One AC company told me both of my systems in this 2 year old house had to be replaced to the tune of $60 thousand. They evaluated and said it didn't need to be replaced. Shortly after moving in, the ceiling flooded due to the AC pan. They responded immediately even though I wasn't a client. They also figured out the hospital grade filtration system that had been uninstalled by the prior owners (It had been installed backwards)

They came in super early, understanding that our business relies on customers coming in and being comfortable during this Texas summer, and started work on installing our Mitsubishi heat/air system. Not only is it cooling wonderfully, but the paint job they did makes the necessary wiring and tubing seamlessly blend in with our walls. They were also the only of FOUR heating and air conditioning companies to perform a heat load evaluation. I'm very satisfied with the work and their employees were amiable, consistent, and answered all of our questions!

My neighbor and I both purchased system from Zimmerman due to recommendations from previous…read morecustomers. The install of the system went flawlessly it's just the after care that is nonexistent . Its been three years for both me and my neighbor and they have never called or returned to do the maintenance that was promise or anything at all. It seems like they are like every other company that just wants to take your money and run. I would not suggest you wasting your money on such a poormy managed/owned company. It sad to see such a good company get ruined by poor management .

If 5+ stars were available we would give Zimmermann the highest rating. We have used Zimmerman's…read moreservices for several years. They are the best at customer service, complete knowledge of hvac machines and their functionality. We have used other companies during our more than 50 years of home ownership. Zimmermann is the best by far! Over time they have done repairs for us, we have their maintenance contract which we recommend and they replaced our entire hvac system. Every call whether maintenance, service, repair or replacement was handled with white glove level care. The technicians know hvac systems well, people in the office are friendly and efficient and we won't go anywhere else. Thank you Zimmermann! Dan & Rose Mary S. Schertz

Dear Blueline AC Team, I wanted to take a moment to express…read moremy sincere gratitude for the outstanding service you provided during a challenging time. After experiencing frustration with another company over the holiday weekend, your team restored not only my AC unit but also my faith in honest, dependable businesses. What impressed me most was your straightforward approach, quick response, and genuine commitment to making things right. It's refreshing to work with people who truly stand behind their word and treat customers with integrity. Your small business embodies the kind of service that makes a real difference. Thank you for going above and beyond Amanda, JC, and Daniel. I'm grateful to have found such reliable professionals, and I look forward to recommending Blueline AC to others.

I wanted an efficient, quiet, reliable, longer lasting system. I had several companies provide recommendations and estimates. I was most impressed with TemperaturePro San Antonio owner Courtney Meier and chose the DAIKIN HVAC. Her install team was very professional and extremely careful of our home. Installation of our two systems was completed in two days. TemperaturePro performs our semi-annual system checks. Although I usually request the same technician I had during the previous visit, that scheduling hasn't always been possible. But it doesn't really matter as I've come to realize every TemperaturePro technician is very well trained, professional, careful, and friendly. They always keep us well informed about what they are doing and answer all questions. TemperaturePro's technicians are tops!! I had an issue with the drain lines that came with our home. They occasionally clogged causing the A/C unit to shut down. Courtney made a recommendation which I had them install and drainage has never been a problem again. I also needed one of the condensers moved about a foot to accommodate a new larger gas meter. TemperaturePro responded the very next morning and took care of it in a manner that looks like it was always where it is now. Exactly what I wanted. I'm extremely happy with TemperaturePro and the DAIKIN HVAC and they have my highest recommendation! Rick Trent
