Air conditioning
Cooling and heating,
properly sized
Wall-mounted splits through to full VRF. Installed so the equipment disappears into the building and keeps working long after handover.
01
Ducted & concealed
The indoor unit sits above the ceiling and the only thing in the room is a slot diffuser — or nothing at all, where supply and return are set into a bulkhead or cove.
It is the option that suits high-specification interiors, and the one that has to be planned earliest: duct routes, access panels and condensate falls all need to be agreed before the ceilings are boarded.
Typically installed as
- Ducted units above ceiling voids and bulkheads
- Linear slot and continuous slot diffusers
- Ceiling cassettes in flat soffits
- Concealed returns through joinery and cornice
02
Splits & multi-splits
A single wall unit for a hot bedroom or a home office, or one outdoor unit serving several rooms. The retrofit option for houses that are already finished.
Most of the work is in the routing: getting pipework and condensate from the indoor unit to the outdoor unit without cutting through anything that matters, and in trunking that follows the lines of the elevation rather than crossing them.
Typically installed as
- Single split — one indoor, one outdoor
- Multi-split — up to several indoors on one outdoor
- High-wall, low-wall and floor-standing units
- VRF for whole buildings and commercial floors

Section through
a ceiling void
What a concealed installation actually looks like above the ceiling — and why the routes have to be agreed before anything is boarded.
04
Siting the
outdoor unit
Where the condenser sits decides how well it runs, how easily it can be serviced, and whether it passes an acoustic assessment at the neighbour's window.
05
How a job runs
01
Survey
A site visit to measure the rooms, check the fabric and the glazing, and find workable routes for pipework, condensate and power before anything is priced.
02
Design & quote
Equipment sized to the actual heat load, not the room count. A written quote listing the units, the indoor and outdoor positions and what is included.
03
Install
First fix alongside the other trades, then second fix once ceilings and joinery are closed up. Cores drilled, brackets set, condensate falls checked as we go.
04
Commission & certify
Systems pressure-tested, evacuated, charged and run on heating and cooling. Refrigerant logged and paperwork handed over.
05
Service
Planned maintenance to keep filters clean, drains clear and manufacturer warranties valid — with F-Gas leak checks where the charge size requires them.
06
Common questions
Do I need planning permission for air conditioning?
For most houses the outdoor unit falls under permitted development, provided it sits within size limits, is not on a wall facing a highway and the property is not listed or in a conservation area. Flats, listed buildings and conservation areas usually do need consent. We will tell you which applies at survey.
Will it heat as well as cool?
Yes. Every system we install is a heat pump — it reverses to provide heating in winter, typically at a lower running cost than electric heating and often lower than gas, depending on your tariff.
How disruptive is the installation?
A single split in an existing house is usually one to two days. A fully ducted system in a new build or refurbishment is phased with the other trades: first fix before the ceilings close, second fix once plastering and joinery are complete.
How often does it need servicing?
Annually for domestic systems, and more frequently for commercial equipment or anywhere with heavy dust or grease. Servicing keeps manufacturer warranties valid; systems above certain refrigerant charges also require F-Gas leak checks by law.
