About Us

Who Are We?

Grant Air was established over 20 years ago by our Managing Director, Tony Grant. Since then, the company has gone from strength to strength; we’ve expanded our team and successfully installed air conditioning, HVAC, and ventilation units nationwide.

What We Do

We specialise in the installation of commercial and retail air conditioning , ventilation, and HVAC systems. Our high-street clients include household names such as JD Sports, Size?, Carhartt, Jo & The Juice, and Jack & Jones.

Thanks to the experience and knowledge of our skilled team, we’re able to offer clients a bespoke service, with solutions that solve a range of logistical challenges. For example, we were able to organise a road closure to facilitate an extensive fit out on a large JD Sports store in Stirling.

Our work has seen us fulfil numerous large-scale projects across various sectors, including:




Office Blocks


Shopping Centres




Retail Stores

Although our primary focus is commercial fitouts, we also carry out domestic installation work.
