Luke always does a great job explaining what the maintenance covers and what he will be doing. I appreciate his ability to speak on my level. He’s kind, courteous, professional and we enjoy having him service our system. Great job!

Aaron not only did a good job, but he did a great job. He was pleasant, explained in layman’s terms what the problem was, and repaired it immediately. He took the time to make sure everything was functioning properly before he left. Thank you, Kalins, for taking good care of our HVAC needs!
Mary Kay S.
Kalins is great! I would highly recommend signing up for their annual service checks. They are very thorough and provide great peace of mind knowing that things are working as they should be. I recently had an appointment with Tyler. He is awesome! Prompt, very knowledgeable, professional, and helpful. Thank you!
Lisa K.
It’s never fun having to replace your whole system, but Kalins was beyond exceptional every step of the way. Quality products, quality service, and even better people have made a life long customer in me. I will recommend them to everyone I know, every chance I get. It’s not hard to see why they have been around as long as they have.

    Everyone I’ve spoken with at Kalin’s is so nice and so knowledgeable, and our tech, Radyn was no different during our inspection today. He went out of his way to answer all our questions and showed up early, got the work done quickly, and helped us schedule the next step of the process. I also really appreciate Kalin’s commitment to the community. They recently helped our church navigate a challenging situation. Very generous!

    Bill was great to work with as he tried to troubleshoot the problem with my heat pump. He spent time trying to figure out a complex issue and gave me multiple estimates on how to address the problem. I would recommend him and this company if you’re looking for someone that cares to spend the time to help you figure out the problem with your HVAC system.
