"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."

"We had Shawn come to our home to install a ceiling fan in our living room with a raised ceiling. He was very kind, courteous, honest, and very professional. He knew what he was doing and made me feel assured of the quality of his work. One catch though is that WireOne has an initial dispatch fee and then works off of a standard pricing sheet so my particular install got quite expensive. The pricing sheet covers almost any imaginable service/job and scenario that they could do but definitely seems to favor them (probably factoring in most time expected to complete the work, worst case in supply cost, etc.); but as a customer you know upfront exactly what the cost will be and can choose whether to do it or not. They offer great quality work and you know they're doing everything right, but you may end up paying for it depending on the service/job that you're looking for."

"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."

"Adam and Pat do amazing work. They have been doing any work on the house we need for many years now. Most recently they fixed an internal sliding door which came off its tracks as well as installing handrails on the outside steps of our house. We would highly recommend Adam and Pat for any jobs you need completed."

"Incredible friendly service. Brian answered my inquiry within seconds of asking for a professional. Needed help on cold night when furnace could not heat past 55 degrees. Brian was at the house in under 30 minutes, diagnosed and solved the problem and left us warm and cozy! Very reasonable after hours immediate service! Would highly recommend!"
