Best Heating & Air Conditioning / HVAC In Chicago

“Jorge was on time, early even! And was professional and thorough. We’ve been happy with All Temps service.“

“They gave me an appointment just days after I called. The technician called to let me know he was going to be 15 minutes late. Wow. He was clean, friendly and answered a couple questions I had. Amazing customer service!“

“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!“

“We just moved in and wanted to change a shower head, and it wasn’t happening until Mr. Burris promptly returned my call and checked out the situation to see if I could resolve it, but the shower head was really jammed and not going anywhere. He asked for pictures and came right over. He is super-nice, got his tools and fixed the problem and gave us some maintenance advice on removing soap scum and keeping drains clear. He is plumber of the year! If you’re looking for a plumber this is the guy to call!“

“I scheduled regular maintenance for my HVAC system with Browns Heating & Cooling. The technician was kind and arrived on time. He inspected the system, including the outside unit and air filter, and replaced the blocked filter. He also tightened loose connections that could cause problems if ignored. The appointment lasted less than an hour, and I feel more confident in my system's performance. I will definitely call them for my next maintenance check next year!“

“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“

“These guys are great! Dominic came out the next day to do a furnace tune-up and it helped kick on the heater again. Reliable, honest, and friendly, I will use them again!“

“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.“

“On time. Excellent service. My only concern is that it was very expensive and I was curious why two plumbers and two plumbing trucks came for a faucet replacement but maybe they thought it was a larger job. But except for the cost, they were terrific and very nice!“

“Very satisfied with the professionalism and honesty of Sergio and his worker, he gave me recommendations on how to keep my unit clean and advice on what not to do so that everything works properly, thank you and I hope I don't need a cervid or but if so I already know who call Brothers Heating & cooling“

“Great service with a thorough inspection and cleaning of furnace and a/c. I've had them come very six months for the past 6 years. Would recommend them without hesitation.“

“Best Service - Best Technician
Firstly, there is consistency. TDH techs are all good. But having the same one for 15 years is outstanding. Wally has installed our furnace, tankless hot water system, radiant heating in floor and ceiling. Secondly, the work Wally performs not only is outstanding but the details in laying out the radiant system is a thing of beauty. Shows the care that TDH puts into their service. Thirdly, is consulting on complex projects - TDH (Tim and Wally) did great work in consulting on the design. Few in Chicago would even quote on our needs for a tankless hot water and radiant heating. All of the recommendations worked out perfectly. For service Jacquie is always responsive - and on the few times over the years we’ve needed service she has been fast and very communicative. Highly recommend TDH for any HVAC needs.“

“The service from Direct Improvements was flawless. They arrived ontime. Diagnosed the problem. Scheduled a follow up appointment to install a replacement HVAC. They completed the project in 1 day. Their service was Impeccable.“

“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 …….“

“I had an awesome experience with my technician. Professional, explained the problem in detail and gave reassurance that the problem could be solved. I solve problems for a living. This young man did a phenomenal job.“

“Ceasar was the service man who tuned up our heating/cooling systems. He was very knowledgeable and did a very thorough job. He even cleaned the outside unit, no other service person had ever did that. Going forward we plan to give our business to AABAL“

“Outstanding professional service. Timely. Communicative. Clean. And most importantly, didn’t feel wronged. Would use again and refer to others!“

“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!“

“Excellent service from City & Suburban!! They were prompt, professional and fixed my AC unit quickly. Rob was my technician and explained everything clearly and left the area clean. Highly recommend this business for HVAC service!!“

“I have been with Ralph's Heating about 5 years for my property and overall about 40 years on properties that I work in used for our vendor we haven't had nothing bad to say at all .give them a try and all the employees Respectful“

“Arzet has always provided honest and quality service and products for my own home and all my real estate clients. Would highly recommend!“

“I contacted Burks heating with a furnace outage in the winter on a weekend and they came out and quickly resolved the issue and got my heat working. That was 2 years ago. I just recently had an air conditioner issue and they again helped out. I would highly recommend Burks fore any heating or AC services. Their personnel are polite and knowledgeable. Rose C.“

“Honest folks, Fair prices. They're upfront about services and costs, so no surprises with them. They are also pretty quick and are conscious of time billed. They'll let you know if something is really an issue before they start working on it.“
