"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"I had Zach to my house when the heat went out on the coldest day of the year. He was great to deal with, a hard worker, very knowledgeable. He takes time to explain things and takes great pride in his work, like a true professional. I also manage an 18,000 square foot building in Wicker Park, I called him when we had a boiler problem, and again he handled it with great professionalism. I’ve referred him to others and we’re all happy customers."

"Dan was incredibly helpful every step of the way. He broke our estimate down for us, separating the cost to just replace the boiler and to add a radiator to one of our rooms. He also had a plan to be able to do the projects separately, if we wanted. We ended up doing everything together. It was very quick, the techs were super polite and knowledgeable. Would HIGHLY recommend."
