Beyond the Blueprint

A division of Ambient, Gil-Bar is the HVAC solutions company that offers greater engineering expertise, with deeper commitment to your success, than any other firm.

We believe HVAC is about a lot more than moving air.

It’s about creating places where we can live our best lives and do our best work. It requires understanding the total indoor environmental experience, and providing optimal thermal and acoustical comfort. And we know that doing so, efficiently and sustainably, is an ever-greater engineering challenge.
