Northfields commercial air conditioning
Commercial air conditioning in Northfields from an F-Gas certified company, with warranty terms explained brand by brand. We reply to enquiries the same working day.
- IT rooms that need resilient cooling
- R410A systems getting dearer to top up
- Older systems that cannot keep up
Pricing commercial air conditioning in Northfields
The survey or diagnosis tells us what the work involves. We look at:
- The brand, model and parts involved
- The distance and route between the indoor and outdoor units
- Whether we need access equipment for high-level work
The price reflects the work, not guesswork. That is why every job is looked at first, and the price is agreed before any work starts.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The postcode and whether it’s a home, flat or business
- The paperwork from the last service, if you have it
- The fuse board and where it is in the property
To help us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Then phone 07833 053749 or drop us a line.
Commercial air conditioning for homes and businesses in Northfields
We design, install and look after air conditioning for businesses in Northfields and across Greater London. That includes offices, shops, restaurants, hotels, schools and server rooms, and each one gets a system chosen for how the space is used. The work covers wall-mounted split systems, ceiling cassettes and VRF systems, and common reasons people get in touch are R410A systems getting dearer to top up and commercial systems near the end of their life.
London buildings in Northfields can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems keep outdoor plant down by serving many rooms from few outdoor units.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

The process
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes as long as the site and the system need, from a short install to a phased project planned around opening hours, and we tidy up before we leave. Send us a few phone photos and we can often price a straightforward job in Northfields before visiting.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- The programme is agreed, including any out-of-hours or phased work.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
Getting ready for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Plan for pets to be kept clear during the visit
Getting a price
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price so you know the cost before we begin.

Business air conditioning in Northfields
Food Standards Agency records list about 444 cafés, restaurants and staff canteens, about 13 hotels, B&Bs and guest houses and about 53 schools and colleges within 1.5 miles or so of the middle of Northfields. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. The Valuation Office Agency’s council tax figures put about 63% of homes in Northfields and the neighbourhoods around it before 1919, and about 36% of households live in terraced houses, according to the last census (2021). In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. London commercial jobs typically involve a landlord or managing agent, and plant space is often tight.
For a surgery or clinic in the Ealing Hospital area, a planned maintenance contract keeps the system clean and its records up to date. For a school like Mount Carmel Catholic Primary School, air conditioning work is best done out of term.
Northfields is about 1 mile south of Ealing, in Greater London. Northfields 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. Northfields is one of 764 places in Greater London where we work. London, roughly 9 miles off, has its own page on this site.
Not far from Northfields, a recent job of ours was on Richmond Hill, Richmond (TW10), about 3 miles south: installing a Mitsubishi Electric Zubadan multi-split system serving four bedrooms, the study and the living room: six indoor units in total.
Here we cover the W5, W13 and TW8 postcode area. Getting to Northfields is easy by the A3002. If you are just outside Northfields, we cover Brentford (1 mile south-east), Gillette Corner (1 mile south-west), Brentford End (1 mile south), Osterley (2 miles south-west) and Spring Grove (2 miles south-west). We also work in nearby towns such as London (9 miles east), City of Westminster (7 miles east), Marylebone (7 miles east) and Kensington (5 miles east).
Local landmarks in Northfields
Around Northfields, our work takes us to homes and businesses near Ealing Fields High School, Great Ealing School and Ealing Park Tavern. You will also find Library for Iranian Studies (1.8 miles east) and Lammas Park (under half a mile north). For rail, the closest station is Brentford station, roughly 0.8 miles south. Other landmarks nearby include Gunnersbury Park House - Large Mansion (1.2 miles east) and Treaty Centre (3 miles south-west). Not far away are Middle Lake and Long Wood.
Your questions about commercial air conditioning in Northfields
Is Northfields in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Northfields is part of that. Tell us a little about the job and we will take it from there.
Can you fit air conditioning in a London flat in Northfields?
Usually, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Which brands do you work with?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Can I do the refrigerant work 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.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
What’s the price of air conditioning for a business?
A survey comes first, then a fixed-price quote. The number of zones, the type of system, access and timing all play a part.
Looking after your system
Here’s the after-treatment advice, in brief:
- Diary TM44 inspections in advance
- Review older R410A systems before they need major repairs
- Tell us early about fit-outs or changes of use
After commissioning, you get the F-gas records, handover notes and the manufacturer’s paperwork. Keep them together for future servicing and inspections.
Make sure filters are maintained and outdoor units have space. Restricted airflow puts strain on the whole system.
What air conditioning will not do
Commercial air conditioning can’t fix everything, and we’d rather say so up front. It does not solve:
- Plumbing beyond the condensate drainage
- Issuing TM44 reports
- Structural alterations to the building
Not sure which it is? You can ring us on 07833 053749 or fill in the contact form and we’ll tell you honestly before booking.
