Air conditioning servicing in How Wood
A manufacturer’s warranty can come with conditions, and regular servicing may be one of them. The terms differ from brand to brand, so it’s worth reading yours and we’re happy to go through them with you. Our service record shows the work was done. The work covers ceiling cassettes, wall-mounted split systems and multi-split systems, and the jobs we see most are iced-up coils or pipework and systems that haven’t been serviced for a while.
For most homes near How Wood, a service once a year keeps the system efficient and the filters clean, and regular servicing can be a condition of some manufacturers’ warranties.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Questions from How Wood
Can you do air conditioning servicing in How Wood?
Yes. We work across London and the South East from our base in East Grinstead, and How Wood is part of that. Tell us a little about the job and we’ll take it from there.
Does my air con in How Wood need a yearly service?
A yearly visit is right for most households. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
How long does an air conditioning service take?
A service takes anything from an hour for a simple split system to most of a day for a larger installation. Any repair found on the day is priced and agreed before it’s done, so call 07833 053749 or email us to arrange a time.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
When is an F-gas leak check required?
The requirement starts at 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Owner checks or an engineer?
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 electrical side needs a competent person. If you need something moved, we can quote for it.
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 refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

- Frost or ice on the refrigerant pipes

- Warning lights on the indoor unit
Offices and shops near How Wood station can have their systems serviced without closing.
