Our old thermostat stopped working and we had an Ecobee 4 what we had been meaning to install - called Greenworks at 7AM - and they were at our house in an hour - installed and set up the new thermostat including the power controller. Ismael was very courteous and was able to get it to work when it did not initially. Very pleased! So glad I called them.

We've hired Greenworks for years in two different condos for both routine maintenance and big ol' disasters. They are always kind, prompt and explain all your options. They never tried to push me to replace a failing hot water heater or furnace but instead offered a tune up at a fraction of the cost.

Julian (Green Works) is a true problem solver, skilled in his profession, honest, very professional, efficient, knowledgeable, extremely intelligent, a thinker and above all, he has integrity. As I have found out repeatedly, mediocrity (at best) appears to be the norm in the HVAC world. Not so with Green Works. His price was reasonable but to be honest, no matter what the cost, I would and will have him return in a heartbeat. The work done and the problem solving was superb. Julian and his associate, Mario, performed the work at my place on February 3, 2017, on time and on the scheduled day. I had a new furnace (Lennox 96% efficiency) installed by another well-known HVAC company on August 6, 2016 replacing my 10-year-old 93% efficiency Goodman. I had used this company for the last 10 years for yearly maintenance and other things (not critical such as this) so they were quite familiar with my system. Per this company, I needed a $3000 dollar part or a new furnace would be $6800. The recommendation was made that I replace the furnace especially since I had just retired and wanted to keep future large expenses to a minimum. I will not bore the readers with the problems that I had with the first company. That will be covered in their review and is not relevant to the quality of work done by Julian and Green Works. However, I do need to explain briefly what happened with the initial installers and why I had to call in another HVAC company. Since Chicago had had a mild fall, I didn’t fully realize the implications of this installation until November. My bedroom is directly above the furnace/storage room. The furnace vibrated the entire room, so much so that one could actually see and feel the chair vibrating and feel the floor vibrating. I called in the installing company again. They tried various remedies to fix it with their final recommendation being that I needed to put in a new cold air return, at my cost ($1200) and perhaps even a canvas connector (approximately an additional $2000), none of which I needed with my other furnace. Their suggestions for repair were unacceptable due to the layout of my system and all of the extra costs. That was their “final offer”. Needless to say, I could not have this furnace continue to vibrate my 110-year-old building and supporting structures and I could not trust this company to “fix” a problem that they caused and were unwilling to take responsibility for. So I started educating myself and looking for someone who could perhaps fix the problem. The Lennox company was not very helpful. Basically, the Lennox furnace that was installed in my building was too powerful for the existing system and short of reinstalling another appropriately sized and brand of furnace, "band-aid" remedies had to be attempted. It is rather like taking two additional medications to correct the side effects of another medication you are taking. I just happen to find Green Works and Julian via Yelp and Angie’s list. Not only did he come out to the house, spend a whole hour with me diagnosing the issues, making viable suggestions that would work for my system but he also answered every last one of my questions via e-mail and phone. Julian gave it much thought but quickly came up with an innovative idea for a return installation that did not take up 12 feet of shelving and a file cabinet in the storage room which the first company had wanted to do. And, very important, the return did not cause unbearable noise in the family room as he insulated it and, as I said, had an thoughtful and innovative idea for installing it that prevented this problem. In fact, the noise from the new return was non-existent. There is more. The new cold air return did not totally stop the vibration. It greatly improved it but there was still a slight tremor. Remember, my concern about the vibration was the effect over time on the supporting structures of my building. The canvas connectors would eliminate the vibration but at a major cost. Julian came up with another idea that he thought might help and would only cost $200 at the most. It was worth a try. This was basically a “padding” at the top of the plenum. However, the furnace and plenum had been installed so tightly against the wood supports that he could not get the “padding” in. The good news is that by manipulating the metal on the plenum and loosening some attachments between the wood joists and the plenum (without compromising its integrity), he was able to eliminate the vibration in the room above it and hopefully on the building. He did not even charge me for this. He also made some other suggestions to increase the efficiency of the system which I have implemented. We both agreed to live with it as is for the next month to make sure that there were no other major issues with vibration. As I stated in the beginning, I will have Julian and Green Works back in a heartbeat. Julian and Mario were great and are good, honest and intelligent professionals.

