- Air conditioning running but not cooling
- A flashing light and a system that won’t run
Air conditioning repair in East Grinstead, done properly
Age alone does not decide whether a repair is worth it. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. We’re often asked to deal with a system that runs but doesn’t cool the room and a flashing light and a system that won’t run, across wall-mounted split systems, ducted systems and multi-split systems.
Whether it’s a shop or a house in East Grinstead, the system is an indoor unit, an outdoor unit and the pipework and wiring that join them. The fault can be at either end, or in between, so testing comes before any new parts.
We are 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.

Common problems we fix in East Grinstead
Leaks tend to start where pipes are joined: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Corrosion on coils can also cause leaks over time and many leaks are slow enough to go unnoticed for a while.
The things we’re asked about most are:
- A system that keeps cutting out
- New noises from the system
- An error code or flashing light on the unit
When cooling fails at a school like St Mary's CofE Primary School, we can time non-urgent repair work around lessons.

- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.

What the work involves, system by system
Wall-mounted split systems
Wall-mounted splits are the systems we repair most often. Drains, coils, fans, sensors and leaks account for many of the faults, and most are diagnosed on the first visit.
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 is not level can spill water too.
FAQs for East Grinstead
Is East Grinstead in your area for air conditioning repair?
We do: East Grinstead falls inside our working area. To start, give us a ring on 07833 053749, or email if that’s easier with a few photos.
Can I get a fixed-price quote for air conditioning repair in East Grinstead?
The easiest way is to phone 07833 053749 or email us with a few details and pictures. Where photos aren’t enough, a survey comes first and the fixed-price quote follows.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Why is not my air con cooling?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Check the filter and the settings first, and if that doesn’t fix it, phone us on 07833 053749 or fill in the contact form.
My air con is showing an error code. What should I do?
Codes differ by brand, and the same code can cover several faults. Tell us the code, the make and the model, and we will diagnose the fault on site.
When will I hear back?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.

What owners can safely do
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
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.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
