How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. Before a visit in Ashburton, we ask where the van can stop and how we reach the outdoor unit.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure someone can let us in at the agreed time
- Let us know where we can park and unload

How we handle air conditioning in Ashburton
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, and the manufacturer’s warranty terms are set out on your quote. Looking for air con installers near Ashburton? We’re based in East Grinstead and cover London and the South East, as an F-Gas certified company with NICEIC approval.
Sizing is where cheap installs go wrong: the survey covers room size, glazing, insulation and how the room is used, so the unit isn’t too big or too small.
Space outside is often tight in Ashburton, 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 we plan the pipe route so it’s as short and tidy as the building allows.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

Air conditioning around Ashburton
About 44% of homes in Ashburton and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and the 2021 Census found about 48% of households in terraced houses. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you commute from Norwood Junction station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed. If your home is in one of the older streets near Church of St Luke, it’s worth checking whether it’s listed or in a conservation area before an install.
Ashburton is about 6 miles south of New Cross, in Greater London. Properties in Ashburton get the same service as everywhere we cover: diagnosis first, a fixed price and proper paperwork when we’ve finished. Count every place we list in Greater London and you reach 764, with Ashburton on the list.

How the job changes from property to property
Ducted systems
A ducted system needs a ceiling void or loft deep enough for the unit and ducts plus an access hatch for maintenance. The survey confirms whether there’s room.
Multi-split systems
With a multi-split, one outdoor unit serves two or more rooms. It’s a neat answer when space outside is limited and several rooms need it and each indoor unit has its own controls.
Why it’s worth doing now in Ashburton
The outdoor unit’s position is worth getting right first time. A good position keeps noise down and leaves room for servicing, and it can affect whether planning permission is needed. We agree it with you on the survey. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. You’ll have a fixed price before work begins, with VAT shown clearly.
Why us?
- An F-Gas certified company, as the law requires
- Diagnosis first, then a fixed price
- MCS certified heat pump installers
- Electrical work covered by our NICEIC approval
FAQs for Ashburton
Do I need permission to put air conditioning in my flat in Ashburton?
Often, yes, but the lease and the freeholder usually have a say. 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.
Will air conditioning in Ashburton need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 4 buildings and structures within half a mile of the centre of Ashburton. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Ashburton, typically Croydon council).
Do you provide F-Gas records?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
How long does it take to fit air conditioning?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Do you work in Ashburton?
Yes. Ashburton is part of the area we cover, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Before you call an engineer
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
