Our story
I grew up in the Salt Lake Valley. Same winter inversions, same July heat, same furnaces and swamp coolers in the same neighborhoods you live in. In 2015 I started I Know A Guy HVAC to be the company I'd want to call: local, honest, and quick to pick up the phone.
Now I'm raising my own kids here. Every job we take is for a neighbor, and we treat it that way. It pays to know a guy.
