Heat Pump Not Performing Well? Here’s What Might Be Happening
Troubleshooting Common Heat Pump Issues (Before They Become Costly)
Is your heat pump not heating or cooling as well as it used to? Before you worry about major repairs, a few simple checks can help you identify and fix the issue quickly.
Here are some of the most common heat pump problems and how to troubleshoot them.
1. Weak Airflow? Check Your Filters
Possible Cause: A clogged air filter can block airflow, making your system work harder than necessary.
Fix: Check your filters and replace them every 1–3 months for optimal performance.
Dirty filters are the #1 reason for reduced efficiency—don’t forget to change them!
2. Heat Pump Not Heating or Cooling Properly?
Possible Cause: Your thermostat settings may not be optimized for the season.
Fix: Ensure your thermostat is set to HEAT mode in winter and COOL mode in summer—not AUTO, which can cause temperature fluctuations.
If your system is running but not reaching the right temperature, it might be low on refrigerant—call a pro for service.
3. System Running Constantly?
Possible Cause: Dirty coils, blocked vents, or an incorrectly sized unit could be making your heat pump work overtime. Fix:
✅ Check that all vents and registers are open and unblocked.
✅ Make sure the outdoor unit is free of leaves, snow, or debris.
✅ If your system is more than 10 years old, it may be time for an upgrade to a more efficient model.
A heat pump that runs non-stop could be a sign of an inefficient system—don’t ignore it!
4. Strange Noises? Don’t Ignore Them!
Whistling or Rattling? Could indicate loose parts or airflow issues.
Grinding or Buzzing? May mean a failing motor or electrical issue.
Loud Clicking? Could be a relay issue or a sign your system is struggling to start.
If you hear unusual noises, it’s best to call a professional before the problem gets worse!
