Commercial air conditioning for homes and businesses in Addlestone
Commercial air conditioning is a big part of what we do, for businesses in Addlestone and the rest of Surrey. Offices, shops, restaurants, hotels, schools and server rooms all come with different demands and we choose the system to suit the space and the way it’s used. The work covers VRF systems, ducted systems and multi-split systems, and common reasons people get in touch are systems over 12 kW due a TM44 inspection and R410A systems getting dearer to top up.
Businesses near Addlestone often have room for outdoor units on the ground at the back, which keeps them out of sight and easy to service.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

The process
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes anything from a day or two for a small office to several weeks of phased work on a large building. Getting to the outside of the property matters more than parking in a place like Addlestone.
- We survey the site and talk through how each area is used.
- You get our recommendation and a fixed price.
- We agree the timing, with evening, weekend or phased work as needed.
- The system is installed, wired and connected to its controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
How to prepare
- Unlock any gate, garage or side passage we need
- Name a contact who can meet us at the agreed time
- Mention any roof access, ladders or high-level work

What we are called out for in Addlestone
A fit-out, refurbishment or change of use often means rethinking the air conditioning. New partitions, more staff or different equipment change the heat load, and the system has to match.
Common reasons people call us include:
- Commercial systems near the end of their life
- Older systems on refrigerants that are getting scarcer
- Staff complaining about the temperature
A bursar or site manager at a school like Darley Dene Primary School will want the install planned around the school calendar, and we work to that.

Addlestone questions
Do you cover smaller places like Addlestone?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Is Addlestone in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Addlestone is part of that. Just phone us on 07833 053749, or email if that’s easier with a few details.
How much does commercial air conditioning cost?
We price commercial work after visiting the site. It means the system and the programme fit your building, and the quote you get is fixed.
How often is a TM44 inspection needed?
Over 12 kW, a TM44 inspection is needed at least every 5 years. GOV.UK has guidance on how it works, and we can help you prepare.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
What F-gas duties does a business have?
The duties depend on how much refrigerant the system holds. From 5 tCO2e, leak checks and records are needed with automatic leak detection at 500 tCO2e and above.
Do you protect the property while you work?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Rented and managed buildings
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side, and the paperwork can go to both.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what commercial air conditioning will not do:
- Major builder’s work such as new openings in structural walls
- Formal planning decisions, which rest with the council
- Boiler installation or repair
If in doubt, ring 07833 053749 or email us and we’ll say what we think.

Business air conditioning in Addlestone
The FSA’s food hygiene register shows about 83 restaurants, cafés and canteens, about 18 schools and colleges and about 17 care homes, nurseries and hospitals within 1.5 miles or so of the middle of Addlestone. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as Sayes Court Lodge (grade II). That matters for air conditioning: permitted development doesn’t apply within the grounds of a listed building, in a conservation area the outdoor unit cannot go on a wall or roof facing a road, and a unit used only for cooling isn’t covered at all, so we check with Runnymede council, normally the planning authority here where needed.
If you look after a church or hall such as St Paul's, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.
