Heat Pump Servicing and Deep Cleaning

How often should a heat pump be serviced?

Most heat pumps should be professionally serviced every 12 to 24 months depending on usage, pets, location and indoor air quality. Homes with pets, fireplaces, high dust levels or heavy daily use will often benefit from more frequent servicing.

Common signs your heat pump may be overdue for a service include reduced airflow, musty smells, poor heating or cooling performance, increased power consumption, unusual noises or water dripping from the indoor unit.

What temperature should I set my heat pump to in winter?

For most homes, a setting of around 20–22°C provides a good balance between comfort and efficiency. Setting the temperature much higher will not heat the room significantly faster and often increases power consumption.

What temperature should I set my heat pump to in summer?

During summer, a setting of around 22–24°C is usually comfortable and energy efficient. Extremely low temperature settings can increase running costs without providing much additional comfort.

Should I leave my heat pump running all the time?

Many people were told years ago that heat pumps should be left running continuously. While modern heat pumps are very efficient, this advice does not suit every home or lifestyle.

For most households, it is usually more economical to run the heat pump when required rather than operating it 24 hours a day. If the home is empty during work hours, there is often little benefit in maintaining temperature all day. However, very well-insulated homes or properties occupied throughout the day may benefit from longer operating periods.

How often should I clean the filters?

Most manufacturers recommend cleaning indoor filters every few months depending on usage and household conditions. Dirty filters restrict airflow, reduce efficiency and can contribute to musty smells and poor performance.
