How we handle air conditioning in Cholsey
Thinking about air conditioning but not sure where to start? Send a few pictures of the rooms and the outside walls when you phone us on 07833 053749 or drop us a line, and you’ll hear back from us the same working day about a survey or a fixed-price quote. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Oxfordshire.
Where the outdoor unit goes decides how quiet and tidy the job is: airflow, noise towards neighbours, pipe length and access for servicing all count.
A cottage and a newer house near Cholsey are very different jobs. Thick walls, low ceilings and beams need care with pipe routes, and a listed home needs consent before anything is fixed to it.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Owner checks or an engineer?
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and give us a ring on 07833 053749 or fill in the contact form.
System by system
Multi-split systems
You can mix indoor unit types on many multi-split systems, choosing what suits each room, as the manufacturer allows. We plan the mix on the survey.
Offices, shops and commercial rooms
Commercial rooms often need more than one unit and controls that suit how the space is used. Sizing takes account of occupants, equipment and windows and we plan the installation around your opening hours where we can.
What we’re called out for in Cholsey
Rooms in the roof are often the hardest to keep cool. The roof takes the full force of the sun, and warm air rises from the floors below, which is why a loft bedroom can still be warm at bedtime.
These are the situations we see most often:
- Too many options and no clear advice
- Rooms under the roof that stay hot into the night
- A study or office that overheats during the day
Brightwell Manor, about 2.9 miles north, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Before you book anyone
- Whether anyone has checked the property or the system first
- Whether you get F-Gas records where refrigerant is involved
- Why the equipment they’re quoting suits the job

What else we do in Cholsey
What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. A few pictures let us plan a visit to a place like Cholsey.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Let us know if the building has a permit or sign-in process
- Tell us about parking and loading
- Have the make and model of any existing unit to hand

Air conditioning in Cholsey: the local picture
About 42% of homes in Cholsey and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and about 72% of households live in detached or semi-detached houses, according to Census 2021 figures. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
If you commute from Cholsey station and work from home on other days, one wall-mounted unit in the home office is often all that is needed.

Common questions in Cholsey
Is Cholsey within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Will air conditioning in Cholsey need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 27 buildings and structures within half a mile of the centre of Cholsey. 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 South Oxfordshire council, usually the authority for Cholsey.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
What does it cost to install air conditioning?
Single-room systems start from £1,200 + VAT and are typically up to £2,200 + VAT. The price includes supply, installation, commissioning and F-Gas documentation, and we fix it after a survey or from your photos.
Does air conditioning need its own electrical supply?
Usually, yes. We check your consumer unit on the survey and include any electrical work on the quote, and our NICEIC approval covers the installation and certificate.
When will I hear back?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
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.”
