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.

How it works in Carlisle
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 Carlisle 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.
Things to check in Carlisle
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.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
Leased premises
If your Carlisle 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.
Types of premises we cover in Carlisle
- 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.
Questions about VRF / VRV in Carlisle
How much does a VRF system cost in Carlisle?
Guide prices in Carlisle run from about £2,395 to £4,850 per indoor unit (whole system), plus VAT. A typical job (office floor of 10–16 indoor units) costs £23,995–£77,995 plus VAT. We fix the price in writing after a free survey.
Which postcodes do you cover in Carlisle?
All of them, including CA1 and CA99. Give us your postcode when you enquire and we will confirm the visit details.
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.
Does a VRF system need F-gas leak checks?
Usually yes. Most VRF systems hold enough refrigerant to exceed 5 tonnes CO2 equivalent, which triggers at least annual leak checks and record keeping.
