- F-gas leak checks and records that are overdue

Common problems we fix in West Green
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.
The things we are asked about most include:
- Older systems that cannot keep up
- Planning ahead for the HFC phase-down
- Missing F-gas records for commercial systems
Schools such as West Green Primary School normally have the work done in the holidays, when classrooms are empty.

About our commercial air conditioning in West Green
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 don’t carry out the inspection itself, but we prepare the system and do the work it recommends. Typical jobs include comms rooms without enough cooling and R410A systems getting dearer to top up, on server and comms room cooling, ducted systems and VRF systems.
Around West Green, many businesses choose systems that heat as well as cool, which can replace old heaters in shops and offices.
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.

Common questions in West Green
Do I need planning permission for air conditioning in West Green?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of West Green holds about 10 listed buildings and structures. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the local planning authority (for West Green, usually Crawley council).
Will you come out to West Green?
Yes. West Green is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Which commercial systems do you fit?
From one wall-mounted unit to VRF across several floors. Cassettes and ducted units are common choices for open-plan and visible spaces.
Will skipping a service affect the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How we price commercial air conditioning
A fixed price needs a few facts first. We check:
- The size of the job
- The brand, model and parts involved
- What kind of system it is
The cost depends on the type of system and how many units are involved, the access and what the work involves. You get a fixed price before we start, so there are no surprises.
What we need to know
To speed up the quote, please include:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A few pictures of the room and the wall the unit is on, or will go on
- The address and the type of property
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.
Cooling for West Green businesses
Food Standards Agency records list about 94 restaurants, cafés and canteens, about 12 hotels, B&Bs and guest houses and about 21 schools and colleges in and around West Green, up to about a mile and a half out. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. About 62% of homes across West Green and its surrounding area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 35% of households live in terraced houses, according to Census 2021 figures. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care.
If you run a surgery, clinic or pharmacy in the area around Crawley Hospital, about 0.5 miles south-west, cleanable, quiet units and regular maintenance matter.

How the visit works
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes as long as the site and the system need, from a short install to a phased project planned around opening hours, and we tidy up before we leave. Send pictures of the space and the outside wall, and we can plan the work near West Green.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- We commission it, hand it over and can set up a maintenance contract.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Unlock any gate, garage or side passage we need
- Mention any roof access, ladders or high-level work

Advice
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
