Common Heat Pump Problems We Solve

Our experienced technicians have seen it all. We arrive equipped to handle a wide range of heat pump issues, from minor glitches to major component failures. We are your local solution for diagnosing and fixing the problems that commonly affect Herculaneum homes.

Heat Pump Blowing Cold Air in Heat Mode

This is one of the most frustrating heat pump issues. While your system might be running through a normal defrost cycle, persistent cold air often points to a deeper problem. Common causes include a malfunctioning reversing valve, low refrigerant levels, or a compressor issue. Our technicians can quickly identify the source and perform the necessary repairs to get warm air flowing again.

Unit Is Not Heating or Cooling Correctly

If your heat pump is running but fails to reach your desired temperature, it’s a clear sign of inefficiency. This could be caused by something as simple as a clogged air filter restricting airflow or a more complex problem like a faulty thermostat, a refrigerant leak, or failing capacitors. We conduct a full system diagnostic to pinpoint the exact reason for the poor performance.

Strange or Loud Noises

Your heat pump should operate with a consistent, low hum. If you start hearing unusual noises, it’s your system’s way of signaling a problem.

• Grinding or Squealing: Often indicates a problem with the motor bearings.
• Hissing: Can be a sign of a refrigerant leak.
• Clanking or Banging: May suggest a loose component or a serious compressor issue. Ignoring these sounds can lead to more extensive and costly damage.

Frozen Outdoor Coils

During cold Herculaneum winters, it’s normal for a light layer of frost to form on the outdoor unit, which the system’s defrost cycle should handle. However, if the entire unit becomes encased in ice, it points to a malfunction. This could be due to a faulty defrost control board, low refrigerant, or restricted airflow from dirty coils or a failing fan motor.

Constant Running or Short-Cycling

A heat pump that runs constantly or turns on and off every few minutes is not operating efficiently. Short-cycling can be caused by an oversized system, thermostat miscalibration, or blocked airflow. A system that never shuts off may be struggling with low refrigerant or a failing compressor. Both issues lead to excessive wear and tear and significantly higher energy bills.

Unexpected Spike in Energy Bills

If your utility costs have suddenly increased without a change in usage, your heat pump’s efficiency may have declined. Worn-out components, dirty coils, or refrigerant leaks force the system to work much harder to heat or cool your home. Our repair service focuses on restoring this efficiency to help you manage energy costs.

Simple Troubleshooting Checks Before You Call

Sometimes, a heat pump issue has a simple fix. Before scheduling a service call, you may want to perform these quick checks to potentially save time and money.

• Check Your Thermostat: Ensure it is set to "Heat" or "Cool" and that the temperature is set correctly. A dead battery can also cause issues, so try replacing them if your thermostat is battery-powered.
• Inspect the Air Filter: A dirty or clogged air filter is a leading cause of poor airflow and system inefficiency. Check your filter and replace it if it appears dirty.
• Reset the Circuit Breaker: Locate your electrical panel and find the breaker for your heat pump. If it has tripped, switch it fully off and then back on. If it trips again, do not reset it and call us immediately, as this indicates an electrical problem.
• Clear the Outdoor Unit: Make sure the outdoor unit is free of leaves, snow, dirt, and other debris. At least two feet of clearance is needed around the unit for proper airflow.

If these steps don’t resolve the issue, it’s time to call in a professional. Continuing to operate a malfunctioning system can cause further damage.
