If you neglect to have your heat pump serviced by a professional, you may void your warranty, leaving you responsible for any repair or replacement costs. Therefore, it’s essential to keep a record of your maintenance visits to demonstrate that you’ve complied with the warranty requirements.

Conduct Regular DIY Maintenance

Homeowners can take steps to keep their units running smoothly. This can include professional maintenance, but there are also things they can do on their own. Here are some tips for conducting regular DIY maintenance:

DIY Heat Pump Maintenance

Clean or replace air filters: The air filters in your heat pump can become clogged with dust and dirt over time, which can make the system work harder and less efficiently. It’s important to clean or replace the air filters on a regular basis, which can be as often as once a month during periods of heavy use.

Clear debris from outdoor unit: If you have an air-source heat pump with an outdoor unit, it’s important to regularly clear away any debris that may have accumulated around the unit, such as leaves, grass, and dirt. This will help ensure that the unit is able to draw in air effectively and operate at peak efficiency.

Check for refrigerant leaks: Low refrigerant levels can cause your heat pump to work harder and less efficiently, leading to higher energy bills and potentially costly repairs. You can check for refrigerant leaks by inspecting the refrigerant lines and looking for signs of oil or moisture.

Keep the area around the indoor unit clean: The indoor unit of your heat pump can also become clogged with dust and dirt, which can reduce efficiency and even damage the system over time. To keep the indoor unit working properly, it’s important to keep the area around it clean and clear of debris.

By following these simple heat pump maintenance tips, you can help ensure that your heat pump is running efficiently and effectively, which can save you money on your energy bills and prevent costly repairs down the line.

Keep the Outdoor Unit Clear of Debris

A heat pump’s outdoor unit is responsible for exchanging heat between the refrigerant and the outdoor air. However, debris such as leaves, dirt, and other materials can accumulate around the unit and negatively impact its performance. In order to ensure optimal efficiency, it’s important to keep the outdoor unit clear of debris.

Debris around the outdoor unit can restrict airflow, which can cause the heat pump to work harder than necessary. This can result in increased energy consumption, higher utility bills, and even premature wear and tear on the unit. In addition, debris can also damage the unit’s coils and fins, which can further impact its performance and efficiency.

To keep the outdoor unit clear of debris, homeowners should regularly inspect the area around the unit and remove any debris that has accumulated. This can include raking up leaves, sweeping away dirt and debris, and trimming back any overgrown vegetation.

Homeowners should also make sure that the area around the unit is free of clutter, such as garden hoses or tools, that could obstruct airflow or cause damage to the unit.

Monitor and Maintain Proper Refrigerant Levels

Maintain proper refrigerant levels

Heat pumps rely on refrigerant to transfer heat between the indoor and outdoor units. The refrigerant is responsible for absorbing heat from the air outside and releasing it into the air inside. Therefore, proper refrigerant levels are essential to the efficient operation of a heat pump.

If a heat pump has low refrigerant levels, it will have to work harder to transfer heat, reducing its efficiency and potentially causing damage to the compressor. Signs of low refrigerant levels include reduced heating or cooling performance and unusual sounds coming from the unit.

To monitor and maintain refrigerant levels, it’s important to have a professional technician perform regular maintenance checks. During these checks, the technician will check the refrigerant levels and add more if necessary. It’s also important to ensure that the system is not leaking refrigerant, as this can cause a drop in levels and reduce efficiency. Regular maintenance checks can help identify and fix any leaks before they cause further damage.

It’s important not to attempt to add refrigerant yourself, as doing so can cause damage to the system and potentially harm your health.

Check and Clean Coils

Heat pump coils play a vital role in heat transfer and overall efficiency. The evaporator coil inside the indoor unit extracts heat from the air inside your home, while the condenser coil in the outdoor unit releases that heat into the air outside. Dirty coils can negatively impact heat pump performance by reducing the heat transfer efficiency, leading to higher energy bills and system wear and tear.

To maintain optimal heat pump performance, it is important to check and clean your coils regularly. Start by turning off the power to the unit and removing any covers or panels. Check the coils for visible signs of dirt or debris, such as dust, pollen, or grass clippings. Use a soft brush or cloth to gently clean the coils, taking care not to bend or damage them.

For more thorough cleaning, a coil cleaner specifically designed for heat pumps can be used. Follow the manufacturer’s instructions carefully and wear protective gloves and eyewear. Rinse the coils thoroughly with water to remove any cleaning solution residue.

It is important to note that cleaning the coils is a delicate process and should only be done by a professional if you are not comfortable with the task. A professional technician can also perform a more thorough cleaning by using specialized tools and equipment.

Regular coil cleaning can help extend the life of your heat pump and improve its efficiency. Set a goal to clean your coils yearly. If you live in a dusty or high-pollen area, clean them more often. By keeping your indoor and outdoor coils clean, you can help ensure that your heat pump is operating at its best and avoid costly repairs.

Check Thermostat and Controls

The thermostat and controls of a heat pump are essential components that help maintain the desired temperature in your home. They regulate the heat pump’s operation, controlling the heating and cooling cycles to ensure optimal performance and energy efficiency. A malfunctioning thermostat or control can lead to increased energy consumption, discomfort, and even equipment failure. Therefore, it is essential to ensure that these components are working correctly.

Have you been having trouble with your thermostat or controls? If so, it is best to consult a professional HVAC technician. They can accurately diagnose and repair the issue.


In conclusion, maintaining your heat pump is crucial for optimal efficiency and longevity. Regular professional maintenance is essential for keeping your heat pump running smoothly.
