What moves the price
- The fault — a blocked condensate drain is a quick fix, while a refrigerant leak needs finding, sealing and regassing
- Parts — fan motors and control boards cost more than sensors and are brand-specific
- Age of the air conditioning unit — older systems may use refrigerants or parts that are hard to source
- F-gas certification — only certified engineers may handle refrigerant, which shapes who can do the repair
- Access — indoor heads high on walls and outdoor units on roofs take longer to work on
- Summer demand — air conditioning repair diaries fill fast in a heatwave
Plumbing and heating prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical air conditioning repair would have cost about £170 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Book an air conditioning service before summer, when repair diaries are quieter
- Clean or replace the indoor unit's filters yourself to avoid many weak-cooling call-outs
- Ask whether the diagnosis fee is credited against the air conditioning repair
Before you book
- Only an F-gas certified engineer can handle the refrigerant in an air conditioning system
- Ask for the fault and the repair price in writing before parts are ordered
- If the unit is old and the compressor has failed, compare the repair with a new system
- Check whether the air conditioning is still under the installer's or maker's warranty
Air Conditioning Repair cost: questions people ask
£90–£450 per job, about £180 typical. Diagnosis and a simple drain or sensor fix cost least; a leak with regas or a new control board costs the most.
Most repairs take one to two hours. Tracing a refrigerant leak or waiting for parts can mean a second visit.
Only engineers holding an F-gas certificate may handle refrigerant. Ask to see it, as it is a legal requirement.
Small faults usually are. A failed compressor on an older system often costs close to a new unit, so replacement may be better value.
A replacement unit, a new compressor on an old system and a service contract are generally separate. Ask whether parts carry a warranty.
