Our air conditioning service in WD18
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. We recommend a model on the survey and explain why it suits the room, and the manufacturer’s warranty terms are set out on your quote. The work covers multi-split systems, ceiling cassettes and ducted systems, and the jobs we see most are rooms under the roof that stay hot into the night and an old system that needs replacing.
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes a day or more, depending on the number of rooms, the pipe routes and the access, and we tidy up before we leave.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
What you’ll pay
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.

Air conditioning around WD18
From Watford, Rickmansworth and Cassiobury outwards, WD18 has every kind of home. Each install starts with a survey of the rooms, the walls and where the outdoor unit can go, then a fixed-price quote.
Refrigerant work is done by F-gas qualified engineers for a certified company, while NICEIC approval covers the electrical work, in WD18 as everywhere else.
Colney Butts: With historic houses such as High Elms Manor about 3.6 miles north, it’s a reminder that older homes nearby may be listed, which changes the planning rules. If you work from home near Watford High Street station, a home office that overheats is one of the easiest rooms to cool.
What owners can safely do
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
Leave it or put it right?
Fans and portables move warm air around rather than removing it. A properly installed split moves heat outside, keeps the noisy parts out of the room and in most cases heats too, so it earns its keep all year.

What air conditioning can’t fix
We’d rather tell you now than sell you work that will not help, so these are the things it will not cover:
- Stuffy rooms that need fresh air rather than cooling
- Damp from leaks or a lack of ventilation
- A building fabric problem such as single glazing or no loft insulation
Signs you need air conditioning
Some people come to us for heating rather than cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, so it gives out more heat than the electricity it uses. Most modern split systems work this way.
Reasons to give us a call include:
- A portable unit with a hose out of the window
- A study or office that overheats during the day
- A loft conversion that is too warm to use
- Rooms that get too hot to sleep or work in
WD18 questions
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
When will I hear back?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book, and we’re happy to show ours.
Can I do any of the installation 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 it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Who has to arrange F-Gas 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 can tell you which band your system falls into.
Is WD18 in your area?
Yes. Our engineers work in WD18, as part of our area across London and the South East. We are based in East Grinstead, West Sussex.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
