David Dalton

I highly recommend Calumet Cooling. I recently had them over for routine maintenance. Calumet Cooling resolved significant airflow issues that previous firms were not able to. Calumet Cooling also went above and beyond by explaining what they were doing, and what they recommended. Calumet Cooling will be my “go-to” for future work as well as my furnace maintenance this Fall!

Client Reviews


Jacquelyn Smith

Alex was amazing! He dropped in my new bakery to introduce himself and drop off his card but he (and I) was in luck because my commercial fridge wasn’t cooling properly. He came back that same afternoon with the necessary equipment to service the refrigerator and had it cooling properly once again. He also did a quick walk-through of other equipment to see if anything else needs service. He was friendly, helpful and affordable. He called back 2 days later to check in on the equipment he repaired to make sure it was still functioning properly. I will be using him again for any service needs (including my water heater soon). Highly recommend this small-business owner.

Daniel Berger

THANK YOU, THANK YOU for your AMAZING service! We are very grateful for your flexibility, honesty, and A+ quality! My family and I appreciate the quality of work, the professionalism and friendliness Alex exhibited. He worked very hard and was very polite to me, my wife and daughter. Alex answered any questions we had and even offered advice on how to get the maximum efficiency from our systems. He is our goto for all our HVAC needs. The best in St Charles, MO, highly recommend you call Alex today!

Great and knowledgeable service! They have worked on both my a/c and furnace, spotting problems before they developed. My system is running really well. I particularly appreciate how thorough Calumet has been each time I have used them.

My wife and I own a business and had a broken rooftop unit, our technician Alex showed up same day and got it fixed that same day for FAR less than the numbers I had in my head! Thank you Calumet!
