Zach professional. He was friendly; he acted as though he didn’t want to be anywhere else but cleaning and maintaining my HVAC unit. Keep up the good work!

Update: November 28, 2023 Omar arrived on time and proceeded to check out the gas heater/ furnace unit. All is good. Omar checked out our outside A/C unit this past summer - in the middle of the Texas heat wave in late August. He recommended that we probably need to change or replace our 16 year old unit. We got a quote from his company in early September but at that time, the company was in the middle of being sold. Our quote got sidelined. We will revisit the HVAC system in the next couple of months. Winter in Texas doesn’t last that long. It will be warm again in 12 weeks! Another update: May 2023 Our variable blower motor went out so Zinsmeyer came out to replace it. Eric, who was the tech sent to diagnose and replace the blower motor was wonderful and efficiently checked out the entire system. He had the house cooling down on a warm and humid day pretty quickly. Also, he checked the outside unit to make sure everything was working as they should. When he was satisfied, he asked if there were any questions and of course, none because he covered his bases well. Mission accomplished! One thing though. You might want to ask your techs to wear protective cover on their shoes when working inside the house. I had to clean a lot of dirt where the tech walked and worked. He was in and out of the house several times so there was a lot of gritty dirt. Other than that small issue, everything went great. Update: Jose Villareal was the technician that showed up today. I was very impressed because he took his time to do the work that he was suppose to do. He cleaned both filters, and cleaned the outside unit to the point where he got wet! He talked to me about the progress of the work he was doing. He took a longer time than any of the other techs but now I know why. I'd rather have somebody as thorough as Jose than somebody who shows up and gets things done in 25 minutes. Thank you, Jose! Keep up the good work! Technician arrived as scheduled. The business office apparently tried to call beforehand but they were using a disconnected phone number. Luckily, the tech showed up anyway. I updated the phone number so they can reach me next time. As far as the maintenance service goes, he serviced the outside unit first and then came inside the house. The tech was quick and efficient. This company shares the same last name as the one that installed the unit 12 years ago. That brother that installed the unit reportedly sold his company to his other brother hence the same last name. No matter, I’m satisfied with the service. I signed a membership agreement with them and according to the tech, we can call them anytime and they will be here to resolve any problem related to the HVAC unit.

Leroy Zinsmeyer.. From the receptionist to Martha any time I need an inspection or a repair you are prompt and responsive! My last inspection/repair was complex but Jacob was through and extremely knowledgeable. This Technician is hard working and a real asset! I have been using Zinsmeyer for + 30 years and trust their judgment and reasonable costs. Thanks Bill Gunst

Well let's face it, no one ever wants to call for an AC repair, but if you have to.... I highly recommend you call Zinsmeyer Air Conditioning & Heating. When my AC went out, I called Zinsmeyer AC&H and Leroy had one on his technicians out within an hour. After diagnosing the problem, he was able to get the unit running to get some cool air going, but the unit needed to be replaced. The next morning he called with a quote and provided me with several options, I made a decision and his team went into action. By the end of the day I had a new Air conditioner installed.Outstanding customer service combined with reasonable price points!Zinsmeyer Air Conditioning & Heating is the only company I'll use for my future AC needs.

Jacob came out to inspect our heating unit and air ducts. He was very courteous and explained everything well. He even took pictures to give me a better understanding of the condition of the ducts in the attic. I would recommend this company for anyone needing HVAC maintenance.

Called Zinsmeyer ACH, a tech was sent out and did a fabulous job. Not only was the technician professional, he explained what was going on with my unit, was clear with the work that needed to be done and what the cost would be. It was an incredibly pleasant experience dealing with Zinsmeyer ACH. I would recommend them without reservation for your ACH needs.

It was the best AC company I could ask for, they came to my need when I so dearly needed it. My AC stopped working and when I called, they came to help as soon as they could. Our system went down and it was very cold that weekend but thankfully they came very fast and helped and adjusted to all my needs and I highly recommend choosing this company for all you AC and heating needs.

The ac in our house wasn’t cooling, called Zinsmeyer and they got there really quick and had the parts they needed on hand and fixed the problem fast, and it didn’t cost an arm & a leg, they had very good pricing. Would recommend them to friends/family ?
