Green Works, LLC

I selected this company when my furnace went out … based on the reviews. Thank you everyone for the good tips. Julien (spelling?) came out the same day. I gave him a quick assessment over the phone at 8AM. He was very knowledgeable, but he wanted to come early enough in case my furnace needed parts he didn’t have. Then I texted him my name & address — I like that, a verification of the time agreed upon. After 30 minutes of clean/​check/​fix and answering all my questions, it was an $ 85 fee (no parts needed replacing). Very reasonable. He politely wears booties. One note: they service the Chicago area, but normally don’t go much farther west than Skokie. Thankful he did for me since its the middle of January!

same day service on a zero degree day on my condo furnace. professional and fairly priced.

I was very happy with my service from Green Works. They took my call early this morning and had someone out the same day in the afternoon (b/​c that’s when I requested they come). The technician, Mario, was friendly, polite, and professional. He explained things to me as he went along and got us back up and running within an hour. The price was very reasonable and I will absolutely call upon Green Works again when my furnace motor blows, when we need A/​C serviced, or if any other needs arise. I’m enjoying the warmth now :)

This is going back a year or so, but Julian was so amazing I’m writing this now
My furnace went out in the middle of winter. I called Julian and he had a busy schedule but
came over within a couple hours on a Sunday. He diagnosed the problem right away; needed
some rotating circular blower part. Unfortunately Sunday, nothing was open. I’m sure I’m not
his only client but he came very first thing Monday to install it. Very reasonable pricing as well.
I also needed a new igniter and he told me if that wasn’t the (another) problem, he would come
back for free.
I’m starting to have problems again (15 year old furnace) and may have to bite the bullet
on a new furnace. Well, you know who I’m going to call!!!

Great, fast service. I called Giulian and was able to schedule a weekend appointment right away. My condo requires a certificate of insurance to inspect the AC on the roof, and he was able to provide that within 48 hours. During his visit, he was courteous and wore shoe covers. He also took the time to explain what he saw and readjusted a few vents for optimal air flow.

These guys are awesome! Mario was a lifesaver and was able to come check out our furnace less than 5 hours after we called with a condo association emergency (and after the person we originally had contacted was a no-​show). He was nice, efficient, very knowledgeable, and reasonable. I would highly recommend these guys to anyone in need of HVAC repair.

I can’t say enough good things about this company! Julian scheduled my a/​c repair immediately, showed up right on time, was extremely professional and very efficient, not to mention very nice. He was able to access the roof of my townhome with a 40 ft ladder, something most other contractors can’t do. Highly highly recommend!!!

Our family has used Julien’s services on several occasions over the last 4 years to tune up or fix our HVAC system and have always been impressed by the speed and attentiveness of his initial response, priority given, quality of his work, and competitive pricing. I couldn’t recommend Julien or his services any more highly.

Called Monday morning bc my ac was not working. They made it out the same day in the evening, AND they fixed it right away at a good price! They are also conveniently located in my neighborbood. I will definitely use them again :-)

Green Works lived up to the rave reviews already written. The service was timely, professional and fairly priced. Julian was truly one of the kindest and most thorough people I have ever met. And as an aside, he tried to help me get a bead that was stuck out of my 4-year-old’s ear — I dare another HVAC service in the city to beat that!!!

If you are reading this you are likely in the business for HVAC services, see below for my complete experience, but in short, an outstanding company with wonderful employees, fair and honest pricing and without a doubt the best HVAC company I have ever used. Green Works will take care of you and deserves your business.
I have been using Green Work’s for my furnace for the past 2 years for routine maintenance after moving to Chicago in mid-​2013 and have had the most prompt service and fair pricing of any HVAC company I have ever used; however the reason for my review now is that on a Friday evening in the winter I came home and noticed a foul smell coming from our furnace exhaust and called Julian about it. He not only took my call at ~8pm on a Friday, he offered to come out the following morning at 8am to take a look. He was able to astutely diagnose the problem, which was that the furnace heat exchanger was malfunctioning, unsafe, leaking gas, and the unit needed to be replaced and could no longer be used. He communicated all of this to me in a way that I understood and offered options for furnace replacement that same day.
Now this was a Saturday morning and an unexpected service call for his company. However rather than rescheduling a time to replace the unit, Julian was able to find us a new unit, with a top of the line carrier (and maximum energy efficiency), install it that day at a most fair price. Julian took his entire day at my house installing that furnace, hauling away the old one and didn’t leave to go home until 10pm, all so that we could restore heat that night, which in my estimation is going above and beyond anything I would have expected. Having your furnace break in the middle of winter is never something you want to experience, or pay for, but I feel really good knowing that the experience I had, and the money I spent, went to such a fair and deserving company.
I goes without saying that Julian and his company are outstanding, they are more than deserving of your business.

I live in Rogers Park and when I was looking for furnace repair, was so happy to see a company located here. Julian has been out twice now over two years, both ending up being minor issues.
Julian was prompt, professional and knowledgeable. The first time my heat went out at 6pm on a Sunday during –15 degree weather, thanks to snow/​ice buildup on our building’s vent caps. Called and he was here at 8am Monday. Second time was last month. Gave me a two hour window and was here 15 minutes early.
Very reasonable pricing too. Can’t go wrong with Green Works!

