Zimmermann Services Zimmermann Air Conditioning and Heating was established in 1989 by Larry and Pati Zimmermann with big dreams and a few dollars. Larry came from a hard-working background, raised on a farm in South Texas, his responsibilities ranged from picking cotton to working on machinery and tractors.

He was no stranger to work and these ethics preceded him in every aspect of running his own business, from taking calls late at night, to waking up at the crack of dawn so that he could get a head start on the work day.The dream of owning a successful business and providing a higher level of customer service was quickly becoming reality for Larry and Pati.

Before choosing Zimmermann I received several quotes. However, after speaking with Trey and the recommendations from friends we knew whom we should choose. I was very impressed with the install crew. They were extremely courteous and respectful of the property. They always made time during the install to answer any questions or concerns I had even though we had quite a complex install. The support I have received after the sale has been excellent. Their team is quick to respond and that has been a load off my mind.

When our A/C suddenly stopped working on a 100 degree day after work we needed after hours help fast. I was lucky to find Zimmerman because in under 1 hour our repairman arrived. We ended up needing a new capacitor which was replaced. Prices were transparent and our repairman was honest about what we needed. No pressure sales. Both the service and our interactions with our repairman were professional, friendly, and very pleasant. We also purchased the service plan and are very happy. Thank you. I definitely recommend their business.

Had a third party come from Best Buy to install new thermostat and they ended up blowing the ac an thermostat. Zimmerman was able to send out the same afternoon, on a Saturday. Omar was very friendly and professional. He diagnosed and fixed the issue quickly. He then spent several minutes explaining the features of our thermostat and preventative maintenance. House was cool and wife was happy. Thank you!

Quick response to an inoperable AC. Scheduled a time for repair and then called with an opening to come well in front of scheduled time because they had an opening. Stevie came for repair. Stevie was knowledgeable, kind, honest and repaired exactly what we needed in under an hour without any crazy upselling I have experienced with other AC companies. Great communication. Reliable. Honest. I am a realtor and have used Zimmerman several times for listings. Will continue to use personally for my own home.

When we realized we needed A/C servicing, we began our footwork. Zimmerman's A/C & Heating did not disappoint. They live up to their stellar reviews! Terry and Trey provided visuals, for all you "This Old House" peeps, like myself, and answered all of our questions. After deciding on the appropriate systems for our home, Michael came out with the installation crew and installed our new systems within a couple of days.

Can't forget to mention Tracey's quick and great office fulfillment with paperwork and scheduling! It's very refreshing to find an honest company that you can trust. Thank you Zimmerman AC & Heating!

First we were impressed with the Zimmermann sales person; he seemed knowledgeable but also down to earth and fair, willing to work with us a little on price which is more than other companies would or could ever do probably due to their strict corporate structure. Most importantly though, the Zimmermann price for the system we ended up purchasing was literally thousands less than other companies but for a far superior unit!

Something that just doesn't happen much these days. We know that Zimmermann is a strong family-owned company. This was evident once the installation crew started working. They were professional but also kind and considerate. They went out of their way to honor a request we had about one of the pipes, something we know big corporate companies would not be able to honor.

We know because we had a system from a big corporation prior to Zimmermann and that company ran in a rigid and robotic way. The Zimmermann crew was a pleasure to deal with during the installation. Taylor, the lead crew member, was absolutely fantastic! So enthusiastic, very knowledgeable, and appreciative. And of course, the new system works perfectly, we're very happy with it and with Zimmermann; the kind of company we all wish for these days. We would recommend Zimmermann sales, products, and employees to anyone looking for the best HVAC systems (American Standard is a brand we trust!) in San Antonio.

Bar none The Best. Just happened to see the Zimmerman van when one of my tenants needed emergency service. In every aspect they took my sense of urgency as serious as if it were their own issue and the responsiveness from the Office folks to the Techs, never waned. The professionalism, communication, attention to detail and right pricing stood out.

As a real estate investor experienced with various local companies, Zimmerman is the best. No one else comes close for my properties. Do yourself a favor, you'll be glad you chose Zimmerman AC.

Excellent customer service all around. Friendly dispatcher and the technicians have been very professional and honest. I have used Zimmerman twice, once to diagnose and change a condenser, and then again during a freeze when my heat went out. The technician got my heat working again and because it was a simple solution, did not charge me for the visit. This is my go to a/c company from now on.

Zimmerman did an excellent job in assisting us with our heating issue. Stevie the repairman was very knowledgeable courteous and honest. Other ac companies wanted a maintenance agreement before they would show up (air tron). I highly recommend Zimmerman for your heating and AC needs. Service: Heating system maintenance

Finally had to replace my ac system and Zimmermann was an easy choice! Everyone there was polite and professional from the office, to Trey our salesman, and at the end with the install team. I couldn't be happier. Thanks again!

We have used Zimmermann Services for all of our air conditioning, heating and plumbing needs for approximately seven years, since we stopped renting out our San Antonio residence.

Having Albert from Zimmermann inspect my air conditioning and heating unit was a great experience. I have an old unit but Albert didn't find any problems with it and he gave me the peace of mind that my equipment is working fine. He was very patient and answered all of my self maintenance questions and made sure I understood what I needed to do to keep my unit working optimally.

Noticed (83 Degrees and rising inside) A/C (outside unit) wasn't working. Called at 2:00pm (Labor Day). Albert, who was on call, arrived at 3:00pm. Replaced capacitor, checked out rest of the system and was complete by 3:30pm. Quick and responsive service. Just charged for service call as the rest was under warranty. Have used Zimmermann Services for going on 20 years now.

I recently had AC problems in June. A local company that actually installed it had come out at least 4 times in 1 year and still I was having problems. They wouldn't return calls, it was a horrible experience. I decided to call Zimmermann, Albert came out diagnosed the problem right away and it was completely fixed the next day and I haven't had any issues for the past month.

I am extremely satisfied with the services provided by Zimmerman. I recently had my A/C serviced by technician Jason who was prompt, personable and very professional. I have used Zimmerman Svcs for several years including a major sewer line repair (to fix a line break caused by another plumbing company) & have been pleased with the all the services provided.

After San Antonio's first really cold night of the year, it was obvious my heater was broken. With a Hospice patient in the house, it was critical that we get the heater fixed quickly. Mr. Zimmermann and his son, Luke, worked tirelessly to assess the situation, get the parts, and get it fixed--on what was arguably the busiest day of the winter for them thus far.

Recently my A/C went out and as you might imagine in San Antonio in the middle of July it can get rather hot, as a matter of fact this week triple digits. We had a company come out that I used before and they told me that my compressor was out.
