They are honest and trustworthy! They came out quickly during a busy time of year to service our hvac system.

Wow the charger won't work and customer service said they never heard of that. It will only work or charge one battery at a time on my dual charger for a lawn mower. I said I can send it in to prove it. They said no but a new one sorry. read more

We have hired Julian several times at our condo building in Rogers Park. He does annual service for the building boiler and our water heater. He also did boiler repairs and helped with our radiant floor heating system. read more

I had my gas furnace and water heater replaced after 20 years. The replacement with Green Works LLC was a breeze. They were reliable, knowledgeable and easy to work with. This helped me make my decision on what I needed and wanted for my condo. Julian and Wally did the installation and hauled the old units from the properly as well. I was extremely impressed with Green Works LLC and recommend this company. read more

I've used GreenWorks three times now, and each time has been great! The previous two times were at a different house for a furnace and A/C tune-up. Most recently, I called for a boiler service and got an appointment for about 10 days later. I was given a service window of 9-12pm, and the technician, Ismael, called me just after 9 to say he was nearby. We are new to owning a home with a boiler, and Ismael took the time to walk me through proper boiler maintenance. He never tried to upsell me, and he said my boiler looked great! Ismael also took the time to walk upstairs to my tenants' unit to troubleshoot some heating issues (most of which were user error!). Ismael found one radiator that may need to be serviced, and he told me he'd work on getting me a quote to fix it soon. GreenWorks has always been prompt and polite, and I know they will continue to be our go-to for boiler maintenance. Thanks, Julian and Ismael! read more

I used green works to fix my broken down ac recently. Tony did a great job fixing the issue quickly and explaining what was the problem to me. The price they charge was much lower than I expected. Would highly recommend greenworks to anyone that needs HVAC repairs. read more

Great service, professional, quality and value driven. Green Works provided a fine hot water heating system to my multi-family project.

We just had "Tony" over here to check on our air conditioning. He was on time, so efficient, very pleasant and professional. Its humming along beautifully now and cooling us off in this miserable heat. Highly recommend him! read more

Reached out to Julian when our hot water heater was do for replacement. He was super responsive and quick to provide a solution/suggestion for the new model. Even better he was available within 24hrs. Couldn't have been nicer in person and did the install quick and efficiently. Wouldn't hesitate to recommend and use in the future for any plumbing work. read more

Just had another service call and Green Works is still awesome as ever. Julian came early in the time frame that he gave me. He is still efficient, informative and affordable. We have enjoyed this service for years and have never been disappointed. We highly recommend them. read more

I am so grateful that we found Green Works! We have needed their help for a variety of things and they've been responsive, reliable, and have solved all of our problems. We have worked with Julian and Ishmael and they've both been a wonderful part of making our home come together. We first contacted green works to see if they could sound proof our HVAC room, which they said they didn't do. But they did help us prepare for the soundproofing that another contractor did for us. The contractor said green works set them up perfectly to do the work they needed. I was also pleased that green works came out to see my problem without a guarantee of work. We then needed them again when another contractor messed something up and our hot water stopped working. Green works to the rescue! We needed them again when we installed a smart thermostat! The Eco Bee has been working great. We then needed them when we realized our AC wasn't properly installed. They were so empathetic to our problem and even encouraged us to find the original installers to save some money under warranty. This wasn't ideal since we didn't trust those folks. Julian and Ishmael communicated all possible options to us and they were very honest about how feasible the solution might be. Today is my birthday and we have AC! Super grateful to have Green Works a short text away! read more

Julian is very knowledgeable in his business. He takes the time to explain how systems work to help solve problems individual to your homes heating and cooling needs. He is an honest small business owner and I'm happy to have found someone who not only knows what he's doing, but cares. read more

We just replaced our 18 year old AC and furnace. Julian's communication with my husband was prompt and his quote was a few hundred below a couple of competitors. What we appreciated most was his honesty. He not only didn't try to upsell us to a more expensive brand, but he talked my husband out of paying for certain features in a new AC that my husband thought we needed. We've already referred him to a few of our neighbors who are doing to do business with him. read more

