HVAC reviews in Chicago, Illinois

"Showed up late with a partial job, took deposit and then left unfinished."

The technicians showed impressive expertise in taking down our old AC unit. They were thorough, courteous, and handled everything with ease.

We hired Heating & Air Conditioning A C Chicago to replace our old heating and cooling system, which turned out great. The technicians were polite and worked quickly, finishing the job in one day. It's nice to have a comfortable home again thanks to their professionalism. Overall, it was a positive experience, and I appreciate the team's effort.

I'm extremely satisfied with their heating and air services. The technician arrived promptly, was courteous and efficient, and got the job done quickly. He explained everything clearly, so I understood what needed to be fixed. The price was fair, and the work was top-notch. They've consistently delivered reliable, quality service - that's why I highly recommend them.

I reached out for a quote on a minor task, but the representative only provided the service charge upfront. They asked about specifics later, which was too late since I'd already been quoted without being told what was included. The conversation ended abruptly when I mentioned it might exceed my needs - the rep seemed very unfriendly.

We had a heating issue start on a Sunday, but the team responded quickly, sending someone named Cory to fix it. He identified the problem and made the necessary repairs, which have worked smoothly ever since.

The service provider showed impressive expertise from the start. When I called, they answered promptly and demonstrated exceptional professionalism. They efficiently diagnosed and resolved the issue with my heating system, returning quickly to address another related problem - a minor electrical glitch - within just a few minutes.

Never been a regular customer, but I gave it a shot. Scheduled an appointment for 11am-2pm, took time off from work. Nobody showed up. Called at 1:50 to find out what happened. Told they'd get in touch with the technician and call me back, which didn't happen. Had to call again at 2:10 to be told the tech wouldn't make it. Asked if I could reschedule, but not confident they would've reached out without my follow-up call. Poor communication all around. Did manage to reschedule, will update this review once the work is done.

Had a great experience with this company, thanks to their exceptional service. The technician went above and beyond to resolve the issue and get our heating system working again promptly. He provided top-notch work at a fair cost, leaving me thoroughly satisfied.

Had a great experience with O'Donnell Heating & Air Conditioning! The technician called ahead to let me know when he'd arrive, which was quick. He's very skilled and thorough - explained exactly what he'd be doing during the service and what checks he was running. Impressed with his professionalism. Will definitely use them again and recommend without hesitation.

The technician arrived promptly, fixing a temporary issue on Monday morning, which turned out to be a faulty high limit switch. He also conducted some necessary maintenance on the furnace. As a single mom, I appreciate the competitive pricing and the company's transparency. The workers demonstrated honesty and dedication to their craft. Given my positive experience, I have no hesitation in recommending them and am grateful for the excellent service provided.

I switched from an old furnace to a newer, more efficient one through this company. A friend of mine suggested them, so I gave it a shot. Best decision ever - they're top-notch. The team explained everything clearly and checked in afterwards. Kudos for the great service.

I've had nothing but excellent experience with this company. They're incredibly professional, trustworthy, and incredibly skilled. The work they did was outstanding, clear communication, and done to schedule without any issues. I'll definitely be working with them again.

My furnace gave out cold, but the team at O'Donnell Heating came through in a flash. They were super affordable and got someone over ASAP. The tech, Eugene, nailed the problem right away and broke down the whole system for me to decide what was best - fixes or new one. He was top-notch and handled my pup like a pro too. Wish I didn't need 'em again but O'Donnell's now my go-to if I do have a breakdown.

We called them because our house had a dusty feel and we wanted to address it with a duct cleaning. The technicians arrived right on schedule, wore protective gear, and kept the area tidy while working. Afterward, the air felt cleaner and there was significantly less dust around. They even shared before-and-after pics of the cleaned ducts - the improvement was impressive.

I'm thoroughly impressed with this company's service. The tech arrived on time, was highly skilled, and took the time to explain what was wrong and why. They fixed the issue promptly without breaking the bank - I'd say they got it spot on. Their work is top-notch and I've been really happy with their reliability.

After hiring them, our system is running smoother. The technician did a meticulous job. Satisfied with the outcome.

Lovely workmanship.

Lovely abodes with warm hospitality from friendly residents.

A lovely living space with ample room to spare, set in a secure environment.

Great bang for buck, and they pick up ASAP when you call. Would definitely recommend to anyone looking for a reliable service.
