Commercial air conditioning for homes and businesses in Heston
Heating, cooling and fresh air often go together. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside for a joined-up system. Common call-outs are for comms rooms without enough cooling and leak check schedules that have slipped, on ducted systems, wall-mounted split systems and server and comms room cooling.
In a London area like Heston, commercial air conditioning goes into offices, shops, restaurants and server rooms, often in shared buildings. So landlord consent, plant positions and noise all need agreeing first, and the work is typically planned around trading hours.
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.

Managing agents and facilities teams in Heston
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.

Looking after your system
After the visit, a few habits help:
- Keep plant areas tidy
- Track when the next TM44 inspection is due
- Agree sensible control settings for each area
If the system needs F-gas leak checks, we diary the first one and we can cover it under a contract.
Plan replacements before old systems fail especially where top-up refrigerant is getting harder to buy.
Commercial air conditioning in Heston: local notes
The FSA’s food hygiene register shows about 275 cafés, restaurants and staff canteens, about 15 hotels and guest houses and about 37 schools and colleges within about 1.5 miles of central Heston. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. London commercial jobs typically involve a landlord or managing agent, and plant space is often tight.
For a church or hall like St Leonard's Church, any outdoor unit needs the right consents first. If you look after a school such as Westbrook Primary School, classroom, office and IT room cooling is usually installed in the holidays.
Heston is about 2 miles south of Southall, in Greater London. Heston gets the same approach as every job we take on: a look at the job first, a fixed-price quote and written records at the end.

The closest recent job we can point to from Heston was on King Street, Twickenham (TW1), about 3 miles south-east: installing a Samsung VRF system serving the restaurant dining area, bar, private dining room and kitchen extraction area: seven indoor units in total.

Your questions about commercial air conditioning in Heston
Do I need planning permission for air conditioning in Heston?
It comes down to the building and the spot chosen for the outdoor unit. There’s a conservation area, the Heston Village Conservation Area, close to central Heston. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the planning department at Hounslow council, normally the authority for Heston.
Do you cover Heston for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Heston is part of that. To start, ring us on 07833 053749 or email us with a few photos.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Do I need to service the system to keep 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.
Can you come out in an emergency?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
How long does a commercial installation take?
It takes a few days for a small shop or office, longer for VRF across several floors. The scale and programme decide most of it, and we set out the timing with your quote.
What we do, step by step
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, the work takes a few days for a small shop or office, longer for VRF across several floors. Photos of the room and where the outdoor unit could go let us plan most of a visit to Heston in advance.
- 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.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- Commissioning, F-gas records and a handover of the controls finish the job.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Make sure someone can let us in at the agreed time
- Clear the space around the indoor unit, or where it will go
How to get a quote
To help us quote: the address and the type of property, photos of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, phone 07833 053749.
