Mike and his crew are as good as it gets. They are really professional, knowledgeable, and punctual. Mike was great at helping us figure out what we needed to get dual zone AC installed, and then his crew was efficient and cleanly in getting it all done. Everyone wore masks and was super safe. Thanks guys! read more

I contacted them without a reference because they were one of the few HVAC companies I could find that would service underfloor heating. It was easy to book an appointment for an estimate online and I received a response back quickly to suggest recommended times. The technician, Kamil G, came out and was professional and efficient. Within a week their 2 technicians came out to do the work and they showed up early and on time and stayed late to ensure that it was working properly. When they noted an error in how they set something up, they called it to my attention and corrected it right away. Their supervisor came back the next day to check the work and demonstrate how to use the system. I received 3 different quotes for this work and Global had the best pricing and was definitely the easiest to work with. I would strongly recommend them for your needs and I intend to call them back for future work. read more

I do not recommend them. They were supposed to tuneup my hvac and were in and out within minutes. Months later I also just found out. They replaced my filter with the wrong size. If they missed something this simple I wonder what else they didn't do correctly. Don't waste your money here. They will not check properly and when you need your hvac in severe weather, it will stop working. read more

The capacitor in our AC unit blew during the heat wave. I called half a dozen HVAC repair places, including some I've used before, and if anyone even answered no one would be able to come out until we'd all melted. I gave Global Heating & Cooling a call and it went to voicemail as well. Not even five minutes later, my phone rang and it was them actually calling back. I had to schedule around a neighbors schedule to get access to the AC unit, which made things a bit trickier, but Global found a time the very next afternoon, days before anyone else could make it. They actually called the next day to see if they could show up half an hour early, which was shocking given the heatwave. They had everything running within 15 minutes (it was a simple repair that just happened to break everything), and had left before the actual service call was scheduled to start. For only having a twelve person outfit, they can seemingly cover jobs that much larger businesses aren't able to. Very happy I found these folks. read more

Prompt and professional service with a day of appointment, but pricing felt exorbitant for the parts and labor ($500) to replace an A.C. Capicator which took under an hour of tech time and a part that's like under three digits. Will consider again in a pinch, but would definitely suggest shopping around and hesitant from making this a 'go-to. An update following the businesses feedback- I have no qualms with the diagnostic fee, it's the rate charged for the repair. I received several other quotes for this specific repair for several hundred dollars less. Still steep seeing what the repair actually entails, but in line with what you'll see on Angies list. I made the mistake of agreeing to the repair before doing my homework and unfortunately this is business that is happy to turn that into cash. If you're not HVAC savvy either do your research or be ready to be pay for your ignorance! read more

Our air conditioner broke down right right on the onset of a string of 90 degree days. My husband received an outrageous quote from Four Seasons and we were in a funk. Fortunately, I reached out to our amazing real estate broker, Matt Liss, who assured me that Kamil and his team had the best service and prices in town. I'm so glad I listened! Kamil quoted us a price for the same Lennox AC that was $2,200 less than Four Seasons. The exact same unit! And, he said his team would be there the very next day to install it. We found the Global Heating and Cooling team to be knowledgeable and courteous with a quality that's rare these days -- honesty. Global Heating and Cooling is now our go-to HVAC source for life and I am happy to spread the word. read more

Damen came out as promised the next day. Our unit was so old that he told me up front that he couldn't work on it. He then spent the next 20 minutes, even though he was super busy and was unable to fix our unit, explaining what the problem could be and which companies actually still service old machines like ours. He only gave me an estimate for a replacement when I asked and never pushed any other service on us. Also, even though I wanted to pay his service fee for his time stopping over, he refused. I can't say whether or not he does great work as he didn't work on our system. However, I could clearly tell he knew his trade by the information he shared and his quick appraisal of our situation. Furthermore, I can say he operates his business with integrity which, along with the actual work quality, is just as or even more important. read more

First and foremost fast service. Showed up with masks and were very professional. They diagnosed and repaired my issues with our floor heating. Not pushy and things are working great. Will be using them in the future for my HVAC needs. read more

