We work across St Albans's postcode districts, including AL1 and AL3. Nearby, we also cover Harpenden (about 8 km), Hatfield (about 8 km) and Hemel Hempstead (about 8 km). 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 it works in St Albans
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 St Albans 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 St Albans
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.
Conservation areas
Historic streets and listed buildings in and around St Albans are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
Leased premises
If your St Albans 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.
Typical premises in St Albans
- 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.
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.
