Callahan's is the business to call if you want exceptional service for HVAC. Collin, Matt, and Drew were the perfect gentlemen I had the pleasure to work with. They had great attitude about their work and the company they work for. They seemed to genuinely care about me and the work they did for me in replacing my heating/cooling systems. They were professional, articulate when explaining the equipment and service, and were just darn good men. I would and will recommend this company hands down. Another plus is that they are veteran oriented. I'm value and support our veterans as they so greatly deserve. I couldn't be more pleased. Thank you so much.

The heater went out in my mom’s house while I was working out of state. I was referred to Callahan Heating & Cooling so I called first thing in the morning and they were able to get us an appointment the same day. The technician, Isaac Robinson, showed up earlier than promised and thoroughly checked everything, quickly diagnosed the problem, and ensured it was fixed properly. He was very knowledgeable and enthusiastic about his trade and explained things in a way that was easy to understand. He was very professional, trustworthy, courteous, and his prompt solution to our heating problem was greatly appreciated! Thanks to the great job done by this young man my family is warm again and Callahan Heating & Cooling has earned our future business! Thank you! Chad Jackson 10/26/24

They were able to send somebody the same night that I called. Even though I didn't call until after 6pm. Ryan was great. Super polite, quick, held good conversation, & didn't leave until the problem was fixed. It's been 2 days & everything is still working properly. No more issues. Thank you so much. I really appreciate you all.
