Air conditioning in Windsor: the local picture
Central Windsor is inside a conservation area. About 7 listed entries lie within half a mile of central Windsor, St Annes House Convent of St John the Baptist (grade II) among them. That matters for air conditioning: permitted development doesn’t apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling isn’t covered at all, so we check with the local planning authority (typically Windsor and Maidenhead council) where necessary. About 23 miles out from central London, Windsor is part of the South East area we work across.
Living close to All Saints Church? Some older properties in parts like that are protected, and the survey finds out whether yours is.

About our air conditioning in Windsor
Good air conditioning starts with the right system in the right place. Each room is assessed for its size, windows, direction and how it’s used, then agree where the indoor and outdoor units go and how the pipework, cable and condensate drain will run, all before the price is fixed. Need an air conditioning installer for Windsor? We’re based in East Grinstead and cover London and the South East, with a fixed-price quote before any work starts.
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.
Most houses around Windsor have a side or back wall, or a patch of ground, where the outdoor unit can go. The position is chosen with the neighbours’ windows in mind, and the pipework is kept short and tidy, inside through a loft or outside in trunking.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

System by system
Pipework and condensate drains
Cooling produces water as the air is dried, and the condensate drain carries it away. If gravity will not do it, a condensate pump is fitted, and we plan that on the survey.
Wall-mounted split systems
A single-room split is typically £1,200–£2,200 + VAT, with supply, fitting, commissioning and the F-Gas paperwork included. Where you sit in that range depends on the pipe run, access and electrics.
Do you need air conditioning in Windsor?
Everything that uses electricity in a room ends up as heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even on a mild day.
What we’re most often called about:
- Commercial rooms that are too warm for staff
- Fans and portables that don’t keep up
- Uncertainty over the right type and size of system
St Leonard's Hill (roughly 1 mile south-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
Questions to ask before booking
- Whether they hold F-Gas company certification, not just individual qualifications
- Whether the price is fixed or an estimate
- Exactly what the price includes, from supply and fitting to commissioning
FAQs for Windsor
What’s the best way to get a price for air conditioning in Windsor?
The easiest way is to ring 07833 053749 or drop us a line with a few details and photos. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Can you do air conditioning in Windsor?
Yes, Windsor is within the area we cover. To start, give us a ring on 07833 053749 or email us with a few pictures.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
How long does air conditioning installation take?
It takes anything from a day for one room to several days for a multi-room or ducted system. The survey tells us how long your installation will need so there are no surprises.
Can you fit air conditioning in a leasehold flat?
That depends on the lease, the building and where the outdoor unit could go. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
Will skipping a service affect the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them, and book the service at the interval they recommend.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Windsor and across Windsor and Maidenhead. Tell us who should receive the paperwork.
How the visit works
You do not need to do much 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. Before we leave, the area is tidied and we explain what we’ve done. A visit in Windsor is booked for a time that suits you.
- 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.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Getting ready for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure we can reach the consumer unit or fuse board
How to get a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
