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.

Jori J.

We are so excited to start enjoying our new electric fireplace! We replaced a troublesome gas fireplace that caused us a lot of anxiety over the last year. We decided with the help of Evan to go with the Kozy Heat Osseo 34 and we are so happy that we did! Evan went above and beyond walking us through what installation would look like and eliminated any concern we had! We also couldn't have had a better installation team of Brodee and Chris! They were efficient and very detail oriented! Our fireplace looks brand new again and we just wanted to say thank you!

Response from the owner:Dear Jori,
Thank you so much for the wonderful review! We’re thrilled to hear how happy you are with your new electric fireplace and that the Kozy Heat Osseo 34 was the perfect replacement for your previous unit. It’s great to know Evan helped guide you through the process and made you feel confident about the installation.

We’ll also be sure to pass along your kind words to Brodee and Chris—they take a lot of pride in their work, and it’s great to hear the installation went smoothly and that your fireplace looks brand new again.

Thank you for trusting Kalins Indoor Comfort with your home comfort. We hope you enjoy many cozy evenings with your new fireplace! 🔥
