How the job changes from property to property
Pipework and condensate drains
We pressure test and evacuate the pipework before the system is charged, so the system starts life clean, dry and leak-tight. It’s recorded in the commissioning details.
Electrical supply
We check the consumer unit on the survey, so any extra electrical work is on the quote rather than a surprise on the day. An older board may need extra work and we’ll tell you if yours does.
Air conditioning in Wisley, done properly
A single-room split system is typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £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, with commercial and VRF systems priced after a survey. Modern air conditioning heats as well as cools: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, which is why many owners use theirs all year.
Sizing is where cheap installs go wrong: the survey covers room size, glazing, insulation and how the room is used, so the unit isn’t too big or too small.
In a village like Wisley, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules don’t apply to it, and the outdoor unit position is chosen to suit the building.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Air conditioning around Wisley
In the mile around Wisley’s centre, 3 conservation areas have been designated. Church (dedication Unknown), listed at grade I, is one of roughly 4 protected buildings and structures in the half-mile around Wisley’s centre. Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, the planning team at Guildford council, which normally handles Wisley has the final say on what’s allowed. VOA council tax data date about 41% of homes in and around Wisley to the post-war years, 1945 to 1972. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route.
Older streets near Wisley Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. About 0.8 miles north-east stands Byfleet Manor. Listed homes in any area need consent first, so tell us if yours is one.
Wisley is about 4 miles south of Weybridge, in Surrey. Whatever kind of property you have in Wisley, our engineers can help with air conditioning.

Our nearest recent job to Wisley was on Between Streets, Cobham (KT11), about 4 miles east: installing a Mitsubishi Electric multi-split system in the main house: covering four bedrooms and the kitchen-living area: and a separate split system in the annexe, which is used as a home office and guest accommodation.

What happens on the day
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. If a lane or gateway near Wisley is tight for a van, let us know and we will plan for it.
- 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.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Keep pets out of the rooms we’re working in

What else we do in Wisley
What owners can safely do
Some faults have simple causes you can check first: 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 phone 07833 053749 or fill in the contact form.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Why act early in Wisley
A system that’s the wrong size never works well. Too small, and it runs flat out without catching up; an oversized one cycles on and off and wastes energy. Sizing each room properly on the survey avoids both. A dirty or faulty system works harder and costs more to run.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you’ll get one fixed price.

Questions from Wisley
Do you cover Wisley for air conditioning?
We do: Wisley falls inside our working area. Tell us a little about the job and we will take it from there.
Is Wisley within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Should I choose wall-mounted, ducted or cassette?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How do you size the system?
Sizing is done on the survey, room by room. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
Can you fit air conditioning in a leasehold flat?
In many cases, but permissions come first. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls and the lease will say. Planning rules for flats are tighter too, and we flag anything that may need permission. This is general information, not legal advice.
A customer’s words
“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.”
