About our air conditioning repair in Ayot St Peter
We repair air conditioning on all the main brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Systems fitted by other installers are fine too and the make and model help us prepare. Common call-outs are for a system that runs but doesn’t cool the room and a unit that won’t start, on ceiling cassettes, multi-split systems and heat pumps.
Around Ayot St Peter, outdoor units often sit close to gardens and hedges, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Ayot St Peter questions
Is there an emergency air con repair line for Ayot St Peter?
The emergency line is open around the clock, and Ayot St Peter is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you cover smaller places like Ayot St Peter?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
My air con is showing an error code. What should I do?
An error code points us in the right direction, but it is not the whole answer. Write down the code and turn the unit off if it has stopped, and phone us on 07833 053749 or send an email.
Can you repair an R22 air conditioning system?
In most cases, we recommend replacement. R22 can’t be topped up with new gas, and parts for old models are scarce, so we will quote for a modern replacement and explain why.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book, and we are happy to show ours.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
How the visit works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Photos of the existing unit help with repairs and servicing in Ayot St Peter.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Prescribe: tell you the cause and the fixed cost of the cure.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
Getting ready for the visit
- Mention any roof access, ladders or high-level work
- Clear a path to the units and the space around them
- Keep pets out of the rooms we are working in

Fans and compressors
At the centre of the system is the compressor. Compressor faults can sometimes be caused by something else, such as an electrical fault or a refrigerant problem, so we test before condemning it. A failed compressor often raises the repair-or-replace question, and we give you both prices.
Wall-mounted split systems
The indoor and outdoor units of a split communicate through a cable. A break in that communication normally brings up an error code and testing finds whether it’s the cable, a board or a connection.
When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- An R22 system that has lost its refrigerant
- A discontinued model with no parts available
- Heat gains the system was never designed for
If you’re not sure, just ring 07833 053749 and we will give you a straight answer before you book.

“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.”
