How it works in St Austell
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung. We keep work areas in St Austell screened and tidy at the end of each day.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.

Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.

Which refrigerant will you use?
In Great Britain, new single split systems holding less than 3 kg of refrigerant cannot use a refrigerant with a global warming potential of 750 or more, so most are now R32. Larger systems may use R32, R454B or R410A depending on the equipment. We state the refrigerant and charge in the quote.
Do I need planning permission?
It depends on where the outdoor unit goes and the building. Units on a rear flat roof are often straightforward; front elevations, conservation areas and listed buildings usually need consent. We flag this at survey.
