HVAC reviews in Chicago, Illinois

The technician was knowledgeable and upfront about the issue with my heating system, including a clear explanation of costs.

Great job on the service! The team arrived right on schedule and left the area spotless - exactly what I was expecting from a professional company. After receiving multiple quotes, it's clear you guys are the best value for your price. Your staff is courteous, patient, and genuinely care about getting the job done correctly.

I woke up to a frozen city and my furnace was out, causing panic. Luckily, I reached out to Andy on Sunday and he arrived within an hour to diagnose the issue. What impressed me most was that he didn't charge an emergency weekend fee, which is often a standard practice in such situations. The next morning, he was back at my place with space heaters and a new furnace installed, restoring heat by mid-afternoon. To top it off, he also replaced our old AC unit on the same visit. Throughout the process, Andy was transparent about costs and we agreed on everything before work began. His reliability, professionalism, and fairness made him stand out – I'd highly recommend him to anyone seeking a trustworthy service provider.

Needed urgent assistance at home, which they delivered quickly and efficiently, meeting my needs exactly when I required it.

I'm extremely satisfied with the value and quality of service I received from this company. From initial scheduling to completion, they were top-notch in their responsiveness. Andy came out to assess my system and provided a thorough diagnosis within two days. He explained his findings clearly and offered reasonable options for repair, taking into account my budget constraints. Unlike other companies that try to upsell, Andy recommended the most cost-effective solution. The price I was quoted upfront was exactly what I paid, with no hidden fees. I'm impressed by their reliability, trustworthiness, and professionalism. As a healthcare professional, I also appreciate the discounts they offer - it's a nice touch. If you need HVAC work or maintenance, I highly recommend this company; they did an outstanding job on my system!

Working with Andy was top-notch. I called him in the midst of a heatwave with an AC emergency, and he fit me in on the same day. The old condenser on my roof had been leaking freon for over 15 years - it was a mess. He presented me with two options: a temporary fix or a new unit. I liked that he gave me both choices. His quote was fair, so I went with the new one. Within days, he came out and swapped out the old unit for the new one quickly and efficiently. Andy kept me in the loop throughout the process, responding promptly to my questions and explaining things clearly. He's got a professional demeanor, which puts you at ease. I'm sticking with him for future maintenance work and any issues that pop up.

Stay far away from them! The glowing reviews didn't prepare me for the nightmare that ensued. The supposedly "quick" job has dragged on for over six months now. Not a single thing has lived up to the promises made in the contract. We're stuck in limbo, with no clear resolution in sight. They won't budge until payment is received, but I'm not willing to pay until everything works as intended. The result? No air conditioning, heating, or hot water. Trust me, you'll regret using them.

Heater stopped working, but the technician arrived promptly and got to work. He was efficient and did the job quickly. The house is now warm and comfortable again, and I'm grateful for that. It's clear they know their stuff – the repairs were done efficiently without breaking the bank.

I recently got a new AC system installed at my place, and it's been a huge success. From start to finish, AB Heating and Cooling moved quickly and did a top-notch job - everything was done on schedule and with attention to detail that's hard to find. What really impressed me was their straight-shooting approach and the solid guidance they provided along the way. They weren't pushy about upselling extra services; instead, they helped me find the best solution for my home and budget. The installation process was smooth, and I can already feel the difference in comfort levels. Overall, I'd highly recommend AB Heating and Cooling to anyone looking for hassle-free service from a company that puts customers first.

I hired Andy from Liberty Home Guard to fix my furnace and air conditioning issues on June 12, 2025. He initially told me both units needed replacement, but I wasn't ready for a new furnace yet so he left. A day or two later, I was able to secure payment, and Andy came back with a crew member on June 18 to install the furnace. However, it started raining and they had to stop work due to safety concerns. The next day, June 19, 2025, they installed the air conditioning unit on my condo building's roof. Everything seemed fine until June 30, when I called Andy because the AC wasn't working again. He said he'd come out that evening to take a look but never showed up.

The next morning, July 2, I texted him to confirm his visit, and he said he was on his way after stopping at Home Depot for supplies. When he arrived, he went on the roof to troubleshoot the AC and checked the furnace, trying various troubleshooting steps, including replacing fuses. He noticed a damaged wire on the roof and sent me a picture, suggesting it might have been caused by his crew member. The damage was repaired, and a new thermostat was installed from Amazon.

The AC worked fine until July 11, 2025, when I noticed very little cool air coming out. By July 16, 2025, the AC wasn't working again. To be honest, it's disappointing that Andy's company didn't take my issues seriously and resolve them properly.

I recently needed help with a heating issue, and Andy from AB heating came through quickly and efficiently. He arrived promptly at my place in Lincolnwood and sorted out the problem. I'm very satisfied with the service.

This team exceeded my expectations with their exceptional service. They came across as friendly, informed, and willing to address all my concerns without feeling hurried. It's clear they put customers first and take pride in what they do. If you're searching for a trustworthy local heating and air provider, I'd highly recommend them.

I recently encountered a heating problem, but couldn't identify the cause. Given my previous poor experience with another company, I was hesitant to reach out for help. Thankfully, this service delivered exceptional professionalism from start to finish. Unlike my last attempt, I felt genuinely supported and didn't have to wait in the cold while the weather was bad. The technician arrived despite the freezing temperatures and resolved the issue promptly. I'm truly grateful for their excellent service - I'd highly recommend them to anyone I know.

We had a crisis in our multi-unit building during freezing temps and it seemed like everything was on hold. AB HVAC sprang into action, showing up fast and fixing the problem ASAP. They also made repairs and replacements as needed - top-notch work. For emergency situations like ours, they're the only game in town for the Chicagoland area.
