"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!!"

"Kyle came to inspect my condo's HVAC. He was punctual, friendly and professional. I'm a new homeowner and he patiently answered all my questions about this stuff! I couldn't get access to the ac on my roof, so he didn't get to look at that but he spent a lot of time making sure my furnace was cleaned and in good order and looked at the air vents. He found a small gas leak on the furnace and sealed it up for me, thankfully. I will definitely contact them again for anything HVAC related!"

"Coldest Polar Vortex in history -44F, our 10+ year old furnace said no more. Travis, from Lifeline was here in 3 hours. We upgraded to a dual stage, 96%ECM, 100,000 BTU, HVAC. Travis also was able to get us a $450 ComEd rebate. Before leaving, he loaned us new, highly efficient space heaters, while they picked up our new system. Bob and John completed installation within 3 hours, no breaks. Its worth noting they also installed our A/C in 2017 with the same elitist standards as our new HVAC. I would highly recommend to family and friends. Lifeline has become like family, -perfectionist till the end. My hat is off to you, Lifeline."

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

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

"AWE promptly responded to my work request and kept me informed about my appointment status. Peter came to perform the work. He was very thorough and even discovered that the HVAC contractor on our new home installed 2 furnaces: a current year model as well as a prior year model that was more prone to breakdowns. Provided great information and would definitely hire again. Thanks!"

"I talked to Nick who was good enough to send a technician out the very same day that I scheduled the service. The technician, Dan, was very prompt, thorough and friendly. He cleaned and sanitized 10+ vents, HVAC system, returns, supply lines, main line, and the dryer vent which was on the roof. A lot of Groupon deals that I looked around for have up-charges for the requirements that I had, particularly since I live in a 3rd floor walk-up in the city. With Lowe's the price that was quoted was the price that I got! I will definitely use their services again!"
