What the work involves, system by system
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling and access is part of the job. Many have condensate pumps, and pump failures are a common cause of ceiling leaks.
Wall-mounted split systems
Wall-mounted splits are the systems we repair most often. Typical faults include blocked drains, dirty coils and filters, failed fan motors, sensor faults and refrigerant leaks, and most are diagnosed on the first visit.
Air conditioning repair for homes and businesses in Aspley Guise
Age alone doesn’t 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. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers ceiling cassettes, VRF systems and ducted systems, and people most often call us about water leaking from the unit or through the ceiling and poor airflow even with clean filters.
A visit to Aspley Guise is planned so we can normally finish in one go, though some parts have to be ordered from the manufacturer.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What else we do in Aspley Guise
After we’ve gone
Looking after the system is mostly common sense. A few tips:
- Ask for the leak to be found, not just a top-up
- Check the settings and the remote’s batteries first
- Note any error code, or take a photo of the display
You get a note of the fault and what we did: the cause, the parts fitted and any refrigerant added or recovered. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Book an annual service. The engineer cleans what you cannot reach and picks up problems before they cause a breakdown and that’s normally simpler than a breakdown repair.
Questions from Aspley Guise
Will you come out to Aspley Guise?
Yes. Aspley Guise is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Aspley Guise for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Aspley Guise. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Will skipping a service affect the warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we’ll gladly show you ours.
Can you still repair R410A air conditioning?
Yes. Repairing and recharging existing R410A systems is still legal. As the GB phase-down continues, R410A is getting harder and dearer to buy and we talk through repair against replacement for older systems.
My air con is showing an error code. What should I do?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Note the code and switch the system off if it is not working, then phone 07833 053749 or email us.
