HVAC reviews in Oak Lawn, Illinois

I had a major problem with my radiant floor leaks. Multiple companies came out, but none could identify the cause. GMI Heating & Cooling arrived within 2 hours and quickly pinpointed the issue - it was fixed in under 5 minutes. I'm extremely satisfied with their service and will definitely be using them again for future projects.

I ditched King in Frankfort after they abruptly stopped showing up when I needed them most - no heat at 30 degrees. My dad steered me towards GMI instead. The comms were stellar - regular updates, confirmations, and heads-ups about their arrival time really made a difference. Esther was top-notch, and Jose Zavala's professionalism, honesty, knowledge, and efficiency won me over. I'm done with King and will stick with GMI from now on.

This company is the only one I'd consider for home heating services. When I had issues with my furnace, Esther provided excellent support - her patience and friendliness are a big plus, especially since English isn't my first language. The whole process was hassle-free and Esther remained professional throughout. I'm impressed with their customer service, which is why I'll be recommending them to others.

Diego did an outstanding job - he accurately diagnosed the issue and provided a solution that worked. His professionalism left me satisfied, and I appreciate his help in making my home comfortable once more.

We couldn't have asked for a smoother experience. They handled our bypass humidifier replacement with ease, offering competitive pricing that outshines other companies we've researched. Since the previous homeowner never serviced it, we began experiencing random headaches and allergies/sneezing issues. It wasn't until we discovered the unit was leaking that we found mold had accumulated inside. GMI was the only option that provided fair prices. Our technician, Jose, was exceptional - courteous, thorough, and efficient. He walked us through every step of the process, taking care to avoid any damage or mess. What impressed us most is GMI's genuine commitment to treating their customers like family. They truly put people first, making a lasting impression on our experience.

We've had heating and cooling problems since moving in four years ago. Fix it HVAC finally addressed our issues, showing they're knowledgeable and genuinely invested in solving customer problems. Their commitment to satisfaction is refreshing - a rare find these days. We're extremely pleased with their service and will definitely be using them again in the future.
