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.

Principal bedroom with cove-lit ceiling and flush linear diffusers

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
External condenser unit and line covers installed on a brick elevation

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

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.

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.
