VRF (variable refrigerant flow) — called VRV by some manufacturers — is a commercial air conditioning system where one outdoor unit, or a bank of them, serves many indoor units through a shared refrigerant network.
Where we work around Witham
Witham has a compact centre of shops, cafés and offices, with business units on its outskirts. Chelmsford is about 14 km away.
That includes premises in CM8 and the surrounding districts. We also work in nearby Maldon, Braintree and Chelmsford. Buildings across Essex range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
What we do
- Heat load and diversity calculations for every zone
- Two-pipe (heat pump) or three-pipe / two-pipe heat recovery system design
- Refrigerant pipework sizing, branch selectors and refrigerant charge calculation
- Leak detection where the refrigerant concentration limits require it
- Central controls, scheduling and BMS integration

How it works in Witham
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Witham 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.
Things to check in Witham
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
Access and parking
Town-centre jobs in Witham 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.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
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.
Types of premises we cover in Witham
- 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.
