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.

Tom L.

Needed to replace the old worn out wall air conditioner in our lake house so called Kalins. We love our new Lennox mini-split. Next couple of weeks will be in the 90’s and I am not worried. The house is cooled and efficient, plus we can start it before we leave for the lake with our phone! Shout out to Trevin and Neil for the great install!

Andy H.

Knowledgeable staff and super courteous.

Barbara Lewis P.

Bill was great! He was very professional, friendly, and fixed my AC quickly. He explained everything clearly and made the whole process easy. Great service!

Ethan T.

Will & Dylan absolutely crushed the water heater install. They worked quickly and everything looked great when they were done.

Jacqueline K.

We had a wonderful recent experience with Kalins Indoor Comfort! From the beginning of our work with them, as Jordan Smith came to investigate our cooling issue, and Josh Alcorn coordinated the purchase of a new A/C and furnace, I knew Kalins was a good choice to work with. These gentlemen answered all my questions, and fully explained the process for this home repair. The scheduling and financing processes were smooth, and we were able to get things going quickly, even with a holiday week approaching. On installation day, Will and Dylan did a great job with moving our water heater to make room for our new unit, and got us all set up on needed tech for monitoring. Anthony Palma was helpful in explaining our new thermostat, and Chris did quality work getting our HVAC system going! Throughout the whole process, the Kalins team was pleasant, professional, efficient, and helpful. We look forward to working with them in the future!

Brady and Max did an excellent job installing our new system. They explained the complicated looking thermostat very well. We were very happy with the service. They even went above and beyond and brought the old water heater up out of the basement for us. That is something we appreciate very much. I highly recommend Kaylins for all your HVAC needs. Thank you so much guys!!!
