What the work involves, system by system
Ducted systems
Ducted air conditioning hides the indoor unit in a ceiling void or loft, and all you see is a discreet grille. It suits rooms where a visible unit wouldn’t work.
Ceiling cassettes
For wide rooms, a cassette spreads the air more evenly than one wall unit with just a grille visible in the ceiling.
Air conditioning for homes and businesses in Nunhead
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger 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. Every installation in Nunhead begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
Most single-room installs in Nunhead are done in a day, with multi-room systems taking longer depending on pipe routes.
In a London area like Nunhead, many of the homes we’re asked about are flats, maisonettes and terraced 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 typically come into it, so we write up the proposed positions for them to see.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Questions from Nunhead
Can you fit air conditioning in a London flat in Nunhead?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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.
Is air conditioning in Nunhead permitted development?
The answer turns on the property and where the outdoor unit would sit. Central Nunhead sits inside the Nunhead Cemetery Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Lewisham council, typically the authority for Nunhead.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
What size air conditioning unit do I need?
Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it and the survey covers each of them.
Will skipping a service affect the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Managing agents and facilities teams in Nunhead
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
Records are where property maintenance often slips. Every visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.

Other services in Nunhead
Do you need air conditioning in Nunhead?
Commercial spaces gain heat from people, equipment, lighting and glazing. Keeping staff and customers comfortable is normally what prompts the call, and some rooms need cooling for the equipment as much as the people.
If any of these sounds familiar, it’s worth a diagnosis:
- A business premises that overheats in summer
- A portable unit with a hose out of the window
- Uncertainty over the right type and size of system
If you work from home near Nunhead station, a home office that overheats is one of the easiest rooms to cool.
What your quote should include
- Whether a new circuit is included and who certifies it
- Which VAT rate the quote uses, and why
- How extra work would be agreed if they find something unexpected
How it works
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 about a day for a single-room system, longer for multi-room and ducted systems. Pictures of the space and the outside wall help us plan the work in Nunhead.
- We survey the property, or work from your pictures for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- It’s switched on, checked and handed over with its records.
Before we arrive
- Keep pets and children away from the work area
- Find the manual or the paperwork for the system, if you have it
- Let us know where we can park and unload
Get a fixed-price quote
Some jobs can be priced from photos, 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.

Homes in Nunhead and air conditioning
Valuation Office Agency council tax records put about 47% of homes in the Nunhead area before 1919, and the 2021 Census found about 62% of households live in flats. 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. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Older streets near Saint Antony with Saint Silas may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
