SAN ANTONIO — Two of San Antonio’s top air conditioning and heating companies are merging operations to better serve homeowners in south Texas and the Hill Country. Elmer Zubiate, owner of On Time Elmer, has acquired the San Antonio franchise of One Hour Heating and Air Conditioning. The two companies have merged under the new name of Elmer’s One Hour Air.

“This move allows our companies to help more homeowners stay cool during the hot, Texas summers,” said Zubiate. “We’re really excited about the possibilities.”

On Time Elmer has a long history of philanthropy in the San Antonio area that Zubiate said will continue under the Elmer’s One Hour Air name. The company is a major supporter of Komen San Antonio and the fight against breast cancer. In fact, On Time Elmer was known for its pink trucks. It’s a mission close to Zubiate’s heart; his mother died from cancer in 2008.
