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.

Bradley came out today to clean and inspect our ac system. He was very professional and friendly, and he did an outstanding job. Martha also was great getting us the report that we needed for the sale of our home very promptly. Zinnsmeyer AC and Heating is a great company and we will continue to use them for our HVAC 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 ?
