    Csaba has come to our rescue more times than I can count. Whether it's your furnace, your…read morethermostat, or your air conditioner, he strides in with a smile on his face, quickly assesses the problem, whispers a magic incantation, and suddenly, your HVAC is as good as new. In cases where you could have solved the problem, he'll show you exactly how to fix the issue in the future. He's even diagnosed some issues by looking at photos we've texted him. His prices are FAR lower than you'll be bracing for. And while other folks will hint that you'll need to replace equipment, Csaba knows that most faulty equipment can be tweaked back to life with a new part or a minor adjustment. This man is an artist and a wizard and an absolute godsend. He'll be our HVAC guy 'til we die.

    Csaba (pronounced Cha-ba) is great! I wish I'd found him sooner. He came out today for routine…read moremaintenance, but also to check on a few minor issues I was having with my furnace. He knew it well because it turns out he used to live in my building on Chicago's northside! His communication is great -- he answered immediately when I called. And we scheduled the appointment for just a few days later. He also called me the morning of the appointment to let me know he'd be "12 minutes late!" :O SO many workers are always late...I really appreciate that especially since it wasn't even majorly late. He wore a mask and removed his boots without me asking. He was friendly and personable. He listened to my issues and then showed me the simple fixes that I can do myself in the future. He basically said "let me show you this so you don't have to call me to come out in the middle of the night..." This is a guy that knows customer service and isn't at all about trying to get more money out of you. He knows the importance of word of mouth and quality work. He is great and VERY fairly priced. I highly recommend him without hesitation.

    STI Heating & Air Conditioning saved me so much money! I had another HVAC company looked at my…read morecentral air unit because it was blowing lukewarm air. The other company told me I needed a new compressor for $1699 and they took only cash. After a repairman ran off with $453 of my aunt's cash, I decided I did not feel comfortable giving the HVAC repairman $2000 (with labor) in cash. So, I told him I would seek a second opinion. I called STI Heating & Cooling who were booked for the week so I made an appointment for the following week. Ted arrived on time and was very professional. He took a look at my unit (which is 42 years old) and told me I needed a Hard Start Capacitor for $173. He also checked the amount of Freon (R22) told me I might need a little. He installed the capacitor and added a little Freon and my unit start blowing extremely cold air. Ted's work was great! He told me his father had an old unit like mines and he keeps him father's unit working. I told Ted the other repairman thought I needed a new compressor and Ted suggested maybe the other repairman was not familiar with older units like mine. I am SO glad I called STI Heating & Cooling! I told Ted they are now my go-to company for ALL my HVAC activities. I would highly recommend this company - they proved to be a huge money saver for me.

    The service was amazing! Customer service was very helpful and the technician provided excellent…read moreservice. And they were reasonably priced! I would definitely recommend STI Heating & Air Conditioning to anyone looking for repair and/or great service. Will definitely contact them again for future repairs and checks. :)
