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.

I had good HVAC service from Bill.

Response from the owner:Dear Roxy,
Thank you for the 5-star review and for sharing your experience with us. We’re glad to hear Mikah was able to resolve the leak and that you were happy with the overall repair.

We do appreciate you pointing out the concern with the dripping water. That’s not the level of care we expect in our customers’ homes, and your feedback is helpful so we can continue to coach our team on the importance of protecting the space while completing a repair.

Thank you again for choosing Kalins Indoor Comfort—we truly appreciate your business and the opportunity to serve you!

Had Kalins install new heat pump in 2025. Today received follow up complementary service call to ensure ready for summer. Mikah was punctual and professional. Good company to work with. Recommend.

Jennifer C.

Mother board crashed on my newer unit I purchased in 2024. HVAC technician Fernando was very helpful in explaining the issue and was here for close to 5 hours staying until the job was complete. Very friendly & professional!

Response from the owner:Dear Jennifer,
Thank you for the 5-star review! We know how frustrating it can be to have an unexpected issue like a motherboard failure—especially on a newer system—so we’re glad Fernando was able to get everything taken care of for you.

Staying on-site for several hours to see the repair through and taking the time to clearly explain the situation is exactly the level of service we aim to provide. We’ll be sure to pass along your kind words to Fernando!

Thank you for trusting Kalins Indoor Comfort with your HVAC system repair—we’re always here whenever you need us.

Amy

Bill was very friendly, knowledgeable, and professional. We have had such a great experience with Kalins today and over the past few years. A huge thanks to Kalins for installing our amazing new system in late 2023. Bill has been here for routine annual services since and he always does a great job! Thank you!!

Response from the owner:Dear William,
Thanks for the 5-star review—we really appreciate you taking the time to share your experience!

We know how frustrating a “no cool” situation can be, especially on a newer system, and we’re glad our team was able to take care of it quickly under warranty. That’s exactly the kind of peace of mind you should expect.

Kevin was great. Was with him whole time, explained everything answered questions, etc. Appreciated showing me things and options and opinions.

Response from the owner:Dear Brandy,
We’re glad Kevin took the time to walk you through everything and keep you informed during your no-cool service. Clear communication and giving homeowners options is exactly what we aim for, so it’s great to hear that stood out.

We appreciate you choosing Kalins Indoor Comfort and trusting us with your home!
