Best Heating & Air Conditioning / HVAC In Chicago

“Second time for repair service and Oaisis exceeded expectations again! Tech was courteous & knowledgeable. He took the time to fully explain the current status, and future work needed on our system. Office also made an effort to try to move my appointment sooner- if I had been available. Above and beyond! Communication is excellent via phone and text. Tech was on time, and stayed for an appropriate amount of time once done to ensure the problem was handled.“

“We had a humidifier connectivity issue. Randy was the perfect man for the job. He did not talk much, he just got to it and fixed the problem. Great job!“

“Mr. Burris and his team are awesome! He and Rodney came to our newly purchased home after a serious gas leak was found by Peoples Gas and was able to rectify the issue. He actually saved us thousands of dollars. He also walked us around our new home and pointed out other items to keep an eye on and suggestions to address.

Thank you again, Mr. Burris. May God continue to bless you!“

“We had a great experience. Ed communicated well and was very responsive and personable. When Robert and Joshua came for the install they said they take pride in their work and it showed!“

“Quick responses from a professional company. Although it was peak season for AC’s, they were able to send a crew over within 24-hours. This was so critical for us with 3 young kids in the house and the temps rising to 85 degrees.

Angelique on the phone gave clear instructions on what I needed to do before the service guys showed up. Ramod & Eric were courteous and wore shoe covers as they entered the house. They took a quick look and knew what needed to be done immediately.

As a Realtor, I’ve changed many an AC units and their prices were very fair. We ended up repairing instead of a new AC unit. The repair was less than what he originally quoted. How is that for honest service?! Amazing!

They will have to come back for a service ($99) as we ran out of time.

I can highly recommend Browns Heating & Cooling without any hesitation.“

“Happy customer here. Received a response right away when I reached out to them. Deep technical expertise. Seen and done it type of person. You can tell. Quickly diagnosed the problem correctly. More importantly, I really liked how he took the time to explain what he was doing, what I need to do in the future, and things to lookout for. Very friendly attitude. At the end his price was reasonable as well. Thank you to the team.“

“Eddie and his coworker arrived promptly, were nice & polite, and explained their work well. I was able to see their work after. I requested they use a higher end 5-2-1 compressor saver (hard start kit) for my old outdoor AC condenser unit, and they were able to handle my request. They also cleaned up after themselves and checked my indoor unit without asking.“

“We had an emergency furnace breakdown and they were able to come and fix it the same day.“

“Reliable, Professional, and Trustworthy HVAC Experts

It’s rare to find a company that combines professionalism, quality workmanship, and genuine customer care. Highly recommend Arzet Heating & Air Conditioning, Inc. to anyone needing HVAC and / or water heater services!

I had an exceptional experience with Arzet Heating & Air Conditioning, Inc.! They have installed a new furnace, air conditioner, and water heater since 2024 for me, and the entire process has been flawless. For each installation, the team arrived on time, worked efficiently, and kept everything spotless throughout the project. Their attention to detail was outstanding—they made sure every component was installed correctly and explained everything clearly. It's very obvious that they are experts in the industry.

What really stood out was how they made me feel throughout the process: confident that the job was being done right and at peace knowing I was in great, professional hands. Pricing was completely transparent with no surprises and very competitive, which gave me even more reassurance. They also followed up after the initial installations to ensure everything was working perfectly and to answer any additional questions.

Outstanding service from start to finish. Thank you to Daniel and Luis, and all the other team members who ensured flawless installations! You are THE BEST!“

“The contractor came and stopped the knocking coming from the radiator that very disturbing for 30days. He even educated me on the radiator and why the knocking was happening. I really appreciate the help and information being a parent!“

“Good prices. Good work. Good clean-up. Highly recommend Mid-City. Streamlined my basement ceiling ductwork. House feels warmer on lower heat settings. Mission accomplished.“

“Alex from WAN-Tuck . Heating was able to turn my heat on after TWO - other heater companies could not …..I had my aquastat replaced by the second contractor that came to my home . However my heat still kept shutting on and off and eventually it didn’t turn on and my PSI was all over 50 / 60 / 70 The second contractor admitted he did not know what was wrong with my boiler…. That’s when I had to call. Wan-Tuk as they were the ones that installed it in 2008 Never had any issues till now 2025 I have never maintained my boiler ….. I never flushed expansion tank never did anything. I bleed my heaters here and there……. That should’ve been a clue to me of the quality of the work that WAN - Tuck provides since 2008 no issues / no maintenance till now …………As far as the second contractor that replaced the aquastat disrupted my PSI and did not know how to fix it … before new part was installed my PSI was between 15 and 16………… Alex from WAN-Tuck adjusted the temperature on the aquastat which was set above what it should be set for my boiler (the second contractor missed this detail) ….. Alex got my heat turned …… And my heat stayed on and didn’t shut off anymore….Alex tried to flush my expansion ( to regulate PSI ) but tank valve wouldn’t budge so I had to have it replaced ….. I still have my heat …… Thank you Alex from WAN -Tuk for being Courteous / polite and knowledgeable…..and for taking your shoes off before coming in my house / a lot of heating people won’t even ask…. The moral of my story is, I tried to shop around to save money, but in the long run, I spent more if I would’ve just reached out to Wan -Tuck in the beginning I would not have spent as much as I did on the first and the second contractors ….. in the end, Alex…. Diagnose and repairs were cheaper than the first two contractors and with good results heat stayed on my PSI went down to 20 after expansion tank was emptied and refilled …….“

“Excellent customer service and follow up. Technicians were professional and courteous. Did a thorough job of cleaning ducts and dryer. Repaired an elbow on the dryer vent.“

“Been using their services for a few years now. Cannot believe how great their service and honesty is. Thank you Nate and Diego. You guys have been so great!“

“Ralphs came to my home after me reaching out to American home shield they came. They gave me an estimated access to what was wrong with the air-conditioning unit And they came back and they changed my fan. If not the motor and I now have error again it was fixed within 30 minutes no more than an hour. I am grateful to them.“

We had a technician come over to get our pilot light reignited and instead of changing all components for the highest price, he went through methodically checking step by step. This was extremely customer focused and we felt that he had our best interests in mind.“
