How it works in Dereham
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 Dereham 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
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Access and parking
Town-centre jobs in Dereham 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.
Conservation areas
Historic streets and listed buildings in and around Dereham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
