Best heating and air conditioning pros near Antioch, IL

"This was our second call to All Temp for service. Mike was our technician and he is very knowledgeable and professional. He gave some good advice on cooling our house, what to look for in the HVAC system in a new house (we are looking), and didn't try to up-sell me on things we didn't need. He was quick with his assessment and work. We'll be calling them again if we have HVAC issues."

"The technician did a very good job cleaning the hvac ducts."

"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!!"

"Buyer Be Aware: If the Person doing the work tells You that you Cannot Use Your Credit Card (if After 5:00 PM), Do NOT Listen! Pay the Following Day during Business Hrs.!! Also, when my New HVAC System was being installed 2 Days After Duct Cleaning, the HVAC Contractors called Me into the Basement and Showed Me the Inside of the Ductwork just after Opening it: Tons of Debris Remained Inside! Hopefully, if You Hire, Your Experience Will Be Better...Good Luck!"

"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."

"Fixed an issue that literally dozens of other HVAC contractors could not fix"

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

"Salesman was knowledgeable, friendly, and low-pressure. Replacing HVAC units is never cheap, but their pricing was reasonable. Scheduling was easy. Furnace replaced as proposed, with no issues. Will be replacing AC in the spring."

"Professional service, extremely skilled at diagnosis issue. Will continue to do business with Long Shun HVAC"

"One hour heating of lake villa went above and beyond. Furnace was making load noise when it kicked on. Completely obvious he knew what he was doing. They repaired it, checked for other signs of issues, and cleaned up the furnace. The cleaning was a job on its own since it has not been serviced or cleaned in about 8 years. Customer service was outstanding and understanding. It s a new home to us and in the past I always used to call the company with the sticker on furnace from previous owners. I will be using one hour heating from now on for all my Hvac needs. Thank you"
