Common Problems with Residential Heat Pumps & How to Repair Them

Before calling a professional for heat pump repair, there are several DIY heat pump troubleshooting steps you can take to identify and possibly resolve common issues. 

Thermostat Isn't Working Properly

Start by checking the thermostat settings. Ensure it’s set to the correct mode (heating or cooling) and the temperature is adjusted properly. If the thermostat isn’t working, replace the batteries.

Heat Pump is Frozen

A frozen heat pump may be caused by restricted airflow, low refrigerant levels, or a malfunctioning defrost cycle. Check for blocked air vents, dirty filters, or ice buildup on the outdoor unit. If the unit remains frozen after cleaning and restarting, it's best to call your local Carrier dealer to inspect the refrigerant levels and defrost components.

Heat Pump Isn't Blowing Enough Air

If your heat pump isn’t blowing enough air, it could be due to a clogged filter, blocked ductwork, or a failing blower motor. Start by checking and replacing the air filter if needed, then inspect vents and registers for obstructions. If the airflow issue persists, your local Carrier dealer should inspect the system for mechanical problems.

Heat Pump Won't Turn Off

If your heat pump isn’t blowing enough air, it could be due to a clogged filter, blocked ductwork, or a failing blower motor. Start by checking and replacing the air filter if needed, then inspect vents and registers for obstructions. If the airflow issue persists, your local Carrier dealer should inspect the system for mechanical problems.

Heat Pump is Blowing Cold Air in Heat Mode

If your heat pump is blowing cold air while in heat mode, it may be in defrost mode, have a malfunctioning reversing valve, or low refrigerant. Check if the unit switches back to warm air after a few minutes—if not, further diagnosis is needed. Visit our Heat Pump Not Heating page for more troubleshooting tips and solutions.

Step-By-Step Process for Heat Pump Repairs

Step 1: Initial Heat Pump Assessment

Your HVAC contractor will first ask you to describe the issue and any symptoms you've noticed with your heat pump. The technician will perform a visual inspection of the heat pump, checking for obvious signs of damage, wear, or malfunction.

Step 2: Heat Pump Diagnostic Testing

HVAC contractor will then perform a series of diagnostic tests on your heat pump to check for the specific issues leading to the need for a heat pump repair.

• Electrical Tests: The technician will check the electrical components, including the thermostat, wiring, capacitors, and contactors, to ensure they are functioning correctly.
• Refrigerant Levels: The refrigerant line will be checked to ensure the levels are within the proper range. Low refrigerant can indicate a leak that needs to be repaired.
• Airflow Check: The technician will inspect the airflow, including the condition of the air filters, blower motor, and ductwork, to ensure there are no obstructions or issues.
• Operational Tests: The heat pump will be run through its heating and cooling cycles to observe any performance issues and listen for unusual noises.

Step 3: Identifying The Heat Pump Problem

Your HVAC contractor will test individual components like the compressor, reversing valve, and sensors, analyzing the results to pinpoint the root cause of the problem.

Step 4: Heat Pump Repair Solutions

If any components like capacitors, fan motors, thermostats, or the reversing valve are faulty, they will be replaced, while refrigerant leaks will be repaired and recharged, and the technician will clean coils, filters, and perform routine maintenance to ensure optimal system performance

Step 5: Heat Pump System Testing

After the heat pump repairs are completed, the technician will test the system to ensure it is operating correctly and efficiently. Safety features and controls will be checked to ensure they are functioning properly.

Step 6: Final Steps and Follow-Up

The technician will explain the repairs made, provide maintenance instructions, document all work and parts used, and may schedule a follow-up visit to ensure the system is functioning properly.
