How it works in Stevenage
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly. In Stevenage we agree timings around your opening hours.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Things to check in Stevenage
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Access and parking
Town-centre jobs in Stevenage 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.
Refrigerant rules
Since 1 January 2025, new single split systems holding under 3 kg of refrigerant in Great Britain cannot use refrigerant with a GWP of 750 or more — in practice, R32 or lower.
Working hours
Most Stevenage businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Which postcodes do you cover in Stevenage?
All of them, including SG1. Give us your postcode when you enquire and we will confirm the visit details.
Single split or multi-split?
Separate singles are more resilient and can be cheaper for two rooms; a multi-split saves outdoor space. We price both where it is close.
Does a small split need F-gas leak checks?
It depends on the refrigerant charge and type. Many small R32 splits fall below the 5 tonnes CO2 equivalent threshold for mandatory leak checks, but they still need installing and servicing by F-gas certified engineers.
