Mr Erwin Incorporated

Mr Erwin Incorporated takes care of heating and cooling needs for homeowners across San Antonio Texas. This family run operation has stayed under Erwin Lehmann Jr since 1982 and works out of north central San Antonio to cover Bexar Kendall and Comal counties. They handle full air conditioning and heating jobs using American Standard equipment along with Honeywell air quality add ons and Mitsubishi ductless units. Local weather puts real strain on these systems through long hot summers so the crew stays busy with both fresh installs and fixes on older setups that still sit in many houses around here.

The team handles routine checks preparation for summer use and repairs on older units that break down from time to time. Guadalupe Martez showed up for one regular service call and walked the homeowner through every step while laying out clear options. Michael checked both units at another house and made sure everything ran right for the hot months ahead. Santos cleared a blocked condensation drainage tube that had shut down an air conditioner and got it flowing again fast. The crew schedules quick visits and sends techs who know how to sort out the common problems that hit San Antonio systems.

Customers keep pointing to the quick response times solid fixes and techs who show up ready to explain the work without any runaround. Reviews note how the crew handles older equipment with steady results and keeps things moving even on emergency calls. That record of reliable service and clear communication adds up across the jobs they finish. DIRT Score 2.85 from 10 reviews on Finds.

“My service technician for my routine A/C check was Guadalupe Martez. I want to commend him on the services and manner in which he provided the needed services. He was professional, knowledgeable, courteous and explained everything he did and what was needed and explained options to me as well. The capaciter needed to be replaced. I have been using Mr. Erwin services for numerous years and have always been satisfied with the services provided. This specific service technician was an exemplary employee. Kudos!”

“We highly recommend this company for their thorough service and strong work ethic. Our technician, Michael, made sure both our AC units are ready for summer. We will definitely call on him again.”

“I have been using Mr .Erwin since 2021, and have always been happy with their service!We have older units that require occasional repairs and services, and the Mr. Erwin team always schedules us quickly and gets the issues resolved. All of the technicians have been professional and friendly. I had an issue on a Saturday after 5pm and the weekend call technician helped me troubleshoot some ways to resolve it (I had seen them deal with this before so I was familiar with some options). I am happy to recommend them to anyone needing HVAC services!”

“Been in my current home since 2002 and have been using and trusting Mr. Erwin since day one. My condensation drainage tube on AC was blocked and AC would not run. Santos came yesterday and got things “flowing” again in no time. Highly recommend this company.”

“I needed to replace an aging AC system. Out of several bids, this company provided the best combination of relevance, response time, and price. The equipment was installed on the date promised. Clean-up was good, and my questions were answered; I was pleased with the work and would use them again.”
