O'Donnell Heating & Air Conditioning Inc - Buffalo

O'Donnell Heating & Air Conditioning Inc has served Buffalo-area homeowners since establishing operations in Western New York. With 436 client reviews generating a 4.7-star average rating, the company has built its reputation on honest recommendations and quality installations. The business operates around the clock, seven days a week, ensuring residents of Buffalo and surrounding Erie County communities have access to emergency heating and cooling support when they need it most. Owner Jim O'Donnell remains hands-on with estimates and installations, personally engaging with homeowners to assess their heating and cooling needs.

The company holds dealer partnerships with Lennox, supplying residential customers with furnaces, air conditioning systems, and water heaters. Tyler Ostanski's review specifically notes his Lennox furnace installation was handled by courteous installers who returned within 30 minutes when he had a follow-up question the next day. This responsiveness exemplifies the company's commitment to post-installation support. The 24/7 availability distinguishes O'Donnell from contractors with limited weekend or evening capacity, particularly valuable during Buffalo's extreme winter temperatures when furnace failures create urgent situations.

Michael Buscaglia experienced this firsthand when he woke to a freezing house on the coldest day of winter and called O'Donnell at 8am, the company dispatched a technician within the hour. Jon Klaybor's review describes how a friend's recommendation led him to Jim O'Donnell, whom he found to be 'more genuine and honest' than typical contractors. His crew replaced his A/C, furnace, and hot water tank in a single project. The office staff, particularly Dawn, earns consistent praise for helping homeowners navigate estimates and find workable solutions, as L.G. noted when the owner adjusted the original quote after discovering a second furnace was needed.
