Air Conditioning Repair in Coryton
Our engineers work in Coryton on fault finding and repair for split, multi-split, ducted, cassette and VRF air conditioning, whatever the brand. A look at the job first, a fixed-price quote and written records at the end.
- A unit blowing warm air
- Ice forming on the indoor unit or pipes
- A flashing light and a system that won’t run
What owners can safely do
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
Never try to top up, release or handle refrigerant yourself. 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. If you suspect a leak, switch the system off and call us.
Air conditioning repair for homes and businesses in Coryton
Older systems raise a fair question: repair or replace?. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers VRF systems, ceiling cassettes and wall-mounted split systems, and people most often call us about a system that won’t switch on and a unit that barely blows any air.
A visit to Coryton is planned so we can usually finish in one go, though some parts have to be ordered from the manufacturer.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

FAQs for Coryton
Is Coryton within the area you cover?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Who do I call if my air conditioning fails in Coryton out of hours?
The emergency line is open around the clock, and Coryton is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Who has to arrange F-Gas leak checks?
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 install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Is it legal to repair an R410A system?
Yes. Any leak is repaired before recharging, and the work is recorded and we’ll give you an honest view on whether it’s worth it.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Coryton and across Thurrock. Let us know who the records should go to.
How the visit works
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. For businesses, we can usually work room by room or zone by zone. The work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Somewhere like Coryton, it helps to know about lanes, gates and where to park.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Finally, a check that it’s working and a record of what we did.
How to prepare
- Tell us about parking and loading
- Let us know where the consumer unit is
- Make sure we can reach the outdoor unit, or where it will go
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.

System by system
Condensate drains and pumps
Most water leaks from indoor units come back to the condensate system. Blockages, kinks and failed pumps are the usual causes, and a unit that has dropped out of level can leak.
Multi-split systems
With several pipe runs, finding a leak on a multi-split takes method. We test each run to find it, then repair, pressure test and recharge.
Looking after your system
Every system needs looking after, and most of it is easy. Our tips:
- Keep to the service interval the manufacturer recommends
- Switch the unit off if water is leaking from it
- Send us a photo of any code on the display
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, so we keep you posted.
Clean the filters regularly. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance, so keep them clean as the manual describes.
