Air conditioning installation in Cassington
For air conditioning in Cassington, one call is all it takes: diagnosis, fixed price, work and sign-off. An F-Gas certified company, NICEIC approved, on Checkatrade.
- An old system that needs replacing
- Not knowing which system, size or brand to choose
- Expensive direct electric heating
Looking after it afterwards
To keep the system working properly:
- Never run the system with the filters out
- Do not cover or box in the outdoor unit
- Avoid setting it far colder than you need
We clear up before we go: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Pipework outside is covered in trunking or insulated and neatly fixed, so the job looks as tidy as it works.
Report drips, noises or error codes early. Water from the indoor unit, a new rattle or a code on the display typically means something needs attention and catching it early keeps the repair small.
Air conditioning for homes and businesses in Cassington
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.

For a home in or near Cassington, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating does not reach well, such as a garden room or loft.

What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes about a day for a single-room system, longer for multi-room and ducted systems. A few pictures help us make the most of a visit to Cassington.
- 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.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Keep pets out of the rooms we are working in
- Clear access to the fuse board

System by system
Multi-split systems
Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The route from the outdoor unit to each room is the main variable.
Electrical supply
We check the consumer unit on the survey, so the quote covers any electrical work needed. An older board may need extra work, and we explain why if so.
Homes in Cassington and air conditioning
Valuation Office Agency council tax records date about 40% of homes in the Cassington area to the post-war years, 1945 to 1972, and about 71% of households live in detached or semi-detached houses, according to Census 2021 figures. We check the wall construction on homes of that age, as it decides how the pipework goes through. Detached and semi-detached houses typically have space for the outdoor unit, and several rooms can share one on a multi-split.
Around Church of St Peter, a quick check of the listing and conservation maps is part of planning any install. Blenheim Palace (roughly 3.4 miles north) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Your questions about air conditioning in Cassington
Is air conditioning in Cassington permitted development?
That depends on the building and where the outdoor unit goes. The Cassington Conservation Area takes in the middle of Cassington. 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 is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with West Oxfordshire council, which is usually the planning authority for Cassington.
Will you come out to Cassington?
Yes. Cassington is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
How soon will you get back to me?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before any work starts, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
How long does air conditioning installation take?
Allow anything from a day for one room to several days for a multi-room or ducted system. We confirm the time when we quote so there are no surprises.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
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.
