Heating & Air Conditioning / HVAC near Glendale Heights

“I recommend every aspect of this company when it comes to keeping you cool. I reached out to Steve two weeks before my son's wedding and he came through for us. In a 30x80x10' outdoor tent his system kept all of our guest very comfortable for five consecutive days @ a temperature of 104 degrees. I thank Steve and his crew Alex, Josh, Dennis and George for their professional service when we needed it.“

“Adam in Knoxville Tennessee helped me out big time... He deserves a raise for what he had to do... 100%Services: HVAC system maintenance“

“Lucky us! Borter Heating & Air Conditioning (BHAC) came recommended to us by the sellers of our new home. Since 2018 each BHAC technician/employee has always been professional, friendly, honest, and knowledgeable. BUT nothing compares to the work they performed last spring on the AC unit installed by a home warranty company contractor last summer. BHAC discovered an endless list of issues that needed repairing. They returned several times to fix the problems and ensure the unit was running correctly. Ability, perseverance, conscience … Each technician went above and beyond! They even fixed our outdoor spigot.“

“Brandon was very helpful, fixed the problem, and offered several recommendations about how to prevent a reoccurrence.“

“Very professional. Did a great job. Will definitely recommend Elite Air to family & friends.
Thank you“

“Great family business! Every single gentleman who walked through my door was very honest, professional, and kind. They did not try to work me at all. When I discovered I needed a new AC, I got quotes from multiple companies over about a month period. Different people tell you different things, so I had a difficult time trusting most of the companies I received quotes from. I was having a difficult time finding a balance between someone I can trust and reasonable prices. And Grays Mechanical delivered just that, along with great customer service! I worked with Alex a lot throughout the month of quoting, and he was wonderful! Always willing to help and answer any questions or concerns I had. This was a learning process for me, and he was very patient with me. I appreciated him so very much! During installation there was a slight issue, so I was fearful that I made the wrong choice and perhaps was conned. But they were very willing to rectify the mistake, which confirmed for me it was just a mistake, and those happen. The owner, Mr. Dan Gray, fixed the issues for me, and I appreciate him taking his time to correct the situation. Overall every single person from that company who came by (overall about 7 of them) were very kind, honest, patient and professional. I could tell by their employees that it is a fair and honest company, and that is something I greatly appreciate.“

“Quick response. Honest and professional. Maintenance packages are awesome! Keeps my piece of mind knowing the knowledgeable staff is always honest and professional!

9/12/2024 had new Furnace/AC installed, Angel and all the team are super professional and honest! Giovanni was very paitient with all my questions (and thru our Permit process) on which units would be Good, Better,Best and Fantastic options. The estimate format was easy to read, compare and proceed with estimate. TRUSTWORTHY and highly recommend!“

“I will recommend them hands down. I call them last night and they were willing to come out on a drop of a dime. Technician was prompt and knowledgeable. He diagnosed the issue got the part and I was up and running. He took the time to explain the process and answered all my questions. If your looking for a great company that cares call them. Trust me you won't regret it.“

I had Maxson replacing two ACs and one furnace for my home. The process from quoting to installation was very professional and smooth. Steve is very knowledgeable and trustworthy. Highly recommend!“

“The Technician arrived a few minutes early to perform the furnace tune-up. He also performed the A/C tune-up earlier this year. The company is professional and pleasant, and they answered my questions throughout the appointment and cleaning. A neighbor recommended them, and I’m glad I decided to go with Mel-O-Air.“

“The techs that came out were professional and knowledgeable! They were able to make it out same day and fix it without having to do extensive repairs, only took them about 15 mins to get it back up and running! Highly recommend if you’re looking for a company to fix your HVAC!“

“On Thanksgiving morning our furnace went out. I called the company that we normally used, but got no response right away. I called a couple different places and finally got through to Ragano Heating. They were able to come out shortly after I called. Esteban the technician found the problem, but didn't have the part to fix it in his truck. He left and came back with a part that would work and would schedule an appointment later, once they had the correct part. He was there when my family started to arrive for Thanksgiving dinner and he got the heat working just in time. They came back the following week and installed the correct part as promised and it didn't cost me an arm and a leg. I already recommended them to a friend.“

From start to finish, their professionalism and expertise were top-notch. The team was efficient, knowledgeable, and went above and beyond to ensure everything was done right. Not only did they complete the job quickly, but they also provided exceptional customer service throughout the process. I highly recommend this company for all your HVAC and refrigeration needs.

July2023. Excellent experience. Lou called to confirm appointment and arrived early. Lou took time to carefully examine the system and issue and provided me very detailed explanation of the issue and provided a solution. The price was extremely reasonable. I would highly recommend Lou and Armbrust!!!

We had Steve out here recently and he was fantastic too. Extremely polite and knowledgeable.

Armbrust is top notch.

We had Alan out here. Another great plumber!!“
