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!

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.

    Kyle not only did an excellent job with the maintenance of the heater but he became best buddies with our toddler during his visit. Kyle was kind, efficient, and our son had an absolute blast “helping” him, which Kyle was patient enough to humor and encourage him. Highly recommend Kalins and specifically Kyle as the technician!

    Josh stopped by my house on 2/4/25 to answer questions I had about Kalins Freebruary Promotion for Systems. He did a thorough evaluation of the systems I presently have (taking measurements, serial number, looking at duct work (showed me how the damper works), making sure I had proper vents, etc.) We then sat at the kitchen table where he educated me on the features of the different systems they offered. I appreciated Josh's honesty and helping me to choose a system that best fits my needs and my budget. Josh's communication skills are top notch and he is an excellent educator! Keep up the good work!

    Jeff Miller completed an excellent service maintenance call and was very cordial . After completing the servicing , he installed a Micro-Air Easy Start Flex on my system. This device will make it easier to power my HVAC system with a small power generator during an electric power outage by reducing the amps needed to power up the compressor used by the system. I would recommend the use of their maintenance services.

    Caleb Emerson was the Technician from Kalin's that came to our home yesterday's, 01.17.25.
    He came on time, very polite called me Ma'am 🤗.
    He even called my contact number 30 minutes before our appointment, told me he's on his way. I really appreciate that. We've been with Kalin's from the time my Husband Bill & I bought our home over 30 years ago.

    When Caleb was done inspecting/maintaining our Central Furnace, he showed me what he's diagnostics results were. Explained it so clearly, that there's no charge as we've been signed up with their Comfort Club's over 5-6 years or longer.

    Caleb asked me if I have any questions at all, of course - there's none. He's soo professional.

    Thank you so much Caleb!
    You're a great asset to Kalin's!

    Trevor listened to my description of our heat pump’s sounds and did a THOROUGH review of it physically and also went over the computer ‘trouble log’ connected to the thermostat ( can you call those minicomputers we use to set our temps/times with ‘thermostats’ anymore? ). After finding no issues with the heat pump, he tried to figure out the compression issue messages that occurred repeatedly- narrowed our problem down 4 dogs that shed and living on country roads and farmland…the filter I changed 4-6 weeks ago was thick with all that air can carry . Now looking to experiment with weekly checks on the filter to see how fast it really ‘gunks’ up. THANK YOU for your diligence and super kindness , putting up with all the voca, four legged ‘helpers’!

    Our furnace decided that it wanted to not work right, so we called Kalins to take a look at it. The guys who came to look at it were very nice. Then Josh came over to give me pricing for a new furnace and explained everything. The day came, and Will, Pat, and Brady installed the new furnace. They were all very nice, polite, and easy to talk to. My dogs also loved all the pets they got. 😊 I highly recommend them!

    Amazing!!! Mason did amazing job! He explained everything to us to the best of his ability for us to understand as first time homeowners. He didn’t bull**** us an tell us or up charge us in anyway! He explained the price asked us if we wanted to proceed and fixed it fast!!! He didn’t just fix it an then tell us later. Great communication to the customers!!! He recommended the right people to come in and look at our system since it’s 20 plus years old and explained that it’s best to replace the whole thing at once since the pricing of everything going up on parts, you’d paid more in parts probably then in just getting a whole new system. They’ve worked on a few of our trailers an have not once tried to tell us or upcharge at all!!! Highly recommended Kalin’s!!! Amazing job!!! Great communication!!!

    Tyler Beiser with Kalins came out to my house for a service call on a outdoor temperature sensor, while here he exceeded more than just replacing the sensor. He did a complete diagnostics of the furnace and heat pump , worked on making sure my humidifier was in working order also. Tyler is very knowledgeable in his field, and takes time to explain everything in detail about the working order of the system. Most of all he very genuine and caring to make sure that your family is ready for the upcoming winter. He is truly an asset to Kalins and Vermillion and surrounding area.
    Thank you for a job well done and peace of mind.

