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 Welwyn Garden City screened and tidy at the end of each day.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Before you book in Welwyn Garden City
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.
Access and parking
Town-centre jobs in Welwyn Garden City 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.
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Leased premises
If your Welwyn Garden City premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
