Questions from Barnes
Do I need permission to put air conditioning in my flat in Barnes?
Normally, 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 Barnes permitted development?
That depends on the building and where the outdoor unit goes. Central Barnes sits inside the Barnes Green 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 Richmond-Upon-Thames council, normally the authority for Barnes.
How long does air conditioning installation take?
Allow a day or more, depending on the number of rooms, the pipe routes and the access. The survey tells us how long your installation will need so there are no surprises.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Barnes and across Greater London. Tell us who should receive the paperwork.
Do you work in Barnes?
Yes. Our engineers work in Barnes, within the South East and London area we cover. We are based in East Grinstead, West Sussex.
How do you size the system?
We size each room on the survey, from its size, glazing, orientation and use. An undersized unit never catches up, and an oversized one cycles and wastes energy and we explain the output we recommend.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Air conditioning in Barnes
Any installation we do in Barnes follows the same process as everywhere else we work: a site survey, or photos for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. The price is fixed up front and the records are handed over at the end. Most enquiries from Barnes start with one hot room: a bedroom, a home office or a loft conversion. That’s typically a single wall-mounted split, from £1,200 + VAT.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes.
Space outside is often tight in Barnes, as in much of London, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. We look at noise towards neighbours and windows as well as looks, and the pipe run is planned to be short, neat and out of the way.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Avoid setting it far colder than you need
- File the paperwork with the manual
- Do not cover or box in the outdoor unit
We recommend an annual service, and some manufacturers make servicing a warranty condition. We will remind you when it’s due if you’d like.
Clean the filters regularly, not just at the service. Blocked filters cut airflow and make the system work harder, which costs you more to run.
When it’s something else
To be straight with you, there are a few things this work will not fix:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Damp from leaks or a lack of ventilation
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
If you’re not sure, just phone 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll give you a straight answer before you book.
What the work covers
- Multi-split systems
- Ceiling cassettes
- VRF systems
- Wall-mounted split systems
- Air-to-air heat pumps
- Ducted systems
How it works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. The visit takes about a day for a single-room system, longer for multi-room and ducted systems. Let us know who controls access to the building in Barnes, as that saves time on the day.
- 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.
- We protect the area, then fit both halves of the system.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Tell us about parking and loading
- Plan for pets to be kept clear during the visit
- Name a contact who can meet us at the agreed time
Getting a price
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Homes in Barnes and air conditioning
VOA council tax data put about 52% of homes in Barnes and the neighbourhoods around it before 1919, and about 45% of households live in flats, according to the 2021 Census. 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. London installs often hinge on outside space, the lease and access to the building.
Chiswick House, about 0.9 miles north-west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Close to Barnes Bridge station? A small study or box room used for work can usually be cooled with a single indoor unit.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
From one of our customers
“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.”
