Legacy Heating & Cooling

Legacy Heating & Cooling operates from Libertyville, Illinois, delivering residential and commercial heating, air conditioning, and refrigeration services across Lake County. The company holds active licensing as a licensed, bonded, and insured contractor, with a perfect 5.0-star average drawn from 171 client reviews. Owner Mitchell Moore leads a team of in-house and factory-trained technicians who handle everything from routine furnace tune-ups to complex commercial refrigeration systems. The business maintains round-the-clock availability, ensuring no customer endures a malfunctioning system through night or weekend.

What distinguishes Legacy Heating & Cooling is their commitment to transparent diagnostics without aggressive upselling, a practice repeatedly praised in customer feedback. The company offers comprehensive air quality solutions including purification and humidification systems alongside traditional heating and cooling equipment. Their commercial refrigeration expertise serves businesses needing specialized cold storage maintenance, a niche that separates them from typical residential-only contractors. All service calls receive the same thorough approach: combustion safety testing on heating equipment and detailed explanations of any recommended repairs.

Customer stories dominate the review history, with technician Mitch Moore arriving at Jo Ulshafer's home first thing in the morning after her furnace failed overnight. When Sheila Ottens' furnace developed a mind of its own, Moore performed a full inspection, cleaned a sensor, and restored the unit to like-new performance. Dan O'Brien made a house call at 8pm on a Friday night for Julie Walker, diagnosing and repairing her non-functional furnace within minutes. Connor from the team prepared an entire new home's heating system for winter, walking the homeowner through the system's quirks and maintenance needs.
