Jason Giandalia
Owner of Gray Duct Heating, Cooling & Air Duct Cleaning. Born and raised in Minnesota, Jason brings the same service, energy, and passion to every Gray Duct job. Customer service is his top priority.
I started Gray Duct Technologies because I was tired of seeing homeowners get overcharged for work they didn't need. We do things differently — and we always will.
