Best heating and air conditioning pros near Marengo, 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"

"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!!"

"I found my go to guys for HVAC. Jeremy was great. Fast, efficient and explained everything. Reasonable prices and watch for their specials. I trust them."

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

"Dave and Brian did a great job installing my new AC unit and cleaning my ducts yesterday. They were knowledgeable and efficient and they cleaned up before they left. The cost was very competitive....Dave actually gave me a break on the duct cleaning because we have so many vents! I HIGHLY recommend Perfect Temp for duct cleaning and AC installation."

"The tech was very polite and did great work.. I would recommend them to anyone needing HVAC work!"

"When our air-conditioning went out during a stretch of 90 plus degree weather, Jeff answered our call and came out the same day to fix our unit! He also followed up to ensure we were satisfied with his service. We could not be more pleased with his service!"

"After a few years of using other heating and cooling businesses I found Keith, he was always on time and ready to work. We had a few issues with our boiler system that was getting up in age and he said he could fix it but it may only last a couple years so we decided to just replace it. Keith gave us a great quote and was again prompt and thorough on installing the new boiler. We were so happy with him that when we needed AC work he was the first one we called, which we ended up getting a new AC unit as well as it was old and could have been serviced over and over again but now the new ones are more efficient and almost pay for themselves. So when our water heater went out there was only one person to call, Keith was here as usual, quick and clean and no issues. Now we call and have both serviced regularly by him and no more problems and can rely on his work to keep us comfortable in our home. Call Keith if you donâ t want to worry about your homeâ s systems you wonâ t regret it."

"In October of 2024 I had the most excellent good fortune to work with Greenlink Energy Solutions as part of an ComEd Home Energy Efficiency project that included replacement of the furnace/a.c. and water heater, as well as top to bottom weatherization of my house. Even before the project started both Olivia and Jarron took the time to answer any questions and address any concerns I had regarding the equipment being installed and the overall scope of the project. Day 1, first up was a couple of electrical guys, quickly followed by Jarron and his HVAC team, Ben & Ryan. All on time and ready to get to it. Professional, pleasant and remarkably tolerant of my nonstop questions about the systems, the guys went to work and, other than a quick lunch break, worked nonstop, not particularly concerned about the clock but more about getting to a reasonable stopping place for the day. By the time they were finished, everything was operational, square and plumb, all pipes, valves, duct work and conduit looking very slick, orderly and professional. (5 stars just on the sheet metal work alone). Next up was the weatherization team with Nick leading the charge. Again, on time and ready to go. These guys, Zarek, Steven and Danial, came in with a plan and went right two it, peeling off to address varying issues and again, once on the ground it was go time for these guys. Remarkably, all willing and ready to jump in to even the less desirable parts of the project (like who really wants to go into a hot attic and crawl around in the corners? But they did it and with no hesitation or whining). Over all there were several things that impressed me about the Greenlink teams. There is the obvious stuff, like the punctuality and, remarkably, the through cleanup at the end of each day, and also the obvious work ethic, mutual respect amongst the team members and easy and informative communication with me. I think what was the most reassuring though, you could see the obvious pride the Greenlink people take in their work and, just as importantly, the obvious pride they take in working as part of the Greenlink team. That says a lot. I would not hesitate to recommend Greenlink Energy Solutions to anyone. I suspect my neighbors are already tired of hearing about how good they are."
