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.

Everyone at Kalins that we worked with was great! Adam and Jeremy for inspection, Fernando for maintenance, Josh salesman, Kenneth, Kellen and Anthony for removal and installation of new units. Courtesy, respect, professionalism describe them best. Couldn’t ask for better service from these guys. Thank you all for such a great experience.

Anthony and Ken were great. Very polite, pleasant and helpful.

Response from the owner:Dear Kim,
Thank you for the 5 Star Rating and Review for our Service Technician Bill! We’re glad Bill was able to step in quickly and take great care of your family. When a furnace stops working, comfort and safety come first — and providing space heaters while we order parts is just one way we try to ease the stress. We appreciate the opportunity to come back first thing in the morning to walk through your options and get everything resolved. Thank you for trusting Kalins Indoor Comfort — we’re here for you every step of the way!
