How we handle commercial air conditioning in Coates
Commercial systems are commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, and a fixed-price quote follows. So you know exactly what you are getting and what it costs. The work covers wall-mounted split systems, ducted systems and VRF systems, and people most often call us about new tenancies needing cooling and heating and work raised by a TM44 inspection.
If you run a village hall or similar building near Coates, heating and cooling that warms up fast suits a space used on and off.
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.

Why deal with it now?
Small faults in a commercial system can spread to the whole building’s comfort. Regular servicing finds problems early and keeps the building comfortable. Waiting rarely makes an air conditioning problem smaller.

Coates questions
Will you come out to Coates?
Yes. Coates is within the area we cover across London and the South East. 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 Coates?
It depends on the property. There’s a conservation area, the Coates Conservation Area, close to central Coates. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the planning department at Chichester council, typically the authority for Coates.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Will I get records for the system?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
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.
