Common Questions about ASHP Servicing
-
We recommend servicing your air source heat pump at least once a year. Regular servicing ensures your system runs efficiently, prevents costly breakdowns, and maintains manufacturer warranties. During a service, we check system performance, clean key components, top up glycol if needed, and spot any potential issues early, helping your heat pump last longer and reduce energy bills.
-
A comprehensive service includes:
Inspecting and cleaning the external unit, fan, and heat exchanger
Checking refrigerant levels and pressure
Testing system controls and thermostats
Inspecting all electrical connections for safety
Checking the circulation pump, valves, and expansion vessel
Assessing system efficiency and performance
Identifying any leaks or corrosion
Advising on any necessary upgrades or adjustments
-
No. Air source heat pump systems are complex and contain pressurized refrigerants. Servicing must be carried out by MCS-certified engineers like Russell Haskins to ensure safety, efficiency, and compliance with manufacturer requirements. Attempting to service your unit yourself could void the warranty or cause damage.
-
An air source heat pump service takes approximately one hour, depending on the system’s complexity, the number of zones, and any additional components such as underfloor heating or large cylinders. During the service, we also provide advice on maintaining efficiency and longevity of your heating system.
-
Yes. Over time, dirt, debris, and minor wear and tear can reduce efficiency of your air source heat pump. Regular servicing of your unit and heating system ensures your air source heat pump is running optimally, maintaining its high coefficient of performance (COP) and helping you save on electricity costs while keeping your home comfortably warm.
-
During your service, we check refrigerant levels, which is called Glycol. Top-ups are only needed if a leak or abnormal loss is detected and are not included in the standard service, and will require a separate visit. Refrigerant should not be added casually, as it is a controlled substance and requires a certified engineer to handle safely.
-
Yes. Most manufacturers require annual servicing by an MCS-certified engineer to maintain the warranty. Missing a service can invalidate your coverage, leaving you liable for repair or replacement costs that would otherwise have been protected.
-
Yes. At Russell Haskins we are MCS-certified and experienced in servicing leading air source heat pumps from different brands. This ensures your warranty remains valid and your system operates safely and efficiently.
