Heat pumps are a reliable and energy-efficient solution for year-round comfort, but occasional issues can arise. A recent customer experiencing a thermostat displaying incorrect temperatures highlights the importance of addressing problems promptly. In this guide, we’ll discuss common heat pump issues, troubleshooting tips, and how regular maintenance is essential to keeping your system in peak condition.
Troubleshooting Heat Pump Problems
If your heat pump isn’t functioning as expected, here are some steps you can take to identify and resolve common issues:
Thermostat Accuracy
A thermostat displaying temperatures that are 2–3 degrees off can result from improper placement or calibration. Make sure the thermostat is not exposed to direct sunlight or drafts. If recalibrating doesn’t help, consider upgrading to a newer model.
Check the Air Filter
Dirty air filters restrict airflow, reducing efficiency and increasing wear on your heat pump. Replace filters every 2–3 months to maintain performance.
Inspect Power and Settings
Verify that the heat pump is powered on, the thermostat is set correctly, and no circuit breakers have tripped. A system reset—turning it off and back on—can sometimes resolve minor glitches.
Outdoor Unit Maintenance
Debris, snow, or ice buildup on the outdoor unit is common in Ottawa’s winters. Regularly clear away snow and ice to ensure proper operation.
Blocked Vents or Registers
Ensure all vents and registers are open and unobstructed. Restricted airflow can lead to uneven heating or cooling throughout your home.
If troubleshooting doesn’t resolve the issue, consider requesting professional service from AirZone HVAC Services through our Request Service page.
Common Heat Pump Issues in Ottawa
Ottawa’s climate can create unique challenges for heat pump performance. Some of the most frequent issues include:
Frozen Outdoor Coils
Harsh winters can lead to frost accumulation on outdoor coils. Heat pumps are designed to defrost automatically, but excessive ice may require manual defrosting or professional attention.
Thermostat Problems
Issues like inaccurate readings or malfunctioning displays can disrupt your comfort. Ensure your thermostat is calibrated or upgrade to a smart thermostat for improved accuracy.
Reduced Efficiency in Extreme Cold
Heat pumps are highly efficient but may struggle during the coldest days. Consider using a supplemental heating source, such as a furnace, during extreme weather.
Unusual Noises
Rattling, squealing, or humming sounds can indicate loose components, motor issues, or airflow restrictions. Addressing these promptly can prevent more significant damage.
