Common Heat Pump Problems We Solve
Heat pumps are sophisticated systems that work hard throughout the year. Due to this constant operation, they can develop a range of issues. Our experienced technicians have seen it all and are equipped to handle any problem your system might face. If you notice any of the following signs, it’s time to schedule a professional inspection.

Heat Pump Is Not Turning On
The most alarming issue is when the system fails to start. This could be caused by something as simple as a tripped circuit breaker or a miscalibrated thermostat. However, it can also point to more serious problems like a faulty capacitor, a wiring issue, or a failed compressor. Our technicians will safely and accurately diagnose the electrical components to find the root cause.
Blowing Cold Air in Heat Mode (or Warm Air in Cool Mode)
If your heat pump is running but not delivering the right temperature air, the reversing valve is often the primary suspect. This critical component is responsible for switching the flow of refrigerant between heating and cooling modes. A stuck or broken reversing valve will leave your system stuck in one mode, unable to provide the comfort you need. Other potential causes include low refrigerant levels or an issue with the outdoor unit.
Constant Cycling or Running Continuously
A heat pump that turns on and off too frequently (short cycling) or one that never seems to shut off is a clear sign of inefficiency. This could be due to a clogged air filter restricting airflow, a refrigerant leak, an incorrectly sized unit for your home, or a faulty thermostat. This constant operation not only fails to heat or cool your home effectively but also drives up your energy bills and puts excessive strain on the system's components.
Unusual Noises During Operation
Your heat pump should operate with a relatively low hum. If you start hearing loud, unusual noises, it’s a warning sign that a component is failing.
- Grinding or Squealing: This often indicates worn-out motor bearings in the indoor or outdoor unit.
- Rattling or Banging: This could be caused by loose parts, such as a panel, screws, or debris in the outdoor unit.
- Hissing or Bubbling: These sounds almost always point to a refrigerant leak, which is a serious issue that needs immediate attention.
The Outdoor Unit Is Icing Over
It is normal for a light layer of frost to form on the outdoor coil during the winter. However, your heat pump should automatically run a defrost cycle to melt it. If a thick layer of ice builds up and doesn't go away, it signals a problem with the defrost control board, a faulty sensor, or low refrigerant levels. An iced-over unit cannot transfer heat effectively, drastically reducing its efficiency and potentially damaging the compressor.
Our Comprehensive Heat Pump Diagnostic and Repair Process
We believe in a transparent and thorough approach to every repair. Our goal is not just to fix the immediate problem but to ensure your entire system is functioning safely and efficiently.
- Thorough System Evaluation: Our process begins with a complete diagnostic inspection. A technician will meticulously examine both the indoor and outdoor units. This includes checking refrigerant pressure, inspecting electrical connections, testing capacitors and contactors, cleaning coils if necessary, examining the thermostat's calibration, and listening for any abnormal sounds.
- Clear Diagnosis and Honest Recommendations: Once we have identified the source of the problem, we will explain the issue to you in clear, easy-to-understand terms. We will outline the necessary repairs, discuss your options, and provide a complete breakdown of the work required. We don’t proceed with any repairs until you fully understand the solution and have given your approval.

Whether it involves fixing a refrigerant leak, replacing a faulty motor, or repairing the reversing valve, we adhere to the highest industry standards to ensure a lasting solution. We have experience servicing all major brands and models of heat pumps.
- Final System Testing and Verification: After the repair is complete, we don’t just pack up and leave. We turn the system on and run it through a full cycle to verify that it is operating correctly, safely, and efficiently. We measure temperature output and airflow to confirm that your home’s comfort has been fully restored.
