Homes in Cootham and air conditioning
Census 2021 figures found about 92% of households in detached or semi-detached houses. Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split.
With historic houses such as Parham House about 1.1 miles west, it’s a reminder that older homes nearby may be listed, which changes the planning rules. A loft bedroom or a glazed extension is often the room that prompts the first call.

Air conditioning for homes and businesses in Cootham
Think of it as diagnose, treat and sign off: 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. Every installation in Cootham begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
Most single-room installs in Cootham are done in a day, while multi-split systems for several rooms can take longer.
Villages like Cootham often have older houses and cottages, some of them listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. Somewhere like Cootham, it helps to know about lanes, gates and where to park.
- You send pictures, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- We protect the area, then fit both halves of the system.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- 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
Getting a quote
Photos are enough for some jobs; others need a visit first. 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.

Why deal with it now?
The best time to plan air conditioning is before the hot weather, not during it. A rushed choice is often the wrong size or in the wrong place, and that is hard to put right later. Booking the survey early gives you time to weigh up the options. A system that’s left with a fault, or without a service, normally costs more to run.
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Common questions in Cootham
Do you cover Cootham for air conditioning?
Yes. Cootham is one of the places we cover. Just ring 07833 053749 or drop us a line with a few details.
Is planning permission needed for air conditioning in Cootham?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Cootham holds about 8 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask Horsham council, which is usually the planning authority for Cootham.
What does it cost to install air conditioning?
For one room, a split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. The price is fixed before work begins.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and AirCon Doctor is certified.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How long does air conditioning installation take?
Allow a day or more, depending on the number of rooms, the pipe routes and the access. The survey tells us how long your installation will need, so you can plan around it.
What you can do yourself, and what needs us
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
System by system
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill and kept as tidy as the building allows.
Outdoor unit positions
The outdoor unit can go on a wall bracket, on the ground or on a flat roof, whatever suits the building and the route. It needs space around it to breathe and for an engineer to work on it.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
