Air Source Heat Pump Servicing: Here’s What You Need To Know

Heat pumps are a robust and reliable heating source, and compared to other more traditional heating methods, can also be cost effective and good for your carbon footprint.
What is an air source heat pump?
An air source heat pump works similarly to an air conditioning system, but is a renewable technology which uses outside air to heat a property and can also heat your water supply. Even in cold external temperatures, a heat pump can replace stale, warm internal air and convert it into fresh incoming heated air, all using an efficient form of energy.
Air source heat pumps are expected to last between 20 to 30 years and require relatively little maintenance. Generally speaking you should also avoid having to replace expensive parts, in comparison to other forms of heating. However, this maintenance is very important to the long term health and efficiency of its operation.
Regular inspection and maintenance of your heat pump
Your air source heat pump unit requires the following regular inspection and maintenance:
- Filters should be cleaned and or swapped out
- Coils and fans should be cleaned if necessary
- Clear the unit of debris such as leaves and dust etc, as it can impede airflow and therefore require the system to use more energy to operate
- Supply and return registers inside the property should be cleaned
- With the power off to the unit, the fan blades should be checked and cleaned.
Annual service of your air source heat pump
On an annual basis your unit will require a thorough stripping down and a more advanced audit and replacement of the internal components. This will pre-empt any routine problems, but will also ensure that the unit runs at optimum efficiency, as well as prolonging the lifespan of the unit. It would make sense to carry out this service in the approach to the winter months, when the unit is expected to work hardest and its ongoing performance is more critical.
The annual checks included in a service should include:
- Ducts should be checked for leakage and repair where necessary
- Filters, ducts, blower and indoor coil should be inspected for dirt and other obstructions building up and impeding airflow
- You should measure that the current airflow is correct
- Refrigerant levels and pressure should be checked
- All electrical contacts should be inspected to ensure they are protected from the elements
- The entire system should be checked for leaks
- Reverse heating/cooling controls should be checked to verify they are operating as required
- Moving belts and motors should be lubricated and checked for damage and wear and tear
- Thermostat should be checked and tested under normal operating conditions.
