Air con installers in Catherington
We approach an installation much as a doctor approaches a patient: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. When someone in Catherington asks us for air con, the first questions are typically price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Planning permission isn’t typically needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
Around Catherington, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Common questions in Catherington
Will air conditioning in Catherington need planning permission?
It depends on the property. There’s a conservation area, the Catherington Conservation Area, close to central Catherington. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact East Hampshire council, which is normally the planning authority for Catherington.
Can you do air conditioning in Catherington?
Yes. We work across London and the South East from our base in East Grinstead, and Catherington is part of that. Tell us a little about the job and we will take it from there.
Can you fit air conditioning in a leasehold flat?
That depends on the lease, the building and where the outdoor unit could go. Balconies, flat roofs and rear walls can all work, subject to consent, and we check the options on the survey. This is general information, not legal advice.
Does air conditioning work as heating?
Typically, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: a look first, a fixed-price quote and written records.
How long does it take to fit air conditioning?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a village like Catherington, tell us about narrow lanes, gates and parking when you book.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- It’s switched on, checked and handed over with its records.
Before we arrive
- Move furniture away from the wall where we will be working
- Let us know if the units are on a roof, a high wall or in a locked area
- Have the make and model of any existing unit to hand
Getting a price
The quickest way to a quote is to send pictures: 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 many jobs can be priced from that.

Why act early in Catherington
New systems now use lower-impact refrigerants. From 2025, single splits under 3 kg can’t use refrigerants with a GWP over 750, so new splits use refrigerants such as R32, with a GWP of 675. R410A, used in many older systems, has a GWP of 2088. Booking before summer means the work in Catherington is done before the hot weather.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, call 07833 053749 or use the quote form for straight advice and a fixed price.
