Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749 or write to us at info@aircondoctor.co.uk.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
About our air conditioning servicing in Coates
Servicing doesn’t mean topping up refrigerant. The refrigerant circuit is sealed, so a system that’s short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. The work covers VRF systems, ceiling cassettes and air-to-air heat pumps, and common reasons people get in touch are a service that’s overdue and a system that struggles to cool on warm days.
We plan the trip to Coates and can service more than one unit in one visit.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

FAQs for Coates
Can you do air conditioning servicing in Coates?
Yes, Coates is within the area we cover. To start, call 07833 053749 with a few photos.
Will you come out to Coates?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Will you regas my air conditioning on a service?
A regas is a separate job, done once a leak has been found and fixed. Topping up without finding the leak means the gas escapes again, so we do not recommend it.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.

Do you need air conditioning servicing in Coates?
Condensate has to drain away from every indoor unit. Sludge and debris can block the tray, the pipe or the pump, and the water then has nowhere to go but out of the unit.
The things we’re asked about most include:
- No service record for the last year or more
- Iced-up coils or pipework
- Noisy fans or rattling from the outdoor unit
Booking before the first hot spell means the system is ready when you need it.
What your quote should include
- Whether a new circuit is included and who certifies it
- How extra work would be agreed if they find something unexpected
- What the manufacturer’s warranty covers and for how long
The process
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes an hour or so for a single wall-mounted unit, longer for a multi-split system. A note on how to find the property and where to park makes a visit to Coates easier.
- You tell us the brand, the number of indoor units and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.
Before we arrive
- Clear a path to the units and the space around them
- Let us know where the consumer unit is
- Tell us about any building rules, permits or sign-in
How to get a quote
For a fixed-price quote, phone us on 07833 053749 or drop us a line with the address and a few details about the rooms or units involved. Photos help a lot. We reply to enquiries the same working day.

What happens if it’s left?
Drainage problems tend to grow. What starts as a damp patch under the indoor unit can become water running down the wall, so it’s worth clearing before that happens. A system that’s left with a fault, or without a service, usually costs more to run.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.
