One call covers commercial air conditioning in Dorking, from the first look to sign-off. F-Gas certified, NICEIC approved and Checkatrade members.

Commercial air conditioning in Dorking, done properly
The business that operates the system has F-gas responsibilities. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We handle the checks and records and remind you when the next is due. Typical jobs include workspaces that overheat on warm days and comms rooms without enough cooling, on ducted systems, ceiling cassettes and multi-split systems.
For a business in Dorking, we fit around opening hours, typically after hours or over a weekend, and we leave the space clean and working.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Commercial air conditioning around Dorking
The FSA’s food hygiene register shows about 59 restaurants, cafés and canteens, about 4 hotels, B&Bs and guest houses and about 10 care homes, nurseries and hospitals within about 1.5 miles of central Dorking. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule.
For a school like St Paul's CofE (Aided) Primary School, air conditioning work is best done out of term. Before any plant goes outside a building like Church of St Paul, its trustees may need planning or heritage advice, and we work with whoever gives it.
Dorking is about 10 miles north-west of Crawley, in Surrey. Dorking gets the same approach as every job we take on: diagnosis first, a fixed price and proper paperwork when we have finished. In Surrey alone we list 395 places, and Dorking is one. Reigate, roughly 6 miles off, has its own page on this site.
A recent job of ours in Dorking was on South Street (RH4): installing two Panasonic wall-mounted units: one in the main treatment room and one in the reception and waiting area.
That includes properties on High Street, Station Road and London Road and the roads around them. The A24 and A25 pass through or close to Dorking, which keeps journeys to surveys and visits simple.

We also work in nearby towns such as Guildford (11 miles west), Woking (12 miles north-west), Epsom (8 miles north) and Horley (8 miles south-east).

Different systems, different jobs
Offices
Office cooling has to cope with people, computers, lighting and sunshine. We size the system for the actual heat load and choose units that suit the ceiling and layout.
Shops and restaurants
For a discreet finish, ducted systems and cassettes are popular.
What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes anything from a day or two for a small office to several weeks of phased work on a large building. Access to the outdoor unit position is the main thing to tell us about in Dorking.
- First comes a survey, looking at the building and how it’s occupied.
- You get our recommendation and a fixed price.
- The programme is agreed, including any out-of-hours or phased work.
- The system is installed, wired and connected to its controls.
- We commission the system and hand over the F-gas records and controls.
How to prepare
- Let us know where the consumer unit is
- Plan for pets to be kept clear during the visit
- Tell us about parking and loading

Why it’s worth doing now in Dorking
Small faults in a commercial system can spread to the whole building’s comfort. Planned maintenance catches issues before they grow and keeps the building comfortable. It’s easier to plan the job in Dorking before the warm weather arrives.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered and we will price it together.

Safe owner checks
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
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 electrical side needs a competent person. If you need something moved, we can quote for it.
Dorking questions
Can you do commercial air conditioning in Dorking?
Yes. We work across London and the South East from our base in East Grinstead, and Dorking is part of that. Just phone 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Do I need planning permission for air conditioning in Dorking?
That depends on the building and where the outdoor unit goes. There’s a conservation area, the Dorking Conservation Area, close to central Dorking. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Mole Valley council, typically the authority for Dorking.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Do you carry out TM44 inspections?
We don’t carry out the inspection itself, as it needs an accredited energy assessor. Our part is getting the system ready and doing the follow-up work.
How do you keep the place clean during the work?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
