Tyler Reiser, was here yesterday and serviced our fireplace. He was very efficient and did a great job!

m.s. R.

Service was done as part of regular HVAC service agreement. Bill and his trainee Raydn provided service to both AC and heater because my schedule made an AC servicing impossible. Then Bill knowledgeably recommended an addition to help make my home's indoor environment less allergen filled, plus caught a failing part. They had both parts with them so were able to complete the work immediately. Hurrah for Kalins' immediate full-service attitude.

Robin B.

Kyle is an amazing technician who completed all requested tasks in an extremely professional manner. He completed everything to standard and thoroughly cleaned afterwards. Honestly, the best experience I’ve ever had with a technician. Thank you very much Kyle! HVAC Rockstar!

James K.

We have had a problem, cold air, with our propane fireplace others have failed to fix. Kalins sent Jeremy out to evaluate our problem. He discovered the orginal instalation ( not by Kalins) of the wind shield was upside down and correct that. He also made a couple of other corrections or suggestions for our use. No charge! We will follow up to see if that corrected the problem. If not Jeremy has additional steps we can take. Jeremy is great; knowledgeable, detailed, effective and very nice to deal with. I would highly recommend Kalins.

Linda L.

Luke was very professional! He told me that he was coming and when he was here told me what he would be doing! I like Luke! Very nice

We took advantage of Kalins $99.00 furnace maintenance offer this year and they sent Bill out to do the job. We have a Heil furnace that was installed in 2013 by an independent contractor. Bill knew what needed to be checked and found two capacitors that were at risk of failure. He replaced the parts and cleaned up the furnace. We will purchase one of Kalins yearly maintenance plans to keep the furnace and AC running smoothly.
