Commercial Air Conditioning in Welshpool Designed, Installed and Kept Running Without Shutting Your Business Down

Wall-mounted split systems

One outdoor condenser serving one indoor unit. Simple, cost-effective and quick to install, which makes them the default for a single office, a treatment room, a small shop or a comms cupboard. Modern inverter splits modulate their output instead of cycling on and off, so they hold temperature more precisely and use noticeably less electricity than the fixed-speed units they replaced.

The limitation is aesthetics and coverage: a wall unit throws air from one point, so a long or partitioned space may need more than one, and the indoor unit is visible. Where that matters, a cassette or ducted option usually wins.

Multi-split systems

One outdoor unit serving several indoor units — the arrangement Lynda Dacruz describes in her review, where a five-way splitter supplied four rooms. Multi-splits save external space and reduce the number of condensers you have to find room for, which is often the deciding factor on a terraced high-street property or a building with restricted roof access.

They need careful pipe-run planning, because line lengths and level differences between indoor and outdoor units affect performance. That is survey work, not something to be decided on the day of installation.

Ceiling cassettes

Recessed into a suspended ceiling and blowing conditioned air out across two or four ways, cassettes are the standard for open-plan offices, retail floors and restaurants. Air distribution is far more even than a wall unit can manage across a wide space, and the only visible part is the grille.

They require ceiling void depth and a condensate route — most use an integral lift pump. Where the void is shallow or the ceiling is solid, a ducted or wall-mounted approach is the practical alternative.

Ducted systems

The indoor unit sits out of sight in a void or plant space and feeds grilles through ductwork. Nothing is visible in the room except the grilles, which is why ducted systems suit listed or design-sensitive interiors, hotel rooms and premium retail.

Ducted installation is the most involved of the options and needs to be planned alongside the building fabric. Done properly it is also the most discreet and can be zoned across several rooms from one unit.

VRV and VRF systems

Variable refrigerant volume/flow systems serve many indoor units from a modular outdoor plant set, varying refrigerant flow to each zone according to demand. On larger commercial buildings this is the efficient choice: unoccupied zones draw almost nothing while busy zones get full output, and heat-recovery versions move heat from a zone that needs cooling into a zone that needs heating.

VRV/VRF also scales. If you are fitting out a floor now and another floor next year, the plant and riser can be planned for it, which is far cheaper than retro-fitting a second independent system later.

Heating as well as cooling

Nearly everything we install is a heat pump: reverse the cycle and the same equipment heats the space, typically delivering several units of heat per unit of electricity consumed. For businesses in mid-Wales and Shropshire with poor or expensive existing heating, that shoulder-season and winter heating is often what justifies the installation rather than summer cooling alone.

Commercial versus domestic work

The physical hardware overlaps, but commercial work adds heat-load complexity from people and equipment, longer pipe runs, three-phase supplies on larger plant, access and phasing constraints, RAMS and site induction requirements, and F-Gas record keeping for the operator. Domestic work is usually a single visit or two with a focus on quiet running and a tidy finish.

We do both, with the same engineers. If you want the domestic side, see our domestic air conditioning page — installations may currently qualify for 0% VAT, rising to 5% from April 2027.
