System by system
Offices
Office cooling has to cope with people, computers, lighting and sunshine. The system is sized for what the space really needs and choose units that suit the ceiling and layout.
Hotels and schools
Schools often need installs during the holidays and we plan the programme early.
How it works
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. The visit takes from a couple of days for a few cassettes to a planned programme for a whole building. Photos of the room and the outside wall help us plan a job near St Denys.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- We commission it, hand it over and can set up a maintenance contract.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go

- Unlock any gate, garage or side passage we need

Commercial air conditioning in St Denys: local notes
St Denys is within about 2 miles of the coast. Rooftop and wall-mounted plant near the sea needs protecting from salt air, through position, coil coatings where available and regular maintenance. There are about 208 restaurants, cafés and canteens, about 15 hotels and guest houses and about 37 schools and colleges within 1.5 miles or so of the middle of St Denys, according to the Food Standards Agency’s register. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. Draw a one-mile circle round the middle of St Denys and it takes in 5 conservation areas. Church of St Denys, listed at grade II, is one of roughly 10 protected buildings and structures in the half-mile around St Denys’s centre. None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit.
If you look after a school such as St Denys Primary School, classroom, office and IT room cooling is typically installed in the holidays. If you run a surgery, clinic or pharmacy in the area around Royal South Hants Hospital, about 0.9 miles south-west, cleanable, quiet units and regular maintenance matter.

What you can do yourself, and what needs us
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Your questions about commercial air conditioning in St Denys
Is the coast a problem for outdoor units in St Denys?
It can. St Denys is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Will you come out to St Denys?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you protect the property while you work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
What’s the price of air conditioning for a business?
After a site survey, with a fixed-price quote. Factors include the number of areas, the system type, access and any out-of-hours or phased work.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
