Air conditioning installation in West Thorney
Any installation we do in West Thorney follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. You know the price before we start and the paperwork is in your hands when we finish. Every installation in West Thorney begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
In a village like West Thorney, many homes are older, and some are listed. We check that first, because permitted development does not apply within the grounds of a listed building.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

What we do, step by step
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 anything from a day for one room to several days for a multi-room or ducted system. Rural lanes and tight entrances are worth mentioning before a visit to West Thorney.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any roof access, ladders or high-level work

Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Advice
Homes in West Thorney and air conditioning
The coast is only about 1 mile from West Thorney. Salt air is hard on outdoor units, so we site them out of the worst of the sea wind where we can, and can suggest models with corrosion-protected coils where the manufacturer offers them. About 70% of households live in detached or semi-detached houses, according to the last census (2021). 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.
Homes near The Parish Church of St Nicholas are a good example of where we look up the heritage status of the building before fixing anything to it. Warblington Castle (roughly 3.1 miles north-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Questions from West Thorney
Is the coast a problem for outdoor units in West Thorney?
It can. West Thorney is within about 1 mile of the coast, and salt air speeds up corrosion on outdoor units. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Will you come out to West Thorney?
Yes. West Thorney is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Is air conditioning possible in a flat?
Often, yes, but there are extra steps. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls and the lease will say. Permitted development rules for flats are also tighter than for houses, and we flag anything that may need permission. This is general information, not legal advice.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Which type of air conditioning is best?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
What air conditioning cannot fix
Before booking, it helps to know what’s not included:
- A ventilation problem rather than a temperature problem
- Building damp that has a structural cause
- Work that needs permission from a landlord or the council
Not sure which it is? You can phone 07833 053749, or email if that’s easier and we’ll tell you honestly.

Safe owner checks
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.

Aftercare tips
Looking after it is simple, and it helps at the next service:
- Keep the room closed while it runs
- Flag any change in how the system sounds or performs
- Keep the outdoor unit clear of leaves, plants and clutter
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Outside, the pipework is neatly fixed and protected, so the job looks as tidy as it works.
Have the system serviced once a year. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early and keeps the warranty paperwork right where servicing is a condition.
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.”
