What happens on the day
If the system has to be off for part of the visit, we tell you before we start, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. For a village like Leigh, tell us about narrow lanes, gates and parking when you book.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- We agree the timing, with evening, weekend or phased work as needed.
- The system is installed, wired and connected to its controls.
- We commission the system and hand over the F-gas records and controls.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Make sure someone can let us in at the agreed time
- Plan for pets to be kept clear during the visit

Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Advice
Commercial air conditioning in Leigh
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor. We do not carry out the inspection itself, but we prepare the system and do the work it recommends. If you’re dealing with changes of use that need a new layout and installs that must fit around trading hours, we can help.
For a hall or similar building near Leigh, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Your questions about commercial air conditioning in Leigh
Will you come out to Leigh?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will air conditioning in Leigh need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Leigh sits inside the Leigh Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t 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 Mole Valley council, which is usually the planning authority for Leigh.
Do you install in the evenings or at weekends?
We can. We fit the installation around when the building is in use, including phased work floor by floor.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Ring 07833 053749 any time and explain the problem.
Are you TM44 assessors?
We’re not accredited energy assessors, so we do not inspect. We can prepare for the inspection and put right what it finds.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Signs you need commercial air conditioning in Leigh
Many businesses call us when an older system is struggling or failing. Parts become harder to find and the system cannot keep up, and replacing it becomes the better option.
If any of these sounds familiar, it’s worth a diagnosis:
- Ageing air conditioning that keeps breaking down
- Workspaces that overheat on warm days
- Systems over 12 kW due a TM44 inspection
Schools such as Burys Court School normally have the work done in the holidays, when classrooms are empty.

Looking after your system
Looking after it is simple, and it helps at the next service:
- Plan regular servicing with a contract
- Tell us early about fit-outs or changes of use
- Leave space around outdoor units
For systems over 12 kW, keep track of the 5-yearly TM44 inspection. We can prepare the system and act on the report.
Keep records of every service, leak check and repair. They’re part of the operator’s F-gas duties for systems that need checks.
What the work involves, system by system
F-gas records and TM44
The operator of a system at or above 5 tCO2e must have it leak checked and keep records. We carry out the checks and provide the records.
Server and comms rooms
Adding a second unit gives resilience and we can explain how they would work together.
