“I called Kulacz & Sons for a second opinion. Not only did I not need a new furnace as recommended by another company, they ordered and installed the parts needed the very next day. Definitely earned a lifetime customer. They work with honor and integrity. The technician Ozzie was very patient, courteous and professional.”

"Our service technician was extremely nice and helpful! 10/10 would recommend if you need service or maintenance on your furnace. He taught us a lot about our furnace and made sure we didn’t have any questions before he left. Very thorough."