We had our AC go out on the first really warm day this year and GH&C were able to get out to us within 4 hours! Mike is a very personable and knowledgeable guy, he explained what needed to be done, gave us a couple options and answered all of our questions (even when he was clearly busy and trying to provide the same attention to his other clients who were having issues in the new summer heat). He had two techs out the next day to do the installation (one of the guys, Pauly, was fantastic and made sure we were aware of everything he was doing) and came back after they were done to make sure everything was working correctly and again explain everything to us. He also gave us a few pointers on how to care for the new system and our other HVAC systems, which is invaluable information. Our new AC was up and running by 10:30am (less than 24 hours after our initial contact). I'm thrilled with the customer service and care we received and will recommend Global to everyone I know, including others in my building. I've used Four Seasons in the past and the difference in everything from the first personal interaction on the phone to the speed of service to the work itself is astounding. Global is miles ahead of them. Thanks Mike! read more

Professional and prompt service, highly recommend. Paul was extremely knowledgable and was only too happy to help a first time home owner out by showing the process as he went. Price was reasonable given the amount of expertise and knowledge Paul had of all the different systems in our 3 unit condo building. We had all of the HVAC systems checked thoroughly! Change your filters people! read more

We have been working with Global Heating and Cooling for the better part of a decade (on rental properties as well as our own home). Kamil has always been a trusted advisor and always goes above and beyond to ensure that the job gets done right, on time and within budget. In addition, his responsiveness and communication throughout the process helps you feel as though your job is the only one that he cares about. Those that have worked with HVAC contractors know that good customer service and quality workmanship can be hard to find. We recently bought a townhouse and the home inspector missed the HVAC unit's warning signs that it was about to fail. When the HVAC faltered shortly after moving in, Kamil and his team were quick to rescue us with a beautiful new Lennox system and we couldn't be happier. Bravo, Kamil...thanks for keeping us cozy and comfortable! The Nelsons.... read more

Quick response and service but I felt oversold, overcharged, and I question the quality of the work. Global Heating and Cooling is definitely big on the "hard sell". Instead of fixing the problem, they aggressively pressed us to replace the entire unit for $4,000! "If it was up to me, I would just buy a brand new unit". After digging a little deeper into the sales pitch, they finally admitted that they could fix it for only $200! When I told them that's all I wanted (and could afford), they continued pushing me to buy a new unit. When I didn't fall for it, they pushed me again, this time to at least replace a key part for an extra $1,000: "If it was up to me, that's what I would do...if I wasn't going to buy a new unit (if you do we'll give you a discount)". When I asked them just to fix it to get it running, they called back less than 10 minutes later saying they tried, and although it worked, they now needed the extra $1,000 to keep it going! Based on the way they described "the fix" the less than 10 minute follow-up call seemed nothing less than suspicious. I was in a pinch and didn't have time to get a second opinion so I shelled out the extra $1,000 knowing that I had been fleeced by a dishonest repairman (enough so that I'll be watching my credit card statements for more extra charges). The good news is that everything is working (now) but based on the experience, I will NOT be surprised if something else mysteriously breaks in the near future (and if/when it does, I will NOT be calling Global Heating & Cooling). read more

Our a/c went out on hot August day, and Global made it to my place on the same day to diagnose the issue. We ended up needing a new condenser which they installed first thing the next morning. At all times Mike and Patrick and their team were communicative, punctual and polite. It was a messy job and these professionals cleaned up every bit work debris in the house, thank you so much for this! Global is my new go to for all HVAC work. read more

I had a problem with my AC unit and they solved it quickly! They showed up 3 hours after I called them, just amazing!

