Air conditioning for homes and businesses in Wonersh
Any installation we do in Wonersh follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. Air conditioning installation in Wonersh starts with a site survey, then a fixed-price quote that names the make and model.
Homes around Wonersh usually have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

How we price air conditioning
The survey or diagnosis tells us what the work involves. The main factors are:
- Whether the existing supply is suitable
- The equipment or parts the job needs
- What kind of system it is
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
To help us quote quickly, send us:
- Your installation or service records
- A photo of the consumer unit with the cover closed
- The make and model of the system, from the label
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price so you know the cost before we begin.
Questions from Wonersh
Is Wonersh within the area you cover?
Yes. Wonersh is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Do you cover Wonersh for air conditioning?
We do: Wonersh falls inside our working area. Tell us a little about the job and we’ll take it from there.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do I need a new electrical circuit?
Normally, 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.
Is planning permission needed for the outdoor unit?
Not necessarily. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas, and we tell you at the survey. This is general information, not legal advice.
How much is air conditioning for one room?
Single-room systems start from £1,200 + VAT and are typically up to £2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork and is fixed after a survey or from photos.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Aftercare tips
How well a system lasts depends on use and care. Here’s what we suggest:
- Shut doors and windows when it’s on
- Keep the handover documents somewhere safe
- Keep the outdoor unit clear of leaves, plants and clutter
Commissioning is the last stage: every mode is tested before we go. We check it’s running as the manufacturer intends, then show you the controls and the timer, so you are confident using it.
Have the system serviced once a year. A service cleans what you cannot reach and picks up faults before they stop the system, and it keeps any warranty servicing conditions in order.
What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. The middle part takes longest, and that takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Photos of the existing unit help with repairs and servicing in Wonersh.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Arrange for someone to be there to let us in
- Unlock any gate, garage or side passage we need
- Dig out any previous service or F-Gas records

Air conditioning in Wonersh: the local picture
Wonersh’s centre is no more than about a third of a mile from the Wonersh Conservation Area. There are 2 conservation areas within a mile of the centre of Wonersh. Historic England lists about 36 buildings and structures within half a mile of the centre of Wonersh, including The Dower House (grade II*). None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit. About 78% of households live in detached or semi-detached houses, according to Census 2021 figures. 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.
About 1.7 miles north stands Chilworth Manor. Listed homes in any area need consent first, so tell us if yours is one. Around Wonersh United Reformed Church, a quick check of the listing and conservation maps is part of planning any install.
