From enquiry to handover in Hemel Hempstead
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids.
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. In Hemel Hempstead we agree timings around your opening hours.
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 Hemel Hempstead
Refrigerant in occupied rooms
Because one network carries a large refrigerant charge, small rooms on the system are checked against the safety limits in BS EN 378 and may need leak detection.
Working hours
Most Hemel Hempstead businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
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.
Who we work with in Hemel Hempstead
- 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.