    Kyle not only did an excellent job with the maintenance of the heater but he became best buddies with our toddler during his visit. Kyle was kind, efficient, and our son had an absolute blast “helping” him, which Kyle was patient enough to humor and encourage him. Highly recommend Kalins and specifically Kyle as the technician!

    Josh stopped by my house on 2/4/25 to answer questions I had about Kalins Freebruary Promotion for Systems. He did a thorough evaluation of the systems I presently have (taking measurements, serial number, looking at duct work (showed me how the damper works), making sure I had proper vents, etc.) We then sat at the kitchen table where he educated me on the features of the different systems they offered. I appreciated Josh's honesty and helping me to choose a system that best fits my needs and my budget. Josh's communication skills are top notch and he is an excellent educator! Keep up the good work!

    Jeff Miller completed an excellent service maintenance call and was very cordial . After completing the servicing , he installed a Micro-Air Easy Start Flex on my system. This device will make it easier to power my HVAC system with a small power generator during an electric power outage by reducing the amps needed to power up the compressor used by the system. I would recommend the use of their maintenance services.

    Caleb Emerson was the Technician from Kalin's that came to our home yesterday's, 01.17.25.
    He came on time, very polite called me Ma'am 🤗.
    He even called my contact number 30 minutes before our appointment, told me he's on his way. I really appreciate that. We've been with Kalin's from the time my Husband Bill & I bought our home over 30 years ago.

    When Caleb was done inspecting/maintaining our Central Furnace, he showed me what he's diagnostics results were. Explained it so clearly, that there's no charge as we've been signed up with their Comfort Club's over 5-6 years or longer.

    Caleb asked me if I have any questions at all, of course - there's none. He's soo professional.

    Thank you so much Caleb!
    You're a great asset to Kalin's!

    Trevor listened to my description of our heat pump’s sounds and did a THOROUGH review of it physically and also went over the computer ‘trouble log’ connected to the thermostat ( can you call those minicomputers we use to set our temps/times with ‘thermostats’ anymore? ). After finding no issues with the heat pump, he tried to figure out the compression issue messages that occurred repeatedly- narrowed our problem down 4 dogs that shed and living on country roads and farmland…the filter I changed 4-6 weeks ago was thick with all that air can carry . Now looking to experiment with weekly checks on the filter to see how fast it really ‘gunks’ up. THANK YOU for your diligence and super kindness , putting up with all the voca, four legged ‘helpers’!

    Our furnace decided that it wanted to not work right, so we called Kalins to take a look at it. The guys who came to look at it were very nice. Then Josh came over to give me pricing for a new furnace and explained everything. The day came, and Will, Pat, and Brady installed the new furnace. They were all very nice, polite, and easy to talk to. My dogs also loved all the pets they got. 😊 I highly recommend them!

    Amazing!!! Mason did amazing job! He explained everything to us to the best of his ability for us to understand as first time homeowners. He didn’t bull**** us an tell us or up charge us in anyway! He explained the price asked us if we wanted to proceed and fixed it fast!!! He didn’t just fix it an then tell us later. Great communication to the customers!!! He recommended the right people to come in and look at our system since it’s 20 plus years old and explained that it’s best to replace the whole thing at once since the pricing of everything going up on parts, you’d paid more in parts probably then in just getting a whole new system. They’ve worked on a few of our trailers an have not once tried to tell us or upcharge at all!!! Highly recommended Kalin’s!!! Amazing job!!! Great communication!!!

    Tyler Beiser with Kalins came out to my house for a service call on a outdoor temperature sensor, while here he exceeded more than just replacing the sensor. He did a complete diagnostics of the furnace and heat pump , worked on making sure my humidifier was in working order also. Tyler is very knowledgeable in his field, and takes time to explain everything in detail about the working order of the system. Most of all he very genuine and caring to make sure that your family is ready for the upcoming winter. He is truly an asset to Kalins and Vermillion and surrounding area.
    Thank you for a job well done and peace of mind.
