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.
Our coverage in County Durham
We cover all of County Durham, including Darlington, Hartlepool, Stockton-on-Tees, Durham and Chester-le-Street. Wherever your premises are, the survey, quote and installation follow the same steps.
Postcode districts we cover include DH1, DH7, DL1, DL12, DL17, TS16, TS23 and TS29. For VRF and VRV air conditioning in County Durham, the survey looks at where the outdoor unit can go, how pipework will reach the indoor units and whether the electrical supply has capacity.
What the job covers
- 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
- Phased installation, pressure testing, commissioning and full F-gas records

From enquiry to handover in County Durham
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. We keep work areas in County Durham screened and tidy at the end of each day.
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.
What to think about in County Durham
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 County Durham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
Leased premises
If your County Durham premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Typical premises in County Durham
- 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.
Your questions answered
How much does a VRF system cost in County Durham?
Guide prices in County Durham run from about £2,295 to £4,650 per indoor unit (whole system), plus VAT. A typical job (office floor of 10–16 indoor units) costs £22,995–£74,500 plus VAT. We fix the price in writing after a free survey.
Do you also cover Tyne and Wear, Northumberland and North Yorkshire?
Yes. Alongside County Durham, we also cover Tyne and Wear, Northumberland and North Yorkshire. Each has its own page with local guide prices.
Can VRF connect to our BMS?
Yes, through the manufacturer's interface. We specify the right gateway at design stage.
When is VRF better than separate split systems?
Usually once you need more than about six to eight indoor units, want central control, or are short of space for outdoor units. One outdoor unit can replace many.