I’ve had Mario by twice for issues, once for a tune up on the AC, once for heating issues. Both times were great. So kind, friendly and helpful and got my issues handled in no time.
Highest recommendation.

Mario was a huge help and Green Works responded quickly and set up time to come out and clean our furnace. He was very explanatory and detail oriented and helpful in sharing what we could do to prolong the life of our furnace. Will definitely use again and recommend to others!

Highly recommended. They returned my call within 30 minutes, came out the next day (I called at 5pm on a Wednesday and they were here at 1pm on Thursday), and spent several hours with me assessing the problem, eventually discovering that my furnace was cracked and leaking on the inside. Mario was friendly, communicative, and very clear about all my options and their estimated costs. The price was very reasonable, and I would absolutely use them for any future needs. So glad I found these guys!

Does not serve south side of Chicago.
Look, they may be a great company but I wouldn’t know.
Because although it says on here «Serving Chicago and the surrounding area», they refused to service my residence on Chicago’s south side.
That is my only beef. But in their defense, they did give me a phone number to a service agent who does serve the south side.

Awesome, simply awesome.
Just to keep it short and simple (or atleast I’ll try) — our AC Unit broke down a couple of weeks back. I called several places and none of them seemed to want to provide their service because they «did not have a 30+ feet ladder» and I already had two guys scheduled to come out but backed off on the day of the appointment because of the ladder issue. Anyways — I call Green Works and speak with Julian. I explained my situation and to my surprise he says «I can come in today, what time works for you?» and sure enough, he comes to our townhouse within the next 1 ½ hour with a ladder that extends well above 50 feet and his partner (Green Works is only operated by and comprised of two people, Julian and Mario).
Julian worked on our unit for a good hour (checked the furnace, evaporator, motor, went up the roof and replaced the condensor — I’m not so sure what it was but it was broken). Mario replaced our Thermostat and took his time to stay longer and go through EVERY SINGLE ASPECT of the AC unit, I mean, EVERY SINGLE piece — this was beyond amazing and especially because he was done for the day with his work and just came to help Julian with the ladder.
These guys are awesome, friendly, personable, really enjoy and know their craft — they really took their time and not once did I feel like they rushed. They answered every little question I had. The price was very good and definitely competitive. They definitely earned my trust, respect, and also my business. I would reccommend Julian and Mario — Green Works LLC — to any and all.
Keep up the good work, fellas! You guys are great!

Plain and simple, these guys are the best.
AC unit stopped working so we had Four Seasons come out to take a look (they installed the furnace a year prior).
They confirmed that our AC unit was shot and needed to be replaced; Quoted us at around $ 4,500 plus $ 900 for a crane to lift the unit to the roof and were on their way.
Time to call around for a second or third opinion. We called Green Works to get an estimate — they came out and looked at the unit. After a little investigation, they were able to jump the AC and realized it needed to be re-​wired. Our wiring was shot.
They re-​wired the unit and got it back up and running, provided a ton of info and kept me updated throughout the process of fixing. The charge was nominal compared to what I had originally been quoted and I couldn’t be more relieved.
Highly recommended!

I would have perhaps given 4.5 stars because it was a little bit difficult to get hold of them — but then again, they were much easier to get hold of then some of the other companies I tried. So: 5 stars for you, Glenn Coco!
When the heat kicked on in my new condo, sh*t sounded like a prop plane. I’ve never had central air before but it occurred to me that this probably wasn’t right (when you have to turn the volume for Game of Thrones UP, you know something is amiss with noise levels). Also, the inspector had already found that the humidifier was shoddily wired.
So Mario came out and he was great. When he didn’t have a part needed to fix the shoddy original installation, he came back at a time convenient to me. I appreciated his patience with my questions — many of which were along the lines of «how do you work a thermostat?» And I really appreciate my new humidifier, which is not black with mold like the last one (ew ew ew).
Thusly: I plan to work with Greenworks in the future for all my working heating and cooling needs.

Mistakes happen; my pants would be a three-​alarm fire if I dared to call myself perfect.
Julian called me and called me and called me some more after he read my review; he doesn’t like to leave voicemails. Had he not left a message or texted, as he did, that would have been the end of the story. However, his overwhelming number of positive reviews, made it seem only fair to give him a second chance and take him up on his offer of a free inspection.
The second time around, Julian showed up when promised and apologized profusely. He’s a very nice guy and his apology seemed genuine — no excuses or argumentativeness whatsoever. He got down to business and inspected my furnace. He didn’t even seem to mind when my one cat, reprising her role as general contractor, supervised his work. I consider myself lucky I gave Julian a second chance because there was a problem with my furnace. I had the option of fixing or replacing the furnace; since it’s practically an antique, replacing it seemed like the smart thing to do. I was a bit concerned because my schedule over the next few weeks is crazy, but Julian was able to accommodate my schedule and provided the needed insurance paperwork to my building before work commenced.
Julian returned for the install promptly and got right to work. My new furnace was installed and aside from a problem-​free, more efficient furnace, it doesn’t even look like he was here. He’s really good about cleaning up all dust, debris, etc.
Like I said mistakes happen, but this one turned out well in the end. Despite getting off on the wrong foot, I would recommend Green Works.
