How it works in Brentwood
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 Brentwood 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 Brentwood
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 Brentwood businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
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.
Types of premises we cover in Brentwood
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
