Commercial air conditioning in Merston
Air conditioning systems with an effective rated output over 12 kW must have 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. The work covers ducted systems, wall-mounted split systems and VRF systems, and common reasons people get in touch are workspaces that overheat on warm days and fit-outs and refurbishments that need new air conditioning.
For a hall or similar building near Merston, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

The process
Every visit follows the same order: check the plan with you, put the dust sheets down, carry out the job, test what we have done and explain it all to you. On site, the work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Photos of the existing unit help with repairs and servicing in Merston.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Tell us about parking and loading
- Let us know if the units are on a roof, a high wall or in a locked area

What you can do yourself, and what needs us
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
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 phone 07833 053749.
Commercial air conditioning around Merston
The FSA’s food hygiene register shows about 7 cafés, restaurants and staff canteens, about 3 schools and colleges and about 4 care homes, nurseries and hospitals within roughly a mile and a half of the centre of Merston. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms.
Churches and halls such as Church of St Giles are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.

Most people get in touch when they notice one of these:
- Workspaces that overheat on warm days
- Planning ahead for the HFC phase-down

For a school like North Mundham Primary School, air conditioning work is best done out of term.

Your questions about commercial air conditioning in Merston
Do I need planning permission for air conditioning in Merston?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 4 buildings and structures within half a mile of the centre of Merston. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Merston, usually Chichester council).
Will you come out to Merston?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
What types of commercial air conditioning do you install?
We install wall-mounted, cassette, ducted, multi-split and VRF systems. The right one depends on the building and how it’s used.
How much time does a commercial air con install need?
As a guide, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Phased or out-of-hours work may extend it though it keeps disruption down.
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.”
