From enquiry to handover in Cardiff
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly. We keep work areas in Cardiff screened and tidy at the end of each day.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Local points to consider
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
Access and parking
Town-centre jobs in Cardiff often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Premises we work in around Cardiff
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
Compliance in Wales: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
