New build and renovation air conditioning in Johnstone
First-fix pipework in Johnstone extensions goes in while the joists and studs are open. In central and southern Scotland, heat pump heating is usually the main reason to install, especially in homes on electric heating.
For new Johnstone extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Johnstone sits around 3 miles from Paisley, inside our Renfrewshire and Inverclyde area. We cover PA5 and the streets around them.

That sits a little below the UK middle, reflecting typical Central and Southern Scotland labour rates. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure.

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
We book surveys in Johnstone at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
