Recent Google Reviews

  • Alfonso Barrientez5.0We have been doing business with Zimmerman A/C for 40 years. We started with the founder Larry Zimmerman honest, hardworking, and a true craftsman. His son Luke carries on his legacy. They recently replaced a unit for us their crew arrived put down tarps covering the walkways they were using and installed the unit on a very hot September day. Afterwards I saw them vacuuming the whole walk way even though it had been covered I told them they didn’t need to do that as they had been up in the heat of the attic all day his response “it’s part of the job sir!” Also Carla in their office worked the schedule to get the install done sooner as we were expecting a visit from our kids. Quality American Standard products, honesty and craftsmanship (the unit they removed was put in by Larry, Luke’s Dad 19 years ago!) Great people I highly recommend them and won’t let anyone else touch my HVAC systems!September 2026Google
  • K. Leigh1.0Spent over $15,000 and they didn’t install our AC unit correctly. We’re having ceiling leaks and water dripping outside our house. They put the drainage through our sink, which I believe is against state regulations. When there is a storm, our AC quits working for some reason because of the rain. It has caused extensive damage to my house. This is what happened to the ceiling— 4-6 years after the improper installation.September 2026Google
  • Kevin Ryan5.0Annual service. As usual, the expert attention to detail helps me to keep my HVAC system running smoothly, efficiently and reliably.September 2026Google
  • Elizabeth Napier5.0I love the assurance of having very skilled and professional people work on my air-conditioning units! Caleb with Zimmerman air-conditioning did an outstanding job of maintaining the units, explaining any findings, and then relaying options to me to make my units even better. He was very polite and well spoken.He’s a true asset to Zimmerman AC and I will be requesting him for our next maintenance visit next spring! Thank you Caleb! You deserve a raise!September 2026Google

About Zimmermann Air Conditioning & Heating

Zimmermann Air Conditioning & Heating has been family owned since 1989, giving the company more than three decades of history serving San Antonio from its location on Mainland Drive. The company specializes in the installation, maintenance and repair of residential heating and cooling systems.

Zimmermann is listed as an authorized American Standard dealer, a designation the manufacturer reserves for dealers meeting specific training and customer service standards. That relationship gives homeowners a manufacturer-backed point of reference when comparing installation quotes, particularly for anyone already set on American Standard equipment.

The company has built a 4.9 star average across more than 1,100 Google reviews, a strong volume for a family-owned operation that has stayed independent rather than expanding into a multi-branch regional chain. Zimmermann's own marketing emphasizes superior customer service and the integrity behind its work, framing the company's mission as helping families feel comfortable and safe in their homes rather than simply completing transactions.

What is less clear from publicly available information is a specific Texas contractor license number and defined warranty terms for new installations, since detailed program information was not available at the time of this review. A homeowner comparing quotes should ask Zimmermann directly for its Texas Department of Licensing and Regulation license number and the specific warranty coverage on any new equipment before signing.

Anyone hiring Zimmermann, or any HVAC contractor in San Antonio, should verify the technician's license number with the state before approving work, and should get exact warranty terms in writing.
