Caterham air conditioning
Need air conditioning in Caterham? We look at the job first, give you a fixed-price quote and do the work at a time that suits you, then sign it off with written records.
- Bedrooms and offices that overheat in summer
- A loft conversion that is too warm to use
- Not knowing which system, size or brand to choose
How we handle air conditioning in Caterham
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. A lot of the calls we get from Caterham are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Around Caterham, older homes and newer ones sit side by side, and that changes how the pipework goes in. Older solid walls need more drilling than modern cavity walls, while a loft space can hide pipe runs that would otherwise be on the outside.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Rented and managed buildings
We also work for facilities teams in offices, schools and public buildings in Caterham and across Surrey. Larger buildings can be done in stages around the people who use them.
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.
Honest limits
Air conditioning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- A ventilation problem rather than a temperature problem
- Building damp that has a structural cause
- Draughts and missing insulation
If in doubt, phone 07833 053749 or write to us at info@aircondoctor.co.uk and we will say what we think before you book.

FAQs for Caterham
Can I get a fixed-price quote for air conditioning in Caterham?
The easiest way is to ring 07833 053749 or send an email with a few details and pictures. We reply the same working day, and the quote is fixed before any work starts.
Can you do air conditioning in Caterham?
Yes. We work across London and the South East from our base in East Grinstead, and Caterham is part of that. Just phone us on 07833 053749 or send an email with a few details.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Do you look at the job first?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
Do I need a new electrical circuit?
Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we install and certify it as part of the job.
Which type of air conditioning is best?
There’s no single best type. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. The survey ends with a recommendation and the reasons.
Common problems we fix in Caterham
Rooms overheat mostly because of heat they gain during the day. Sunshine through glazing, especially on south and west-facing rooms, adds a lot of heat, and once the room has warmed up, it holds on to it into the evening.
Reasons to give us a call include:
- Portable units that are noisy and barely cope
- A study or office that overheats during the day
- Rooms that get too hot to sleep or work in
Plenty of people near Caterham station split the week between the train and a spare room, and that spare room is often the first to get a unit.
Questions to ask before booking
- How extra work would be agreed if they find something unexpected
- If the figure could change on the day
- Whether testing, commissioning and paperwork are included

One of our jobs in Caterham
Godstone Road, Caterham (CR3)
- Property
- A detached 1930s house.
- Work carried out
- Installation of a Samsung multi-split system serving three bedrooms and a home office. The 1930s cavity wall construction made installation relatively straightforward. The outdoor unit was positioned on the side return, away from the rear garden and below the level of the fence.
- Outcome
- The client, who works from home three days per week, reported that the home office was now productive year-round. The bedroom units have been particularly valued during the hot summers the area has experienced in recent years.

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. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Let us know about side gates, ladders or locked areas at your property in Caterham.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Name a contact who can meet us at the agreed time
- Have the make and model of any existing unit to hand
Ask for a quote
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.
