What owners can safely do
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 a breaker trips again after you reset it, leave it off and call 07833 053749 or email us.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
Commercial air conditioning for homes and businesses in Crawley Down
Commercial air conditioning is a big part of what we do, for businesses in Crawley Down and the rest of West Sussex. Offices, shops, restaurants, hotels, schools and server rooms all come with different demands, and each one gets a system chosen for how the space is used. If you are dealing with new tenancies needing cooling and heating and leak check schedules that have slipped, we can help.
For a business near Crawley Down, there’s normally space for plant at the rear, which keeps them tidy and easy to reach.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

What the work involves, system by system
Ducted systems
A ducted system hides the indoor unit and feeds air to the room through grilles. They’re chosen where appearance matters in retail, hospitality and offices.
Hotels and schools
Larger buildings may need TM44 inspections at least every 5 years, and we prepare for them and act on the findings.
What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes from a couple of days for a few cassettes to a planned programme for a whole building. A few photos let us plan a visit to a place like Crawley Down.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Preparing for the visit
- Let us know where the consumer unit is
- Mention any roof access, ladders or high-level work
- Make sure someone can let us in at the agreed time

Commercial air conditioning in Crawley Down: local notes
Food Standards Agency records list about 5 restaurants, cafés and canteens and about 3 care homes, nurseries and hospitals within 1.5 miles or so of the middle of Crawley Down. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
For a surgery or clinic in the Queen Victoria Hospital area, a planned maintenance contract keeps the system clean and its records up to date. For a church or hall like All Saints Parish Church, any outdoor unit needs the right consents first.

Near you in Crawley Down
Around Crawley Down, our work takes us to homes and businesses near Imberhorne School, among other places. The nearest railway station is East Grinstead station, roughly 2.5 miles east of the centre. Well-known places in the area include Queen Victoria Hospital (3.5 miles east) and Effingham Park Motor Museum (1.4 miles north-west). Green spaces nearby include Hedgecourt Lake.
Rented and managed buildings
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
Questions from Crawley Down
Will you come out to Crawley Down?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is planning permission needed for air conditioning in Crawley Down?
It depends on the property. Historic England lists about 4 buildings and structures within half a mile of the centre of Crawley Down. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the planning department at Mid Sussex council, normally the authority for Crawley Down.
Are you TM44 assessors?
No, the inspection needs an accredited energy assessor. We can prepare for the inspection and put right what it finds.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
How much time does a commercial air con install need?
As a guide, it takes from a couple of days for a few cassettes to a planned programme for a whole building. Phased or out-of-hours work may extend it though it keeps disruption down.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
