“We recently purchase a home in Sun Prairie and discovered a leak in our water softener due to a fault unit. We contacted Cardinal Heating and AC about the issue and they were AMAZING! They were a pleasure to speak on the phone. They came the same day and like promised gaves us a courtesy call prior to arrival, Brandon was our technician. He was very knowledgeable, efficient and friendly. Hands down a wonderful experience. They are now our go to provider for any future heating/plumbing issues. Thank You!”
