About us

S. J. Kowalski, Inc. has been serving the heating, air-conditioning and plumbing needs of the greater Hazleton and surrounding areas since 1972. We install high-quality equipment from today’s industry leaders like Trane, Mitsubishi, Rinnai, Honeywell and Triangle Tube while providing “round-the-clock” 24 Hour Emergency Service. We are a family owned and operated business and the area’s only Trane “Comfort Specialist” dealer.

It's important to get ready for the upcoming Winter season, getting your repairs and necessary services out of the way early will save you money and peace of mind in the long wrong. If your furnace, Mitsubishi mini split, boiler or heat pump breaks down mid winter that's a big problem. We provide expert service and preventative maintenance to make sure this doesn't happen.

At SJ Kowalski Inc we are committed to providing the best products and solutions to help lower your energy costs and keep your family safe and comfortable.
