About our air conditioning in Hornsey
Any installation we do in Hornsey follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. You know the price before work begins and the paperwork is in your hands when we finish. A lot of the calls we get from Hornsey are about one room that is too hot to sleep or work in. That is usually a single wall-mounted split, from £1,200 + VAT.
London homes in Hornsey can be short of outside space, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. Neighbours’ windows and noise matter as much as appearance when we choose the position, and the pipe run is planned to be short, neat and out of the way.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

Landlords, agents and facilities managers
If you look after several properties, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so each one has its own history.
Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Fixed-price quotes for air conditioning in Hornsey
Our prices page gives typical ranges, and your quote is built on your job. What we look at:
- The equipment or parts the job needs
- Access, including height, roofs and ladders
- What electrical work the job needs
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed price.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The postcode and whether it’s a home, flat or business
- A short video of any fault, such as a noise or a flashing light
- Your consumer unit or fuse board
Here’s what helps us quote: where the property is and what kind of building it is, photos of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then call us on 07833 053749 or fill in the contact form.

Questions from Hornsey
Will air conditioning in Hornsey need planning permission?
That depends on the building and where the outdoor unit goes. The centre of Hornsey is in the Hillfield 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 needed, we check with Haringey council, which is normally the planning authority for Hornsey.
Do you cover Hornsey for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Hornsey is part of that. To start, ring 07833 053749 or send an email with a few photos.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Hornsey and across Greater London. Let us know who the records should go to.
Which type of system should I choose?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Where will you put the outdoor unit?
It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours and position can affect planning.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.
The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. The more we can see beforehand, the smoother the visit to Hornsey will be.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Have the make and model of any existing unit to hand
- Let us know if the units are on a roof, a high wall or in a locked area
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
What an install looks like in Hornsey
About 63% of homes in and around Hornsey were built before 1919, according to Valuation Office Agency council tax records, and about 70% of households live in flats, according to Census 2021 figures. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder typically decide where an outdoor unit can go, and the permitted development rules for flats are tighter. London installs often hinge on outside space, the lease and access to the building.
Close to Hornsey station? A small study or box room used for work can normally be cooled with a single indoor unit. Bruce Castle, about 2 miles north-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

What owners can safely do
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
