Homes in Sunninghill and air conditioning
About 30% of homes in the Sunninghill area have been built since 2000, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 66% of households in detached or semi-detached houses. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. 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.
Around Church of St Michael and All Angels, a quick check of the listing and conservation maps is part of planning any install. With historic houses such as St Leonard's Hill about 4.6 miles north, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Air conditioning in Sunninghill, done properly
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, along with the manufacturer’s warranty terms on your quote. Air con, air conditioning, a split system: whatever you call it, in Sunninghill it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
The electrics are part of the job: a dedicated circuit where the unit needs one, certified under NICEIC, so the electrical paperwork comes with the installation.
Outdoor units around Sunninghill often sit on the ground or a low wall bracket at the back of the house, where it’s tucked away but still easy to reach for servicing.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes anything from a day for one room to several days for a multi-room or ducted system. Tell us about any gates or steps at your property near Sunninghill when you book.
- First comes a site survey, or photos and measurements for a straightforward job.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
How to prepare
- Have the make and model of any existing unit to hand
- Make sure we can reach the consumer unit or fuse board
- Name a contact who can meet us at the agreed time
Ask for a quote
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.
Advice
After we have gone
So the system stays in good health:
- Shut doors and windows when it’s on
- Keep the indoor unit’s filters clean
- Choose a comfortable set temperature rather than the lowest
We clear up before we go: sheets removed, packaging cleared up and pipe holes sealed. Pipework outside is covered in trunking or insulated and neatly fixed, so the job looks as tidy as it works.
Keep the outdoor unit clear. Leaves, plants, bins and stored items around it restrict the airflow, and the system has to work harder as a result.
What air conditioning will not do
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Stuffy rooms that need fresh air rather than cooling
- Work that needs permission from a landlord or the council
- Damp from leaks or a lack of ventilation
If you are not sure, just phone us on 07833 053749 and we will give you a straight answer before booking.

Sunninghill: your questions answered
Do you cover Sunninghill for air conditioning?
Yes. Sunninghill is one of the places we cover. Just ring us on 07833 053749 or drop us a line with a few details.
Is air conditioning in Sunninghill permitted development?
It depends on the property. A conservation area takes in the middle of Sunninghill. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the local planning authority (for Sunninghill, normally Windsor and Maidenhead council).
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
What size air conditioning unit do I need?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count and the survey covers each of them.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Will you need to do electrical work?
Most systems need their own supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we install and certify it as part of the job.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
For landlords and property managers
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We can quote either party and send the records to whoever needs them.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
