System by system
Wall-mounted split systems
Single-room split systems are typically £1,200–£2,200 + VAT, including supply, installation, commissioning and F-Gas documentation. Where you sit in that range depends on the pipe run, access and electrics.
Electrical supply
The fuse board is looked at during the survey, so the quote covers any electrical work needed. Older boards sometimes need more work to take a new circuit, and we explain why if so.
How we handle air conditioning in Preston Crowmarsh
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. We recommend a model on the survey and explain why it suits the room, along with the manufacturer’s warranty terms on your quote. Most split systems we fit in Preston Crowmarsh are reversible: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
For a home in or near Preston Crowmarsh, an air-to-air system can cool in summer and heat in the cooler months, which suits garden rooms, lofts and extensions that the main heating struggles with.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

How it works
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. Photos of the room and the outside of the property help us plan a visit to Preston Crowmarsh.
- 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.
- 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
- Clear access to the fuse board
- Plan for pets to be kept clear during the visit
- Arrange for someone to be there to let us in
How to get a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
Preston Crowmarsh: your questions answered
Can you do air conditioning in Preston Crowmarsh?
Yes. We work across London and the South East from our base in East Grinstead, and Preston Crowmarsh is part of that. Tell us a little about the job and we will take it from there.
Will you come out to Preston Crowmarsh?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
How long will the installation take?
It takes about a day for a single-room system, longer for multi-room and ducted systems. We confirm the time when we quote so there are no surprises.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. An undersized unit never catches up, and an oversized one cycles and wastes energy, so we explain why we’ve chosen a particular output.
For landlords and property managers
If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so each one has its own history.
We also work for facilities teams in offices, schools and public buildings in Preston Crowmarsh and across Oxfordshire. Larger buildings can be done in stages around the people who use them.
Air conditioning in Preston Crowmarsh: the local picture
Preston Crowmarsh’s centre falls inside the Preston Crowmarsh Conservation Area. 3 conservation areas lie within a mile of central Preston Crowmarsh. Listed buildings are part of the picture here: about 16 within half a mile of the centre, such as Church of St Helen (grade II*). Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, South Oxfordshire council, typically the planning authority here has the final say on what’s allowed. About 30% of homes in and around Preston Crowmarsh have been built since 2000, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 77% 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.
Living close to Church of St Helen? Some older properties in parts like that are protected, and the survey finds out whether yours is.

Do you need air conditioning in Preston Crowmarsh?
Not everyone is after cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, so it gives out more heat than the electricity it uses. That is how most modern split systems work.
What we’re most often called about:
- Portable units that are noisy and barely cope
- Bedrooms and offices that overheat in summer
- A business premises that overheats in summer
With historic houses such as Brightwell Manor about 2.4 miles west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
