How a job in County Down works
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung. We keep work areas in County Down screened and tidy at the end of each day.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.
What to think about in County Down
Planning and noise
Outdoor units on commercial buildings often need planning permission — particularly on a front elevation, in a conservation area or on a listed building — and councils may ask for a noise assessment.
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.
Power
Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.
Conservation areas
Historic streets and listed buildings in and around County Down 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 County Down
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
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.
Your questions answered
How much does commercial air conditioning installation cost in County Down?

Do you also cover County Antrim, County Armagh and County Tyrone?
Yes. Alongside County Down, we also cover County Antrim, County Armagh and County Tyrone. Each has its own page with local guide prices.
Do I need planning permission?
It depends on where the outdoor unit goes and the building. Units on a rear flat roof are often straightforward; front elevations, conservation areas and listed buildings usually need consent. We flag this at survey.
Will the system heat as well as cool?
Almost all modern commercial air conditioning is a heat pump that can heat as well as cool. Many businesses use it as their main heating in spring and autumn.
