Air conditioning servicing in Castle Green, Surrey
Looking for air conditioning servicing in Castle Green? We diagnose first, fix the price and book the work around you, then sign it off with written records.
- Noisy fans or rattling from the outdoor unit
- Warning lights on the indoor unit
- An unpleasant odour when the system runs
What happens if it’s left?
A blocked condensate drain typically gets worse rather than better. What starts as a damp patch under the indoor unit can become water running down the wall, which is easily avoided by clearing the drain on a service. A dirty or faulty system works harder and costs more to run.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, ring us on 07833 053749 or fill in the contact form for straight advice and a fixed price.

How we handle air conditioning servicing in Castle Green
Servicing doesn’t mean topping up refrigerant. Refrigerant runs in a sealed circuit and shouldn’t need adding to. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. The work covers multi-split systems, ceiling cassettes and wall-mounted split systems, and common reasons people get in touch are humming, rattling or squealing from the system and frost or ice on the refrigerant pipes.
In a village like Castle Green, outdoor units often face hedges, fields or gardens, where seeds and leaves collect on the coil. A yearly service clears them.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What else we do in Castle Green
How it works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. A note on how to find the property and where to park makes a visit to Castle Green easier.
- We book a time that suits you and confirm the price.
- We switch the system on and check it in operation.
- Filters, coils, fans and drains are cleaned and cleared.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- It’s run once more to confirm all is well, and the record is left with you.
Preparing for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
- Dig out any previous service or F-Gas records

Castle Green: your questions answered
How often do you service systems in Castle Green?
For most homes, once a year. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.

We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
When is an F-gas leak check required?

What do you check on an air conditioning service?
A clean of the parts that collect dirt and a check of the parts that do the work. Filters, coils and drains are cleaned, and the electrics, controls and refrigerant circuit checked, and F-gas leak checks where they apply.

How we price air conditioning servicing
The survey or diagnosis tells us what the work involves. We look at:
- How far the pipework has to run, and where
- The brand, model and parts involved
- Whether it’s a one-off job or part of a maintenance contract
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will go through it with you.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The address and the type of property
- The outside wall, roof or yard where the outdoor unit sits or would go
- Your consumer unit or fuse board
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
What the work involves, system by system
Fans and electrics
We test the controls, the modes and the timers to make sure the system responds properly.
Indoor and outdoor coils
The outdoor coil does the same job on the other side of the system. It collects garden debris and dirt, so we clean it and clear the area around the unit.
A customer’s words
“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.”
