Leiber Heating & Air Conditioning has been serving St. Charles County since 1992. Founded on a simple service motto — treat others the way we would want to be treated — Leiber HVAC has always focused on adding real value to every repair, service call, and installation.

That philosophy of helping customers get the most comfort for the fewest dollars has kept Leiber HVAC busy for more than 30 years, serving many of the same original customers while welcoming new families and businesses along the way.

Today, that legacy continues with the recent transfer of ownership from founder Karl Leiber to his son, Jonathan Leiber, and son-in-law, Mike Vincent. While leadership has passed to the next generation, the values, workmanship, and commitment to honest service remain exactly the same.

Low overhead, deep technical expertise, and a practical understanding of an ever-changing HVAC industry continue to keep Leiber HVAC at the forefront of comfort solutions in St. Charles County.

Karl and his wife, Angie, are lifelong St. Charles residents — both born, raised, and educated here. They still live in the home Angie grew up in, just seconds from McNair Park, a reminder that Leiber HVAC has always been, and will remain, a true hometown company.
