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.
Before you book in Belfast
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.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
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.

Do you also cover Castlereagh, Newtownabbey and Lisburn?
Yes. Alongside Belfast, we also cover Castlereagh, Newtownabbey and Lisburn. Each has its own page with local guide prices.
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.
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.
Can a split system heat in winter?
Yes. Modern split systems are heat pumps and can heat efficiently down to well below freezing.
