What Our Customers Say

"Mario is one of the best people u can get! Honest and very dedicated. He did some work for me a couple of years ago, and now is doing work for my elderly mother. He is patient and has been very kind. I would recommend Mario for any of ur heating or air conditioning problems that may come up. He is great at maintaining ur equipment too!"

Worked with Mario to diagnose a problem with my condo's heating system - he was fair and shared a heap of knowledge on possible solutions to the problem. Smooth communication of problem and possible solution. He also provided a long term strategy should other problems arise. I'll recommend him.

Great service from the technician. He came out to my home, assessed the problem, and EXPLAINED what was wrong. He didn't try to get over on me because of my lack of knowledge. Instead, he tried to educate me on the issue and even showed me how I could troubleshoot the problem and later fix it on my own.

I haven't written a Yelp review in a while, but Mario came through for me in a major way and I wanted to give him a shout out. Our landlord/slumlord was being non-responsive about fixing our broken heat. Mario was able to squeeze us in that day and fixed it. He then sent a helpful email describing his recommendation and detailed invoice for me to send to my landlord. He would have done more to fix it, but was restrained by the fact that we weren't the owners. Mario struck the perfect balance of fixing our furnace so we had heat, but not doing the bigger changes that would have been inappropriate because we weren't the owners of the unit. He was great at communicating his timing and even followed up with me after to check if the heat was still working. Great service.

Thank you Mario for being so efficient and informative. We recently bought our home and I know it's time to start preparing for the Chicago cold/winter. I knew my radiators needed to be bled/purged. Mario offered this service along with a radiator tune up at a very reasonable rate. I sent a quote request this past Saturday I responded on Tuesday and Mario was able to fit us into his schedule today (Wednesday morning). Mario was thorough and gave us honest advice. I definitely recommend Mario. Mario, you may see many referrals as I work in the insurance industry and have numerous requests from clients on who they should call for different home services!

Mario is excellent. He has come out to my place twice now for a heating tune up and recently I had an AC issue. Within minutes he was able to identify the issue and was upfront about the charges. He seems very knowledgeable and seems to really enjoy his work. I will absolutely use Mario again, should I need any more AC/Heating help.

Mario came out quickly after my 30+ year old AC went out (with a pregnant wife in the house). Provided a very honest quote, and replaced my AC and furnace. He was dealing with his own family issues, and even stayed until midnight one night to make sure my family had AC. He was professional, honest, and did a fantastic job.

Chicago Heating & Air Conditioning delivered excellent heating repair service. The technician arrived on time, repaired our furnace efficiently, and ensured it was running safely. He was professional and friendly. The pricing was reasonable, and the service was great.

Outstanding HVAC service, knowledgeable technicians, prompt repairs, affordable pricing, very satisfied.
