HVAC reviews in Chicago, Illinois

Zac fixed our heating issue quickly, showing up within 30 minutes on a weekend evening. He cleaned the burners and flame sensor, explaining the process to me too. The repair took less than an hour, getting us back up and running again. Zac was pleasant and courteous throughout - thanks for the good service!

I recently completed a large 3-flat HVAC installation project with multiple systems that required careful attention to detail. After meeting with several companies, I found Mike Clark at All-Temp to be the most knowledgeable and transparent about their services. He listened attentively to my concerns and took the time to address each question without any pressure or sales talk.

Our initial bid process was a back-and-forth negotiation, but Mike remained patient and collaborative throughout. What impressed me most was that he didn't try to push for a specific solution; instead, he worked with me to find a mutually beneficial agreement.

When installation time arrived, Mike visited the property twice more to ensure everything went smoothly. He explained each step of the process to technicians Sal and Ben, who were both professional and courteous. What struck me was that All-Temp didn't rush the install and used multiple installers in a single day like some other companies. This attention to detail paid off, as we've had three out of four systems installed so far.

I'm now just finishing up the final installation, which should wrap up next week. I've been thoroughly satisfied with the quality of work, equipment, and overall service from All-Temp. They've proven to be a reliable partner, and I look forward to continuing our relationship in the future.

We left our house on Sunday afternoon and came back around 11:30pm to find it freezing inside, with a temperature of just 59 degrees. The next morning, I called Art, the field supervisor, at 6:30am, hoping someone would come soon. They promised between 8:30am and 1:00pm, and by 10:00am, technician Brandon arrived.

Brandon was friendly, courteous, and professional from the start. He noticed we had a space heater nearby and offered some useful advice on how to use it more efficiently. As he got to work, he methodically diagnosed the issue with our furnace - within 30 minutes, he'd pinpointed the problem as the gas valve. However, he couldn't find one in stock, so he called his office for assistance.

Within 45 minutes, Brandon returned with a replacement valve and fixed the problem. By noon, our furnace was up and running again. I watched him work and appreciated how he explained the issue in simple terms. He was very thorough and knowledgeable.

I'm really grateful for the service we received from ALL TEMP. Highly recommend their team. Thanks again.

All Temp has been and will remain my top choice for HVAC services. Their customer service is exceptional - from installation to emergency repairs, they consistently deliver. Today's experience was a perfect illustration: when my furnace stopped working, I called and got a repairman out within 3 hours; Edwin assessed the issue and made it right. They're always upfront and provide the best service around.

Zac from All Temp saved the day when my furnace stopped working during a cold snap. It turned out to be overheating due to a clogged filter. The rattling noise from another repair company's blower was also fixed by Zac. He serviced our furnace on the same day and we got our heat back up and running. I later found out that Zac had been servicing my home since 2013, even before I bought it. His reliable service has earned him a spot in our regular maintenance routine.

Knowledgeable technicians delivered quality workmanship. They clearly explained the problems and proposed solutions, which seemed reasonable. The cost was spot on for the job done. I'm pleased with the outcome and will definitely suggest this company to others who need heating/cooling fixes.

We switched to All Temp after years with another HVAC company that was starting to fall short. We're thrilled with the switch - they've been top-notch from day one. Their service is prompt, professional, and efficient, and they respond immediately to any issues.

A huge thank you to our last technician, Marvin, who went above and beyond when our furnace broke on the coldest day of the year. He put in extra effort to get us back up and running, even returning on a Friday night to install a tricky part so we wouldn't be stuck in the cold all weekend. This level of dedication is rare.

All Temp has earned our loyalty for good. They've set a high standard, and we'd definitely recommend them to others.

We've had an old home with ancient radiators that just wouldn't heat up. The guys from All Temp sent someone out and it turned out to be a lifesaver - this guy really knew his way around a boiler. Unlike other companies we've tried, they actually delivered results. He cleaned both furnaces, swapped the valve, and fixed some other bits. It was a bit of a puzzle, but he figured it out and got all the radiators working again, which had been on the fritz for ages. Now our system is up to date and running smoothly - thanks to this team's expertise.

Marvin provided excellent service, being very forthcoming about the inspection process and explaining his findings in detail. His prompt communication made a significant difference - I'm glad I reached out right away to catch those crucial cracks in the heat exchanger. Fortunately, it was discovered before any issues escalated.

Our old steam boiler gave out two weeks before Thanksgiving, putting our six-unit building in a precarious position just as a polar vortex was looming. We were initially led to believe that replacing it would be a lost cause for the holidays. That's when All Temp stepped in and proved to be the only viable option. Marlen Jr and his team worked efficiently and effectively, keeping us informed every step of the way. Their professionalism and attention to detail were truly impressive. The end result was nothing short of magic - we're now warm and cozy for the holidays. I wholeheartedly recommend All Temp to anyone in need of reliable heating services.

