Heat pump servicing in Great Dunmow: what to expect
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
Service visits in Great Dunmow include unvented cylinder safety checks alongside the heat pump itself. Heat pumps in Great Dunmow that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Homes where running costs have crept up or rooms feel cooler than before
- Systems where the manufacturer's warranty requires annual servicing
- Landlords who need dated service records for each property
What's included
- Glycol or antifreeze protection test where fitted
- A dated service record for your warranty and property files

- Unvented cylinder safety checks and legionella cycle check

If a heat pump in Great Dunmow has not been serviced for a while, the first visit includes a full check of settings and pressures.

Heat pump servicing in Great Dunmow: questions
How much does a visit cost in Great Dunmow?

How much does a heat pump service cost?
An annual heat pump service has a guide price of £120–£250, including VAT. Where your price sits depends on the type of system, whether it is a split system needing refrigerant checks and whether an unvented cylinder is included. Any parts or repairs found during the service are explained and priced before any work goes ahead.
What does a heat pump service not include?
A service covers inspection, cleaning, testing and adjustment. It does not include replacement parts, major repairs, system flushing or radiator changes, which are quoted separately if needed. If the engineer finds a fault, they explain what it is, what it would cost to fix and whether it needs doing now or can wait.
