Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call 07833 053749 or write to us at info@aircondoctor.co.uk.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Air conditioning in Highgate, done properly
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and our NICEIC approval means we install and certify it ourselves. People searching for “air con near me” in Highgate want two things: a sensible price and someone qualified. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
London homes in Highgate can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. 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, because it helps with any later warranty question.

FAQs for Highgate
Can you fit air conditioning in a London flat in Highgate?
Often, yes, but the lease and the freeholder usually have a say. 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.
Do I need planning permission for air conditioning in Highgate?
The answer turns on the property and where the outdoor unit would sit. The centre of Highgate is in the Highgate Conservation Area. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the planning department at Haringey council, normally the authority for Highgate.
How long does it take to fit air conditioning?
A single-room system is normally fitted in a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Is Highgate in your area?
Yes. We work in Highgate and the rest of Greater London, as part of our area across London and the South East. To book, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Can I use air conditioning to heat a room?
Typically, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Which type of system should I choose?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What happens if it’s left?
For a home or business in Highgate, booking the survey now gives time to plan. The installation takes about a day for a single-room system, longer for multi-room and ducted systems, and we agree a date that suits you after you’ve accepted the fixed price. Approvals for flats in Highgate can take longer than the install itself.
What you pay depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before we start, so there are no surprises.

The process
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and the outside wall help us plan the work in Highgate.
- We survey the property, or work from your pictures for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Mention any roof access, ladders or high-level work
- Move furniture away from the wall where we’ll be working
- Have the make and model of any existing unit to hand
How to get a quote
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 pictures or on a survey, you get a fixed price. To start, call us on 07833 053749, or email if that’s easier.

Do you need air conditioning in Highgate?
Not everyone is after cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, which means more heat out than electricity in. That’s how most modern split systems work.
Look out for these signs:
- An ageing air conditioning system near the end of its life
- A loft conversion that is too warm to use
- A home office that warms up with screens and equipment
Older streets near Highgate United Reformed Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.

Air conditioning in Highgate: local notes
The Valuation Office Agency’s council tax figures put about 48% of homes across Highgate and its surrounding area before 1919, and the 2021 Census found about 74% of households live in flats. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
With historic houses such as Witanhurst about 0.4 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
