Commercial air conditioning in Ham, Greater London
Commercial air conditioning in Ham from an F-Gas certified company, with warranty terms explained brand by brand. We reply to enquiries the same working day.
- New tenancies needing cooling and heating
- Older systems on refrigerants that are getting scarcer
- Server rooms running too warm
What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Ham.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
Before we arrive
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the outdoor unit, or where it will go
- Find the manual or the paperwork for the system, if you have it
Getting a price
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

Commercial air conditioning in Ham
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we are not assessors, but we prepare systems for inspection and act on what the report finds. The work covers multi-split systems, ceiling cassettes and ducted systems, and people most often call us about work raised by a TM44 inspection and buildings that can’t close for the work.
Space for outdoor units is tight in much of London, Ham included, 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.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What commercial air conditioning cannot fix
Commercial air conditioning cannot fix everything, and we’d rather say so up front. It does not solve:
- Getting landlord or building owner approval
- Major builder’s work such as new openings in structural walls
- Carrying out the TM44 inspection itself, which needs an accredited energy assessor
If you’re not sure, just give us a ring on 07833 053749 or send an email and we will give you a straight answer.
Parts of the system we cover
- Wall-mounted split systems
- Server and comms room cooling
- Ducted systems
- Multi-split systems
- VRF systems
- Ceiling cassettes
What we’re called out for in Ham
The GB phase-down is reducing HFC supply, so refrigerants like R410A are getting scarcer and dearer for top-ups. Repairs on existing R410A systems remain legal though it’s worth bearing in mind when planning ahead.
Common reasons people call us are:
- Comms rooms without enough cooling
- F-gas leak checks and records that are overdue
- Older systems on refrigerants that are getting scarcer
For a school like Meadlands Primary School, air conditioning work is best done out of term.
Before booking anyone
- Why the equipment they’re quoting suits the job
- How VAT is shown, and which rate applies
- Whether you get F-Gas records where refrigerant is involved
Cooling for Ham businesses
Food Standards Agency data counts about 146 restaurants, cafés and canteens, about 21 schools and colleges and about 20 care, childcare and hospital premises within roughly a mile and a half of the centre of Ham. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule. The Valuation Office Agency’s council tax figures date about 63% of homes in and around Ham to the post-war years, 1945 to 1972, and about 40% of households live in terraced houses, according to Census 2021 figures. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. For London businesses, plant position, noise and access are planned with the building first.
If you look after a church or hall such as Ham Christian Centre, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

Questions from Ham
Do I need permission to put air conditioning in my flat in Ham?
Normally, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do you cover Ham for commercial air conditioning?
We do: Ham falls inside our working area. To start, phone 07833 053749, or email if that’s easier with a few pictures.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
Can you work around our opening hours?
Yes, timing is agreed to suit you. Shops, offices, restaurants and schools all have different needs and the plan reflects it.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
What happens if it’s left?
TM44 inspections are required at least every 5 years for systems over 12 kW. The recommendations often point to simple improvements and we can do the work they recommend. If a lease or managing agent is involved in Ham, start the conversation early.
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
