Air con installers in Grange Mills
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Whether you call it air con, air conditioning or an air-to-air heat pump, in Grange Mills it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
A typical install in Grange Mills is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
London homes in Grange Mills 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 we plan the pipe route so it’s as short and tidy as the building allows.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Grange Mills: your questions answered
Is Grange Mills in your area for air conditioning?
Yes. Grange Mills 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 Grange Mills?
It comes down to the building and the spot chosen for the outdoor unit. Central Grange Mills is a short walk from the La Retraite Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Grange Mills, typically Wandsworth council) when it matters.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Grange Mills and across Greater London. Tell us who should receive the paperwork.
How long will the installation take?
Allow anything from a day for one room to several days for a multi-room or ducted system. The survey tells us how long your installation will need so there are no surprises.
How the job changes from property to property
Ducted systems
With a ducted system, the indoor unit sits out of sight above the ceiling, and all you see is a discreet grille. It suits rooms where a visible unit wouldn’t work.
Outdoor unit positions
The outdoor unit can go on a wall bracket, on the ground or on a flat roof, depending on the property and the pipe route. It needs airflow around it and room for servicing.
What air conditioning won’t do
Some problems need a different service or another trade:
- Draughts and missing insulation
- Gas boiler or central heating faults (we don’t work on gas boilers)
- An installation that needs consent nobody has given yet
If you are not sure, just give us a ring on 07833 053749 or drop us a line and we’ll give you a straight answer.

What an install looks like in Grange Mills
About 55% of homes in the Grange Mills area were built before 1919, according to Valuation Office Agency council tax records, and the last census (2021) found about 71% 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. 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.
Close to Balham station? A small study or box room used for work can usually be cooled with a single indoor unit. Kingswood House (roughly 2.9 miles east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

How the visit works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. Parking bays, permits and roof or balcony access are the first things we ask about in Grange Mills.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- 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.
Before we arrive
- Arrange for someone to be there to let us in
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the outdoor unit, or where it will go

Rented and managed buildings
Whether it’s one property or many, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.

“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.”
