Air con installers in Hendon
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be and we talk you through it on the survey. Looking for air con installers near Hendon? AirCon Doctor works across London and the South East from East Grinstead, as an F-Gas certified company with NICEIC approval.
Across London, and in Hendon too, a lot of air conditioning goes into flats and terraces rather than detached houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder usually come into it, and we can give you the details they’ll ask for.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

What affects the quote in Hendon
Jobs vary more than people expect. What affects the quote:
- The type of system, from a single split to a larger system
- The number of rooms, units or zones
- What electrical work the job needs
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account, and the price is fixed before we start.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Where the outdoor unit is, or where you’d like it
- The fuse board and where it is in the property
- A few pictures of the room and the wall the unit is on, or will go on
Photos are enough for some jobs; others need a visit first. 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.
After we’ve gone
A little care keeps the system in better shape. Our advice:
- Keep the handover documents somewhere safe
- Do not cover or box in the outdoor unit
- Flag any change in how the system sounds or performs
We clear up before we go: sheets removed, packaging cleared up and pipe holes sealed. Outside, the pipework is neatly fixed and protected as agreed on the survey.
Don’t ignore small changes. Water from the indoor unit, a new rattle or a code on the display typically means something needs attention and catching it early keeps the repair small.
What an install looks like in Hendon
The Valuation Office Agency’s council tax figures show about 45% of homes in Hendon and the neighbourhoods around it date from 1919 to 1939, and about 59% of households live in flats, according to the 2021 Census. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
Plenty of people near Hendon station split the week between the train and a spare room, and that spare room is often the first to get a unit.

What we’re called out for in Hendon
Rooms overheat mostly because of heat they gain during the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and once the room has warmed up, it holds on to it into the evening.
Reasons to give us a call include:
- Portable units that are noisy and barely cope
- Old electric heaters you’d like to replace with something more efficient
- A loft conversion that’s too warm to use
With historic houses such as Heath Hall about 2.3 miles east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Hendon: your questions answered
Is Hendon in your area for air conditioning?
Yes. Hendon is one of the places we cover. Get in touch with the details and we reply the same working day.
Is planning permission needed for air conditioning in Hendon?
It comes down to the building and the spot chosen for the outdoor unit. Around 19 listed entries sit within 0.5 miles of central Hendon. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask Barnet council, which is typically the planning authority for Hendon.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Where does the outdoor unit go?
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. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to 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 Hendon
What happens on the day
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 don’t need a separate electrician for the electrical side. The work takes a day or more, depending on the number of rooms, the pipe routes and the access. For a job in Hendon, tell us about parking, permits and access to the building when you get in touch.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
