Carrier Heat Pump Maintenance
Keeping indoor temperatures consistent and at the right set point can bring comfort to any space. Maintaining equipment is the key to ensuring that equipment can stay efficient and provide constant temperature control. Heat pumps are a part of the HVAC systems that provide this control, so learn more about Carrier heat pump maintenance below.

Service Checklist
Routine maintenance service calls are an important part of helping stay on top of appliance care. These professionals can help check more technical parts of the unit so you can rest assured with their thorough checks. Some things they might include are:
- Checking refrigerant levels
- Checking for leaks
- Making sure airflow is moving
- Checking all electrical connections are secure
- Checking physical connections of parts
- Checking the run capacitor for bulging, unusual markings or color
- Check and clean the outdoor unit and coils
- Inspecting the reversing valve
- Testing the defrost cycle
- Checking the auxiliary heating system
- Testing for heating in defrost mode
- Checking and cleaning the indoor coils
- Checking and cleaning the condensate drainage system
- Cleaning and adjusting blower components
- Checking and cleaning the air filter
Heat Pump Maintenance
Filter Maintenance
Keeping filters free of build-up from debris is an essential maintenance step. A clogged filter will cause the unit to strain during operation, increasing costs and shortening the lifespan of the unit. Make sure filters are clean and installed correctly for the best outcome of your heat pump.
Keep Vents Clear
Check that all vents are clear from obstructions and that proper airflow isn’t being restricted. Larger furniture or appliances should be spaced far enough away and smaller objects away from ventilation. Blocked vents only put strain on the unit and can reduce efficiency and the equipment’s lifespan. Also check that coils are free of debris or build-up.
Maintain Outdoor Unit Areas
Maining outdoor equipment can be just as crucial as cleaning the indoor units. Make sure any outdoor components have unrestricted airflow. Check for leaves and debris that can accumulate and remove these frequently, so the unit can run at peak performance. Outdoor equipment also needs to have space and clearance from other objects, so check that it is located in an open space.
Check Drains & Pans
Frequently checking and dumping any drainage or pans can help to keep units working and prevent leakage. Condensate pans and base pans need to be checked routinely to ensure that they are clogged and are draining water.
Operating Temperatures
Outdoor units are not meant to be operated in extreme temperatures, as this can cause breakdowns and malfunctions. When the outdoor temperature is below 10ºF (-12ºC), the
unit control may automatically shut the heat pump off and energize auxiliary heat to maintain the desired temperature set point inside. The minimum temperature for operating in cooling mode is 40ºF (4ºC) for the Infinity Touch Control and 55ºF (13ºC) for thermostat controls. The maximum temperature that the outdoor unit can safely operate in heating mode is 66ºF (19ºC).