Edwin's annual maintenance visit was top-notch. He thoroughly inspected our furnace, boiler, and humidifier, providing clear explanations of the findings. Extremely helpful and knowledgeable, he offered actionable tips for improvement. The level of professionalism and expertise exceeded our expectations - a truly exceptional service experience that we'd highly recommend to others.

Randy was polite, knowledgeable, and upfront about costs. He provided clear guidance on necessary repairs and suggested waiting on less expensive fixes. His transparency earned my trust. Throughout our interaction, Randy demonstrated professionalism, making the entire process stress-free.

Zach nailed it - our heating system's back up and running smoothly. He arrived right on schedule, exuded a high level of professionalism, and broke down complex issues into straightforward explanations. The fix was swift and efficient, with no unnecessary hassle. Zach's expertise shines through; he genuinely knows his stuff. We're grateful for the prompt service and would wholeheartedly endorse him to anyone seeking reliable, speedy assistance.

Ashe's annual furnace check-up was a standout experience. The technician's politeness and attention to detail were evident from the start - he put on shoe covers as soon as he entered my home. I appreciated his focus on cleanliness throughout the process. What really impressed me, though, was the thorough explanation of what he checked and serviced, including the status of each component. His expertise, combined with kindness and trustworthiness, made for a truly exceptional service. It's clear that Ashe prioritized customer satisfaction, and his efforts paid off in a very pleasant experience.

I was impressed by the company's efficiency, courtesy, and affordability. Owner Andrew was courteous and ensured a reasonable price for the new igniter. Technician Randy was friendly and efficient. Overall, I'm delighted with the service and highly recommend it to others.

I recently had a technician from AllTemp come for the annual cleaning and maintenance of my appliances. The service was efficient, with Randy arriving promptly and completing the job thoroughly. He took the time to answer all my questions and ensured everything was cleaned and functioning properly. I appreciated his attention to detail and professionalism throughout the process.

We always call All Temp when our furnace or air conditioning needs fixing, and specifically ask for their best technician. They've worked on our system twice now and we're consistently impressed with the service. Our tech is considerate and thorough, making sure everything is set to perfection before leaving us to enjoy the season. He also offers helpful tips to keep our equipment running smoothly for years to come.

While we don't know all of their team members personally, Marvin has established himself as our trusted go-to guy. We appreciate knowing he's inspected our system and given it a clean bill of health before the really cold or hot months arrive.

I'm extremely pleased with All Temp's service. They arrived within a couple of hours and completed the job in 20 minutes flat. The initial quote was straightforward, with no surprise extras. Technician Frank came highly recommended and indeed delivered excellent work, explaining key things to watch out for if my furnace fails again. Given the chilly weather outside, I'm thankful for their prompt service. Frank's professionalism shone through during his visit – he genuinely provided valuable insights that put my mind at ease.

My old furnace gave up on me and I called All Temp, who sent a technician named Marvin within 30 minutes. He was pleasant, explained my options, and acknowledged the age of my furnace - no pressure to replace it. Instead, he got the necessary part ordered and installed the next day. Early the following morning, Marvin showed up with the fix and even took care of any new issues. His professionalism and kindness impressed me. I'd highly recommend Marvin for your heating needs; in fact, I think he should be employee of the month - his service was top-notch.

Called AllTemp for emergency repairs after a leak from my furnace. They responded quickly and sent technician Brandon out right away. Brandon was knowledgeable and professional, explaining the issue to me and my husband in detail. He also took the time to show us alternative techniques for navigating our keypad. We were extremely satisfied with Brandon's service and the resolution he provided. AllTemp truly delivers when it comes to emergency furnace repairs - I can attest to their prompt response and expertise.

I'm blown away by this team's service - 10/10 would highly recommend. My brother-in-law vouched for them, and they exceeded my expectations even further. I usually plan to write reviews but had to do this one on the same day because it was that impressive.

After a disastrous experience with another company over two weeks of freezing temps, I called in tears. Jack was incredible - kind, empathetic, and explained everything clearly. They got me booked for the next week, which was a miracle considering my situation. Luis and David were my team today, and they were outstanding. So kind, thorough, and worked tirelessly to get heat back into my home. The positioning of the furnace was extremely tight, and both guys were committed to getting it done.

The area left was spotless after their all-day work, and I finally have heat. Tonight, I'm cozy in my warm home, feeling at peace. You can't put a price on that kind of satisfaction! If you need HVAC assistance, call them ASAP - they're truly exceptional and worth every penny.
