How we handle air conditioning repair in Dedworth
Not sure whether it’s worth calling an engineer? Check the filter, the mode, the set temperature and the remote’s batteries first, and if that doesn’t fix it, phone us on 07833 053749 or send an email. We reply to enquiries the same working day. The work covers ducted systems, VRF systems and wall-mounted split systems, and common reasons people get in touch are a unit blowing warm air and ice forming on the indoor unit or pipes.
We prepare for a visit to Dedworth from the make and model you give us, and if a part has to be ordered, we tell you the price before we fit it.
Warranty periods vary by brand and by product. 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.

What we do, step by step
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. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Send pictures of the space and the outside wall, and we can plan the work near Dedworth.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair does not make sense, you will hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- The sign-off: the system tested in operation and the work recorded.
How to prepare
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the outdoor unit, or where it will go
- Let us know where the consumer unit is

Common questions in Dedworth
Will you come out to Dedworth?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Do you cover Dedworth for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Dedworth. Have the make, model and error code ready, and we’ll talk you through what happens next.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Can you still repair R410A air conditioning?
Yes. Repairing and recharging existing R410A systems is still legal. R410A is getting scarcer and dearer to buy as the GB phase-down tightens, so for older systems we compare the cost of a repair with a replacement.
My air con is showing an error code. What should I do?
Each manufacturer uses its own codes, and one code can have more than one cause. Tell us the code, the make and the model, and we’ll diagnose the fault on site.

Aftercare tips
Systems last better with the right care. Here’s what we suggest:
- Leave a tripping breaker off and call us
- Turn the system off if it’s dripping water
- Never add refrigerant yourself or let anyone top up without finding the leak
Keep the filters clean and the outdoor unit clear after the repair: clean filters every few weeks in heavy use and space around the outdoor unit. A yearly service catches problems before they become breakdowns.
Filter cleaning is the simplest prevention there is. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance and the manual shows how to clean them.
Before you call an engineer
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 escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