One of the best experiences with a service company ever! Julian and Marco was awesome, friendly, punctual, and very competent. They came out the day after I called them, easy to make an appointment. I needed someone to service a leaking furnace humidifier. Quick $25 fix! He had the part in his truck, installed it, and he was gone in less than thirty minutes. Nothing but a positive experience. Don't think twice about giving these guys a call!

If you are reading this you are 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. Greenworks will take care of you and deserves your business.  
I have been using Greenwork?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 chose him because I wanted to get the most energy efficient system and needed a knowledgeable and open-minded contractor (cost reflects energy efficiency upgrades and other repairs).  He continues to be responsive to questions about the system over email.  I will definitely use GreenWorks for future upgrades.

Julian came to our house early one morning to diagnose the problem (uneven heat from GFA furnace).  Julian determined that one large room had inadequate registers given the size of the room and number of windows.  He returned a few days later and added two registers to that room.
The improvement has been dramatic.  To me this shows that not only is Julian professional, punctual, etc., he is also quite knowledgeable about GFA heating. 
I will hire Julian again in the future as needs require, and I recommend Green Works LLC wholeheartedly.

Julian completed a diagnostic check of the furnace and had it repaired quickly.  He was also able to repair a poorly constructed duct line, completely clean two furnaces, and replace the venting which was showing signs of rust.

I am usually not someone who takes time to write reviews,
nor am I quick to praise. But after having called Green Works to my house two
different times, I have to write to say how impressed I am with Julian.
The first time I called him was during the heat wave of
2012. Our AC broke down. Without much wait at all, he came and quickly
diagnosed that the unit had never been installed properly. (The company that
installed it admitted this was true but since the warranty was expired, they
said I was SOL.) Julian fixed it ($450) and we?ve had no problems since.
The second time I called Green Works was during this year?s
flooding in April. Once I got several inches of water pumped out of our
basement, Julian came the very next day, took the motor out of the furnace,
dried it and got it working. Plus he fixed our hot water heater. Heat and hot
showers! How many flood victims were able to find that kind of service?
In both cases, what made Julian great was that he explained
what happened and what needs to be done. Unlike most repairmen or contractors,
he actually wants you to understand how things work. He?s a true craftsman who
takes pride in his work, and he goes the extra mile for you. On top of it all,
his prices are reasonable. I just wish there were more guys like him out
there.

.I have used this company before to great satisfaction, so when it came time to replace a failing 25 yr old furnace I called Julian at Green Works. He is prompt to respond, always returns calls and shows up when he says he will. I really appreciate that.  When he arrives, he is professional, clean, and highly educated about his profession. He knows if there are rebates available.  He explains the options available and doesn't push you to choose something you don't want or need.  He listens and will work with you so that your satisfied. The price is fair.  As to the work performed I am really satisfied.  My home is old and there were surprising obstacles (as always on a project) that had to be overcome and they were.  I am picky when spending thousands and from the new duct work, to the new  furnace install, to the humidifier  I am happy with the job done.  I will use Green Works again and will refer them to my neighbors too.

Julian is amazing. Have you ever met a nice guy just when you needed him? Our AC failed on one of the hottest days and the american home shield terrible contractor walked away without even properly diagnosing the problem. We called Green Works for an estimate and a second opinion. Julian came out ASAP even though it was after business hours, confirmed the diagnosis (it was dead) and also looked at our old furnace (which we found out was refurbished and 30+ years old--waiting to fail). He sent us an estimate that night and was extremely (as in compared to the other estimates, the most) affordable. In the end we went with another company that was slightly higher (since we're in a strict condo, it was not entirely our choice), but we would not hesitate to use Julian on another project. He is the best of the best. His diagnosis was excellent, he was very honest (and how rare is that when you deal with heating&a/c people!?!) plus he was clean, thorough, and professional. My daughter (18 months) ADORED him and she is terribly shy. Highly recommended!

