Air conditioning in Walton-on-Thames, done properly
Think of it as diagnose, treat and sign off: survey first, install second, commission and hand over last. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. A lot of the calls we get from Walton-on-Thames are about one room that is too hot to sleep or work in. That’s normally a single wall-mounted split, from £1,200 + VAT.
Around Walton-on-Thames, older homes and newer ones sit side by side, and that changes how the pipework goes in. Solid walls take longer to core drill than cavity walls, and a loft or a void can hide a pipe run that would otherwise be on show.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

How the job changes from property to property
Wall-mounted split systems
Wall-mounted units suit bedrooms, living rooms, home offices and small commercial rooms. The unit goes where it spreads the air well and the filters are easy to reach, and away from where the air would blow straight onto people.
Ducted systems
Ducted air conditioning hides the indoor unit in a ceiling void or loft, and all you see is a discreet grille. It’s popular where people do not want a unit on the wall.
How it 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. After that, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Photos of the room and the outside wall help us plan a job in Walton-on-Thames.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit
- Clear a path to the units and the space around them
How to get a quote

Pricing air conditioning in Walton-on-Thames
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a simple split or a larger system
- The brand, model and parts involved
- The number of rooms, units or zones
The cost depends on the type of system and how many units are involved, the access and the parts and time the job needs. We give you a fixed price before any work starts, so there are no surprises.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- The postcode and whether it’s a home, flat or business
- A photo of the consumer unit with the cover closed
- The remote or wall controller showing any error
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. To get one, phone 07833 053749, or email if that’s easier.

When something else is needed
Not every problem is solved by air conditioning, and we’ll tell you before we start. It doesn’t solve:
- Damp from leaks or a lack of ventilation
- Gas boiler or central heating faults (we don’t work on gas boilers)
- Stuffy rooms that need fresh air rather than cooling
If in doubt, ring 07833 053749 and we’ll say what we think before booking.

Walton-on-Thames: your questions answered
Is Walton-on-Thames in your area for air conditioning?
We do: Walton-on-Thames falls inside our working area. To start, call 07833 053749 or email us with a few photos.
Can I get a fixed-price quote for air conditioning in Walton-on-Thames?
The easiest way is to phone us on 07833 053749 or drop us a line with a few details and photos. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Does air conditioning need its own electrical supply?
Most systems need their own supply from the consumer unit. Under Part P, a new circuit has to be notified unless a registered competent person does it, and we’re NICEIC approved, so we can install and certify it.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking, and we are happy to show ours.
Will skipping a service affect the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
