10 Tips For Heat Pump Maintenance for Homeowners

Heat pumps are essential equipment for any homeowner who wants to keep their home comfortable throughout the year. They help regulate indoor temperatures and make homes cool during summer and warm during winter. Like any other piece of equipment, however, they need maintenance and care to perform optimally and last long.

This blog will provide tips for heat pump maintenance that any homeowner can follow.

Tips For Heat Pump Maintenance

Change filters regularly

Heat pump filters trap dirt, dust, and other impurities, ensuring that the device produces clean air. Over time, the filters become clogged with trapped debris, making the heat pump less efficient. You should change your heat pump filters at least once a month to keep them working as they should.

Keep the outdoor unit clear

The outdoor unit of your heat pump can attract debris such as grass, leaves, and branches, which can clog the fins or the fan. Keeping the outdoor unit clear increases the airflow to the device, making it work more efficiently. You can use a broom, rake or garden hose to clear the outdoor unit.

Check the airflow regularly

Checking the airflow regularly for your heat pump maintenance is one of the important things. A restricted airflow in your heat pump can lead to breakdowns or an inefficient system. You can check the airflow by holding a tissue or light piece of paper over the air vent. If the paper falls or moves, your airflow is sufficient, if it does not, you need to have a technician fix the problem.

Keep the surrounding area clean and unobstructed

Heat pumps require ventilation to dissipate heat and work efficiently. Ensure there are no obstructions around the outdoor unit, including plants, fences, or walls. It is also crucial to ensure that the landscaping is free of debris such as dirt and dead leaves, which can hamper the venting process.

Follow a routine maintenance schedule

Regular heat pump maintenance schedules are essential to ensure that the system is working efficiently and properly. Annual inspections and cleanings can significantly lengthen the lifespan of your heat pump. You can hire a professional technician to assess and clean the unit at least once a year.

Clean the indoor unit

The indoor component of your heat pump also requires regular cleaning to function optimally. You can remove the cover and clean it with a soft, dry brush or a damp cloth. If your heat pump has a permanent filter, clean it once every six months.

Keep the condensate line clean

The condensate line helps remove moisture from your indoors. Over time, fungus, mould, or bacteria can accumulate within the line and cause blockages. It is essential to keep the condensate line clean to avoid potential clogs that can trigger a system malfunction.

Clean the evaporator coil

The evaporator coil collects moisture and dust over time, leading to clogging. Clean the coil periodically to ensure your heat pump works optimally. Use a soft, dry brush to remove the dust, and avoid using a hard brush that could damage the coil.

Test the refrigerant regularly

Low refrigerant levels can cause heat pumps to break down, and high levels can harm the device. It is essential to check the refrigerant levels regularly, and if needed, top it up. Ideally, you should hire a professional technician to perform such tests and repairs.

Observe the unit for strange noises and undesired smells

If you notice strange noises coming from the heat pump or undesirable smells emanating from the indoor vents, it could signal an underlying problem. These symptoms could point to issues like leaks in ducts, refrigerant leaks, or electrical problems. You should contact a professional technician to diagnose the issue and offer viable solutions.


As a homeowner, heat pump maintenance can help extend its lifespan and save you from costly repairs and replacements. Regular maintenance, including changing filters, keeping the outdoor and indoor units clean and unobstructed, and inspecting and testing the refrigerant can ensure your heat pump operates efficiently for its lifespan. It would be best if you also observed the unit for strange noises and smells, and contact a technician if you notice anything unusual.
