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.
Working in Bexley
Premises in Bexley are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.
That includes premises in DA15 and the surrounding districts. We also work in nearby Welling, Dartford and Swanley. We plan installations in Bexley so the noisy work — core drilling, ceiling access, lifting plant — happens when it disturbs your business least.
What is included
- Heat load and diversity calculations for every zone
- Refrigerant pipework sizing, branch selectors and refrigerant charge calculation
- Leak detection where the refrigerant concentration limits require it
- Central controls, scheduling and BMS integration
- Phased installation, pressure testing, commissioning and full F-gas records

How it works in Bexley
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 Bexley 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.
Things to check in Bexley
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 Bexley 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.
Conservation areas
Historic streets and listed buildings in and around Bexley are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Who we work with in Bexley
- 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.
