How it works in Stevenage
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Stevenage 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.
Points to plan for in Stevenage
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
Working hours
Most Stevenage businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Who we work with in Stevenage
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
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.
