Get matched with top heating and air conditioning pros in Antioch, IL

"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"

"HVAC machine outside wasn’t working. Ricardo ? was so good at explaining & suggesting his expert ideas. There was a mouse & nest inside the machine & wires were severed. He removed the critter & nest & repaired the wires. All is working again. What a great guy he is!!"

"Work was done quickly and the HVAC technician was very helpful."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."

"Everyone from the sales person to installers were great. I love our new HVAC system!"

"Unfortunately, our homes and the systems that provide heat, electric, plumbing, etc. do not last forever and must from time to time get repaired and replaced. I have owned a home for over thirty four years. While over the years I have used many HVAC companies, I cannot think of a more professional, friendly, informative and quality heating and air conditioning company than One Hour Heating and Air Conditioning."
