Air conditioning repair in Crawley Down, done properly
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, which is why diagnosis comes first. The work covers ducted systems, wall-mounted split systems and multi-split systems, and the jobs we see most are water leaking from the unit or through the ceiling and a unit blowing warm air.
Outdoor units around Crawley Down often sit near hedges, trees and lawns, where leaves and cuttings can clog the coil and cut the cooling. We check the coil early on.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

After we’ve gone
How well a system lasts depends on use and care. We suggest:
- Send us a photo of any code on the display
- Book an annual service after the repair
- Clear debris away from the outdoor fan
If parts are needed, we tell you what’s on order and book the return visit with you. Parts lead times depend on the supplier and we’ll keep you updated.
Keep the outdoor unit clear. Leaves, plants and stored items around it restrict airflow and make the system work harder, and debris can get into the fan.
What we do, step by step
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes anything from an hour or so to a full day, depending on the fault and the parts. Send pictures of the space and the outside wall, and we can plan the work near Crawley Down.
- Describe the problem and the brand, and mention any code on the display.
- A diagnosis visit finds the cause with proper tests.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.
- The system is run and checked, and you get a written note of the repair.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Move furniture away from the wall where we will be working
- Unlock any gate, garage or side passage we need

When something else is needed
Not every problem is solved by air conditioning repair, and we’d rather say so up front. It will not put right:
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- Heat gains the system was never designed for
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is typically the answer)
If in doubt, call us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll say what we think.

Questions from Crawley Down
Who do I call if my air conditioning fails in Crawley Down out of hours?
Crawley Down is within our area, and the emergency line is open 24/7. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Do you cover smaller places like Crawley Down?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Which brands do you work with?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Why is not my air con cooling?
It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which, then give you a fixed price to fix it.
How long will you be on site?
Your quote will say how long we expect to be there. As a guide, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive.
What a repair looks like in Crawley Down
Listed buildings are part of the picture here: about 4 within half a mile of the centre, such as Burleigh Cottage (grade II). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. The last census (2021) found about 78% of households in detached or semi-detached houses. Tell us where your outdoor unit is and how to reach it, so we can plan the visit.
Many breakdowns start small, with a drip, a smell or a unit that takes longer to cool. A photo of the error code and the unit’s rating label helps us plan the repair.
