Maintenance and air source heat pump servicing should be carried out by an accredited and qualified installer.

Each manufacturer stipulates their own criteria for air source heat pump servicing, which must be met in order to carry out the service correctly. In many cases a yearly service is necessary to keep the warranty valid.

If your service is due, please contact us and we will arrange a visit.

Servicing checklist:
  • Glycol check – this is carried out with a refractometer and gives a reading of the percentage of antifreeze in the system.
  • Field settings – run through field settings to check they are all as per manufacturer’s instructions.
  • Strainer cleaning – we install micro-strainers with our heat pumps to prevent dirt entering the machine, this dirt collects in a strainer and can affect flow rates of the heat pump, it is a good idea to clean this out once or twice a year.
  • Coil cleaning
  • Safety checks on unvented cylinder
  • Immersion – check current and if it is still performing the legionella cycle.
