About Us

Mr. Erwin Inc. is owned by Erwin Lehmann Jr. and has been family operated since 1982.  We have been providing San Antonio, Texas with quality air conditioning installation and service since 1982.  We are conveniently located in north-central San Antonio and provide service throughout Bexar, Kendall and Comal counties.

We have been equipping new homes with outstanding home comfort systems for quality custom home builders since 1982. If a builder demands the best in quality and homeowner satisfaction you will find Mr. Erwin Inc. installing the air conditioning and heating system in the homes they build.

A home comfort system is only as good as the installation of the equipment and the air distribution system. The most efficient system on the market today can be severely inhibited by a poor installation.

Mr. Erwin Inc. does not subcontract any phase of the construction or installation or service work that we perform. Our on staff team of professional tradesmen take great pride in their work. We are completely licensed, bonded and insured for the protection of the builder and the homeowner.

We are proud to be dealers of the finest air conditioning and heating equipment on the market today. We offer three lines of equipment to provide a variety of choices that can cover the needs of every customer.

Mr. Erwin Inc. takes great pride in the quality of our work and the equipment provided by the manufacturers. For more information contact us today.

We will be happy to answer any questions or to meet with you personally to discuss the options available for your new or existing home.
