About our air conditioning in Duncton
A single-room split system is typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Supply, installation, commissioning and F-Gas documentation are all included, and commercial VRF systems are priced after a survey. When someone in Duncton asks us for air con, the first questions are usually price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Villages like Duncton often have older houses and cottages, some of them listed. That matters, because a listed home needs consent and permitted development rules do not apply to it.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

What we’re called out for in Duncton
Loft rooms and top floors tend to suffer most. The roof takes the full force of the sun, and warm air rises from the floors below, so a bedroom or office under the roof can stay warm well into the night.
Reasons to give us a call include:
- Working from home in a room that gets too warm
- Old electric heaters you’d like to replace with something more efficient
- Fans and portables that do not keep up
Around Church of Holy Trinity, a quick check of the listing and conservation maps is part of planning any install.
What to look for in a quote
- Whether they looked at the job before pricing it
- Which VAT rate the quote uses, and why
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Owner care supports servicing; it does not replace it. 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.
FAQs for Duncton
Can you do air conditioning in Duncton?
We do: Duncton falls inside our working area. Tell us a little about the job and we’ll take it from there.
Do I need planning permission for air conditioning in Duncton?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 28 buildings and structures within half a mile of the centre of Duncton. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Duncton, usually Chichester council).
How much does air conditioning installation cost?
A single-room split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
Can air conditioning heat my home as well?
Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we’re happy to show ours.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Which type of air conditioning is best?
It depends on the rooms and the building. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. The survey ends with a recommendation and the reasons.

Honest limits
Some problems need a different service or another trade:
- A ventilation problem rather than a temperature problem
- An installation that needs consent nobody has given yet
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
If you are not sure, just phone us on 07833 053749 and we will give you a straight answer before you book.

Air conditioning in Duncton: local notes
VOA council tax data put about 43% of homes in Duncton and the neighbourhoods around it before 1919, and about 73% of households live in detached or semi-detached houses, 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. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Bignor Roman Villa (roughly 2.4 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

How it works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Rural lanes and tight entrances are worth mentioning before a visit to Duncton.
- You send photos, or we visit and survey the rooms and outside.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.

“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.”
