Signs Your Heat Pump Needs Professional Repair
Sometimes, a heat pump will fail completely without warning. More often, however, it will display signs of distress long before it shuts down. Recognizing these symptoms early can help you avoid a complete system breakdown and potentially more expensive repairs. If you notice any of the following issues with your Plymouth home's heat pump, it’s time to call for a professional inspection.
Insufficient Heating or Cooling
One of the most obvious signs of a problem is when your heat pump simply isn't doing its job. If the air coming from your vents is lukewarm in heating mode or not cool enough in cooling mode, it could indicate several issues. Common culprits include low refrigerant levels, a malfunctioning reversing valve, or a problem with the compressor. Ignoring this can lead to the system working harder than necessary, driving up energy bills and causing further strain.

The System is Constantly Running
A heat pump should cycle on and off to maintain your desired temperature. If you notice your unit is running continuously without reaching the thermostat setting, it's a clear red flag. This could be caused by an undersized unit, a refrigerant leak, or failing components. Continuous operation is not only inefficient but also puts immense wear and tear on the system, shortening its lifespan.
Strange or Loud Noises
Your heat pump should operate with a relatively low hum. Any new or unusual sounds warrant immediate attention.
- Grinding or Scraping: This often points to a serious issue with the motor bearings or other moving parts. Shut the system down immediately to prevent catastrophic failure.
- Squealing or Hissing: A high-pitched squeal may indicate a problem with the blower motor or belt, while a hissing sound can be a sign of a significant refrigerant leak.
- Banging or Clanking: These sounds could mean a component has come loose, such as a fan blade or a piece of the motor mount.
Ice Buildup on the Coils
While a light layer of frost on the outdoor unit during winter is normal and should be handled by the defrost cycle, a thick buildup of ice is not. Ice on the coils, either indoors or outdoors, restricts airflow and severely hampers the heat transfer process. This can be caused by dirty filters, a low refrigerant charge, or a malfunctioning defrost control board.
Sudden Spikes in Your Energy Bills
A heat pump is valued for its energy efficiency. If you see a sudden and unexplained increase in your utility bills, your heat pump’s performance may be to blame. A struggling system consumes more electricity to produce the same amount of heating or cooling. This inefficiency can stem from a wide range of issues, from dirty coils to a failing compressor.
