Lockwood Furnace Company

Lockwood Furnace Company has kept Joliet-area homes warm and comfortable since 1932, making it one of the oldest continuously operating heating contractors in the Greater Chicago region. With a 4.8-star average across 280 customer reviews, this family-run business has earned a reputation for transparent pricing and technical expertise. Based in Joliet, the company serves surrounding communities including Essex and Yorkville, offering both residential and light commercial HVAC solutions. All technicians maintain current certifications, and the company operates around the clock seven days a week to handle heating emergencies whenever they arise.

What distinguishes Lockwood Furnace is their "repair before replace" philosophy, which saves homeowners money by extending the life of existing equipment rather than automatically pushing expensive new system purchases. The company offers seasonal A/C tune-ups designed to prevent mid-summer breakdowns and maintain efficiency throughout cooling season. For customers needing new equipment, Lockwood provides 0% financing on top brands Trane and Amana, along with free in-home estimates. This approach of educated recommendations rather than high-pressure sales resonates strongly with reviewers who appreciate having honest options explained without obligation.

Customer feedback consistently names specific technicians who delivered exceptional service. Reviewer Tim Lepucki described a two-day installation where Andy and Zach arrived promptly, kept the workspace clean, and even corrected previous installation errors to optimize the new system's efficiency. Wayne Kassel praised the thorough explanations provided during his furnace replacement, with an estimate arriving within two hours of his initial call. Multiple five-star reviews highlight the team's honesty, respect for homes, and fair pricing, qualities that have grown almost exclusively through word-of-mouth recommendations in a community that's known them for generations.
