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 Hatfield
In Hatfield, typical premises are high-street shops, offices above them, surgeries, salons and local industrial units. Watford is about 17 km away.

Buildings across Hertfordshire range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

How we work in Hatfield
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Hatfield 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.
Points to plan for in Hatfield
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 Hatfield businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
Conservation areas
Historic streets and listed buildings in and around Hatfield are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Hatfield
- 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 Hatfield
How much does a VRF system cost in Hatfield?
Guide prices in Hatfield run from about £2,650 to £5,350 per indoor unit (whole system), plus VAT. A typical job (office floor of 10–16 indoor units) costs £26,500–£85,995 plus VAT. We fix the price in writing after a free survey.
Do you also cover Welwyn Garden City, St Albans and Potters Bar?
Yes. Alongside Hatfield, we also cover Welwyn Garden City, St Albans and Potters Bar. Each has its own page with local guide prices.
Which postcodes do you cover in Hatfield?
All of them, including AL10, DN7 and HR6. 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.
What is the difference between VRF and VRV?
None in practice. VRV is one manufacturer's trademark; VRF is the generic name for the same type of system.
