    The housing of mother board inside furnace unit.

    On January 20th 2025 around 2 am the furnace in my apartment made a grinding noise, and things stopped. No hot air what so ever. The outside temperature -26 centigrade, 0r 26 degrees below zero. I manages till 9.45 am, calling the management company, & the strange process to get help. The management company is skeptical of the gravity of situation. Finally they contacted ER AIR. They (team of two) arrived in the afternoon, at scheduled arrival time, good thing, looked at the furnace, did the diagnostics, & went to buy the replacement part. Returned, & went to replace the internal circuit board, which was malfunctioning. And the furnace started up. literally life saving event, in temperatures this cold. The technicians were very nice, knowledgeable & capable to do the job, with no nonsense. I am grateful to George which did most of the intricate maneuvering of the replacement part and installation. Thanks a million for your hard work & professionalism, in those difficult hours.

    30 year old unit finally gave up the Ghost.

    When your furnace goes out on the day before NYE and its freezing out, who ya gonna call?? THESE GUYS! They came out in two hours, sourced a brand new Weil McClane unit and after several hours, had it up and running. FAST, professional service; they respect your property And mask up appropriately. Would Definitely recommend.

    Before the cleaning. That's a lot of loads of laundry worth of lint, despite being careful to clean the lint filter after every load!

    Hero Air is great as far as I can tell. I mean it seems like nothing comes cheap but they at least…read moreseem fair. I will copy the review I wrote about ABC, which lead me to hiring Hero Air in the first place to give you the full picture: Update: ABC did show up at 8pm the following night and proceeded to quote me $1,363 to replace some components and $475 to deep clean the condenser coil. I was paying for their VIP service and that is the quote I got. I said no way since I trust them zero. Got Hero Air, who get amazing reviews on Yelp to come out and were there within 2 hours. Turns out I needed a new thermostat, which all in for diagnosing, running out to get the thermostat, and installing for $407. He also recommended a deep cleaning and charged me $150, so for $557 instead of $1,833 which wouldn't have even fixed the problem I am up and running 4 hours after requesting an appointment. So when I said above they hope idiots will let them get away with charging triple, I was not exaggerating. ABC deserves to go out of business. It seems like with their AI reservation system and "fluid" scheduling they probably go bought out by private equity and it seems like they are running themselves into the ground. DO NOT USE THEM FOR ANYTHING!

I greatly appreciated this communication and that I always felt in the loop! I especially appreciated getting an alert a half hour before the cleaners arrived so that I was ready. From the moment the cleaners arrived, they were kind, professional, and efficient. They helped me get everything ready for the cleaning, get the cats put in a secluded space, and got me setup outside for a work call. They were very respectful and willing to work around my work situation. The requested service of air duct cleaning was completed within a timely manner and very thoroughly. A few hours after the cleaning, I can already tell the difference in the air quality! Wonderful job, Mr. Duct! Best of all, Mr. Duct is very reasonably priced for such high quality service. Truly a great value! After working with Mr. Duct twice over the course of several years, and experiencing high quality service at a great value, Mr. Duct has won our confidence! We will definitely be using them again next time we need air duct cleaning!

