Miranda truly went above and beyond for our family. Her compassion, professionalism, and in-depth knowledge were evident from the very beginning. She took the time to explain every detail, answered all our questions with patience, and made sure we felt completely confident in our decisions. It's rare to find someone so dedicated and genuinely caring. Because of her, we are 100% sold on Callahan. We couldn’t be happier with our new gas furnace and AC unit, and we highly recommend Callahan to anyone looking for outstanding service and expertise.

We had a great experience with Callahan Heating & Cooling from start to finish. Josie at the office was so friendly and helpful. They were able to come out the same day I called to give me an estimate on replacing our ancient AC unit and furnace. Colin and Brett did a thorough inspection to get us a straightforward estimate. Drew M. & Levi S. came to install our new units. They did a phenomenal job and kept me updated on the status of everything. When the furnace was having issues with a switch not working, Drew made sure he got a replacement part ASAP. It was nice knowing he wanted to make sure the job was done - and done correctly - before leaving. Really appreciate how friendly, efficient, and professional everyone was! Callahan Heating & Cooling will be our go-to from now on. Update 5/28/25: our brand new AC unit had a sensor issue. Colin W and Ryan S came out and went above and beyond to take care of the issue. Very happy with how quickly they were able to get to us. Their customer service is top notch!

You have customers and recommendations from us for life!!! Collin, Drew, Andrew, and Levi you are the drean team!! I wish we would have called you guys years ago! Collin thank you for taking the time to listen to our current issues & what we wanted, and explaining how each unit would preform for us. Your knowledge made making the commitment to move forward that much reassuring. Drew, Andrew, and Levi thank you so much for making it seem as though our household chaos was no interruption to you - two large dogs, a cat, a ferrel toddler, and working remotely. We had even started the morning off with a thunderstorm. You didnt let any of this take away from the beautiful install or you customer service. You guys are good poeple and that put everyone in house at ease!! Drew special thanks for taking on our Frankenstein unit and getting everything back up to code and looking beautifully. It is never fun having to go back in and clear up someone elses work but your knowledge and dedication to your work has us beaming. As for our new unit- it was cool in the afternoon when the beating sun normally makes sitting in the living room unbearable. We slept for 12 hours last night uninterrupted and comfortable, it was glorious! The difference in the cool air and the pressure that is blowing from our vents now is soemthing I have dreamed of! I have no comments for inprovement or suggestions as you guys have just blown our expectations out of the water. Again and 1,000 times over THANK YOU SO MUCH!! You have made what we thought was to be a dreadful experience an extremely easy one and wish we would have called you sooner!

Today was our first service visit with Callahan Heating & Air out of Ozark, MO, and I’m extremely impressed. We just signed up for an annual service agreement covering two homes in Nixa, and Miranda came out for the initial spring maintenance. From the moment she arrived—right on time—she set the tone for a truly outstanding experience. Miranda was thorough, kind, and thoughtful. She took the time to explain everything she was doing, even showing pictures along the way so I could clearly understand the condition of the units and what steps she was taking. Her attention to detail was especially evident when cleaning the outdoor unit—she didn’t rush, and it’s clear the system will be running more efficiently as a result. Scheduling was simple and flexible, and the whole process felt professional yet personal. You can tell the team takes real pride in their work, and it shows in both the service quality and customer care. Based on this first visit, I have full confidence in Callahan and wouldn’t hesitate to recommend them to friends or neighbors. Thanks to Miranda and the whole Callahan team for a great start—I’m looking forward to working with you throughout the year!

We had Drew Marks come out on Friday on an urgent repair on our inside unit. He was very knowledgeable of what had happened and had found the unit that was improperly installed by a different company was missing a couple of fittings to prevent leakage past the drain. He was quick and used his time after repair to explain the situation and give more recommendations to keep the unit working properly. No intensive lengthy sales pitch after repair like most companies will push. Would recommend Callahans services to anyone in need!
