The steps for a project in Hounslow
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. In Hounslow we agree timings around your opening hours.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
What to think about in Hounslow
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 Hounslow are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
