A-A Mechanical

Roof top mounted Central air conditioner stopped cooling over Memorial Day weekend and none of the other top rated AC companies were available until more than a week later. Walter was flexible and showed up Sunday morning. We agreed on a price up front. He diagnosed and fixed the problem at a very reasonable costs. I appreciate his honesty, flexibility to meet a customer’s dire need, and professionalism. Definitely will use him again and will be recommending him to others. I compare Walter to the great mechanical I found in Naperville. Highly recommended!

Walter is amazing! Super knowledgeable and talked me through the whole diagnostic. I would highly recommending using this company if you are having an issues with your heating or AC.

Walter was awesome. Super friendly. Gave me a quote over the phone and could schedule me that week. It was quick furnace check. Price was exactly what he quoted. And again, just a really nice guy. Thanks Walter!

I had been having problems with my furnace and had several different repair opinions. Walter did a thorough diagnosis, assessed the problem and provided enough information to me so that I could make the decision it was time for a new furnace. He answered my many questions and did a return visit to make sure the furnace was safe until I could replace the unit. Very, very helpful!

A-​A Mechanical is one of my favorites! Walter did his usual thorough job. When he left, my furnace with in great shape and I knew everything I needed to do for future work. Highly recommend!

I called A-​A this morning and left a message. Walter called me back within an hour and said he would be around Noon or call. He called back 20 minutes later and said he could come now… YAY…the opposite of Comcast. I pretend to be mechanically inclined, so I decided it was a blown blower motor. He could have gone with my terrible diagnosis and gouged me. He determined it was low on coolant, which caused the compressor to freeze up. I’d turned it off over night so he put more coolant in and we’re back in business.
I’ve been reading the posts while Walter is working on our upstairs system. He strikes me as a guy who is good at his job and who defends any low ratings with the truth of what happened. Use him if your a decent person who wants competent work done. Use someone else if you’re a curmudgeon. I’ll use him again… unless I decide to become a malcontent. :-)

Called when our AC quit on a 90 degree day. Walter was at our house within the hour and fixed the flux capacitor in just over an hour, which included getting up on our roof and going to get the new part. Nice guy, really appreciated his quick and professional help.

I contacted Walter at A-​A Mechanical after I received what I thought was an inflated estimate for an air conditioner from Integrity. Walter came over on the day that I called him and arrived on time. After he examined my furnace and air conditioner, he patiently explained his assessment and answered all of my layman questions understandably. His estimate was lower than Integrity’s. Throughout the whole process of replacing the furnace and air conditioner, Walter was the consumate professional, providing me with frequent updates as the work progressed. Since today is the first hot day we’ve had since the installation, I’m happy to report that the air conditioner work great, and it feels good to have a contractor that I can trust. I highly recommend A-​A Mechanical without any reservation.

I called AA Mechanical and they were able to come out right away to fix the furnace. The part was still under warranty so the only cost was for the labor. I was amazed at how quickly the problem was solved.

I called A-​A Mechanical (Walter) at 8am this Saturday morning, because my forced air furnace went off during the night and wouldn’t go back on. Walter got there by 9:30 am, and even though I was sure that the programmable thermostat was malfunctioning, he went into the furnace logic board, and found a loose wire, and within 5 minutes the furnace was up and running again.
He also checked a few other things (heating element, etc) to make sure that everything else was ok. He also said that since I he had serviced my furnace in the past, and it was such an easy job, he didn’t charge me for the call. I’ve never had a serviceman for any appliance that ever did that before.
I’ve used A-​A Mechanical a few other times in the past (we have 2 similar furnaces in our building), and he has always been prompt, fixed the problem quickly, and his charges have always been reasonable — no matter what day or time.
I’ve owned many buildings over the years, and Walter is one of the best in the business, and I recommend him highly.

I called AA Mechanical around 6pm last night (Wednesday), my heater wasn’t able to get my condo above 62°. I was able to schedule an appointment that fit within my busy schedule for Thursday evening. Walter called back within a couple hours and was able to fit me in this morning before my work day began. He quickly diagnosed and explained the problem with the unit. He had my unit fixed and running within 30 mins of arrival.
Top-​notch service all around. Prompt, professional, and reasonable pricing. This was my second time using him and will definitely call on him in the future.

Walter was prompt, courteous and efficient. I highly recommend A-​A Mechanical.

I called AA Mechanical at 8:00 PM on a Tuesday evening when my furnace began clicking off. I was able to schedule an appointment for 4:30 pm the next day (the earliest I was available) and the technician arrived promptly to diagnose the problem. He seemed very knowledgeable about heating systems and proved to be an expert in his field.
The furnace was quickly restored and I felt that I was charged a reasonable fee for the service provided. I will absolutely use this service again.

