When air con fails in Crawley
VOA council tax data date about 56% of homes in and around Crawley to the post-war years, 1945 to 1972, and about 36% of households live in terraced houses, according to Census 2021 figures. On terraced streets, outdoor units are typically at the back, so tell us how we get to the rear of the property. Roughly a third of a mile or less from central Crawley, you reach the Brighton Road Conservation Area. 8 conservation areas lie within a mile of central Crawley. Parish Church of St John the Baptist, listed at grade II*, is one of roughly 19 protected buildings and structures in the half-mile around Crawley’s centre. Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed.
For a school like Three Bridges Junior School, urgent repairs can be booked straight away and bigger work in the holidays. Shops and offices around Crawley station often cannot wait for cooling to come back, which is what the 24/7 line is for.

When it’s something else
We’d rather tell you now than sell you work that will not help, so these are the things it will not cover:
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is usually the answer)
- No power to the building at all
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
If you’re not sure, just call 07833 053749 and we’ll give you a straight answer before you book.

Common questions in Crawley
Is Crawley in your area for air conditioning repair?
Yes. Crawley is one of the places we cover. Tell us a little about the job and we will take it from there.
Can I get a fixed-price quote for air conditioning repair in Crawley?
Send us pictures of the room or the system and a few details about the property. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Can you come out for an emergency air conditioning repair?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Call 07833 053749 and tell us the make, the symptoms and any error code, and we will agree the next steps with you.
Do I need to service the system to keep the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
What you can do yourself, and what needs us
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 refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
How the job changes from property to property
Condensate drains and pumps
The condensate drain is behind most indoor unit leaks. Drains block with dirt and growth, pipes get kinked and pumps fail, and a unit that has dropped out of level can leak.
Fans and compressors
Fan motors and bearings wear over time, and the first sign is often noise or weak airflow. Indoor and outdoor fan motors can usually be replaced where the parts are available.
How the visit works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Work at a business in Crawley can be split over a few visits so you keep trading.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Preparing for the visit
- Keep pets and children away from the work area
- Mention any roof access, ladders or high-level work
- Arrange for someone to be there to let us in
