How it works in Boston
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route. For sites in Boston we confirm access and parking beforehand.
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.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Local points to consider
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.
Leased premises
If your Boston 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.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Who we work with in Boston
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
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.
