Fixed-price quotes for commercial air conditioning in Islington
We quote each job individually. These are the things that affect it:
- Whether it’s a simple split or a larger system
- The distance and route between the indoor and outdoor units
- The electrical supply and whether a new circuit is needed
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed price.
Helping us quote
There’s no need for technical detail. Just send:
- The paperwork from the last service, if you have it
- The fuse board and where it is in the property
- Any error code or flashing light on the display
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone 07833 053749, or email if that’s easier.
About our commercial air conditioning in Islington
The right system depends on the building. Wall-mounted splits suit small offices and single rooms, cassettes suit open ceilings, ducted units hide away in ceiling voids, and VRF or VRV serves many rooms from shared outdoor units. We explain the options and why we’d choose one over another. The work covers VRF systems, multi-split systems and ducted systems, and people most often call us about older systems on refrigerants that are getting scarcer and staff complaining about the temperature.
For a business in Islington, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the F-gas records and flag what’s coming up.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Cooling for Islington businesses
Food Standards Agency data counts about 2,021 restaurants, cafés and canteens, about 100 hotels, B&Bs and guest houses and about 70 schools and colleges in and around Islington, up to about a mile and a half out. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. About 49% of homes in Islington and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 80% of households live in flats. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. For London businesses, plant position, noise and access are planned with the building first.
Offices near Essex Road station often need cooling for meeting rooms and server cupboards as well as the main space.

Before you call an engineer
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Parking bays, permits and roof or balcony access are the first things we ask about in Islington.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
How to prepare
- Clear access to the fuse board
- Move furniture away from the wall where we’ll be working
- Find the manual or the paperwork for the system, if you have it

FAQs for Islington
Do you cover Islington for commercial air conditioning?
Yes, Islington is within the area we cover. To start, call 07833 053749 or use the quote form with a few photos.
Is air conditioning in Islington permitted development?
The answer turns on the property and where the outdoor unit would sit. The centre of Islington is in a conservation area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Islington, usually Islington council).
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Do I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
Can you work around our opening hours?
We can. Work can be scheduled around your hours, including phased work floor by floor.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
