Fixed-price quotes for commercial air conditioning in Harmondsworth
Before we fix a price, we need to know a few things. We look at:
- The pipe route between the units
- What electrical work the job needs
- The brand, model and parts involved
What you pay reflects the actual work. That is why every job is looked at first, and the price is agreed before we start.
Helping us quote
You do not need the technical terms. Just send:
- Your installation or service records
- Any error code or flashing light on the display
- Wide photos of the room or the existing unit
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 on the quote. To get one, ring 07833 053749, or email if that’s easier.
Commercial air conditioning in Harmondsworth
There’s no single best commercial system. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We set out the choices and the reasons behind our recommendation. If you’re dealing with F-gas leak checks and records that are overdue and IT rooms that need resilient cooling, we can sort it out.
Commercial systems in Harmondsworth are often in shared buildings: offices above shops, restaurants below flats. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and the work is normally planned around trading hours.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

Customers usually contact us after spotting one of these:
- Buildings that can’t close for the work
- Older systems on refrigerants that are getting scarcer

Harmondsworth questions
Will air conditioning in Harmondsworth need planning permission?
The answer turns on the property and where the outdoor unit would sit. The Harmondsworth Village Conservation Area takes in the middle of Harmondsworth. 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 isn’t allowed under those rules. If there’s any doubt, we ask Hillingdon council, which is normally the planning authority for Harmondsworth.
Is Harmondsworth in your area for commercial air conditioning?
Yes, Harmondsworth is within the area we cover. Tell us a little about the job and we’ll take it from there.
Are you F-Gas certified?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Is there a survey before the work?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
How are commercial air conditioning installs priced?
After a site survey, with a fixed-price quote. The number of zones, the type of system, access and timing all play a part.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.

How it works

Photos of the room and where the outdoor unit could go let us plan most of a visit to Harmondsworth in advance.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- The system is commissioned and maintenance can be arranged.
How to prepare
- Make sure someone can let us in at the agreed time
- Mention any managing agent or landlord rules we need to follow
- Unlock any gate, garage or side passage we need
