Air conditioning across CM3: what to expect
Not sure what you need, or where it would go? Just ring 07833 053749 or send an email with pictures of the rooms and the outside of the property, and you will hear back from us the same working day about a survey or a fixed-price quote. We’re often asked to deal with a loft conversion that’s too warm to use and an old system that needs replacing, on multi-split systems, ducted systems and VRF systems.
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes anything from a day for one room to several days for a multi-room or ducted system.
- We survey the property, or work from your photos for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How we quote
Every job is different, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.
What you get with us
- Emergency calls taken 24/7
- We diagnose before we treat
- Members of Checkatrade
- MCS certified heat pump installers

Air conditioning around CM3
From Chelmsford, Maldon and South Woodham Ferrers outwards, CM3 has every kind of home. Each install starts with a survey of the rooms, the walls and where the outdoor unit can go.
London and the South East cover everything from city flats to rural cottages. We are F-Gas certified, NICEIC approved and MCS certified for heat pumps. In the coastal parts of CM3, outdoor units benefit from a sheltered position and regular servicing.
South Woodham Ferrers: If your home is in one of the older streets near Holy Trinity, it’s worth checking whether it’s listed or in a conservation area before an install. Plenty of people near South Woodham Ferrers station split the week between the train and a spare room, and that spare room is often the first to get a unit.
Why act early?
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. Older R410A systems have a GWP of 2088.
Questions to ask before booking
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- If the figure could change on the day
- Whether the manufacturer’s warranty depends on regular servicing
- Which brand and model they’re proposing, and why
Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do 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. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Pricing air conditioning in CM3
Every job gets its own quote. This is what makes a difference:
- What state the existing equipment is in
- Whether it’s a one-off job or part of a maintenance contract
- Access, including height, roofs and ladders
- Which make and model is being fitted or worked on
Height, access and the distance between the indoor and outdoor units can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
There’s no need for technical detail. Just send:
- A few photos of the room and the wall the unit is on, or will go on
- The address and the type of property
- Your consumer unit or fuse board
- Your installation or service records
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.
Keeping the system healthy
Looking after the system is mostly common sense. Our tips:
- File the paperwork with the manual
- Report drips, noises or error codes right away
- Keep the outdoor unit clear of leaves, plants and clutter
- Shut doors and windows when it’s on
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Pipework outside is covered in trunking or insulated and neatly fixed, so the job looks as tidy as it works.
Regular filter cleaning is the simplest thing you can do. Blocked filters cut airflow and make the system work harder, which costs you more to run.
CM3: your questions answered
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and AirCon Doctor is certified.
What size air conditioning unit do I need?
It depends on the room, not only its floor area. Windows, the direction the room faces, the roof above and the people and equipment in it all count and the survey covers each of them.
Is planning permission needed for the outdoor unit?
That depends on what’s being fitted and where. Heat pumps on houses in England can be permitted development when they meet set conditions, including the MCS 020(a) noise check, while a unit that only cools isn’t covered and needs checking with the council. Flats, listed buildings and conservation areas have tighter rules. This is general information, not legal advice.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How long does it take to fit air conditioning?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
