Fontwell air conditioning
We cover Fontwell for supply, installation and commissioning of air conditioning for homes and businesses, from one room to a whole building. A look at the job first, a fixed-price quote and written records at the end.

- Commercial rooms that are too warm for staff
Air conditioning in Fontwell, done properly
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, along with the manufacturer’s warranty terms on your quote. Most enquiries from Fontwell start with one hot room: a bedroom, a home office or a loft conversion. A single-room split system is often the answer, from £1,200 + VAT.
Sizing is where cheap installs go wrong: we look at the room’s size, windows, insulation and use before choosing a unit.
Space outside is rarely the problem in a place like Fontwell. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
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 every service is written up.

How the visit works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes anything from a day for one room to several days for a multi-room or ducted system. Pictures of the space and where the outdoor unit could go let us plan the work in Fontwell.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- 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.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Keep pets out of the rooms we are working in
- Make sure we can reach the outdoor unit, or where it will go
- Mention any parking restrictions near the property
How to get a quote
Here’s what helps us quote: where the property is and what kind of building it is, pictures of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Then phone 07833 053749 or drop us a line.

Fontwell: your questions answered
Is air conditioning in Fontwell permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 4 buildings and structures within half a mile of the centre of Fontwell. 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 isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the local planning authority (for Fontwell, normally Arun council).
Is Fontwell within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
What does it cost to install air conditioning?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork and is fixed after a survey or from pictures.
Can I have air conditioning in a flat?
Often, yes, but there are extra steps. You will typically need the landlord’s or management company’s consent for the outdoor unit and the pipe route, so check the lease. Permitted development rules for flats are also tighter than for houses, so we point out anything that may need permission on the survey. 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 yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Does air conditioning need its own electrical supply?
Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we install and certify it as part of the job.

Why act early in Fontwell
The outdoor unit’s position is worth getting right first time. A good position keeps noise down and leaves room for servicing, and it can affect whether planning permission is needed. We agree it with you on the survey. Planning ahead for a job in Fontwell means we can bring everything needed.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, ring 07833 053749 or email us for straight advice and a fixed price.

Air conditioning in Fontwell: local notes
About 35% of homes across Fontwell and its surrounding area have been built since 2000, according to VOA council tax data, and Census 2021 figures found about 71% 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.
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed.

What we’re called out for in Fontwell
Not everyone is after cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, which means more heat out than electricity in. That is how most modern split systems work.
Reasons to give us a call include:
- An old system that needs replacing
- A loft room or top floor that bakes in summer
- Working from home in a room that gets too warm
Goodwood House (roughly 4.2 miles west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
What your quote should include
- Whether anyone has checked the property or the system first
- What the manufacturer’s warranty covers and for how long
- Whether a new circuit is included and who certifies it
Let and managed properties
