Mr. Erwin Inc.

Mr. Erwin Inc., founded in 1982, is a family-owned HVAC contractor operating under Texas license TACL B10555E. Owner Erwin Lehmann, Jr. built the business from a north-central San Antonio base at 1008 Beckett Road, expanding service across Bexar, Kendall, and Comal counties. The company holds a 4.7-star average across 39 verified reviews, reflecting nearly four decades of consistent customer satisfaction in residential and light commercial climate control.

What distinguishes Mr. Erwin Inc. is their equipment portfolio and technical infrastructure. The company installs American Standard systems, recognized for innovation in variable-speed technology, alongside Mitsubichi Electric's ductless STAR lineup offering zoned comfort without ductwork. Their Honeywell air quality solutions address indoor pollutants common to South Texas homes, complementing the cooling systems. An in-house design and engineering department handles custom load calculations and duct fabrication, rather than outsourcing blueprint work, a resource few residential contractors in the San Antonio market maintain.

Customer reviews name specific technicians handling urgent situations. Martez completed an efficient diagnosis and repair for Annette Beck, arriving as scheduled despite prior relationships with the company spanning years. Pat Garza requested same-day service when cooling failed on a Friday; Santos performed extended troubleshooting into evening hours, later revealed as a 41-year company employee. Clay S. credited technician Tom with resolving a new Google thermostat integration during a cold front arrival, requiring only one service call to restore heating after the system replacement originally completed by Sonny Erwin exceeded a decade prior.
