LR Gregory & Son

Founded in 1952, LR Gregory and Son has operated as a family-owned HVAC contractor in Lake Bluff, Illinois for over seven decades. The company holds licensure for heating, air conditioning, gutters, sheet metal work, and roofing, serving Lake County and Cook County communities throughout the north shore region. Across 17 verified client reviews, the business maintains a 4.5-star average rating, reflecting consistent service delivery in residential heating and cooling systems. The company stocks equipment from leading manufacturers including Rheem, Lennox, Carrier, Bryant, and Trane, enabling single-visit replacements without special-order delays.

The company operates as a certified dealer for multiple tier-one HVAC manufacturers, streamlining warranty coverage for homeowners. Their in-house sheet metal fabrication capability allows custom ductwork modifications during installation, reducing project timeline dependencies on third-party shops. Technicians undergo manufacturer-specific training on variable-speed systems, addressing the efficiency requirements of modern high-efficiency equipment commonly installed in northern Illinois homes.

Customer experiences highlight technicians Steve, Drago, and Reese by name for resolving complex system failures. Multiple reviewers describe same-day response during extreme cold snaps, with one client noting a thermostat communication failure with their furnace was diagnosed and corrected the following day. Another recounted Steve addressing dual-furnace systems with future consideration planning, while Drago completed a repair change at no additional cost despite encountering unexpected complications. Owner Jim Gregory personally conducts follow-up visits to verify customer satisfaction on larger projects.
