How we handle commercial air conditioning in Thornton Heath
There’s no single best commercial system. Wall-mounted splits suit small offices and single rooms, cassettes suit open ceilings, ducted units hide away in ceiling voids, and VRF or VRV serves many rooms from shared outdoor units. We set out the choices and the reasons behind our recommendation. If you’re dealing with installs that must fit around trading hours and IT rooms that need resilient cooling, we can sort it out.
London buildings in Thornton Heath can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems can serve many indoor units from a small number of outdoor units, which helps in dense areas.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749 or use the quote form.

How the visit works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Parking bays, permits and roof or balcony access are the first things we ask about in Thornton Heath.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we’re working in
- Dig out any previous service or F-Gas records

Advice
Thornton Heath: your questions answered
Do you cover Thornton Heath for commercial air conditioning?
Yes. Thornton Heath is one of the places we cover. Get in touch with the details and we reply the same working day.
Can you fit air conditioning in a London flat in Thornton Heath?
Normally, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book, and we’re happy to show ours.
Which commercial systems do you fit?
Wall-mounted, multi-split, ducted, cassette and VRF systems from leading brands. We set out the choices after surveying the site.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
When to call us in Thornton Heath
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine, and opening windows does not always help. Air conditioning sized to the actual heat gain keeps the space comfortable.
Any of these is worth a proper look:
- R410A systems getting dearer to top up
- Systems over 12 kW due a TM44 inspection
- Fit-outs and refurbishments that need new air conditioning
For a school like Winterbourne Junior Girls' School, air conditioning work is best done out of term.
