Best Heating & Air Conditioning / HVAC In Chicago

“We’ve been using Oasis for years! Hani is the best! Trustworthy and honest. Highly recommend Oasis!“

“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!“

“Fast, reliable, and professional service. Mr. Burris fixed our water heater quickly and for a great price. Five stars!“

“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!“

“I called Browns late Tuesday during a heatwave, and they were able to schedule a service appointment for the next day. The service call cost $125, but that amount goes towards any repair cost if needed so the initial call is essentially free if you need service costing more than $125.

The techs arrived exactly on time at the start of the appointment window, and quickly found the issues (dirty condenser coils, refrigerant top-off, and system sealant to address the small leak). Ramond clearly explained the impact of each along with the cost to fix, then confirmed which services I wanted and what my total would be before starting the work. I also appreciate that Ramond answered all my dumb questions about how air conditioning actually works; he's a great science teacher 🤓.

The cost was less than I expected for a next-day service (coil cleaning $239, sealant $285, and a few pounds of refrigeratant was $370).

During the payment process, the tech didn't prompt for a tip, unlike most companies. So don't forget to ask them for their Zelle/Venmo if you want to send a tip“

“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.“

“Great experience with Joe. He went through all the checks for the heater which was actually a commercial heater and air conditioner was able to diagnose the problem step by step“

“Great customer service Truly invested in providing best options for clients. They look out for customer safety, comfort while being competitively priced I would contact them for any heating issue“

“I was very pleased with the technicians knowledge & customer service. Will definitely recommend in the future.“

“City & Suburban has serviced our HVAC system twice, over 5 years apart. Each experience was positive. They addressed our needs, answered our questions, and didn't try to upsell us. Both techs were very friendly and knowledgeable. Today, Eddie showed up when expected and fixed our AC within 45 minutes. If you call the office, you may not get an answer if they're busy. But we entered a service request on their website and got a call back.“

“Brian!!!
Was soo happy with his repairs & assessment of other issues,
We specifically asked for him to come back & He did not disappoint 👍🏽
Thank You Brian 😊“

“Been using these guys for a few years, both for maintenance and for a new furnace when we needed it. They're always great. Alfonso today was particularly helpful.“

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

“Direct Improvement helped us navigate the American Homeshield nightmare as they serviced one AC unit and installed a new AC unit as fast as possible. TJ, Gorge, Iren, were all very informative and straightforward. Matt did an outstanding job with what was a difficult installation. I will call This company directly when we need service (after canceling AHS).“

“Tue service agent was excellent, polite, explained what he was doing and in getting my ac working.“

“Took me awhile to commit to replacing the furnace because I kept thinking it had another winter in it. Scheduling was pretty painless they had a slot witch was days out witch felt fast. The install guys were done before I finished working at my kitchen table.“

“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 …….“

“Very pleased w Jonathan and Abraham. Worked diligently, cleaned dryer vent located in a difficult place and returned the flow to normal. On time and professional. I will use them again“

“Personable and professional service. 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.“
