From enquiry to handover in Harpenden
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go. For sites in Harpenden we confirm access and parking beforehand.
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.
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.

Conservation areas

Landlord consent
Most commercial leases need the landlord's written consent before external units or wall penetrations go in. We can provide drawings and unit data sheets for the request.

Town-centre jobs in Harpenden 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.
