Commercial air conditioning in Old Coulsdon, done properly
Businesses cannot always stop for an installation. Work can be done in the evening, at weekends or in phases, so the building keeps running. The programme is agreed before any work starts. The work covers ceiling cassettes, multi-split systems and wall-mounted split systems, and people most often call us about leak check schedules that have slipped and ageing air conditioning that keeps breaking down.
For a business in Old Coulsdon, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the records and tell you what’s due.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

The process
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. Let us know who controls access to the building in Old Coulsdon, as that saves time on the day.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- We commission it, hand it over and can set up a maintenance contract.
Preparing for the visit
- Arrange for someone to be there to let us in
- Keep pets out of the rooms we are working in
- Have the make and model of any existing unit to hand

Questions from Old Coulsdon
Do you cover Old Coulsdon for commercial air conditioning?
We do: Old Coulsdon falls inside our working area. Tell us a little about the job and we’ll take it from there.
Will air conditioning in Old Coulsdon need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Old Coulsdon holds about 6 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Old Coulsdon, usually Croydon council).
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
How do you keep the place clean during the work?
Protection goes down first: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
What the work involves, system by system
Shops and restaurants
Where appearance matters, ducted or cassette units keep equipment out of sight.
Ducted systems
The unit needs room in the void and an access hatch for filters, drain and fan to be serviced.
When it’s something else
To be straight with you, there are a few things this work will not fix:
- Boiler installation or repair
- Building work beyond the installation itself
- Formal planning decisions, which rest with the council
Not sure which it is? You can phone us on 07833 053749 or fill in the contact form and we will tell you honestly before booking.
Parts of the system we cover

What else we do in Old Coulsdon
Leave it or put it right?
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 a maintenance contract keeps them on track. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Old Coulsdon early.
The price reflects the work, not guesswork. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before any work starts.
