HVAC reviews in Chicago, Illinois

I highly recommend John for HVAC services. He's a top-notch technician who gets the job done right every time. Extremely reliable, courteous, and thorough in his work on my heating system. If you're looking for quality service, look no further than John.

They responded promptly to scheduling requests and arrived on schedule. The technician quickly identified the problems with both units and explained the necessary fixes clearly. Prices were fair, neither too high nor low, considering the scope of work done. Overall, excellent service.

I've relied on Union Heating And Air Conditioning for two tough situations, and both times they came through. I got an appointment quickly and Mark fixed the issue efficiently - he's top-notch. I'm a fan of their reliability and would definitely choose them again and sing their praises to others.

Came out for a scope on the NEST system installation. Found issues with the existing HVAC unit, including damage to freshly painted walls. Contacted them multiple times, but each call goes straight to a call center. They claim someone will follow up and address my concerns, but 24 hours have passed with no resolution. Notified they don't have a direct line to a manager, which doesn't instill confidence in getting priority support.

Samuel did a great job during our appointment, providing a detailed explanation of the work being done. He came across as genuinely friendly and professional, taking his time to ensure everything was understood. I'm excited to get my new AC installed before the hot weather sets in - he's definitely worth recommending.

My heating system went out for five days when temperatures plummeted. Despite multiple calls every few hours, no one ever arrived to fix the issue. It took three attempts for someone to show up, but they couldn't resolve the problem and promised another technician would be sent - which never happened. I was initially assured by other contractors that this company had my situation under control, so I didn't pursue help elsewhere.

I got an estimate from Union Heating And Air Conditioning, which sent Samuel over. He was courteous and showed respect for my home by removing his shoes before entering. During the assessment, he explained how a new furnace would help reduce my energy costs. His professionalism made a good impression, and I'm confident in recommending them to others.

We recently hired Union Heating And Air Conditioning to replace our furnace, taking a cautious month to ensure everything was done correctly before sharing my experience. The team displayed professionalism throughout the installation process, with Mark clearly explaining each step of the diagnosis and repair. His expertise put me at ease, but I'll be keeping an eye on how long this new system lasts us in the years ahead.

I chose Union Heating And Air Conditioning initially because they're a veteran-owned business, which stood out to me. No diagnostic or visit fees were charged, and one-visit appointments eliminated the need for two separate meetings. The owner handled the work personally - Samuel. He showed up on time, was pleasant, efficient, and got the job done. Our problem was fixed by the scheduled start time of our appointment.

We had a broken heating system, but thanks to a friend's referral, we got connected with Union Heating And Air Conditioning. Their technician showed up promptly, being both professional and friendly. The issue was quickly identified and resolved. The cost was fair. Overall, I'm very satisfied with the service, which is why I'd wholeheartedly recommend them to anyone in need of HVAC assistance.

The installation of the furnace I recently purchased was botched by Union Heating's technicians, who seemed completely clueless when it came to getting the size right for my specific building.

After my old 20-year-old furnace gave out, I hired this company to install a new one. But after they finished, I still had problems with airflow, and I was told that I needed to redo my ventilation system. That turned out to be just a Band-Aid solution - the real problem was that the furnace I got was way too big for my place.

I went back to three other companies and asked them to take a look at it. Every single one of them agreed with me: the furnace wasn't properly sized, and that's why it wasn't working right. But when I brought this up with Union Heating again, they just wouldn't listen.

One of those other companies did manage to tweak the furnace so it would run without any issues - but even they said that what Union Heating had done was only temporary, and that if you don't install a new furnace with the right size for my unit, it's going to burn out in no time. But when I told Union Heating about this, they claimed that every other company was wrong.

I sent one of those reports to their HVAC supervisor, but he just sort of acknowledged everything without directly contradicting it. He told me to contact the manufacturer, which I did - and what did I get? A canned response that wasn't very helpful at all. But at least the manufacturer confirmed what those other companies had said: a load calculation should be done to figure out the right size for my furnace.

When I told Union's supervisor this, he promised to contact the manufacturer again and get back to me. Months have passed, but I still haven't heard from him or anyone else at Union Heating.

Today, I had another problem with the furnace - it turned out that a different company was able to fix it pretty easily. But when they looked at it, they told me that the furnace is still too big for my place and that it won't last much longer than 5 years.

So now four companies are all saying that Union Heating got it wrong, and I'm having to save up because I know I'll need a new furnace in just five years. And to make matters worse, their payment system was so sloppy that they accidentally charged me the wrong card information - and after that, my bank blocked them from processing my payments. So now I've had to cancel my card and reorder a new one.

I hired AirNest Heating and Cooling Solutions for an HVAC fix and was pleasantly surprised. The tech showed up right on schedule, was friendly, and did a top-notch job of getting things sorted out. They even gave me some solid advice on keeping my system in shape. My issue is now resolved and I'm thoroughly satisfied with the result.

If you're looking for a slow and frustrating experience, they're your best bet.

I had a critical AC issue and reached out to them for emergency help. They responded lightning-fast, dispatching someone on the same day. The repairman got the job done swiftly and with impeccable professionalism. Their rapid and reliable service is truly appreciated.

Dealing with HVAC issues is a hassle, but AirNest turned it into a breeze. Their pros are top-notch - genuinely professional, skilled, and courteous. They pinpointed the issue fast and fixed it without any hiccups. Their work is spot-on, no frills or fuss.

Excellent experience. Highly recommended.

Scorching service that left me breathless.

Excellent experience with this home services business. Highly professional team, great service. Would definitely recommend to friends and family.

Had a great experience with this company. Received quick response and the AC unit was fixed promptly, leaving me very satisfied.

The technician did an excellent repair on the heating system.

I'm glad my friend hooked me up with this guy, and I'm thrilled with the experience. The work was done on time and done right - no fuss, no muss. I had a tricky issue that wasn't immediately apparent, but he figured it out without trying to make a sale. Top-notch service!
