Choosing the system type

Single room, straightforward wall available, budget-led: a wall-mounted split. Several rooms and limited outdoor space: a multi-split from one condenser. Suspended ceiling and an open-plan floor: a four-way cassette for even distribution. Nothing may be visible: ducted, fed through grilles. A whole building with varying zone demand: VRV/VRF with modular outdoor plant.

The choice is driven by the fabric of the building and how the space is used, not by preference. We will tell you when the cheaper option is genuinely fine — and when it will disappoint you.

Pipework, refrigerant and insulation

Refrigerant pipework is copper, brazed or flared to manufacturer specification, insulated along its whole length including behind trunking. Uninsulated or poorly insulated pipe sweats, wastes capacity and eventually drips onto whatever is beneath it. Line length and vertical separation between indoor and outdoor units matter: exceed the manufacturer's limits and capacity drops and oil return suffers.

Modern systems typically use R32 or R410A refrigerant. R32 has a substantially lower global warming potential and better efficiency, which is why most new equipment we install uses it. All refrigerant handling is F-Gas certified work and recorded.

Condensate management

Cooling produces water — a surprising amount of it. It has to go somewhere with a reliable fall to a drain, or be lifted by a condensate pump to somewhere it can. This is planned before the indoor unit position is fixed, because the alternative is a pump retro-fitted into a bad position or a drain that backs up in three summers' time.

Outdoor unit siting

The condenser needs clear airflow, service access, secure mounting on brackets or feet, and enough distance from windows and boundaries to keep noise reasonable. Enclosed corners and tight recesses cause recirculation of hot exhaust air, which cripples efficiency on exactly the days you need it most. On commercial buildings we also consider roof loading, access for future servicing and whether the position is defensible from a planning or neighbour perspective.

Electrical supply and controls

Most domestic and small commercial systems run from a dedicated single-phase circuit; larger plant may need three-phase. Controls range from a simple wall controller through to central controllers, timers, occupancy scheduling and app control. Getting scheduling right on a commercial system is one of the cheapest efficiency wins available — cooling an empty building overnight is pure waste.

Commercial versus domestic installation

Domestic installations are typically one or two days, single-phase, with priority on quiet operation, discreet pipe runs and a clean finish. Commercial installations add heat load from people and equipment, phasing around trading, RAMS and induction requirements, potential three-phase supplies, and refrigerant record keeping for the operator.

Domestic installations may currently qualify for 0% VAT, rising to 5% from April 2027 — ask us about eligibility when we quote.

Replacing an existing system

Replacements are not automatically a like-for-like swap. Existing pipework can sometimes be reused if it is the right size, in good condition and compatible with the new refrigerant — and sometimes it absolutely cannot, in which case reusing it is a false economy that contaminates a new system. We check rather than assume, and tell you which it is.
