“Absolutely an amazing company! Called on Tuesday because my furnace went out, they came out the next day. Zach was super nice and very helpful, ordered the part and came 24 hours later to fix it and help fix the coil that was falling into the furnace! He was very knowledgeable, and understanding. Thank you so much!“

“When I called with a problem froyo machine, they showed up next day and got it up and running again in less than 2 hours! Really friendly people who seemed to really take their time and try to diagnose exactly what was going on. Call Lauren or Ryan for all your HVAC and commercial refrigeration needs! ⭐️⭐️⭐️⭐️⭐️“

“Chris is a very hard worker. Found the issue I was having, and fixed it no problems. Ill be contacting blacks for all of my future needs.“

“Nate, as well as the service and office team have been really great to work with. We had a A/C repair that turned into a new install. While new is never good to hear the entire company worked at providing us the best deal with outstanding service.“

“Water heater started leaking on the weekend and Nate at Sure Service was the only service technician to call us back. He was professional and gave us a fair price despite our immediate need and circumstances. The other guys in town charged $125 for an emergency visit to tell us our old water heater was leaking (was obvious, we already knew) AND they weren’t sure if they could have a new water heater installed in the next week or so. We feel lucky to have found Sure Service. We’re sure glad we did.“

“Called North Iowa Heating with our furnace not working on a Saturday evening and John came right out to our rescue. Within a short time had our furnace back kicking heat out and also performed a little more maintenance needed. Very thorough and professional. Our furnace is 20 + years old and have asked for a replacement estimate from them which we feel will be fair and equal to the service we received this night. Highly recommended to others of his companies services“
