Cardinal has been taking care of Wisconsin homes since 1984, and in that time we have built something most home service companies cannot offer, which is heating, cooling, plumbing, and electrical work handled by one team under one roof. When something goes wrong, you are not starting over with a new contractor and a new set of strangers, you are calling the same company that serviced your furnace last winter. That consistency is what our neighbors keep voting for. Cardinal has been named Best of Sun Prairie eleven years running, earned Gold in Best of Madison 2025, and been recognized in the Madison.com People's Choice awards twenty-five times. We are BBB accredited, and we hold ourselves to a standard our team knows by heart, do what is right. Our technicians are trained to explain the problem before they fix it, so you understand what is happening in your home, what it will take to make it right, and what your options are. That is how we have earned repeat customers for four decades, and it is why our team works their tails off on every call.
