Our Story

Founded in 1987 by Ramon Blachly, One Hour Heating & Air Conditioning of Johnson County began as a family-run business built on honesty, respect, and a commitment to customer care. Starting from a basement office with his wife Janet handling operations and Ramon going door-to-door, the company quickly earned a loyal following. After acquiring Olathe Heating and Cooling and growing steadily, the business transitioned into a One Hour franchise in 2004, aligning with values of convenience, courtesy, and integrity.


Now a second-generation company led by son Jonathan Blachly, One Hour Heating & Air Conditioning continues to prioritize innovation and excellence. With numerous awards for customer service and operational performance, including multiple Top Net Promoter and Angie’s List Super Service honors, the team remains dedicated to “impressing the socks off” every customer. From humble beginnings to a thriving local business, their mission is to serve families with the same care they’ve shown since day one.
