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.
Caernarfon and surrounding areas
In a town like Caernarfon, a single wall unit for a shop or a cassette for a surgery makes a real difference in summer.
That includes premises in LL55 and the surrounding districts. We also cover Bangor, Gwynedd, Holyhead and Llandudno, all within easy reach of Caernarfon. In Caernarfon, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.

How a job in Caernarfon works
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 Caernarfon 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 Caernarfon
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.
Access and parking
Town-centre jobs in Caernarfon 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.
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
Leased premises
If your Caernarfon 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.
Premises we work in around Caernarfon
- 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.
Two rules matter for most businesses in Wales: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

All of them, including LL55. Give us your postcode when you enquire and we will confirm the visit details.
When is VRF better than separate split systems?
