The price is fixed up front and the records are handed over at the end. People searching for “air con near me” in Great Waltham want two things: a sensible price and someone qualified. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.

How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. Pictures of the space and where the outdoor unit could go let us plan the work in Great Waltham.
- 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.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- 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.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the building has a permit or sign-in process

What affects the quote in Great Waltham
Your quote is based on your property. We consider:
- The equipment or parts the job needs
- The pipe route between the units
- Whether it’s a one-off job or part of a maintenance contract
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Helping us quote
Photos and a few facts are often enough to price a simple job. Useful things to send:
- The paperwork from the last service, if you have it
- The address and the type of property
- A close-up of the unit’s label showing the model number
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Great Waltham: your questions answered
Will you come out to Great Waltham?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Will air conditioning in Great Waltham need planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Great Waltham sits inside the Great Waltham Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Chelmsford council, typically the authority for Great Waltham.
Do you offer emergency call-outs?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
Can you fit air conditioning in a leasehold flat?
In many cases, but permissions come first. You’ll usually need the landlord’s or management company’s consent for the outdoor unit and the pipe route and the lease will say. Permitted development rules for flats are also tighter than for houses, so we point out anything that may need permission on the survey. This is general information, not legal advice.
Signs you need air conditioning in Great Waltham
In shops, offices and restaurants, the heat comes from customers, staff, equipment and lighting as well as the sun. Keeping staff and customers comfortable is normally what prompts the call, and some rooms need cooling for the equipment as much as the people.
What we’re most often called about:
- Portable units that are noisy and barely cope
- Working from home in a room that gets too warm
- A loft room or top floor that bakes in summer
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed.
Questions to ask before you book
- What the manufacturer’s warranty covers and for how long
- Whether they looked at the job before pricing it
- Whether the price is fixed or an estimate
When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Problems with a gas boiler or the radiators
- Building damp that has a structural cause
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
Not sure which it is? You can ring us on 07833 053749, or email if that’s easier and we will tell you honestly before booking.
What the work covers
- Ceiling cassettes
- Ducted systems
- Air-to-air heat pumps

Homes in Great Waltham and air conditioning
The Valuation Office Agency’s council tax figures show about 49% of homes in the Great Waltham area were built in 2000 or later, and about 72% of households live in detached or semi-detached houses, according to the last census (2021). Newer homes typically have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. Houses normally have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Around Church of SS Mary and Laurence, a quick check of the listing and conservation maps is part of planning any install.
