What we do, step by step
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. A visit in Farnham is booked for a time that suits you.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Before we arrive
- Keep pets out of the rooms we are working in
- Have the make and model of any existing unit to hand
- Arrange for someone to be there to let us in

About our commercial air conditioning in Farnham
Commercial air conditioning comes with F-gas duties for the operator. Leak checks and records are required for systems from 5 tCO2e upwards. We carry out the checks, keep the records and tell you when the next one is due. The work covers wall-mounted split systems, server and comms room cooling and ceiling cassettes, and common reasons people get in touch are commercial systems near the end of their life and fit-outs and refurbishments that need new air conditioning.
Around Farnham, commercial work is mostly shops, offices, cafés, restaurants and clinics. Cassette units in the ceiling suit open spaces, and wall-mounted or ducted units suit smaller rooms.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Commercial air conditioning in Farnham: local notes
The FSA’s food hygiene register shows about 56 restaurants, cafés and canteens, about 3 hotels, B&Bs and guest houses and about 10 schools and colleges within roughly a mile and a half of the centre of Farnham. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
For premises near Farnham station, we plan plant positions and working hours with the landlord or managing agent first, where there is one. Churches and halls such as St Joan of Arc's Church are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.
Farnham is about 6 miles south of Farnborough, in Surrey. Properties in Farnham get the same service as everywhere we cover: a look at the job first, a fixed-price quote and written records at the end. Farnham is one of 395 places in Surrey we cover. Guildford, roughly 10 miles off, has its own page on this site.
A recent job of ours in Farnham was on Castle Street (GU9): installing a Fujitsu multi-split system serving three offices and a client meeting room.
Our working area takes in GU9 and GU10. You’ll find Farnham on the A31 and A287, so it’s easy for us to get to for surveys and visits. Close by, we work in Compton (1 mile east), Hale (1 mile north), Upper Hale (2 miles north), Runfold (2 miles east) and Heath End (2 miles north). We also work in nearby towns such as Guildford (10 miles east), Woking (12 miles north-east), Camberley (9 miles north) and Frimley (8 miles north).
Local landmarks in Farnham
We fit and service air conditioning in homes and premises around Moor Park, William Cobbett Public House and Weydon School and the streets around them. Farnham has its own railway station: Farnham station. A little further out are Museum of Farnham (less than half a mile north-west) and Farnham Castle (0.6 miles north-west). The countryside around Farnham includes Farnham Park and Aunt's Pool.
Why deal with it now?
In a comms room, losing the cooling can soon become serious. Designing in a backup unit or reviewing the existing set-up is worth doing before anything goes wrong. A system that’s left with a fault, or without a service, typically costs more to run.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you’ll get one fixed price.

FAQs for Farnham
Do I need planning permission for air conditioning in Farnham?
The answer turns on the property and where the outdoor unit would sit. Central Farnham is a short walk from the Farnham Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Waverley council, which is normally the planning authority for Farnham.
Is Farnham in your area for commercial air conditioning?
Yes. Farnham is one of the places we cover. To start, ring 07833 053749 or send an email with a few photos.
Do you install in the evenings or at weekends?
We can. Work can be scheduled around your hours, including phased work floor by floor.
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 landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
What are the F-gas responsibilities for commercial air conditioning?
The duties depend on how much refrigerant the system holds. Systems at or above 5 tCO2e need leak checks and records, and from 500 tCO2e automatic leak detection is required.
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 call 07833 053749 or write to us at info@aircondoctor.co.uk.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
What air conditioning will not do
A few issues sit outside what this work can do:
- Plumbing beyond the condensate drainage
- Building work beyond the installation itself
- Fire risk assessments
If you are not sure, just ring 07833 053749 and we’ll give you a straight answer.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
