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!

Lori B.

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.

Mikah did a great job! Checked furnace, mini split, and AC. He even took care of a bunny that passed away in our AC unit. (How did it get in the AC unit?) Anyway, great job! Would highly recommend Kalins to anyone!

Response from the owner:Dear Angela, Thank you for the fantastic 5-star review! We're so glad to hear Mikah provided such thorough service on your furnace, mini-split, and A/C.
