Common Heat Pump Problems We Solve

Heat pumps are complex systems, and when they break down, the symptoms can be confusing. Our experienced technicians at Southern Air have seen it all and arrive equipped to identify the root cause of your problem and implement a lasting solution. We frequently handle the following issues for homeowners throughout Winchester:

Heat Pump Not Heating or Blowing Cold Air

One of the most frustrating problems, especially during winter, is when your system blows cool or lukewarm air instead of heating. This can be caused by low refrigerant levels, a malfunctioning reversing valve, or compressor issues. Our technicians use precise diagnostic tools to test refrigerant pressures and inspect key components to find the exact cause.

Heat Pump Not Cooling Effectively

In the summer, a lack of cooling is often tied to refrigerant leaks, dirty air filters restricting airflow, or failing compressors. Sometimes, a blocked condenser coil in the outdoor unit prevents heat from being released effectively. We perform a comprehensive inspection to ensure every part of the cooling cycle works correctly.

Strange or Loud Noises

Your heat pump should operate with a consistent, low-level hum. Any new or unusual noises signal trouble:

1. Grinding or Scraping: Often due to failing motor bearings or compressor issues—turn off your system immediately to avoid further damage.
2. Squealing: Indicates a worn-out fan belt or a motor needing lubrication.
3. Gurgling or Bubbling: Usually caused by low refrigerant charge or leaks in the refrigerant lines.
4. Clanking or Banging: Typically a loose part, such as a fan blade or internal hardware.

System Constantly Running or Short-Cycling

A heat pump that runs non-stop or turns on and off frequently wastes energy and fails to regulate temperature properly. Causes range from clogged filters and faulty thermostats to refrigerant leaks or incorrectly sized units.

Outdoor Unit Frozen or Iced Over

While light frost in winter is normal, thick ice indicates a problem—often due to a malfunctioning defrost control board, faulty sensors, or low refrigerant. These issues prevent the system from clearing ice as intended.

Should You Repair or Replace Your Heat Pump?

Winchester homeowners often face the decision of whether to repair or replace a heat pump. At Southern Air, we give honest recommendations based on:

1. Age of the System: Units over 10–15 years old may not be worth major repairs.
2. Cost of the Repair: If repair costs approach 50% of a new system, replacement is the smarter choice.
3. Frequency of Breakdowns: Constant repairs can make upgrading to a new, efficient unit more economical.

We provide a clear system health assessment to help you make the best choice for your comfort and budget.
