What happens if it’s left?
Small faults in a commercial system can spread to the whole building’s comfort. Planned maintenance catches issues before they grow, and keeps the system running the way it was designed to. In London, hot spells can bring a rush of calls, so planning the work in Cannon Hill before summer avoids the wait.
The cost depends on the type of system and how many units are involved, the access and the parts and time the job needs. You get a fixed price before we start, so there are no surprises.

Commercial air conditioning for homes and businesses in Cannon Hill
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor. We don’t carry out the inspection itself, but we prepare the system and do the work it recommends. Typical jobs include planning ahead for the HFC phase-down and comms rooms without enough cooling, across multi-split systems, server and comms room cooling and ceiling cassettes.
Space for outdoor units is tight in much of London, Cannon Hill included, so roofs, light wells and basements are common positions. VRF systems can serve many indoor units from a small number of outdoor units.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

How the visit works
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. The work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Before a visit in Cannon Hill, we ask where the van can stop and how we reach the outdoor unit.
- 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.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Preparing for the visit
- Make sure someone can let us in at the agreed time
- Let us know where the consumer unit is
- Dig out any previous service or F-Gas records

Other services in Cannon Hill
Commercial air conditioning in Cannon Hill: local notes
Food Standards Agency records list about 212 restaurants, cafés and canteens, about 4 hotels and guest houses and about 34 schools and colleges in and around Cannon Hill, up to about a mile and a half out. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. About 61% of homes in the Cannon Hill area were built between the wars, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 39% of households in terraced houses. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. London commercial jobs normally involve a landlord or managing agent, and plant space is often tight.
If you run a surgery, clinic or pharmacy in the area around St. Anthony's Hospital, about 1.5 miles south, cleanable, quiet units and regular maintenance matter. If you look after a school such as Hillcross Primary School, classroom, office and IT room cooling is usually installed in the holidays.

Cannon Hill: your questions answered
Is Cannon Hill in your area for commercial air conditioning?
Yes, Cannon Hill is within the area we cover. Get in touch with the details and we reply the same working day.
Do I need permission to put air conditioning in my flat in Cannon Hill?
Often, yes, but the lease and the freeholder typically have a say. 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.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your pictures and details where the job is simple. Then you get a fixed-price quote.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you offer emergency call-outs?
Yes. Our emergency line runs 24/7 for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Do you offer commercial maintenance contracts?
Yes, with visits planned around the site. For breakdowns, there’s a 24/7 emergency line.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep plant areas tidy
- Budget for replacing ageing plant
- Plan the air conditioning alongside the fit-out
We show your team how to use the controls so staff can set it up properly. Getting the settings right helps the system perform.
Simple control settings help. Units heating and cooling the same space at once is a common problem and correct settings avoid it.
