Decades of Quality Service

Our company started in 1962 as Phil’s Refrigeration. The parents of current owners Tom and Ken Pavlik purchased the company in the 1980s. Tom and Ken then bought the company from their parents in the ‘90s and transformed it from a new construction company into a service replacement company, rebranding the business as Pavlik Brothers.

In 2011, Pavlik Brothers merged with an Illinois company, Aero Froze Heating and Cooling, which was also started in 1995 with a focus on residential add-ons and replacements. The newly merged company then purchased Alliant Energy Security Blanket®, a service and maintenance program with nearly 8,000 clients.

We specialize in designing, engineering, and installing complete comfort systems for local homes. We’re proud of the technicians we employ and train. Our customers are grateful to have such stellar people offering an honest and friendly approach to every job. It’s our goal to give our customers a hassle-free experience, and we promise that if you’re ever unsatisfied with our services, we’ll do everything we can to make it right.

Your complete satisfaction matters to us, not just trying to protect our company image. This philosophy is one of the reasons we continue to grow, adding more satisfied customers each year.
