- A musty or damp smell when the unit starts
- Error codes or flashing lights on the indoor unit
- Systems that need a 6 or 12-monthly leak check
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. On the day, both are in the same hands. On site, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Work in Charndon is booked in advance at a time that suits you.
- First, we agree a time and confirm the cost of the service.
- We switch the system on and check it in operation.
- We clean the filters, coils and fans and clear the condensate drain.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- We run the system again and leave you a service record.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Move furniture away from the wall where we will be working
- Let us know if the units are on a roof, a high wall or in a locked area

What the work involves, system by system
Filters
Certain indoor units carry additional filters alongside the main ones. We check these as well and explain what the manufacturer recommends.
Wall-mounted, ducted and cassette units
Ducted units sit out of sight in ceiling voids. We need access to the unit, its filters and its drain so it helps to know where the access is before we arrive.

Your questions about air conditioning servicing in Charndon
Does my air con in Charndon need a yearly service?
A yearly visit is right for most households. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you cover Charndon for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Charndon is part of that. Just call 07833 053749 with a few details.
Do you do service contracts for air con?
Yes, with visits planned to suit how hard the system works. The price is fixed with your quote and you get a record after every visit.
When is an F-gas leak check required?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for example, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
What does an air con service involve?
Filters, coils, fans and the condensate drain are all cleaned and checked. We also check the electrical connections, the controls and the refrigerant performance, with an F-gas leak check where the system requires one.
Who is responsible for leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Will servicing keep my manufacturer’s warranty valid?
That is down to your manufacturer’s terms, which vary. Where servicing is a condition, keeping an annual service record helps show the terms were followed, and we can explain what your brand asks for.
After we’ve gone
So the system stays in good health:
- Make sure the condensate outlet can drain
- Report drips, smells or noises early
- Diary the next service before this one is forgotten
The best time to book the next service is now, while you remember. Spring suits systems used mainly for cooling, and autumn suits those used for heating, though any time of year works.
Check that the condensate pipe outside can still drain. If the outlet is blocked, the water has to go somewhere, and that’s usually back towards the indoor unit.
Common problems we fix in Charndon
Each indoor unit makes water when it cools, and that water needs a clear route out. Sludge and debris can block the tray, the pipe or the pump and the result is drips from the indoor unit.
These are the situations we see most often:
- Drips or damp patches below an indoor unit
- An unpleasant odour when the system runs
- Frost or ice on the refrigerant pipes
If you cannot remember the last service, it’s probably due.
Questions to ask before booking
- What’s in the price and what is not
- What records you get at the end
- Whether anyone has checked the property or the system first
