About our air conditioning repair in Farnham
Age alone does not decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers multi-split systems, VRF systems and ceiling cassettes, and common reasons people get in touch are water leaking from the unit or through the ceiling and new noises from the system.
Shops, offices and homes in Farnham all use the same basic kit: an indoor unit, an outdoor unit and the pipes between them. The fault can be at either end, or in between, so testing comes before any new parts.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

What the work involves, system by system
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. Sensor faults can stop the system or confuse it and boards can fail with age or after electrical problems.
Wall-mounted split systems
The indoor and outdoor units of a split communicate through a cable. A break in that communication typically brings up an error code and testing finds whether it’s the cable, a board or a connection.

What air conditioning won’t do
We’d rather tell you now than sell you work that will not help, so these are the things it won’t cover:
- A unit whose parts are no longer made (replacement may be the only option)
- A building problem rather than a system fault
- A unit that was never big enough for the room
Not sure which it is? You can call us on 07833 053749 or drop us a line and we will tell you honestly before you book.
What the work covers
- VRF systems
- Ducted systems
- Heat pumps

The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. The work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Photos of an existing unit and its label help with repairs and servicing in Farnham.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Next, a plain explanation and a fixed price.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Finally, a check that it’s working and a record of what we did.
Before we arrive
- Make sure we can reach the outdoor unit, or where it will go
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Let us know if the building has a permit or sign-in process

Why is my air conditioning icing up?
Ice is a symptom of low airflow or low refrigerant. A clogged filter, a fan problem or a leak are typical. Switch the system off, let it thaw and ring us on 07833 053749 or fill in the contact form.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
