Air Conditioning Repair in Cumnor
We cover Cumnor for air conditioning repair. Diagnosis first, a fixed price and proper paperwork when we finish.
- A unit that won’t start
- Rattling, buzzing or grinding noises
- A fault code on the display
Honest limits
To be straight with you, there are a few things this work won’t fix:
- An old system with obsolete parts
- A building problem rather than a system fault
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
If you’re not sure, just ring us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll give you a straight answer.

About our air conditioning repair in Cumnor
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, so we diagnose before we repair. If the problem is a suspected refrigerant leak and an error code or flashing light on the unit, we can help.
A visit to Cumnor is planned so we can typically finish in one go, unless a part has to come from the manufacturer.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

How we price air conditioning repair
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The brand, model and parts involved
- The distance and route between the indoor and outdoor units
- The size of the job
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before any work starts, with VAT shown clearly.
What to send for a quote
To help us quote quickly, send us:
- Any previous service or F-Gas records
- Your consumer unit or fuse board
- The remote or wall controller showing any error
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
System by system
Condensate drains and pumps
Most water leaks from indoor units come back to the condensate system. Blockages, kinks and failed pumps are the usual causes, and a unit that isn’t level can spill water too.
Wall-mounted split systems
Wall-mounted splits are the systems we repair most often. Drains, coils, fans, sensors and leaks account for many of the faults, and most are diagnosed on the first visit.
Air conditioning repair in Cumnor: the local picture
The 2021 Census found about 80% of households in detached or semi-detached houses. If the outdoor unit is high up or behind a locked gate, mention it when you book. The Cumnor Conservation Area is within about a third of a mile of the centre of Cumnor. About 30 listed entries lie within half a mile of central Cumnor, Church of St Michael (grade I) among them. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
Schools such as Cumnor Church of England School (Voluntary Controlled) can report a fault on the 24/7 line and have non-urgent work done out of term. If the display shows a code, write it down: it helps narrow down the fault.

- The engineer diagnoses the fault on site, testing rather than guessing.
- You get the cause explained and a fixed price for the repair.
- Once agreed, the repair goes ahead.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
