Kiernan-Laitinen Heating Puts Your Comfort First

Kiernan-Laitinen Heating & Air Conditioning has been a leading home comfort provider in Racine since we opened in 1992. The company started in the original owner’s basement as Kiernan Heating & Air Conditioning and grew quickly thanks our great service and trustworthy team. Jon Laitinen joined the team in 2000 and became owner in 2009 after proving his HVAC aptitude and impressive ability to lead. The name was updated to Kiernan-Laitinen Heating & Air Conditioning and we continue to offer the same outstanding service today as we did over 30 years ago.

Why We Chose the HVAC Industry

Every team member at Kiernan-Laitinen Heating feels a responsibility to help others, which is why we chose careers in the HVAC industry. Our job is about more than keeping you comfortable—it’s about keeping your family safe. As technicians, we are trained to identify problems, assess dangers, and recommend fixes that are safe and meet industry codes.

To better serve you, we are certified by the Environmental Protection Agency (EPA). We’ve passed an EPA-approved exam and proven our commitment to safely service, repair, maintain, and dispose of certain equipment. We also have North American Technician Excellence (NATE) certified technicians on staff who have passed an exam to demonstrate real working knowledge of HVAC systems, as well as service and installation skills.

Giving Back Is Important to Us

From record hot days and cold temperature swings to 24-hour availability, our team works hard to meet every challenge and keep our customers comfortable. And rewarding them for their hard work is important to us. That’s why we host an annual golf outing, company picnic in summer, holiday gatherings in winter, and other special events throughout the year.

We also give back to our community by backing local sports teams and sponsoring a number of school functions. We don’t just work in Racine, we live here, so if we can help make our city a better place, we will do whatever we can.
