by the average homeowner, some repairs require an HVAC specialist with the proper training to identify and fix the problem. In these cases, it’s best to call your neighbourhood BCRC Heating HVAC dealer before a minor problem becomes a bigger one in need of repair.

Common Heat Pump Issues and How to Fix Them
With the increase in summer temperatures, Why Heat Pump Not Cooling your home is an issue you’ll want to address quickly to maintain comfort and safety. There are a few things that can cause heat pumps to stop working. Some of the common situations are:
Heat Pump Won’t Start If your heat pump won’t start, think about these possible causes:
Thermostat Issues: Make sure that the thermostat is in the “cool” position and that the temperature is lower than the current temperature inside your home. Smart thermostats Check for system error messages or alerts.
Power Supply The heat pump is not getting power. The circuit breaker is a safety feature that trips if the unit pulls too much power. Check the electrical panel. Reset breaker if necessary. If it keeps tripping , it has a bigger problem that needs a tech .
Start Capacitor Issues: Listen for a faint clicking sound when the heat pump attempts to turn on. This noise may be a sign of a bad start capacitor . The start capacitor helps the motor start less hard . Replacement: Call an HVAC technician.
Reversing Valve Failure If your unit is only blowing warm or cool air, a technician may need to repair or replace a reversing valve that changes the direction of the refrigerant so the system can work as both a heater and air conditioner.
Why Is My Heat Pump Not Cooling? If your heat pump is running but it’s not cooling properly it could be:
Thermostat Issue: Verify the thermostat is set to “cool” and the temperature is correct. You’ll need a professional technician if it’s not reading the indoor temperature correctly or if there’s an electrical problem.
Reversing Valve Problems If you’re getting hot air from your vents, it could be that the reversing valve is broken.
Dirty Components: Clogged or dirty components or a dirty air filter can prevent proper airflow, leading the system to blow tepid air. Clean debris from the outdoor unit if necessary and change the HVAC filter.
Low Refrigerant Low refrigerant levels or refrigerant leaks can affect the heat pump’s ability to cool. You must do regular maintenance to detect any refrigerant issue or possible leaks.
Heat Pump Runs All The Time: When you have a heat pump that runs constantly, you can see your energy bill go up and the life of the unit decrease. Typical reasons include:
Extreme Thermostat Settings The system will run constantly if the thermostat is set too high or low. Save energy and give the unit a break by adjusting the thermostat a few degrees.
Dirty Air Filter. A dirty air filter can restrict the flow of air and make the heat pump work harder. Change the filter every 90 days or as required to ensure it’s working efficiently.
Compressor Contactor Problems: Compressor contactor – Controls power to outdoor fan and compressor. A broken heat pump can run continuously. Professional repair or replacement required.
Heat Pump Not Heating These problems can cause your heat pump not to blow hot air during winter:
Blocked Unit: Heat pumps pull heat from the outside air, but snow, ice, or debris can block the heat pump. Clear blockages to resume normal operation.
Clogged Air Filter: A dirty air filter can restrict airflow to the indoor coil, reducing the efficiency of the heating. Check the filter periodically and change it when dirty.
Low Refrigerant- If you have low refrigerant levels it can affect your heating in most systems. A professional should check the refrigerant and refill it as needed.