Such a great experience with Green Works! My radiator went out in the middle of the night on a single digit night, so I was freezing. I had a very prompt response on Yelp, and the tech was out within only 4 hours! The technician, Ishmael, was great! Very professional, was also very friendly with my dog (added perk!), and explained everything he was doing. He identified a number of issues from the installation, spent time to call tech support for the radiator, found previous wiring issues, and gave clear call back instructions. The call itself was $95 and there was a "miscellaneous fee" of $85. Not completely sure what all that entails and wish more details were provided instead of just "miscellaneous." However, Ishmael was present for a significant amount of time and provided great service so I was satisfied with the price. Will definitely use again - may even look into using Green Works to transition from radiators to central heat/air! read more

Julian at Green Works LLC is extremely knowledgeable and responsive. We've used his services for years. I especially want to commend him for his honesty. Yesterday he put $515 back into my account after HE CALLED ME to inform me that I had overpaid on a previous service. The fact that I had never questioned the bill makes his integrity even more notable. read more

Hired Greenworks to perform a boiler check up and the process couldn't have been more pleasant. Easy to communicate with, on time, friendly, and explained the whole process in detail. read more

Always reliable, easy to schedule and coordinate times and always shows up on time. They replaced my furnace in the aftermath of a blizzard and suggested that my AC, also 14 years old at the time, probably still had a few good years. 5 years later it's still going strong, they just serviced it with no issues. Saved me tons of money over the past 5 years, will definitely continue to use them and recommend to others. Payment online is also very convenient! read more

I have a five-year-old through the wall air conditioning unit that is not cooling as it has in years past. I called Green Works and Julian answered. I told him my issue, thinking it just needed some coolant. He said he can't do it and I asked if he could refer another company, and he said no. He told me he doubted it could be fixed. That seemed really odd. I called this company based on the reviews here. Seems this place is very limited in the scope of work they do and they certainly need someone better that can converse with client calls. Not impressed at all. read more

I'm am the president of a condo association for an 18 unit building. Our heating system recently experienced a catastrophic failure; our heating pipes froze throughout the first floor, resulting in dozens of leaks in multiple condos. Julian and Ishmael worked overtime to restore heat to our building. We were nearly certain that we would need to repipe the whole system, but Julian and Ishmael came back and continued to work until the issue was fixed. They explained the whole process and presented our options clearly, and Julian was very transparent with his pricing. read more

They had a great price ($95) to clean our boiler and ($30) to bleed the radiators in our three unit condo building. The next day, one of the radiators was leaking from the bleed valve and Julian came back out to close it. He then showed me how to bleed the radiators and how to put more water into the boiler to raise the pressure. It's a simple enough task that I would have been scared to try on my own. Our heating system is old and uneven. The first floor units are always too hot and the second floor is always too cold. Julian worked patiently and thoughtfully to come up with an inexpensive solution for us. Both Julian and Ishmael were great. I would definitely use their services again. read more

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. read more

I have a boiler and the AC system you get when have a boiler. Julian was the first person I called for service years ago after purchasing my first home. He is very honest, has fair prices, and does great work. This past winter, I had to decide between an expensive replacement part for my extremely old boiler (that would last maybe 2 years) or to replace it with a new unit. Julian talked me through both options. I decided it was more cost effective to get a new boiler installed which he did the very next day. He also has an amazing team of folks working with him. I just had work done on my AC unit for the first time, Green Works really knows what they're doing! The person who did my repair was efficient (they came out the day after I called) and thoroughly explained what he was doing. He even cleaned off my compressor outside. I seek out reliable, trustworthy professionals when I need to make repairs to my home. I wish I could give Green Works ten stars! read more

The heater and the air condition in our home seems to be broken. I heard that a certain company can fix my problem and that is Green Works. I immediately contacted the company and they are very responsive that I already got a appointment on the next three days. The day came and Julian and his crew came to our home. They were polite and professional. Julian explained to us every little details about the heater and the air condition. I listened to him properly because he knows a lot of things about it and I must say that he is reliable and expert on it. They immediately fixed everything and they tested it and they make sure that it is properly done. They also offer to check them on every season. They had done a great job since both of the heater and air condition are perfectly working so far. Also, the payment is way better than any other companies and I really recommend this one. read more

I reached out for a quote and instead of responding with available times, they just said they were "booked." I guess they are booked for infinity and beyond. Odd and rude. read more

Julian is the man! I've used his services several times now and he's always very honest, open, fairly priced and gets the job done right the first time around. He has my business from here on out! read more

Julian with Green Works was amazing!!! He came out on short notice during the Chicago Polar Vortex after our furnace went out. Julian troubleshooted our furnace until he was able to get it up and running. Not only did Julian get the furnace up and running, he showed me what he did, and why it worked (in case something happened again). Julian was so patient and helpful. I'd recommend him to anyone and everyone. Thanks, Julian and Green Works!! read more

Did a fantastic job replacing our hot water tank. GreenWorks did it it timely, and was the best quote that we got out of 3 repairmen.

