Zimmermann Air Conditioning & Heating

David and Omar were extremely knowledgeable and professional. Both gentlemen explained every service provided and even encouraged me to observe the work performed. They did more than I expected and for a reasonable fee. They also guaranteed their work and asked me to call them if there were any other issues abd they would not hesitate to come out. They were both friendly and polite.

This company is hands down the best! My AC wasn’t cooling the house and I have little ones and so the stress was high because you don’t want everyone in the house have to sit in a hot south Texas heat. They came by and took that load of stress off of me. Zimmerman are truly people who care for their customers. Other AC companies have come by in the past and only put a bandaid on the problem and never once guided me along of the true problem I had. Don’t miss this opportunity to use these guys the next time you need AC help.

Thank you Terry and Michael for coming out and running a check on our A/C! They were thorough, pleasant, professional and honest. I appreciate a company with ethics! It makes a world of difference! I am so glad our A/C is working! I also appreciate David who is on call and came by after office hours. Zimmermann A/C and Heating is the company to call!

My A/C picked a Saturday to stop working and after calling a few places Zimmermann answered and were able to come out. They diagnosed the problem, gave me a few options for repair, but were not pushy at all. Since it was old anyway I decided to get a whole new HVAC system. They gave me a fair price and the installation was very thorough and even did a follow to make sure everything was good. I went ahead a signed up for these guys to due the regular maintenance, highly recommend Zimmermann A/C and Heating.

I absolutely had the best customer service with this company from beginning to end. They scheduled us in promptly, arrived on time, terry was able to figure out the issue and fix it with ease. Now we get to enjoy our cool air during these hot summers.

Zimmerman AC was extremely professional from beginning to end. Booking was simple, with confirmation before appointment provided electronically and by telephone call. Trey even called to see if he may arrive early. He was friendly and professional. He spent 7 hours at our home, extensively going through each unit. I appreciated how he took time to make sure the job was done well. He was extremely conscientious with cleanliness, wearing booties each time he came in the house, and vacuuming debris from opening the attic. He spent quite a bit of time going over his findings with us and explaining the meaning and possible options to keep our AC running smoothly. Overall great professional experience. Highly recommend.

Fantastic experience! My tech (David S) showed up on time, and he was friendly and professional. He helped me diagnose the issues with my furnace/condenser and gave me options without pressuring me into anything. I got a honest diagnosis, on time, for a great price. Definitely using Zimmermann from now on!

We were loyal customers of another HVAC company for over 13 years until they started nickel and diming us. We decided it was time to cut ties and go elsewhere. We definitely made the right choice with Zimmerman. They were prompt in their service call, holistic in their approach, and honest in their pricing. The crew arrived on time, stayed focused on the project and executed amazingly! We are now loyal customers of Zimmerman.

For reasons unknown to me my thermostat kept resetting itself, I did not think anything of it, I thought it needed a battery replacement, no Biggy. Then one day my AC/heating system went out. I heard a clunking sound and a bang, then it stopped working. I called Zimmerman Air Conditioning and Heating. They gave me a same-day appointment. They were upfront with the cost for them to come out and give me a repair estimate. I had a bad thermostat; my blower motor went out and I had a damaged blower wheel assembly caused by a previous electrical surge and repairs. I had no clue what just had happened to my AC/Heating system, Dave the technician took his time and effort to help me understand what all that had gone wrong with my system. I was feeling hopeless and unsure about everything, but Dave answered all of my questions and concerns. I was very pleased and thankful that he was so helpful. They were so thorough that the owner Terry came out, and he was great, he reassured me that I could be confident in their work and the quality of the replacement equipment that they utilized. Terry the owner meant business he had Max bring the replacement parts, making the work that needed to be done quickly and very efficient. The company is very much invested in giving back to the community and has a special program available to clients in need of services with financial restrictions, I was able to utilize the program. I was so impressed by Zimmerman’s services, I never write reviews, because they are qualified professionals, but I had to. My system is now working fine, I am so happy with my AC/heating system. I highly recommend their services.

The absolute best is San Antonio. I used three other companies before Zimmerman and is hands down the best at what they do. In fact, I had them replace my old systems and I could not be happier with the result to include lower electric and gas bills, and and a cleaner house. This company takes pride in what they do and taking care of you as a customer.
