Cardinal Heating, Cooling, Plumbing & Electric is dedicated to providing the best plumbing, electrical and indoor comfort solutions for your family. Since 1984, we have installed and repaired countless HVAC systems and more recently have added plumbing and electrical services to better meet the needs of our customers. Among Sun Prairie homeowners, we’ve earned the reputation for getting the job done right the first time! Every job is tailored to your specific situation and budget. We start by asking questions. If you experience less-than-satisfactory service, we haven’t done our job properly. Each one of our technicians has completed rigorous training (and continues to complete advanced training regularly). This means we are able to complete the repair or installation job to high standards, ensuring your peace of mind. We also provide service plans to keep your HVAC system operating at peak efficiency. It’s all part of our tradition of delivering top-notch service.
