About our commercial air conditioning in Cotman's Ash

There’s a 24/7 emergency line for breakdowns. The work covers multi-split systems, server and comms room cooling and ceiling cassettes, and common reasons people get in touch are IT rooms that need resilient cooling and fit-outs and refurbishments that need new air conditioning.
For a business near Cotman's Ash, outdoor units normally have room at the back of the building.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

For landlords and property managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Keeping the system healthy
Looking after the system is mostly common sense. Our tips:
- Keep plant areas tidy
- File every leak check and service record in one place
- Review older R410A systems before they need major repairs
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions and you’ll know what they ask for.
Plan replacements before old systems fail, particularly where they use R410A.
Safe owner checks
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
Common questions in Cotman's Ash
Do you cover Cotman's Ash for commercial air conditioning?
Yes, Cotman's Ash is within the area we cover. Just ring us on 07833 053749, or email if that’s easier with a few details.
Is planning permission needed for air conditioning in Cotman's Ash?
The answer turns on the property and where the outdoor unit would sit. The centre of Cotman's Ash is in a conservation area. 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 needed, we check with Sevenoaks council, which is normally the planning authority for Cotman's Ash.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
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.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Cotman's Ash and across Kent. Tell us who should receive the paperwork.
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.
