Air conditioning for homes and businesses in Dorney
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be and we talk you through it on the survey. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
In a village like Dorney, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it, and the outdoor unit position is chosen to suit the building.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

What happens if it’s left?
Size matters more than brand. An undersized unit runs hard and still cannot keep the room cool; an oversized one cycles on and off and wastes energy. Sizing each room properly on the survey avoids both. Dealing with it now is typically simpler than a breakdown later.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we will go through it with you.

Air conditioning in Dorney: local notes
VOA council tax data show about 30% of homes in the Dorney area date from 1919 to 1939. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route.
If your home is in one of the older streets near Church of St James, it’s worth checking whether it’s listed or in a conservation area before an install.

Pricing air conditioning in Dorney
Every job gets its own quote. This is what makes a difference:
- Access, including height, roofs and ladders
- The pipe route between the units
- The brand, model and parts involved
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.
Before you get in touch
There’s no need for technical detail. It helps if you can send:
- The paperwork from the last service, if you have it
- A few photos of the room and the wall the unit is on, or will go on
- The outside wall, roof or yard where the outdoor unit sits or would go
For a fixed-price quote, call 07833 053749 or email us and tell us about the property and what you need. Photos help a lot. We reply to enquiries the same working day.
The process
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. All told, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. Visits to Dorney are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We survey the property, or work from your photos for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- We protect the area, then fit both halves of the system.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Preparing for the visit
- Let us know where we can park and unload
- Mention any roof access, ladders or high-level work
- Let us know if the building has a permit or sign-in process

Your questions about air conditioning in Dorney
Do you cover smaller places like Dorney?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Can I fit air conditioning in Dorney without planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Dorney is a short walk from the Dorney Conservation Area. 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 planning department at Buckinghamshire council, usually the authority for Dorney.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Should I choose wall-mounted, ducted or cassette?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
How much is air conditioning for one room?
For one room, a 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. The price is fixed before we start.
