Why Service Your Air Source Heat Pump?
An air source heat pump can operate quietly for long periods, but that does not mean it should be left unchecked. Regular maintenance helps keep important components clean, correctly configured and operating as intended.
​
During a service, we assess the outdoor unit, airflow, system pressure, controls and relevant heating components. We also review system performance and identify anything that may require further attention.
​
Annual servicing is widely recommended as good practice, although the correct servicing interval for your system should always be checked against the manufacturer's guidance.
What's Included in Our Heat Pump Service?
Outdoor Unit Inspection
We inspect the external unit for debris, obstructions, physical damage and anything that could affect airflow or operation.
Coil Inspection & Cleaning
We check the evaporator coil for dirt and debris. Where appropriate, cleaning helps maintain effective heat transfer and airflow.
Fan Inspection
The fan and surrounding area are checked for visible damage, debris, unusual movement or other signs that may affect operation.
System Pressure Check
We check the heating circuit pressure against the system's expected operating range and look for signs of potential issues.
Controls & Temperature Review
We check relevant controls and review flow and return temperatures to assess system operation under the conditions at the time of the visit.
Performance Assessment
We review how the heat pump is operating and identify readings or conditions that may warrant further investigation.
When Should You Service Your Heat Pump?
Around Your Annual Service Date
Many manufacturers recommend annual maintenance. Always check your specific manufacturer's servicing requirements and warranty documentation.
Booking a service ahead of colder weather gives you an opportunity to have the system checked before heating demand increases.
Before Winter
When Performance Changes
If your system appears to be using more electricity, producing unusual noise or behaving differently, a service or performance assessment may help establish what has changed.
After Extended Periods of Limited Use
If the system has been unused or operating differently for an extended period, a check can help confirm that everything is functioning as expected.
If you have moved into a property with an existing heat pump and do not have a clear maintenance history, an initial assessment can provide a useful baseline.
