Cooling for Lewes businesses
Food Standards Agency data counts about 50 cafés, restaurants and staff canteens, about 7 schools and colleges and about 4 care homes, nurseries and hospitals within roughly a mile and a half of the centre of Lewes. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
Around Lewes station, an office brief might cover an open-plan floor, meeting rooms and a comms cupboard, each with its own needs. If you look after a school such as Lewes Old Grammar School, classroom, office and IT room cooling is usually installed in the holidays.

Commercial air conditioning for homes and businesses in Lewes
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 carry out the checks, keep the records and tell you when the next one is due. If the problem is comms rooms without enough cooling and work raised by a TM44 inspection, we can help.
Around Lewes, commercial work is mostly shops, offices, cafés, restaurants and clinics. Cassette units in the ceiling suit open spaces, and wall-mounted or ducted units suit smaller rooms.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Lewes: your questions answered
Is air conditioning in Lewes permitted development?
It depends on the property. Central Lewes sits inside the Lewes Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Lewes council, which is usually the planning authority for Lewes.
Can you do commercial air conditioning in Lewes?
Yes. We work across London and the South East from our base in East Grinstead, and Lewes is part of that. Tell us a little about the job and we’ll take it from there.
Can you look after our air conditioning after it’s installed?
Yes, with visits planned around the site. There’s also a 24/7 emergency line for breakdowns.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
What types of commercial air conditioning do you install?
From one wall-mounted unit to VRF across several floors. Cassettes and ducted units suit offices, shops and restaurants.
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.

Owner checks or an engineer?
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Why act early in Lewes
One failing outdoor unit can affect many rooms. Planned maintenance catches issues before they grow, and keeps the system running the way it was designed to. It’s easier to plan the job in Lewes before the warm weather arrives.
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all play a part.
Why book with us
- A fixed price before any work starts
- Leading brands including Daikin, Mitsubishi Electric and Fujitsu
- Enquiries answered the same working day
- Covering London and the South East
The process
The work area is kept tidy throughout, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes anything from a day or two for a small office to several weeks of phased work on a large building. The more we can see first, the quicker the visit to Lewes.
- 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.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Find the manual or the paperwork for the system, if you have it
- Unlock any gate, garage or side passage we need
Getting a price
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price so you know the cost before we begin.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
