How a job in Hayes works
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Hayes we confirm access and parking beforehand.
System design
Outdoor units, indoor units, branch boxes and pipe sizes are designed together, including the refrigerant charge and any leak detection.
Phased first fix
Pipework and controls cabling go in floor by floor, often out of hours in occupied buildings.
Pressure test and charge
The network is pressure tested, evacuated and charged with the calculated refrigerant quantity.
Commissioning
Each indoor unit is commissioned and the controls set up, with as-fitted drawings and F-gas records handed over.
Local points to consider
Leak checks
Larger VRF systems usually exceed 5 tonnes CO2 equivalent, so they need at least annual F-gas leak checks — more often at 50 tonnes and above.
Working hours
Most Hayes businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
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.
Typical premises in Hayes
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
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.
