This is why you need to check your filters monthly and clean or replace them, depending on use and air quality. Changing or cleaning your filters is one of the most effective DIY heat pump maintenance steps you can take to improve efficiency and indoor air quality.
Keep the Outdoor Unit Clean and Clear
Your heat pump’s outdoor unit is exposed to dirt, leaves, grass, and even snow. Debris buildup blocks airflow, reducing system efficiency and increasing wear and tear. Regularly inspect and clear debris around the unit.
Ensure you maintain at least 2 feet of clearance on all sides. In winter, safely remove snow buildup to prevent damage and maintain performance. Additionally, don’t place the unit under leaking gutters or near heavy foliage.
Schedule Annual Professional Maintenance
While many tasks can be done yourself, professional maintenance twice a year – once before the heating season and once before the cooling season – is important. A qualified HVAC technician will:
- Lubricate moving parts to reduce wear
- Check refrigerant levels and top up if necessary
- Ensure proper airflow and ductwork efficiency
- Inspect and clean evaporator and condenser coils
- Test electrical components and thermostat settings
Professional tune-ups help catch hidden issues early, ensuring your heat pump runs smoothly. It also complies with warranty requirements.
Optimize Thermostat Settings
Avoid frequent thermostat adjustments. They cause your heat pump to work harder and waste energy. Set your thermostat to a steady, comfortable temperature and leave it there. For example:
- In summer, set it to 78°F when home and higher when away
- In winter, keep it around 68°F when home and lower when sleeping
Consider installing a programmable or smart thermostat designed for heat pumps to maintain optimal temperatures efficiently.
Check for Unusual Noises or Vibrations
Strange sounds can be a sign of trouble. Here’s a breakdown of unusual heat pump noises and what they may mean:
- Hissing: This may mean a refrigerant leak
- Screeching: Often suggests a failing motor or fan belt
- Clicking: Maybe a sign of a failing relay or thermostat issue
- Grinding: Can suggest a motor problem, possibly worn bearings
- Banging: This can indicate loose components, such as a fan blade hitting the housing

Early detection prevents costly repairs or system failure. If you hear unusual noises, schedule a professional inspection promptly.
Maintain Proper Airflow Inside Your Home
Blocked or closed vents reduce airflow, forcing your heat pump to work harder. Keep furniture, curtains, and rugs away from supply and return vents.
Regularly dust and vacuum around vents to prevent dust buildup. For ducted systems, schedule duct cleaning every few years. It will help maintain airflow and efficiency.
Inspect and Clean Heat Pump Coils
Dirty coils reduce heat transfer efficiency, increasing energy consumption. Clean both the evaporator and condenser coils frequently. Use a soft brush or garden hose at low pressure to remove dirt and debris.
If you notice persistent ice buildup on coils, contact a professional technician since it may be a sign of refrigerant or defrost system issues.
Avoid Setting Back Thermostat Too Much in Winter
Setting the thermostat back too far can cause the heat pump’s backup electric heater to kick in. This is often less efficient and more expensive to run. Reduce setbacks to twice a day to save energy without triggering backup heat.