    0/5 Stars -- Two Cancellations, Zero Accountability…read more I want to warn others before booking with Air Flows Chicago. What should have been a simple service appointment turned into weeks of frustration and a complete failure of professionalism. We requested a quote online, paid a deposit, and scheduled an appointment for a Sunday afternoon (2-5 pm). We never received a confirmation email, but assumed the booking went through. When we couldn't reach anyone by phone to confirm, we let it go. On Sunday morning at 10 am -- hours before our appointment -- we got a call telling us they don't have technicians working on Sundays. Nobody could explain how we were able to book a Sunday appointment through their own online system, or what we were supposed to do next. I called Monday and spoke with a manager who admitted this was a known issue with their scheduling system -- one they were "working to fix." I was offered a discount and rescheduled for the following Friday, 8 am-12 pm. Okay, frustrating, but I gave them another chance. Thursday evening, less than 24 hours before that appointment, we received a voicemail saying our Friday appointment was also being cancelled because of "another service." No explanation, no apology, no alternative offered. I called back furious. I made clear I wanted someone to show up for the appointment we had. The person I spoke to went to check with a manager -- who couldn't even be bothered to call me directly. When they called back, the answer was simply: reschedule for next week. No compensation. No acknowledgment of the repeated failures. Nothing. The only thing Air Flows Chicago did quickly and without issue was refund my deposit when I demanded it. One additional note: their online booking system never made clear which location -- Air Flows Chicago or Air Flows Chicago Belmont -- was handling our appointment. We still don't know. That lack of transparency is itself a problem, and it's why I'm posting this on both listings. Two cancellations. A known broken booking system they hadn't fixed. A manager who wouldn't get on the phone. And zero effort to make it right. Save yourself the headache and book someone else.

    Being a home owner, there are many projects that need to be taken care of yet I can't execute them…read morealone on many of them. After a few weeks of cold and snowy days in late January and February, I felt the furnace and the ducts might need a major TLC. I contacted "Chicagoland Air Duct" via Yelp messaging where one can request a quote. Their office responded to me in a fairly timely manner and detailed the pricing and work that will performed. That alone was a determining factor and I decided to do business with them. Other companies either charged a bit high in my opinion or didn't delineate much of anything at all in their communications. Scheduling was easy. I did it all through Yelp messaging. We were able to do in the same day, but I opted for a Sunday service because my partner and I would both be home. E-mail and text confirmations were sent right after booking with an approximate time frame that the technician(s) will arrive. The lead technician for my project was also assigned with their first and last names. Everything appeared to be very legit and professional! Jerry, the lead technician and Anthony, the assistant, arrived in the beginning of the time frame. Jerry called me and announced his estimated time of arrival. I thought it was very nice because both my partner and I were having our morning naps (lol)! The house has two (2) furnaces. However, I just needed the one that serviced basement and first floor to be cleaned for today's purposes. They were efficient and knew exactly what they were doing. Jerry suggested a furnace cleaning upon inspection for an additional charge ($99). I knew our furnace was quite dirty since no major maintenance was done in the past. My partner and I agreed with the add-on and then Jerry went right into work. By the way, they were also good listeners. We have two (2) indoor cats and I had an unpleasant experience with one of them went outside when someone was performing a home improvement project in the past. We spoke to them about the cats being inside one of the rooms that had a vent. They were ok with touching the basement vents after the first floor ones were completed. They accept cash, checks, and debit/credit cards. Jerry also recommended some follow-up maintenance on our furnace. I'm planning on using "Chicagoland Air Duct" again for the top floor vent cleaning and furnace inspection. I had a positive experience with the company. Their prices were fair; workers were professional; communications were prompt and clear.

    Further update- we just learned that we have carbon monoxide circulating from our furnace. The…read moretechnician who ran positive tests for carbon monoxide in multiple ducts throughout the house pointed to a faulty heat exchanger and/or poor installation. He noted that the heat exchanger was set to combusting gas. As I wrote in my last updated review, we became aware of issues with the installation last season when I noticed water pooling on top of our furnace. Another HVAC technician diagnosed the pipes venting the furnace were not sealed. This allowed condensation to escape at multiple joints in the pipe that seeped down and pooled on top of the furnace. When the technician removed the front of the furnace, we found a layer of rust and build up on the bottom interior of the furnace. He said that we are lucky that this didn't come in contact with a nearby circuit panel, but that we should take care of it ASAP. Chicagoland Air Duct reiterated that it was outside their warranty, and further added that they no longer do furnace installation. After speaking with a Goodman Rep about a possibly faulty heat exchanger I was told that the part definitely is covered by the warranty, but that the labor is not. Another HVAC company quoted around $2000 for that labor. I am about to contact Chicagoland Air Duct and ask them to please do the right thing and address this problem. Wish me luck.
