Reviews of local pros in Cincinnati, Ohio

Technician was pleasant and very knowledgeable. I have never had a heat pump system before so I was trying to educate myself on the system. He showed me the different parts of the system and answered all my questions, which was much appreciated.

I've been a property manager in the Greater Cincinnati area for over thirty years and have tried a number of different HVAC companies. Zimmer has been hands down the BEST! Getting proper installation is SO crucial and their installers are excellent. Communication from staff and techs is prompt and courteous. As a property manager, they make my job a lot easier. Thank you Zimmer Heating & Cooling!

Great experience again! Dan provided our service in early December this year and he performed a complete inspection, helped me with understanding our new thermostat, and educated me on the our entire system. He is extremely knowledgeable and a very nice and personable professional. Thanks Dan for everything and I hope to see you again and again for service! Thanks!

Zimmer called ahead the day before and the tech called when he was 30 minutes away. Awesome customer service. The tech (Carter) was super polite and presented himself very professionally.

I had a great experience! This was my first time working with Zimmer. My service provider showed up on time, presented himself professionally, and worked efficiently. Thank you!

Zimmer is fantastic. They’re always quick to respond, and everyone I’ve dealt with has been friendly, professional, and super helpful

I had an excellent experience with Zimmer. From the initial consultation to the final installation of our new systems, they were professional, prompt, and knowledgeable. Dan took the time to explain our options and made sure everything was tailored to our home’s needs. No high pressure tactics here. The installation was smooth, and the difference in comfort was immediately noticeable. It’s great to support a business that takes pride in quality work and outstanding customer service. Highly recommend.

I just had the annual service performed on my furnace and the technician, Jovante, did a great job. Zimmer has always been professional and courteous and I would highly recommend them over the other local guys.

I had several episodes of my heat shutting down. Another company came twice and got it going again, but didn’t find the problem. The Zimmer people did a much better diagnostic and found the problem which was a faulty gas valve. I paid for the replacement which was quite expensive, but they did not charge me for a return visit.

Had water leaking out a radiator bleed valve during Super Bowl. Zimmer got out to us quick and stabilized the situation. The following morning they were out to do final repair. They delivered when we had to have them! Thx Christopher!

Our experience with Zimmer was a 10 out of 10. They were very responsive and attentive. Knowing how hot it was I felt they delivered pretty quickly. I didn’t feel alone In the process whatsoever. Everything was communicated to me or my husband. We received great service With our new AC unit! And would highly recommend. We also received a technician to ensure everything was properly installed, and everything is working correctly. They were very friendly. RJ and Demetri were our install technicians and Dan was our main contact.

Very good initial consultation with Rob regarding some issues with my home’s boiler system. We discussed contributing factors and options to resolve issues. It will require further investigation. I’m pleased with the service so far.

Zimmer was prompt and easy to work with. The technician was friendly, professional, and explained everything clearly. I’d definitely use them again.

Darien was very professional and installed a new thermostat. He arrived on the very day I made a call. Great service! New thermostat good so far!

Zimmer HVAC Tech Christopher was meticulous and professional in diagnosing and cleaning out our mitsi mini split that got badly ruined by elements and animals. Repaired it quickly and also explained what he was doing all along. Great experience! Zimmer HVAC is a keeper.

Christopher arrived on time, completed the work quickly, explained to me the purpose of each task and left at completion of the service. He was very helpful and knowledgeable of his trade. I am very confident of his skills and feel the job was done well.

I had a very good experience with Zimmer. The communication with scheduling an appointment was good. I got a call before the service person shown up. His name was Logan, he arrived on time, told & shown me what was wrong and fixed the issue with my leaking furnace. I'll use Zimmer for my future HVAC needs!

Service guys and the sales man were great to work with professional and knowledgeable on products ... So when they left I had some heat not out completely .. Zac came back today and got the oil up and running very professional young man, very respectful and very professional about telling us what to expect ... Zac is a pleasure to meet.. Zac is a compliment to your company . He will get my business any day tks Zac Zimmer

My husband and I cannot talk highly enough about the customer service and service from the technicians we received. We had an old oil boiler that was well over 60 years old and had no idea where to start with replacing it. Dan and his team came out and thoroughly went over every aspect of what needed to/would be done and made us feel secure about the decision and process. Within HOURS dan had the parts ordered and within 3 days an entire new oil boiler system was installed! The crew we had at our house those 3 days were courteous, respectful, knowledgeable, and thorough in their work. They made a stressful and overwhelming decision process for us easy and unburden-some—- we highly recommend Zimmer and their team!

I chose Zimmer HVAC to install and maintain my steam boiler. Another preventative maintenance visit was no disappointment with Chris! Thank you for a comprehensive visit with explanations and the courtesy to Even greet my dog! Thank you!

Zimmer did an excellent job for me! Responded quickly to my inquiry, assessed the job & priced it, scheduled installation, were very professional while installing, did a great job installing, and finally, post job follow to make sure it was working correctly & we knew how to use it. Performed well above expectations. Thx! Patrick
