Our air conditioning service in CO4
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. The work covers multi-split systems, wall-mounted split systems and ducted systems, and the jobs we see most are not knowing which system, size or brand to choose and rooms heated by plug-in heaters.
You don’t need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
What you will pay
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you will get one fixed price.
What you get with us
- One contact for properties across the South East and London
- Checkatrade member
- We reply to enquiries the same working day
- Every job looked at before it’s priced

Colchester: Close to Colchester Town station? A small study or box room used for work can usually be cooled with a single indoor unit. Living close to Church of St Peter? Some older properties in parts like that are protected, and the survey finds out whether yours is.
What the work involves, system by system
Offices, shops and commercial rooms
Commercial rooms often need more than one unit and controls that suit how the space is used. We size for the people, equipment and glazing in the space, and plan the work so the business keeps running.
Outdoor unit positions
Outdoor units are fitted on wall brackets, at ground level or on a flat roof, depending on the property and the pipe route. It needs space around it to breathe and for an engineer to work on it.
Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
What happens if it’s left?
The best time to plan air conditioning is before the hot weather, not during it. When people buy in a hurry, the unit is often the wrong size or badly placed, which is costly to undo. A survey now gives time to choose properly.
Questions to ask before booking
- Proof of F-Gas company certification
- How extra work would be agreed if they find something unexpected
- How VAT is shown, and which rate applies
- If the figure could change on the day
Why it fails
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window cannot close properly and the noisy part of the unit is in the room. With a split system, the compressor lives outside.
The things we are asked about most are:
- A system on old refrigerant that is due for replacement
- Fans and portables that do not keep up
- Uncertainty over the right type and size of system
- Working from home in a room that gets too warm
Questions from CO4
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Where will you put the outdoor unit?
We agree it with you on the survey. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We will tell you what to check before we fit it.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Is CO4 in your area?
Yes. CO4 is part of the area we cover, 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: a look first, a fixed-price quote and written records.
