How it works in Southampton
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 Southampton 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 Southampton
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Southampton are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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.
Working hours
Most Southampton businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Premises we work in around Southampton
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.

- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
