Air conditioning installation in Nash
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. We recommend a model on the survey and explain why it suits the room, and the manufacturer’s warranty terms are set out on your quote. When someone in Nash asks us for air con, the first questions are usually price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
Planning permission is not normally needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats need more care: we tell you at the survey if it applies.
Space outside is often tight in Nash, as in much of London, 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.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Your questions about air conditioning in Nash
Can you do air conditioning in Nash?
Yes, Nash is within the area we cover. Get in touch with the details and we reply the same working day.
Do I need permission to put air conditioning in my flat in Nash?
Usually, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can you fit air conditioning in a leasehold flat?
Often, yes, but there are extra steps. You will typically need the landlord’s or management company’s consent for the outdoor unit and the pipe route and the lease will say. Planning rules for flats are tighter too, so we point out anything that may need permission on the survey. This is general information, not legal advice.
Where does the outdoor unit go?
Wall brackets, ground level and flat roofs are all options, chosen for the pipe route, airflow and access. Noise near bedrooms and boundaries is part of the decision, and the position can affect planning.
How do you keep the place clean during the work?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do I need to service the system to keep the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.

How the visit works
Each visit follows the same order: check the plan with you, protect the area, carry out the job, test what we’ve done and explain it all to you. On site, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Send us a few phone photos and we can often price a straightforward job in Nash before visiting.
- We survey the property, or work from your photos for a simple job.

Signs you need air conditioning in Nash
Computers, screens, lighting and people all give off heat. A small office or a busy room can warm up fast with equipment and people in it, even when it isn’t especially hot outside.
Customers usually contact us after spotting one of these:
- An ageing air conditioning system near the end of its life
- Commercial rooms that are too warm for staff
- A room that’s unbearable on warm days
If your home is in one of the older streets near Keston Parish Church, it’s worth checking whether it’s listed or in a conservation area before an install.
Questions to ask before you book
- The make and model of any parts or equipment being quoted
- Proof of F-Gas company certification
- Exactly what the price includes, from supply and fitting to commissioning
What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Homes in Nash and air conditioning
About 69% of homes across Nash and its surrounding area were built between the wars, according to Valuation Office Agency council tax records, and the 2021 Census found about 78% of households in detached or semi-detached houses. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Down House, about 2.4 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Nash is about 3 miles south of Bromley, in Greater London. Whether you’re in the middle of Nash or further out, our engineers cover air conditioning, from a single room to a whole building. In Greater London alone we list 764 places, and Nash is one.

What air conditioning will not do
Not every problem is solved by air conditioning, and we’d rather say so up front. It will not put right:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Gas boiler or central heating faults (we don’t work on gas boilers)
- Work that needs permission from a landlord or the council
Not sure which it is? You can ring 07833 053749 or email us and we will tell you honestly.

“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.”
