What happens when you get in touch

Most commercial HVAC enquiries cannot be answered accurately over the phone, and we would rather say so than guess at a number. What we can do quickly is work out whether the problem is a maintenance issue, a design issue or a replacement decision — because those lead to very different conversations.

If it is a fault, we will ask what the symptom is and when it started, because that usually narrows the cause considerably: a system that runs but does not cool points one way, one that trips out repeatedly points another, and water dripping from a ceiling unit is almost always condensate rather than refrigerant. Our repair page sets out the common faults by symptom.

If it is a new system or a replacement, the honest answer is that it needs a survey. Cooling load comes from occupancy, lighting, equipment and solar gain, not from floor area, so a price given without a load calculation is guesswork — and it is the reason two quotes for the same building can differ by a factor of two.

What is useful to have to hand

None of this is required, and it all speeds things up considerably:

• What the building is and roughly how big. Building type tells us more than square metres — an office, a shop with an open front and a warehouse are three different problems.
• What is installed now, if anything, and roughly how old it is. If you know the refrigerant type, that matters a great deal: R22 systems cannot legally be recharged, and R410A is getting more expensive as the phase-down bites.
• What the problem actually is. "Too hot in the afternoon on the south side" is far more useful than "the air conditioning is not working".
• Any access constraints — trading hours, out-of-hours-only working, landlord restrictions on external plant, listed building or conservation area status.
• Whether you hold F-Gas records and a TM44 report. If you do not know, that is worth establishing regardless of this enquiry — see servicing and TM44.

Who we work with

We work with building owners, facilities managers, tenants, managing agents and contractors across commercial, industrial and public buildings — offices, retail, warehousing, hospitality, care and light industrial. Building-type specifics are on our sectors pages, and the areas we cover are listed under locations.

If you would rather see indicative numbers before speaking to anyone, the cost guides set out ranges by system type and the cost estimator will give you a first-pass figure.
