How it works in Watford
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. In Watford we agree timings around your opening hours.
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.
What to think about in Watford
Planning and noise
Outdoor units on commercial buildings often need planning permission — particularly on a front elevation, in a conservation area or on a listed building — and councils may ask for a noise assessment.
Working hours
Most Watford businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
Access and parking
Town-centre jobs in Watford 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.
Types of premises we cover in Watford
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
