For over 30 years, Siemer Heating & Cooling has been providing top-quality heating, ventilation, and air conditioning (HVAC) services to homeowners in Highland, IN, Schererville, IN, Munster, IN, and the surrounding areas.

Our History

Siemer Heating & Cooling was founded in 1987 by George Siemer, a true problem solver who worked with some of Chicago’s leading HVAC companies for over a decade. He learned his trade by doing hands-on work—day in and day out.

George worked with steam heat, forced-air natural gas units, and everything from window air conditioners to residential central air—all the way to huge commercial heating and cooling systems.

Early on, it became clear to him that providing top-quality HVAC equipment for customers was essential to good service. That’s why Siemer Heating & Cooling only offers top-of-the-line residential and commercial HVAC products.

Today, George's two sons, Paul and Alan, now own and operate the family business. Siemer Heating & Cooling continues to focus on providing customers like you with the best indoor comfort systems at an affordable rate. Our company is built on the principle of trust, and we intend to keep it that way.
