Since mini-split heat pumps provide both heating and cooling, they need maintenance twice a year. We recommend scheduling preventative maintenance in the spring and fall. A heat pump moves heat instead of generating it, but year-round use means the system can wear out quickly if potential problems aren’t addressed. Routine maintenance can avoid mini-split repair; even if you stay on top of regular visits, don’t hesitate to call your local HVAC contractor should any issues arise.

Why Biannual Heat Pump Maintenance Is Necessary
All HVAC systems require regular maintenance. Heat pumps have unique maintenance requirements because of how they operate. They can be used during every season. A mini-split heat pump is an effective heating solution in the winter. In summer, the direction of refrigerant reverses so heat is moved out of your home to cool things down. Therefore, the unit must be at peak performance and efficiency all year long.
A heat pump has maintenance requirements similar to other heating and cooling systems. But one component that’s unique to it is the reversing valve. If it breaks, your mini-split will be stuck in one mode or another, meaning you won’t be able to switch between heating and cooling. Your local HVAC contractor can inspect, repair, or replace this component to ensure you get warm air or cooling when needed.
What Happens During a Heat Pump Tune-Up?
Aside from changing the filter, which can avoid airflow and many other problems, you should leave heat pump maintenance to a professional. During an inspection and tune-up, they will:
- Look for and clean dirt and debris in the system
- Check for malfunctioning fan motors, thermostats, and other components
- Lubricate motors and other moving parts
- Measure refrigerant levels and check for leaks
- Inspect the outdoor condenser
- Inspect the indoor air handlers
- Evaluate wiring and electrical components
Are There Other Maintenance Tasks I Can Do Myself?
Keeping mini-split units clean is important and can prevent contamination. To clean the exterior of each cabinet, use a dry cloth or small vacuum to remove dirt and dust. The filter should be checked every 4 to 6 weeks. Change the filter whenever it is dirty or clogged. You can also clean dirt and dust from inside the cabinet, carefully using a small vacuum or dry cloth to clean any components you can reach.
Also, inspect the outdoor unit from time to time. Clear leaves, twigs, and debris from the outdoor condenser and trim back shrubs. Leave at least two feet of clearance on all sides to allow for proper airflow and heat transfer. If you feel comfortable, turn the power off and use a garden hose to clean off the outdoor coils.
However, a technician can do a more thorough coil cleaning. They can clean removable coils, fans, and other parts while avoiding damage. Other treatments may be used, such as applying a bacteriostat or fungistat, so the coils stay free of contamination.
When Should I Call for Mini-Split Heat Pump Maintenance?
Problems can occur even if your heat pump is well-maintained. Nonetheless, you can prevent them from getting worse by contacting Call the Whale for mid-season maintenance. You don’t have to worry about maintaining air ducts, but you should call for help if these issues occur:
- Short-Cycling: If the unit starts to shut down sooner or turn off in more frequent intervals, it will use more energy and can wear out and break down.
- Leaks: Some condensation is normal. However, if water is dripping or pooling around the unit, the condensate drain line may be blocked or broken. Meanwhile, a refrigerant leak can harm your heat pump, your health, and the environment.
- Inconsistent Temperatures: A malfunctioning thermostat or another problem with the system can cause uneven or fluctuating temperatures in your home.
- Poor Airflow: Airflow can be restricted due to a clogged filter or an issue with the blower motor, fan, or other component a professional must service.
- Noise: If your heat pump has a grinding sound, parts may need to be lubricated. Rattling can mean motor bearings and other metal parts are wearing out while clicking from the outdoor unit can indicate a fan obstruction or electrical problem. Other sounds to be concerned about include clanging, bubbling, gurgling, hissing, buzzing, or squealing.
- Odors: A buildup of moisture in the unit can allow mold to grow, which produces musty odors. Faulty electrical wiring can release a burning smell.
- Icy Coils: Mini-split coils can freeze due to poor airflow, low refrigerant, and other issues that prevent them from transferring heat to or from the surrounding air.
- Rising Energy Bills: If your monthly utility bills are higher than the same time last year, or steadily increasing, your heat pump may be overworked and need maintenance.
