How a job in Belfast 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. In Belfast we agree timings around your opening hours.
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 Belfast
Refrigerant in occupied rooms
Because one network carries a large refrigerant charge, small rooms on the system are checked against the safety limits in BS EN 378 and may need leak detection.
Working hours
Most Belfast businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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 Belfast 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.
Premises we work in around Belfast
- 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 Northern Ireland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under EU F-gas rules that apply in Northern Ireland, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Which postcodes do you cover in Belfast?
All of them, including BT1, BT2, BT3 and BT4. Give us your postcode when you enquire and we will confirm the visit details.
When is VRF better than separate split systems?
Usually once you need more than about six to eight indoor units, want central control, or are short of space for outdoor units. One outdoor unit can replace many.
What is heat recovery VRF?
A version that can cool some zones and heat others at the same time, moving heat around the building instead of dumping it outside.
