South Merstham commercial air conditioning
Commercial air conditioning in and around South Merstham, from a site survey or diagnosis to sign-off and a fixed price agreed before any work starts.
- Offices that get too hot in summer
- Older systems on refrigerants that are getting scarcer
- Leak check schedules that have slipped
Keeping the system healthy
After the visit, a few habits help:
- Keep plant areas tidy
- Involve us at the planning stage of a refurbishment
- Agree sensible control settings for each area
For systems over 12 kW, keep track of the 5-yearly TM44 inspection. When it comes round, we can get the system ready and carry out the recommendations.
Good records make inspections and audits easier. They’re part of the operator’s F-gas duties for systems that need checks.
Commercial air conditioning in South Merstham, done properly
The business that operates the system has F-gas responsibilities. Leak checks and records are required for systems from 5 tCO2e upwards. We carry out the checks, keep the records and tell you when the next one is due. Common call-outs are for comms rooms without enough cooling and workspaces that overheat on warm days, across ceiling cassettes, wall-mounted split systems and ducted systems.
For a business near South Merstham, there’s usually space for plant at the rear, which keeps them tidy and easy to reach.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

South Merstham questions
Do you cover smaller places like South Merstham?
Yes. South Merstham 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.
Can you do commercial air conditioning in South Merstham?
We do: South Merstham falls inside our working area. Tell us a little about the job and we’ll take it from there.
Are you TM44 assessors?
TM44 inspections are carried out by accredited energy assessors, which we are not. We get the system ready and act on the findings.
When will I hear back?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Will skipping a service affect the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How the job changes from property to property
Server and comms rooms
Server rooms generate heat all day and night, so the cooling has to run continuously. The design is based on the equipment’s heat output.
Ducted systems
One ducted unit can serve more than one area, depending on the layout.
What we do, step by step
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. Because we plan from photos or a survey, a job in South Merstham can usually be finished in one visit.
- 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.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Let us know where the consumer unit is
- Unlock any gate, garage or side passage we need
- Find the manual or the paperwork for the system, if you have it
