Crawley's mix of housing stock throws up some real variety when it comes to air conditioning work. You've got the older terraces around Three Bridges and West Green with narrower cavity walls and trickier pipe runs, newer estates out towards Bewbush and Tilgate with more straightforward stud partitions for a wall-mounted unit, and a fair number of offices and light industrial units near Manor Royal that need commercial-grade systems servicing throughout the year. Gatwick's proximity also means a lot of local firms are used to working around business premises, warehouses and even the odd hotel, not just houses. Whatever the job, someone fitting or servicing air con here needs to know how to route pipework neatly through a semi in Ifield versus a new-build flat near the town centre, and that local knowledge tends to show in how quickly a job gets done properly.
The businesses on this page come from public business listings, ranked by review rating and how many reviews they've built up, with a small boost given to those showing a working website and phone number. We then read each firm's homepage to check that air conditioning work, whether that's installation, servicing or repairs, is genuinely their main line of business. This step keeps general builders or electricians who only dabble in air con from cluttering up the results. Listings flagged as permanently closed get stripped out automatically, so you're not calling a number that rings dead. Where you spot a Trust Verified badge, that business has gone through our fuller check, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Full details of what that involves sit on our How We Verify page. Any business without that badge hasn't been independently verified by us, so it's worth doing your own homework before booking.
Before you commit to anyone, ask to see their F-Gas certificate, since it's a legal requirement for anyone handling refrigerant, and check whether they're registered with a recognised competent person scheme for the type of installation you need. Get a written quote that breaks down the unit cost, labour and any electrical work separately, and ask what warranty covers the compressor versus the installation itself. It's worth getting two or three quotes for anything beyond a simple service, because prices for a single split system installation in Crawley can vary by several hundred pounds depending on the make, the length of pipe run and whether scaffolding or a cherry picker is needed for outdoor unit placement.
How We Select & Rate The Best Air Conditioning Pros in Crawley
Rankings are based on review rating and review count pulled from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm air conditioning work is what they primarily do, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. See our How We Verify page for the complete list. Other businesses here haven't been independently verified by us and inclusion isn't an endorsement, so do your own checks before hiring.

How much does an air conditioning pro cost in Crawley?
A single split system supplied and fitted typically runs from around £900 to £1,800 depending on the unit's brand and output, while a multi-split covering two or three rooms can push past £3,000 once pipework and electrical work are factored in. A basic annual service usually costs between £70 and £120 per unit, more if it needs a regas. Prices shift depending on how far the outdoor unit sits from the indoor one, access (a loft conversion in Southgate will cost more than a ground-floor lounge in Langley Green), and whether you need a new electrical circuit run. Getting two or three quotes is normal practice and worth doing even for a straightforward job.
Do I need planning permission to fit air conditioning in Crawley?
Most domestic installations count as permitted development, so you won't need planning permission for a standard wall-mounted outdoor unit. That said, if you're in a conservation area, or your property is listed, or the unit would sit on a wall facing a road, it's worth a quick call to Crawley Borough Council's planning team to check first. Flats and leasehold properties often need freeholder or management company sign-off too, so check your lease before booking anyone.
How long does it take to install air conditioning in a typical Crawley home?
A single split system in a terraced or semi-detached house usually takes a day, sometimes less if the pipe run is short and there's easy access to an external wall. Multi-room systems with several indoor units can take two to three days, particularly in older properties around Ifield or Northgate where wall thicknesses and existing wiring can slow things down. Ask your installer for a realistic timeframe before work starts, including how long any making good (patching plaster, painting) will take afterwards.
What's the difference between an air conditioning service and a repair?
A service is routine maintenance, cleaning filters, checking refrigerant levels, inspecting the drainage and testing the system runs efficiently. It's generally recommended once a year, ideally before summer. A repair deals with a specific fault, a unit that's stopped cooling, an ice build-up on the coil, or an unusual noise from the compressor. If your system hasn't been serviced in a while, it's often the fault that gets picked up during a routine visit, so regular servicing can save you an emergency call-out fee later.
Can I get air conditioning installed in a flat in Crawley town centre?
Yes, though it depends on your lease and the building's management rules. Many flats near the town centre and around Southgate are leasehold, and freeholders sometimes restrict external alterations like wall-mounted condenser units. Check with your management company first, and if outdoor space is limited, ask an installer about ground or balcony-mounted units as an alternative to wall brackets.
How do I check an air conditioning firm in Crawley is legitimate before booking?
Ask to see their F-Gas certificate, since handling refrigerant without one is illegal, and check they're registered with a competent person scheme relevant to the installation type. Look them up on Companies House if they're a limited company to see how long they've been trading. Read through recent reviews rather than just the star rating, checking for comments about tidiness, timekeeping and how faults were handled after installation. Ask for proof of public liability insurance and get a written quote covering parts, labour and any warranty terms before you sign anything.
