About our air conditioning repair in Donnington
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. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. The work covers VRF systems, ceiling cassettes and heat pumps, and common reasons people get in touch are a system that keeps cutting out and water leaking from the unit or through the ceiling.
Around Donnington, repairs tend to be home systems, garden rooms and a few businesses. Describe the fault and send a photo of the unit’s label so we can plan the visit.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Donnington questions
Will you come out to Donnington?
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.
Does sea air affect air conditioning in Donnington?
It can. Donnington is within about 3 miles of the coast, and salt air speeds up corrosion on outdoor units. Corrosion on the outdoor unit is one of the things we check when we diagnose a fault.
Do you look at the job first?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
How long does the visit take?
Your quote will say how long we expect to be there. In most cases, it takes anything from an hour or so to a full day, depending on the fault and the parts.
Can you repair an R22 air conditioning system?
Replacement is typically the better answer. R22 cannot be topped up with new gas, and parts for old models are scarce, so a new system on a modern refrigerant is typically the better investment.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.

Honest limits
Some problems need a different service or another trade:
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- Heat gains the system was never designed for
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is typically the answer)
Not sure which it is? You can call 07833 053749 or fill in the contact form and we’ll tell you honestly.

The process
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes anything from an hour or so to a full day, depending on the fault and the parts. Visits to Donnington are agreed with you in advance and planned so the job can be finished in one trip where possible.
- Diagnose: test the system until the cause is clear.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Finally, a check that it’s working and a record of what we did.
How to prepare
- Arrange for someone to be there to let us in
- Make sure we can reach the outdoor unit, or where it will go
- Tell us about any building rules, permits or sign-in
How to get a quote
Quotes don’t take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
Advice
Aftercare tips
After the visit, a few habits help:
- Keep the outdoor unit clear of leaves and clutter
- Don’t keep resetting a breaker that trips
- Never add refrigerant yourself or let anyone top up without finding the leak
The repair is written up: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records and it belongs with the system’s paperwork.
Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault, and early diagnosis usually means a smaller repair.
Signs you need air conditioning repair in Donnington
Water dripping from an indoor unit is normally about the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, while ice that forms on the coil and then melts can also cause drips.
Keep an eye out for these signs:
- A system that won’t switch on
- Water dripping from the indoor unit
- Ice forming on the indoor unit or pipes
Schools such as Chichester High School For Girls can report a fault on the 24/7 line and have non-urgent work done out of term.

The coast is only about 3 miles from Donnington. Coastal outdoor units can suffer from corroded coils and terminals, which can lead to poor cooling or trips.
