How we work in Carshalton
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 Carshalton 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.
What to think about in Carshalton
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 Carshalton 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.
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 Carshalton 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 Carshalton
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.

Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

How long does a VRF system last?

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.
