Common Heat Pump Problems We Repair

Heat pumps work year-round, so wear and tear is common without routine maintenance. Our team regularly repairs:

Heat Pump Won’t Turn On or Shuts Off Frequently

This usually indicates an electrical issue, faulty capacitor, clogged filter, or failing safety switch that prevents the system from running properly.

Weak Airflow or Poor Temperature Control

When airflow drops, the system can’t effectively heat or cool your home. This often comes from blocked filters, blower motor issues, or duct problems.

System Stuck in Heating or Cooling Mode

If your heat pump won’t switch between heating and cooling, the reversing valve may be malfunctioning or the thermostat isn’t sending the right signal.

Loud or Unusual Noises

Buzzing, grinding, rattling, or squealing noises indicate worn-out components such as motors, bearings, or fan blades that need immediate attention.

Strange or Musty Odors

Unpleasant smells often point to mold growth, electrical issues, or overheating components inside the system or ductwork.

Thermostat Malfunctions

If your thermostat isn’t responding or reading temperatures correctly, your heat pump will struggle to maintain comfort or may cycle incorrectly.

Signs You Need Heat Pump Repair

If you notice any of the following issues, it’s time to schedule a repair:

Blowing Air at the Wrong Temperature

If the system produces cool air in heat mode—or warm air in cooling mode—it’s a clear sign something’s off.

Unusual Noises or Odors

Buzzing, grinding, or odd smells often point to mechanical or electrical issues.

Rising Energy Bills

A sudden increase typically means the heat pump is working harder than it should due to a malfunction.

Constant Running or Frequent Cycling

If your system never shuts off or switches on and off repeatedly, it needs attention.

System Is 10–15+ Years Old

Older units naturally show wear and may struggle to keep up without repair.
