Air conditioning repair for homes and businesses in Knowl Hill
Not sure whether it’s worth calling an engineer? A quick check of the filter, settings and remote can rule out the simple causes, then ring 07833 053749 or drop us a line if the problem is still there. We reply to enquiries the same working day. The work covers VRF systems, ceiling cassettes and heat pumps, and the jobs we see most are a suspected refrigerant leak and a system that keeps cutting out.
We plan the trip to Knowl Hill so the repair can be finished in one visit where possible, though some parts have to be ordered from the manufacturer.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

Looking after it afterwards
A little care keeps the system in better shape. Our advice:
- Keep the outdoor unit clear of leaves and clutter
- Check the settings and the remote’s batteries first
- Send us a photo of any code on the display
You get a note of the fault and what we did: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Use the system sensibly. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs, so it is not running flat out all day.
Owner checks or an engineer?
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.

Knowl Hill questions
Do you cover Knowl Hill for air conditioning repair?
Yes. Knowl Hill is one of the places we cover. To start, phone us on 07833 053749 or send an email with a few pictures.
Is there an emergency air con repair line for Knowl Hill?
Knowl Hill is within our area, and the emergency line is open 24/7. Say what the system is doing and whether it shows a code, and we will advise on the next step.
What can I do with an old R22 system?
R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak typically means replacement. We will set out the options and quote for a replacement where it makes sense.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Seeing the property in photos first means the trip to Knowl Hill can be planned properly.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Next, a plain explanation and a fixed price.
- Where a repair does not make sense, you will hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Sign off: prove it works and record the visit.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Dig out any previous service or F-Gas records
- Tell us about parking and loading
How to get a quote
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. After a look at the job, by photos or a survey, the price is fixed. To get going, ring us on 07833 053749 or send an email.

Leave it or put it right?
A struggling system costs more to run. A dirty coil, a blocked filter or a low refrigerant charge all make the system work harder for less cooling, and the extra strain can shorten the life of the compressor. Dealing with it now is usually simpler than a breakdown later.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
