Zimmermann Air Conditioning & Heating

After 23 years, my AC unit decided it was time to retire. I contacted Zimmermann and Luke was sent to help me out. Luke was very friendly, professional, informative and answered all my questions. His service was excellent and left me feeling reassured I made the right decision on the replacement unit. Everyone I have worked with at Zimmermann has been beyond helpful and I feel like they truly strive to do the best for their customers.

I am delighted to share my positive experience with Terry. He recently installed a smart thermostat and thoroughly cleaned out my AC components. I couldn't be happier with the results. His professionalism and expertise were evident throughout the entire process. He efficiently installed the smart thermostat, ensuring it was seamlessly integrated with my existing system. He also helped me set up the app on my phone and ensured I knew how to use it. Terry's attention to detail while cleaning the AC components was exceptional, and I noticed a significant improvement in the performance of my air conditioner afterward. I highly recommend Terry for his exceptional service and expertise in air conditioner repair and installation.

From start to finish, their team demonstrated a level of professionalism, knowledge, and expertise that set them apart from other companies in the in San Antonio.

First and foremost, their customer service was exceptional. From the moment I contacted them, they were prompt, responsive, and attentive to my needs. They took the time to listen to me and understand my requirements. Their friendly and courteous demeanor made me feel valued as a customer throughout the entire process.

When it came to the technical aspect, their expertise was second to none. The company's technicians possessed a deep understanding of air conditioning systems and were able to provide maintenance, diagnose, and address potential issues with precision and efficiency. They demonstrated an impressive level of knowledge and proficiency in their work. More so, they went above and beyond to explain the intricacies of the various systems available, helping me make an informed decision that suited my needs and budget without pressuring me to make a decision or go with the most expensive product.

Overall, I wholeheartedly recommend this air conditioning company to anyone in need of reliable, professional, and knowledgeable service. Their expertise, coupled with their commitment to customer satisfaction, sets them apart. I am grateful for their outstanding work and would not hesitate to engage their services again in the future.

A/C stopped turning on and was not sure of the issue. Had water in the drain pan under the coils so knew i needed to contact a hvac company. I took photos of everything and submitted them to Zimmermann ac and explained the situation. I contacted them at 6 pm on a Tuesday night. Terry from Zimmermann immediately responded back to me and asked for my address and if he could stop by later that night to see what was going on. Terry showed up at 7pm that Tuesday night, showed me what the issue was and explained the repairs needed to be done and why the system was malfunctioning. He got the system to run temporarily to get us through the night. Now we are in the middle of getting everything fixed and Terry has given me multiple quotes so I can lay out all the options and cost differences. Will continue review after install this week.

Zimmerman AC did an outstanding job and I would recommend them to anyone. My AC system had a clogged condensate drain pipe and I needed some assistance with clearing it and making sure there were no other issues affecting the system. A work colleague suggested Zimmerman and I could not be happier with the service I received. The technician, Terry, was prompt, polite, and professional. He quickly diagnosed the issue and got to work fixing it right away. Terry also spent time giving me tips and tricks for properly maintaining my system by myself, which I very much appreciated. Terry took the time to make a couple other minor fixes, such as patching up some loose tape on some of the pipe installation and even dug out some loose insulation, which had fallen into my drain pan. The price was very fair and the service was impeccable. I wholeheartedly recommend Zimmerman AC to anyone looking to fix an HVAC issue without getting taken advantage of or getting poor service. Zimmerman is top notch.

Zimmerman AC is a very professional and honest company. They explained the AC service and parts which were being replaced to protect and service my American Standard home AC Unit. I have been using Zimmerman AC for the last 12 years because of their great customer service, value, professional workmanship and honesty. I am extremely greatful for their rapid response this week when my AC stopped cooling. Zimmerman is one of the best companies in San Antonio in my opinion. May everyone consider Zimmerman AC for their home AC service.

I switched to Zimmerman from another company, and was so, SO impressed! Luke, who did the initial visit for regular maintenance and fine-tuning of the system which hadn't been done since 2020 was extremely helpful in finding the causes for some of the things that had been frustrating us. He also took the time to SHOW me the problems, taking me up into the attic for myself so I could see what was going on and why he was recommending the solutions he did. Then, when we scheduled the repairs that we agreed were necessary, he was there again to work with and explain directly to the installation crew what needed to happen. In many situations like this, one person does the inspection and recommendations, and then a different crew of people come in to do the work, sometimes leaving some questions or unanswered issues. The direct handover worked great in this instance and we're so happy. They also left our attic so CLEAN after they finished! The previous installers left much of their trash up there, but the Zimmerman crew took all their waste out, leaving it looking much, MUCH better than when they started. They were also able to get us scheduled quickly for both the initial visit and the subsequent repairs, although we weren't in the hottest part of the summer. I can't recommend them enough!

We’ve used Zimmerman at our home for everything involving our air and heating after hearing great things from my in-laws. They have. Not disappointed at all! They’re always on time, very professional, and get straight to the repairs/work needed. They’re also always great with my kids, but that’s never a requirement! We’ll always use Zimmerman, if possible, and I cannot say enough good things about the service that we have received.

Was a long time customer of a different HVAC company who had become much more pricey and significantly less responsive/attentive. When my 20 yr old system stopped working recently...again, I decided to try another route. I was made aware of Zimmerman through friends of mine and decided to call. Phone rang twice and within minutes had an appointment scheduled for 2 days later. Trey arrived right on time and immediately proceeded to provide very informative and professional service. Within an hour my AC was fixed, I was a member of their club and was having estimates for a new system drawn up. I was given 3 options, all of which consisted of better equipment, a better system and considerably more affordable than quoted by others (including who I was a long standing member of for years). Trey was extremely professional, personable and patient. My new system will be installed soon and I couldn't be happier with the choice I made, with the service I was provided and with Zimmerman. Thanks Trey!!

After explaining the issue to him, Omar went up to the attic to look at our ducts. He was very knowledgeable and was able to explain what he found and some possible solutions. We asked him to seal a duct to force more air into a hot room. Procedure was successful and gave us the air flow we needed. Price was fair for service done. Future repair suggestions also sent to us by email.
