What our clients say?

“Among the best hvac contractors in town. I've had plenty of experiences with other companies as I am an owner of an office but so far AAA Comfort has really been the only hvac contractor offering the "complete package" - a great combination of hard, honest work and affordable price. Last time they came for a faulty boiler repair and managed to find and fix the problem really easily.”

“I am a property manager for a townhouse complex in Joliet. I manage 44 units in 11 buildings. About 4 years ago we had another service company taking care of our heating and air when we realized we were being taken advantage of. My boss instructed me to look around to find someone new quickly because I had an elderly tenant who's furnace had just gone out and it was cold outside. I began calling around and kept getting the runaround about wanting someone to come out the same day or the price was so high even I couldn't believe it.  That was until I called Elmer and Lisa at AAA. They gave me an amazing price and said they could have someone out within the hour and they did exactly that.  It was then I decided to ask them to be our full time go to company for ALL our heating and cooling issues.  I can call and have called Lisa in the middle of the night on weekends and even Holidays when one of our systems goes down and they get right out to take care of it. I read a review that said all of the positive comments were from friends and family and I just wanted to say. They didn't start out as friends or family they started out as our heating and cooling company but over the years they have become great friends and I would even say family.  They care about their customers! They have never tried to sell me something we don't need and they have never over charged us for anything.  We would highly recommend this company to anyone!”

“AAA is an outstanding company, I HIGHLY recommend them. My water heater decided to start leaking and it was pretty much pouring water. I called at 3 pm and Elmer was here by 8:30 am the next morning (my leak wasn't an emergency so I picked the date and time). They told me what time they would be here and they were on time. The office said they would call when they were on their way and they did! Elmer is very personable and knowledgeable and he didn't try to charge me for something I didn't need. I will definitely be having him back in a few months to service my boiler. Outstanding customer service!!”
