Commercial air conditioning in Longfield, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out. We do not carry out the inspection itself, but we prepare the system and do the work it recommends. Common call-outs are for workspaces that overheat on warm days and new tenancies needing cooling and heating, on VRF systems, multi-split systems and wall-mounted split systems.
Around Longfield, there’s normally space for outdoor plant away from the road, out of sight and away from neighbours.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

When it’s something else
Commercial air conditioning can’t fix everything, and we’d rather say so up front. It does not solve:
- Building work beyond the installation itself
- Gas boiler or heating plumbing work
- Planning permission or landlord consent on your behalf
If you’re not sure, just ring us on 07833 053749, or email if that’s easier and we will give you a straight answer.
Parts of the system we cover

Do you need commercial air conditioning in Longfield?
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine and windows alone can’t always shift it. A system sized for the real heat load deals with it.
It’s time to call us if you are dealing with:
- F-gas leak checks and records that are overdue
- Ageing air conditioning that keeps breaking down
- R410A systems getting dearer to top up
Around Longfield station, an office brief might cover an open-plan floor, meeting rooms and a comms cupboard, each with its own needs.
Before booking anyone
- Whether the company is F-Gas certified, and whether you can check it

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: 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 call 07833 053749 or drop us a line.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
How it works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes a few days for a small shop or office, longer for VRF across several floors. Somewhere like Longfield, it helps to know about lanes, gates and where to park.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Before we arrive
- Tell us about parking and loading
- Dig out any previous service or F-Gas records
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Your questions about commercial air conditioning in Longfield
Will you come out to Longfield?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit air conditioning in Longfield without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 1 buildings and structures within half a mile of the centre of Longfield. 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 needed, we check with Dartford council, which is normally the planning authority for Longfield.
Can you look after our air conditioning after it’s installed?
Yes, and we tailor the schedule to the system and how hard it works. For breakdowns, there’s a 24/7 emergency line.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
From one of our customers
“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.”
