How it works in Larne
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 Larne 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.
Points to plan for in Larne
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
Leased premises
If your Larne 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.
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
Conservation areas
Historic streets and listed buildings in and around Larne are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
Typical premises in Larne
- 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.
Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
