New build and renovation air conditioning across County Down
Renovations in Bangor are the easiest jobs to make invisible, because the pipework goes in before the plaster. For new Bangor extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. In Northern Ireland, homes on oil or electric heating can look at air-to-air systems for efficient warmth.
Prices in County Down
In Northern Ireland, our guide range for air conditioning for new builds and renovations is £365–£795 per indoor position (first fix), including VAT. That sits a little below the UK middle, reflecting typical Northern Ireland labour rates. What moves a quote in County Down up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the First and second fix option (complete install priced per room including units) would typically be £1,345–£2,695 here.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Working with your builder
On build projects the main thing is timing with your builder and electrician; we fit first-fix pipework before plastering and agree the outdoor unit position early.
