AirCon Doctor works across London and the South East from East Grinstead, as an F-Gas certified company with NICEIC approval.
Getting the size right matters more than the brand: we look at the room’s size, windows, insulation and use before choosing a unit.
Villages like Dunsfold often have older houses and cottages, some of them listed. That matters, because a listed home needs consent and permitted development rules do not apply to it.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Honest limits
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Draughts and missing insulation
- Work that needs permission from a landlord or the council

What else we do in Dunsfold
What an install looks like in Dunsfold
The last census (2021) found about 78% of households in detached or semi-detached houses. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Older streets near Church of St Mary and All Saints may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. Starting with one room is common, and the outdoor unit can be chosen with more rooms in mind.

How the visit works
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes a day or more, depending on the number of rooms, the pipe routes and the access. Somewhere like Dunsfold, it helps to know about lanes, gates and where to park.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- 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.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Make sure someone can let us in at the agreed time
- Keep pets and children away from the work area

What affects the cost of air conditioning
We quote each job individually. These are the things that affect it:
- Whether it’s a one-off job or part of a maintenance contract
- How many units are involved
- Whether the existing supply is suitable
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
Before you get in touch
To help us quote quickly, please include:
- The make and model of the system, from the label
- Your installation or service records
- A photo of the consumer unit with the cover closed
Photos are the fastest route to a quote: 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. Add the address and what you’d like done, and many jobs can be priced from that.
Owner checks or an engineer?
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.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749 or use the quote form.
FAQs for Dunsfold
Is Dunsfold within the area you cover?
Yes. Dunsfold is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Will air conditioning in Dunsfold need planning permission?
It depends on the property. There’s a conservation area, the Dunsfold Conservation Area, close to central Dunsfold. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Waverley council, typically the authority for Dunsfold when it matters.
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.
Will you need to do electrical work?
In most cases. The fuse board is checked on the survey, and any electrical work goes on the quote, and our NICEIC approval covers the installation and certificate.
Do you survey before quoting?
Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.
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 fit air conditioning in a leasehold flat?
In many cases, but permissions come first. You’ll usually need the landlord’s or management company’s consent for the outdoor unit and the pipe route and the lease will say. Planning rules for flats are tighter too, so we point out anything that may need permission on the survey. This is general information, not legal advice.
