Commercial air conditioning in Sarratt, done properly
Every commercial job is commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, and a fixed-price quote follows. So you know exactly what you’re getting and what it costs. The work covers ceiling cassettes, VRF systems and ducted systems, and common reasons people get in touch are older systems on refrigerants that are getting scarcer and work raised by a TM44 inspection.
If you run a village hall or similar building near Sarratt, heating and cooling that warms up fast suits a space used on and off.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Your questions about commercial air conditioning in Sarratt
Is air conditioning in Sarratt permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Sarratt is in the Sarratt, The Green Conservation Area. 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 isn’t allowed under those rules. If there’s any doubt, we ask the planning department at Three Rivers council, usually the authority for Sarratt.
Is Sarratt within the area you cover?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
What types of commercial air conditioning do you install?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. The right one depends on the building and how it’s used.
Does my building need a TM44 inspection?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. GOV.UK has guidance on how it works and we’ll help with the system side.

When to call us in Sarratt
Many businesses call us when an older system is struggling or failing. Spares get scarce and performance drops so replacement starts to make more sense than repair.
The things we’re asked about most include:
- Systems over 12 kW due a TM44 inspection
- Workspaces that overheat on warm days
- Ageing air conditioning that keeps breaking down
Schools such as Sarratt Church of England Primary School normally have the work done in the holidays, when classrooms are empty.

What happens if it’s left?
One failing outdoor unit can affect many rooms. Regular servicing finds problems early and keeps the building comfortable. An early booking makes the visit to Sarratt easier to arrange.
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.

For landlords and property managers
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side and send the records to whoever needs them.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
How the visit works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. Anything unexpected is raised with you before we go further. After that, it takes from a couple of days for a few cassettes to a planned programme for a whole building. Somewhere like Sarratt, it helps to know about lanes, gates and where to park.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
Getting ready for the visit
- Name a contact who can meet us at the agreed time

Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To start, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