The technician inspected our central AC system quickly and concluded that it was working well. He recommended better attic insulation to manage the heat. He explained everything he was doing and gave honest, clear information.

Julian was quick to reply to my call for estimates and quick to get started when we agreed to do the work.  His professionalism is unparalleled and he did the job for the exact quoted cost even though the process of relocating the external condensing unit turned out to be more challenging than expected.  Every time he walked through our home, Julian would put covers over his shoes to prevent tracking dirt and debris, and when the job was finished he cleaned up all the debris and even vacuumed the areas in which he worked.  The new HVAC system is MUCH quieter than our previous 16-year old system and so far everything seems to be working perfectly.  I would highly recommend Green Works for your HVAC needs and I will use them again for regular seasonal maintenance on the HVAC system.

Our furnace went out last spring on a Sunday and our usual service company wouldn't make a trip out to investigate. I found Green Works here on the list. They were highly rated and nearby so I called. Julian came over within an hour and checked out the furnace. The igniter was broken and needed to be replaced. He didn't have a replacement part in his truck and since it was Sunday, we couldn't just go out and get one. But he came back first thing on Monday morning with a replacement part and fixed the furnace and performed standard maintenance on it. He was very responsive, courteous and thorough and the price quoted was exactly what he charged. I plan on usual Green Work from now on instead of our older provider and I would recommend them to anyone.

From response to payment everything was quick, professional and businesslike, with no surprises.  Julian was as neat as a pin and unlike a previous experience with another company, I didn't have to clean up after him.  Price was reasonable and I will rely on Julian in the future.

Julian and Dmitri work together in tandem. They are always quick, responsive and accommodating. They are like partners but Dmitri is under another company and he works with Julian, while Julian is under Green Works and he works with Dmitri. They recommend repairs over replacements. They have been servicing my system really terrifically whereas other companies might have recommended a new system or something like that. They are really upfront and honest, and I would totally recommend them. When I had problems with my air conditioning shutting off, they suggested that we wait till the fall since I don’t really use the air conditioning on the first floor. They spaced out the cleaning, so it was a little more affordable. They are a smaller company, and I have had estimates from bigger companies. Their prices are very reasonable compared to the bigger companies. I feel that maybe because I am a woman, the people from the other companies treat me a little dumb and do not explain things to me. Julian and Dmitri explain everything. Julian is really easy to talk to and to get along with. The humidifying system to my furnaces has made my heating bills go down and made the system much more efficient. When I have had problems because I did not quite understand how to operate the system, if they were in the neighborhood, they would come by and help to make sure that it was turned on properly without charging me or charging maybe just $20 to come out. I feel that they are accessible and trustworthy. I would rate them highly, and I will never use anybody else ever again.

We have an non-standard central air conditioning system that operates on chilled water. I chose Green Works as they indicated that they have expertise in diverse technologies. They did not disappoint! Julian came out on the day that I called and promptly on the early end of the timeframe that he had indicated. The system was low on freon. He spent 3 hours inspecting all of the lines in the system for leaks and found none. He recharged the freon and told us that if it leaks freon again, that would indicate that the problem is in the heat exchanger. When I called the following week (it did leak freon again), he remembered me and promptly gave us an estimate on replacing the heat exchanger. We will do this next spring/summer at the beginning of the air-conditioning season. If you have anything other than a totally standard heating/cooling system, Julian is your guy!  If you appreciate superb professionalism, punctuality, expertise, and service, Julian is your guy!

Our heat broke for the billion time and I decided it was time to try a new heating company (even though I do like the one we've been using). This company came out fast & performed the service quickly. The tech was friendly and professional and I would call them again in the future for sure.

Julian arrived on time and inspected the humidifier throughly. His goal was to keep cost down and keep the old humidifier (which was only one year old but was never installed correctly). He finally advised us to buy another model that was more suitable for the furnace we have. He worked quickly and neatly. I am very pleased with his work and will hire him again for all future HVAC work.