I am a homeowner and Global Heating & Cooling was the only company to assist with our air condition issues (during 89-degree temps) when placed our urgent call. I was verifying costs with another friend of Heating & Cooling and their prices are great. I would use them and recommend them to anyone. read more

If I could give this company 10 stars I would. Mark is amazing and very honest & nice. He fixed a problem with my tankless water heater that 6 other places couldn't fix. He did it in less than an hour and for a fraction of the price. If you want honesty and quality this is the place for you. Their communication and follow up is also excellent. 10 stars! Thanks Mark, you saved the day! read more

Very happy so far, they replaced my a/c and furnace today. The space was very inconvenient and I could see it was a struggle to work in there but they kept at it, made all the custom bits they needed on the spot and got it done by working late. From what I can tell the price was fair. Would definitely recommend. read more

Adding a follow-up review to say that the major project we embarked on (relocating a humidifier, which necessitated some new duct work and rerouting of water pipes) went great. Mike's team was terrific, did the job well and left zero mess behind. I absolutely recommend Global Heating; they were much more knowledgeable than competitors we have worked with over the years. read more

I had a motor go out on my HVAC unit in my restaurant. They found a new motor and replaced it within a few hours. They are now my go-to company for any future HVAC problems. They are knowledgeable, professional and friendly. I highly recommend their services. This easily is a five star company. read more

Nobody likes it when our appliances break. Specially your AC on one of the hottest days and a Saturday as well. Mike and his crew came out to assess the situation and talked my husband and I through the diagnoses. We ended up having to replace our whole unit. The only difficult part was they couldn't come back till Tuesday, but that was not their fault. They arrived when they said (8am on Tuesday) and within a few hours we were up and running. I am so thankful for their expertise and fast service. Will definitely be having them back out to do the yearly maintenance. THANK YOU!!!! read more

We called Global recently because our unit wasn't cooling adequately and then stopped with an error registered on the thermostat. When I called Global, they responded right away and were flexible around our availability. When Mark came out he was thorough and thoughtful carefully diagnosing the problem. After a short service call, the unit was up and running ready for the hot hot summer ahead. We have loved the Fujitsu/Halcyon split AC unit that we installed in the basement to supplement the main rooftop AC. It serves as dehumidifier without blasting heat inside and is equally energy efficient. read more

Mike and Mark are fast professional and affordable. I described the problem over the phone and had an estimate before even arriving at the job. They were in and finished with the job in 10 minutes and our AC is working better than ever. Thank you guys and I will share with all of our friends in Bucktown your contact!!! Don't look anywhere else for neighborhood for your HVAC repair. read more

This company and team handle the job seamlessly from start to finish. They were able to diagnose the problem within 15 minutes and have it fixed same day. Other companies that I had out to assess the problem could never figure it out. Thank goodness for Global Heating and Cooling. I am an extremely happy customer. I will be recommending you for years to come. read more

I spoke to the owner Kamal and explained that my condensation pump on my AC Unit went out. He scheduled me an appointment for the very next day during the hot Memorial Day weekend. Paul came and was very prompt and professional. He installed a new pump and advised me that my old unit would probably need replacing in the near future. He did that without the dreaded sales pitch. The price quoted for the work done was reasonable and fair. I would use them again. read more

Paul and team were great. He came within 2 hours for the service call and was on time for the furnace installation. Paul explained the issue with my old furnace and helped me make the decision whether to repair or replace. He was courteous and responsive. Once the installation was complete, he talked me through the registration and warranty process and walked me through how to set up my new thermostat. Finally, in a price comparison on Home advisor, my all-in cost was below the country's average for a furnace plus installation. An all over good experience. read more

Professional, efficient, reasonable pricing. Especially appreciate them taking time to explain the issue without talking down to me and providing tips for the future including basic maintenance without pushing any particular service or product. Service call completed and issue resolved in less than 24 hrs from initial call. They were running a bit behind but called to update me multiple times which was very considerate. Would use them again for any HVAC need. read more

Installation of a new coil and outside unit comes with assurance of professionalism and integrity unparalleled in HVAC industry . Upon swift departure and a promise is made to return in order to attach a severed air duct to the furnace to facilitate the installation . Paid in full . Big mistake . Other deficiencies of their craftsmanship noticed . Screws holding coil's housing not secured , holes in a duct hastily taped over generating whistling sound . Since June I have contacted Kamil and his partner 4 times about the above . Each time they promise to call back to arrange for completion of their work . That never comes to fruition . That is where in my opinion the benefit of the doubt expires . The review well earned . Injoy . My advice : steer clear of these slick liars . read more

