Keep the outdoor unit unobstructed
Maintain the clearances required by the manufacturer and prevent vegetation, stored items or debris from restricting airflow. Do not modify or enclose the unit without appropriate advice.
Notice changes in operation
Pay attention to new noises, persistent faults, unexpected loss of heating or unusual changes in electricity use. Fault codes should be recorded rather than repeatedly reset without investigation.
Check system pressure where applicable
If the heating circuit is sealed and has a user-visible pressure indication, repeated pressure loss can indicate a system issue requiring diagnosis.
Do not fight the controls
Heat pumps often use weather compensation and longer operating periods. Frequent arbitrary adjustments can make performance harder to assess. Settings should reflect the designed control strategy.
Arrange professional servicing
The manufacturer's maintenance requirements should be followed by competent personnel. A professional service can assess areas that are not suitable for homeowner maintenance.
