New build and renovation air conditioning in Renfrew
Mild Scottish summers mean cooling matters most in conservatories, lofts and rooms with large windows. Renovations in Renfrew are the easiest jobs to make invisible, because the pipework goes in before the plaster.
For new Renfrew extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Renfrew sits around 3 miles from Paisley, inside our Renfrewshire and Inverclyde area. Postcode districts we cover here include PA4.
Prices in Renfrew
Our Central and Southern Scotland guide price for air conditioning for new builds and renovations is £365–£795 per indoor position (first fix), VAT included. It is a touch below the UK middle, as trade rates in Central and Southern Scotland tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. Typical First and second fix work (complete install priced per room including units) lands around £1,345–£2,695 in this area.

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.
The survey

At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