Julian is the best. He said he'd be here in one hour and he was here in 30 minutes. He quickly diagnosed the problem with my furnace and he went above and beyond to resolve the issue. He was very polite and courteous as well as very professional. I kind of had an idea of what I would pay and it was about half that estimate. I would highly recommend green works. read more

We had a leak with our water tank. Julian was able to come out to us to fix it on the day before a holiday. We really appreciated that since it was a situation that couldn't wait. We had plans that evening and were relieved that he texted us to confirm he would be coming and then showed up on time. He knew what was needed, brought everything, and charged us a fair price. He was personable, knowledgeable and great at communicating. We will be calling him again when we need any of the home services, which his companies work with. Thank you Julian and Greenworks! read more

We have two preschools in Ravenswood and Lakeview and have worked with Julian and Green Works for the past three years. They are always quick to respond to our needs, which are usually emergencies or need to be repaired right away. I highly recommend the quality of service, fairness when it comes to quotes and pricing and efficiency . I really appreciate that in a vendor. read more

If you are looking for an honest, reputable HVAC professional, then Julian is your guy! Julian services our unit twice a year, and since it is over 20 years old, we know at some point soon, it will need to be replaced. Unlike other HVAC companies that we used in the past who pressured us to have the unit replaced years ago, Julian doesn't operate that way. We trust his opinion implicitly and know he isn't trying to upsell us. Green Works is a fantastic company in every way! read more

Julian comes on time, explains everything clearly and works quickly. He is pleasant to work with and will always do what's best for your home. What seems like a crisis to you is no big deal to GreenWorks! I highly, highly recommend them. read more

A few years later and my end of life AC crapped out. Used Julian for the whole replacement of roof evaporator and condenser coil. He even comped my charge a bit since HE had installed the last condenser, albeit 5 years before. Whole thing took just a few hours and had comfy AC for the first time in a year. I will never call anyone else ever again in the Chicago area for HVAC needs! read more

I had a really positive experience with Green Works! Julian was quick to respond to me and set me up with his technician, Tony. He was polite, on time, and new exactly how to fix my furnace. I will be calling them in the future for repairs. read more

After asking for our contact information, they never got back to us. Waited two weeks. Guess they did not want the business?

Professional, friendly, efficient. I needed an old washer/dryer removed from my laundry room. However, there were two other appliances blocking the way through the door. Green Works came by and skillfully disconnected and removed my water heater AND my new washer/dryer, moved the old washer/dryer out, then reconnected the water heater and new washer/dryer. It was a big job that I was dreading, but I couldn't believe how smoothly and quickly it went. Highly recommended. read more

Julian is a great guy. I've called him several times over the years. Each time I was afraid I would have to dig deep to buy a new furnace or air conditioner but each time he's saved me hundreds or thousands of dollars by diagnosing simple repairs. He could have easily taken advantage of me but he's honest and knowledgeable, which is why I keep going back to him. Nice guy to talk to, too. read more

They did a great job doing seasonal maintenance on my HVAC system.

Pleasant, efficient, and conscientious team. Replaced my ancient A/C unit swiftly. Great communication.

Thank goodness for Green Works! Our steam boiler is about 10 years old and although we get it checked out every year prior to heating season, naturally occasionally it stops working. Well last night was one of those nights. I found Green Works on Yelp and called them at 8:30 this morning, having been unimpressed with past dealings of other companies. Julian answered and said he could be here between 12 and 3. He came at 12:10. Quickly diagnosed the problem, went to get a part and repaired it. Voila! Heat again. Julian is awesome. Two plusses with Green Works I especially like: there's no phone middle person, when you call you're speaking to the mechanic and they are local to me, in Rogers Park. read more
