Customer Reviews

"Our furnace went out on a Friday night in January. New Lenox Heating had a tech at our door within 2 hours. Fixed it the same night. Incredible service — I can't thank them enough. Will absolutely use them again."

"I've used them for 15 years. Always honest, always fair pricing. They told me my old furnace was still repairable when another company wanted to replace it. Saved me $3,000. That kind of honesty is rare."

"Had them install a new AC system last spring. The crew was professional, clean, and finished on time. Our energy bills are noticeably lower. Highly recommend New Lenox Heating to anyone in the area!"

"After getting quotes from three companies, New Lenox Heating was the most straightforward. No pressure, no upselling, just honest advice about what we needed. The installation was flawless."

"Been using New Lenox Heating for annual furnace and AC tune-ups for 8 years. They're always on time, thorough, and reasonably priced. Haven't had a breakdown in all that time. That says it all."
