"I purchased a new HVAC system from Cardinal. Everything about the job went as planned, in the amount of time we were promised. The installers were professional and cleaned up the work space very well when they were finished. I would use Cardinal again without hesitation."

"Ben was originally a sub contractor for an addition to our home in Highland, WI. He installed new duct work to the dormer addition, and I retained him for furnace replacement, and, later, addition of a central a/c unit. I appreciated his openness to questions, his attention to detail and his technical knowledge. He is a delightful person, totally devoid of b/s, and fully trustworthy."

"It went great very caring and thorough work. The house looked and smelled amazing. We are having them back to clean the windows inside and out in May. Completely happy with the attention to detail and professionalism. Very personable and willing to go above and beyond our expectations. I’d hire them in a nano second and I’m kinda tough to please."