After leaving messages with three companies and not hearing back from them, I called A-​A mechanical at 9:25 pm. I reached Walter while he was at dinner, and he agreed that he could come out that night. My heat had been out for hours at this point and my fingers were turning blue, so I was grateful to learn that it was only $ 25 more for him to come out that same night instead of waiting until the next day.
He texted me when he was 10 minutes away, and was at my door within 70 minutes from the time of my call. He was able to replace the control board and get my heat back on fairly quickly.
It is worth it to note that I was completely comfortable with Walter working on the furnace while I was home alone – it is never my first choice to have a maintenance person in the house late at night, especially when I’m alone, but he was very professional.
I would recommend Walter’s service.

Let me start by saying that Walter was very fast and arrived on time (a little early in fact) in the northern part of Chicago, which was appreciated. He finished the job and got it done, which is what needed to be done.
That being said, I must say that I was extremely displeased in the attitude and the overall rip off job that was ultimately performed. Walter’s attitude from the moment he stepped into my house was that of someone that is doing you a favor and not of a business transaction. It was a Saturday and he made it very clear that he was taking time out of his weekend to be here. If you’re in the business of repairing a furnace, either work the weekend during your busy season or don’t. I don’t care, it’s up to you, but you don’t need to be a prick about it especially since it’s your own business. I have to work weekends too and know its part of my job. He had the choice to be there, no one forced him.
$ 125 diagnostic fee. Ok, I get it, you need to be paid for your visit. No worries.
$ 600 for replacement part and labor, plus the original diagnostic fee, so total of $ 725. Total labor time of 1.3 hours (which included the diagnostic time). Total cost of replacement part $ 60 (brand new on Amazon). Let’s do the math here. Even if he marks up the part to $ 100, he’s charging me $ 417/​hour for labor.
Unless you have no other choice, I’d go elsewhere. I would have given 1 star but for the fact that he got the job done.

Walter has serviced my heating & air conditioning unit for the last 6 or 7 years. It pretty much breaks down every winter. He always does his best to squeeze me into his schedule – so appreciated. He also explains what the problem is and what needs to be done. His prices are very reasonable, and I’ve never felt that he’s trying to sell me something that isn’t necessary. I highly recommend A-​A Mechanical.

Walter is great, give him a call.
Of course the furnace goes out the first week Chicago was hot and like anyone else who had this issue I was scrambling to not only find someone to fix the issue but to do it fast.
Walter was the only company of three that was able to get to me that same day. He came out and diagnosed the issue immediately and fixed it within an hour. The next day my tenant’s AC went out as well. While I wasn’t thrilled to pay for two service calls in one week, Walter made it easy to get them both done and in the end we all slept comfortably.
I plan to use Walter in the future and recommend him to all of my friends.

I initially wanted to go with City & Suburban based on great review. Unfortunately, based on my address (South Loop), he apologized and said he does not service my neighborhood due to distance from his work place. He then recommend his buddy A-​A Mechanical. So I called Walter and gave my address. He said he was booked for the next two days so I made appointment for the first available date and time which was Friday at 10AM. I asked if he could come any sooner than 10AM and he said he couldn’t. So I said that is fine. He then told me he would call on Friday before he heads to my place.
Keep in mind that I was taking my time off from work to be at home to fix this problem.
Friday 9:57AM, still no call, so I called him and asked him if he is on his way. I thought if he was on his way but late for 10 – 15 minutes, that is understandable and I could deal with it.
When I reached him on the phone, He said «Ugh, what is your address?»
Needless to say, I told him that he doesn’t need to come anymore.
I have a job and was taking time off to be at home so that my furnace could be serviced. I was planning to be back to work by noon.
Because of Walter not keeping his word, I just wasted 3 hours of my time not being able to be at work and my problem is still not fixed and I will have to find another day off work to fix it.

I call Walter for two reasons: 1. He knows what he is doing. 2. He placed a sticky business card on my heater and I always refer to it when there is a problem with my mechanicals.
I find Walter knowledgeable, upfront, and quick. He always comes the same day I call and I’ve called on two separate occasions. He fixed our issues and we haven’t had many problems since.
His rates seem in line with industry standards and I would and probably will use him again.

Walter is the best. I own a building in Chicago but live out of state and he was able to diagnos and fix an issue one of my tenants had in one trip changing no parts. The same issue had gone unresolved through five service calls and two parts replacements with another very large Chicagoland HVAC company.
While Walter was there he also noticed some dangerously overheating ductwork that the first company had not seen and he was able to fix it the same day by working into the evening so my tenants would have heat.
A-​A Mechanical is going to make sure that your issue is solved in a timely, responsive and honest fasion.
