How a job in Chalfont St Peter 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 Chalfont St Peter 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 Chalfont St Peter
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 Chalfont St Peter are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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 Chalfont St Peter 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 Chalfont St Peter
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.

Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