Split system outside air conditioner unit had been broken down (the compressor was shot or the motor was seized) for a few weeks and after exhausting all options for repair I started calling around for estimates on a new system. Global Heating and Cooling offered the best deal for the best system and Mike and Mark came out the same day I called to see what I was working with. They arrived quickly and even ended up knocking another $100 off the price of the future installation. After only a 2 day turn around they came back and installed the new system. They were easy to communicate with, helpful, respectful, and thorough in their work and answering any questions I had. The new unit is working great. I would recommend Global Heating and Cooling to anyone in the Chicago area. read more

Fast and professional service! Our air conditioning stopped working in the middle of a heat wave and I called for emergency service. Within 20 minutes, a technician had arrived, and 10 minutes later he had diagnosed and identified a fix for the issue. I will definitely be working with Global for any future HVAC needs! read more

Great service! Honest and friendly customer service. Mark, the owner, was great! Very helpful, on time and easy to schedule. They installed a new AC unit for us. Very competitive pricing, great unit! Paul, one of the install guys, was very helpful on the day of with keeping me informed. They were very clean with install and worked with our condo president well. Would highly recommend these guys and I love that it is a family owned business in the neighborhood! Will use them again. read more

Scheduled an appointment 6 days ago and they give me a window of 9-3? Really a 6 hour window but made anyway. Day of app at 1:15 I have to call them to confirm and they say they can't make it today sorry tried calling you earlier. No they didn't. I'll try someone else, thanks read more

My air conditioner went out on me on a Thursday evening. I requested help on yelp. Global heating responded first and gave me an idea of what the problem would be. Came out the next day, less than 24 hr, showed me the problem. Fixed it within 15 minutes, charge a reasonable price and was on their way. If only all my issues can be fix this fast. Awesome customer service and friendly. read more

Owner Kamil did a great job at my house! Replaced the furnace in just few hours, i can tell he's professional at what he does.

Amazing service! Just called this morning in the worst Chicago weather day -50 windchill and got on the list for service. The team came under 2hrs and were nothing but professional and knowledgeable. I would use again and recommend to everyone! read more

Best company ever! Our A/C gave out at the worst moment before an event at my home and after calling a couple places and having to wait till the next day I thankfully found Global!! They were at my house within the next hour and fixed my A/C. Even though it was an older unit they managed to replace some parts inside and have it work again within about an hour rather than having me spend money on an entire new unit. They used booties inside and cleaned up their mess after so it was like they were never there. I highly recommend them for all your heating and cooling needs! read more

Top notch service! The tech that came to service my unit (Paulie), was very professional and punctual. Their customer service is great and they were able to fit me in quickly. Paulie was very knowledgeable about the issue and took time to explain to me what needed to be done and how to avoid the same issues in the future. I would highly recommend their service. read more

Mike Did a fantastic job both technically and with customer service. They were able to get me an appointment for the very next day. They called and said they were available much earlier if I was around. This was great as they solved the problem much quicker. Once inside the unit they not only quickly identified the issue, solved it and tested it, but also made sure to explain what was going on and how to prevent further issues. As well as some other recommendations that might help. As seamless of an experience as I could have hoped for in a stressful situation. Recommend to anyone read more

Our furnace broke at 6am on a winter-y morning , and Paul came by 9am. They didn't just say "replace the furnace!!" They were trouble shooting the whole time. The outcome was to change the furnace, and when they did they were respectful and used booties inside my house, and cleaned up afterwards. We are very pleased with the service. 5 stars! read more

Global Heating and Cooling were precise, punctual, and professional. Kamil and his team did a fantastic job replacing the HVAC system in my home. Kamil was beyond helpful with advice and tips on which direction to go and what type of systems make the most sense for our home. His team showed up 8 am on the dot and were very professional communicating with me throughout the whole process. Would recommend them to anyone and would definitely use their services again. read more

We worked with Kamil multiple times for various reasons. He always come out the very next day and is courteous, professional and reliable. He installed our entire HVAC system in our old house and serviced our air conditioning when it stopped working in the middle of the summer in our new condo. He is the only person I call for HVAC issues and I highly recommended him! read more
