Air conditioning for homes and businesses in Cheshunt
A single-room split system is typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, and commercial VRF systems are priced after a survey. When someone in Cheshunt asks us for air con, the first questions are normally price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Planning permission isn’t usually needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
Around Cheshunt, older homes and newer ones sit side by side, and that changes how the pipework goes in. Solid walls take longer to core drill than cavity walls, and a loft or a void can hide a pipe run that would otherwise be on show.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

What the work involves, system by system
Ducted systems
Ducted units can feed several rooms through a network of ducts, which suits new builds, extensions and refurbishments where ceilings are open.
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill, and keep it as short and neat as the building allows.
How it works
If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. In a town like Cheshunt, we fit the visit around you.
- 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.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Before we arrive
- Tell us about parking and loading
- Find the manual or the paperwork for the system, if you have it
- Mention any managing agent or landlord rules we need to follow
How to get a quote
Here’s what helps us quote: the address and the type of property, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then phone 07833 053749 or use the quote form.

Landlords, agents and facilities managers
We also work for facilities teams in offices, schools and public buildings across Hertfordshire. Larger buildings can be done in stages to keep disruption down.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
Air conditioning around Cheshunt
The 2021 Census found about 41% of households in terraced houses. With a terrace, the back wall or an extension roof is normally the best place for the outdoor unit.
Around St Mary the Virgin, a quick check of the listing and conservation maps is part of planning any install. Forty Hall, about 3 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

Why deal with it now?
Putting up with another summer of portable units and fans rarely makes sense. A fixed system removes the heat to the outside, runs more quietly in the room and can normally heat as well, so it works for you in winter as well. It’s easier to plan the job in Cheshunt before the warm weather arrives.
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. The price is fixed before work begins, and the quote sets out the VAT.

Cheshunt: your questions answered
Do I need planning permission for air conditioning in Cheshunt?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Cheshunt holds about 18 listed buildings and structures. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Broxbourne council, which is typically the planning authority for Cheshunt.
Can you do air conditioning in Cheshunt?
Yes. Cheshunt is one of the places we cover. Get in touch with the details and we reply the same working day.
How do you size the system?
It depends on the room, not only its floor area. Glazing, orientation, the roof and what goes on in the room all affect it and the survey covers each of them.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
Do you look at the job first?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
Do I need a new electrical circuit?
Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we’re NICEIC approved, so we can install and certify it.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
