Commercial air conditioning in Fortis Green
Where equipment generates heat around the clock, the cooling has to keep pace. The design accounts for the equipment’s heat and can include a second unit as backup, so a single fault does not leave the room without cooling. The work covers wall-mounted split systems, ducted systems and server and comms room cooling, and common reasons people get in touch are workspaces that overheat on warm days and fit-outs and refurbishments that need new air conditioning.
Commercial systems in Fortis Green are often in shared buildings: offices above shops, restaurants below flats. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and installs are often done out of hours.
We’re 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.

Fortis Green questions
Will air conditioning in Fortis Green need planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Fortis Green is a short walk from the Muswell Hill Conservation Area. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the local planning authority (for Fortis Green, usually Haringey council).
Do you cover Fortis Green for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Fortis Green is part of that. To start, phone us on 07833 053749, or email if that’s easier with a few pictures.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone and we will gladly show you ours.
Can you do our TM44 air conditioning inspection?
We are not accredited energy assessors, so we don’t inspect. We can prepare for the inspection and put right what it finds.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Which manufacturers do you install and repair?
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’ll take it from there.

What else we do in Fortis Green
Commercial air conditioning around Fortis Green
Food Standards Agency data counts about 169 cafés, restaurants and staff canteens, about 51 schools and colleges and about 49 care homes, nurseries and hospitals within 1.5 miles or so of the middle of Fortis Green. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule. VOA council tax data put about 56% of homes in the Fortis Green area before 1919, and about 56% of households live in flats, according to Census 2021 figures. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
Before any plant goes outside a building like United Reformed Church, its trustees may need planning or heritage advice, and we work with whoever gives it.

What happens on the day
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes as long as the site and the system need, from a short install to a phased project planned around opening hours, and we clear up before we go. Pictures of the space and the outside wall help us plan the work in Fortis Green.

When to call us in Fortis Green
Many businesses call us when an older system is struggling or failing. Spares get scarce and performance drops, and replacing it becomes the better option.
These are the situations we see most often:
- Leak check schedules that have slipped
- Installs that must fit around trading hours
- New tenancies needing cooling and heating
If you look after a school such as Fortismere School, classroom, office and IT room cooling is typically installed in the holidays.

- Whether the company is F-Gas certified, and whether you can check it
How we price commercial air conditioning
We quote each job individually. This is what makes a difference:
- The electrical supply and whether a new circuit is needed
- Access, including height, roofs and ladders
- A single visit or a regular plan
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. The price is fixed before work begins, and the quote sets out the VAT.
Before you get in touch
What to send for a quote:
- Where the property is and what kind of building it is
- The rating plate or label on any existing unit
- The fuse board and where it is in the property
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To get going, phone us on 07833 053749, or email if that’s easier.
Keeping the system healthy
Systems last better with the right care. We suggest:
- Keep outdoor units clear of rubbish and stored goods
- Involve us at the planning stage of a refurbishment
- Book a maintenance contract to keep servicing on schedule
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions, so you know what’s needed.
Simple control settings help. Units heating and cooling the same space at once is a common problem and correct settings avoid it.
