About our commercial air conditioning in Dunn Street
Where equipment generates heat around the clock, the cooling has to keep pace. We look at the heat load and how the room is used, and can discuss backup units, so a single fault doesn’t leave the room without cooling. If the problem is server rooms running too warm and ageing air conditioning that keeps breaking down, we can help.
In a village like Dunn Street, commercial air conditioning is normally for a pub, a shop, a surgery, a village hall or a rural business. Older buildings may be listed, so planning comes first.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Before you call an engineer
Some faults have simple causes you can check first: 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 ring 07833 053749 or use the quote form.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Why act early in Dunn Street
F-gas leak checks and records are legal duties for most systems at or above 5 tCO2e. Missing checks leaves gaps in the records, and it’s simpler to keep on schedule with a contract. Waiting rarely makes an air conditioning problem smaller.
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before we start, and the quote sets out the VAT.

Dunn Street questions
Is Dunn Street in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Dunn Street is part of that. Get in touch with the details and we reply the same working day.
How do I get a quote for commercial air conditioning in Dunn Street?
The easiest way is to phone 07833 053749 or fill in the contact form with a few details and photos. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
How often is a TM44 inspection needed?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
Which commercial systems do you fit?
From one wall-mounted unit to VRF across several floors. Cassettes and ducted units suit offices, shops and restaurants.

How it works
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes from a couple of days for a few cassettes to a planned programme for a whole building, and we tidy up before we leave. Pictures of the space and where the outdoor unit could go let us plan the work in Dunn Street.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Mention any roof access, ladders or high-level work
- Let us know where the consumer unit is
How to get a quote
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, phone 07833 053749 or send an email.

Common problems we fix in Dunn Street
A fit-out, refurbishment or change of use often means rethinking the air conditioning. More people, new walls or extra equipment alter what the system has to cope with and the system needs to match the new layout.
Keep an eye out for these signs:
- Ageing air conditioning that keeps breaking down
- Systems over 12 kW due a TM44 inspection
- Buildings that can’t close for the work
Before any plant goes outside a building like Church of St Peter, its trustees may need planning or heritage advice, and we work with whoever gives it.
Comparing quotes
- Whether they looked at the job before pricing it
- What’s in the price and what is not
- Whether a new circuit is included and who certifies it
