About our air conditioning repair in Cotman's Ash
Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. Common call-outs are for a unit that won’t start and a suspected refrigerant leak, on ceiling cassettes, ducted systems and wall-mounted split systems.
We plan the trip to Cotman's Ash so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Rural lanes and tight entrances are worth mentioning before a visit to Cotman's Ash.

Cotman's Ash: your questions answered
Do you cover smaller places like Cotman's Ash?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Who do I call if my air conditioning fails in Cotman's Ash out of hours?
The emergency line is open around the clock, and Cotman's Ash is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
What causes ice on the indoor coil?
Ice is a symptom of low airflow or low refrigerant. A clogged filter, a fan problem or a leak are typical. Turn it off, let the ice melt and give us a ring on 07833 053749 or drop us a line.
How much is an air conditioning call-out?
It starts with a diagnosis call-out from £75 + VAT, followed by a fixed price for the repair. Nothing goes ahead without your agreement.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
How long will you be on site?
That depends on what’s involved, but as a guide it takes a single visit for many faults, while some repairs need a second visit once parts arrive. We will confirm it with the quote.
My system uses R410A. Can it still be repaired?
Yes. Any leak is repaired before recharging, and the work is recorded and we’ll give you an honest view on whether it’s worth it.
Managing agents and facilities teams in Cotman's Ash
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements, and we’ll send a fixed-price quote.
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
A customer’s words
“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.”
