Air conditioning servicing in Walton-on-Thames, done properly
A service is as much a check-up as a clean. We listen to the fans, look at the pipework and insulation, test the controls and check the electrical connections are sound, and tells you about anything that looks like it’s heading for trouble. Common call-outs are for a system that struggles to cool on warm days and warning lights on the indoor unit, across air-to-air heat pumps, wall-mounted split systems and VRF systems.
A service in Walton-on-Thames typically starts with the filters and the indoor coil, then the drain, the outdoor unit and the electrics, before testing the system and checking for refrigerant leaks.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

How we price air conditioning servicing
The quote reflects the job in front of us. We take into account:
- What state the existing equipment is in
- The type of system, from a single split to a larger system
- What electrical work the job needs
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will go through it with you.
Helping us quote
When you call or email, these details help:
- A close-up of the unit’s label showing the model number
- Photos showing the indoor unit and the space around it
- Any previous service or F-Gas records
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Then call 07833 053749 or fill in the contact form.
Landlords, agents and facilities managers
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
If you look after several properties, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Walton-on-Thames questions
What’s the best way to get a price for air conditioning servicing in Walton-on-Thames?
The easiest way is to ring 07833 053749 or email us with a few details and photos. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
How often do you service systems in Walton-on-Thames?
For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.

What happens on the day

Before you call an engineer
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
