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.

    Fernando was excellent! He called me ahead of his arrival. He promptly proceeded to meticulously check the air conditioner and explained everything that was performed. We also had a great conversation!
    Response from the owner:Dear Michael, Thank you for the wonderful 5-star review! We’re so glad to hear that Jordan took great care of you. Calling ahead, being punctual, and taking the time to thoroughly check both your furnace and fireplace are all part of the service we strive to provide every visit. It’s also great to hear he explained everything clearly and made the experience enjoyable with some good conversation along the way.

    Bill came after hours. Great attitude. Knowledgeable. Diagnosed the problem with our 30 year old AC unit. Got us set up with a quick appointment with the sales folks to replace our old unit. Highly recommend. We have a service contract so no extra charge for the after hours service call.
    Response from the owner:Dear Lori, Thank you for being a Comfort Club member and for taking the time to leave us a review! We’re glad Bill was able to provide knowledgeable after-hours service and help guide you through options for your 30-year-old A/C system. One of the big advantages of Comfort Club is that no overtime charges apply for after-hours service calls, and we’re happy that benefit helped when you needed us most. We appreciate your recommendation and look forward to helping you stay comfortable with your new system!
