Costello Heating & Air Conditioning

Costello Heating & Air Conditioning has served the Eastlake community with round-the-clock availability, maintaining a 3.6-star rating across 25 customer reviews. The company provides heating and cooling services to homeowners throughout the Lake County area, including nearby Willowick, Wickliffe, and Lakeline. Prospective clients can reach the office at (440) 951-5561. Reviewers consistently mention the team handles both residential furnace and air conditioning installations, with several customers noting same-day service responses during heating and cooling emergencies.

Customer feedback reveals a contractor that competes aggressively on pricing, with multiple five-star reviewers noting Costello provided estimates several thousand dollars below competitors. The technicians who responded to service calls, including Anthony, Harold, Gene, and Matt, received commendations for professionalism and technical competence. However, two one-star reviews highlight concerning patterns: one customer reported a diagnostic error where disconnected wires were mistaken for major equipment failures, and another described an incomplete thermostat installation with no follow-up despite multiple scheduling requests.

Named technicians appear throughout the positive reviews. Gene and Matt earned praise for replacing a hot water tank with honest pricing and efficient work. Anthony and Harold were recognized for same-day furnace motor replacement during a winter emergency. Linda Layton noted the team completed both heating and air conditioning installation in a single day after providing the lowest bid among three competitor quotes. The negative reviews center on diagnostic accuracy and project completion consistency rather than pricing or basic technical ability.
