Lanigan

Lanigan Heating and Air Conditioning operates from 1869 E. 337th Street in Eastlake, Ohio, serving residential and commercial clients throughout Northeast Ohio, including communities near Lake Erie and the Cleveland suburbs. The locally owned and operated company has earned a perfect 5.0-star rating across 462 reviews on Google, reflecting consistent customer satisfaction in a competitive HVAC market. Founded and led by Dan Lannigan, the company holds appropriate licensing for Cuyahoga County and performs installations, repairs, and maintenance for all major heating and cooling equipment.

What distinguishes Lanigan from neighboring contractors is the depth of its written guarantees and its approach to transparency. The company promises a full refund if a technician curses, smokes, or fails to use floor protectors in a home. It also pledges that repairs completed within the first year will be re-performed at no charge if the fix does not hold, and that new equipment must actually heat or cool the home to the customer's satisfaction or the entire investment gets refunded. These guarantees appear on the company's website alongside a Comfort Club membership program for scheduled maintenance, suggesting a focus on long-term client relationships rather than one-time service calls.

Customer reviews name specific technicians and describe particular situations that illustrate how the team responds under pressure. One reviewer noted that when their furnace died, Dan returned the call within hours even though the homeowner explained his wife was undergoing chemotherapy treatment and needed warmth immediately. Another customer reported a furnace over 20 years old received same-day replacement after calling around noon. Three workers appeared in multiple reviews: Will performed the installations, Fredo served as lead installer, and Zack handled service calls. Megan in the office coordinated scheduling and ensured estimates were delivered promptly.
