Today (7.13.26) I had GMS Heating & Cooling come out to do a regular maintenance on my air conditioner & split. We have been using GMS for years and a nice young man whose name is Eugene first called me and stated he would be at the house in 10 minutes. Eugene was courteous, knowledgable, professional and explained everything in detail and knew all the answers to my list of questions. This company is top notch and we already knew that. :-) I'm just giving a shout out to another employee that deserves the recognition. Kudos to GMS for finding Eugene! Add this young man to the list of ALL the employees, Ed & Glenn who represent GMS Heating & Cooling. Thank you and we appreciate you. read more

I highly recommend for any HVAC needs. They installed central AC in my house and did a wonderful job. They were friendly, knowledgeable and very clean. They worked long days to make it happen as quickly as possible. Can't say enough good things about the work done. read more

GMS has been top notch... technicians have all been extremely knowledgeable and able to answer and fix all of my concerns. Highly recommended as of now they have a customer for life read more

Top notch business here. Very polite, professional people who actually care about doing everything right. I needed to replace the furnace early in '24 and GMS really did a wonderful job. They gave me several options at various price points, with no pressure or hard upsells. The install was scheduled for 8am, and they showed up precisely at 8, ready to rock. Last month, I scheduled a clean & check to make sure things were still good. The tech was ahead of schedule and called to see if it was okay to show up early. (Sure!) He found a small part that he thought should be replaced, which was promptly ordered and installed free of charge, covered by warranty. I'm glad I found these fine folks, and will stick with them! read more

Folks did a great job selling/installing our new low pressure boiler. After instal service was terrific too. Their Boiler tech Jason is super professional and I value that from my handyman days in meatpacking when I worked with lots of hvac and refrigeration folks, good techs make the magic happen. GMS is never "not busy" so hit their website and call to arrange things. I am old so I always call the day before a visit to see how their workflow is going etc. just common sense. Love their dedication to the public safety community too. read more

GMS just install a New York ac unit condenser and coil. They did a great job. Ed quoted me an excellent price for a side discharge ac unit. The technicians Dillon and Alex was very professional and polite. I will definitely recommend and use them in the future. If I could give more than 5 stars I would. read more

Hands down the best hvac people I've worked with. They've installed brand new air conditioning, fixed broken boiler valves, repaired our hot water heater and we plan to use them for pretty much all of our future hvac repairs/replacements. Great rates, awesome service and most importantly experts in their craft. read more

GMS Heating and Cooling of Morton Grove Illinois, was recommended by a family member. I lived about 40 minutes away and they were happy to drive out for an estimate. I had them install a new York Furnace, Condenser, and Coil. They did a fantastic job! I was pleasantly surprised a system humidifier/dehumidifier was also installed as I had overlooked it. I can pass on my portable room unit. They uninstalled the old rusting equipment from the 80s, which created a huge mess through the basement, stairs, and garage, which they cleaned up and left spotless! They were very knowledgeable and professional, answering all my questions. When I went online to register my warranties, they had already done it for me! I couldn't be happier and highly recommend them! I'm terrible at remembering names, but Thank you so much! read more

I cannot thank GMS enough. My parents furnace pilot light went out this morning and my father called and spoke with Eddie the owner to see if they could come out and fix it. Without having him schedule an appointment he told my father that they will come today and get it taken care of . What a great relief that was for my father as the temperature us expected to drop tonight and into tomorrow. THANK YOU GMS!!! read more

We just had a new York furnace and AC unit installed as our previous units were over 22 years old and the originals. Glen responded super fast, especially given it was the 4th of July weekend. He was thorough in explaining the issue with the old units as well as what to expect moving forward with installation. Dylan led the installation crew and was PHENOMENAL! His entire team was super efficient, conscientious workers and cleaned up after themselves. I can't give this company a high enough rating! We are incredibly pleased with the workmanship and will be having them back next year to replace our units on the 1st floor. read more

So I'll admit I'm a bit bias. Eddie is my son in law. But... ya wanna know how good he is? Here's a perfect story. Because of a conflict, Eddie wasn't able to make another long distance family related service call. Previously, he's driven downstate to my son's house to replace his furnace when my son was laid up with a serious health issue. He's driven to my father's house (90 yrs old) in the Milwaukee area, on a moments notice, to fix his broken HVAC system in the dead of winter. This weekend, he sent his wife (my daughter) to our summer cottage with some tools and a box of parts to fix our old furnace. He walked her through everything over FaceTime and she pulled apart and reassembled the fan and cleared a jam. She found that a bat was stuck in the fan keeping it from turning. While I'm proud of my Daughter, who has limited experience with tools and repairs, it shows that Eddie is a true HVAC expert. He doesn't only threat family this way. Actually, it's more fair to say that he treats everyone like family. read more

Thank you GMS! read more

We had GMS put a new HVAC system in our home today. I would like to commend GMS for doing a phenomenal job. Dillon, Gerardo, and Jose were the installers. They were on time, very pleasant, and extremely knowledgeable and experienced. They worked non-stop throughout the day and got the job done in a timely manner. They cleaned up and left the job site spotless prior to leaving. I highly recommend CMS for all your HVAC needs. Thank you, Eddie and Glen. You guys are the best!!! read more

They are very professional and polite. I have both my AC and boiler system's maintenance by GMS yearly. read more

Great service by Glen and crew. Very reasonably priced and was patient in explaining all the details.

We had our furnace and A/C replaced. GMS installed both. Ed and Glen are the best! They are professional, full of knowledge, and have years of experience.

I found GMS online and decided to schedule a service call. I felt the technician was very knowledgeable, friendly and politely answered all my questions about his inspection of my 2 furnaces. Their pricing was very reasonable. I will definitely keep GMS as my "go to" privider for all my home HVAC needs. read more

I can always trust GMS to be professional, honest, courteous, thorough and neat - Glen is my go-to for any issues w HVAC. Today, he came masked up for my boiler check in anticipation for the upcoming winter. He was thorough as usual, explained the process, patiently answered all my questions and rendered considered advice regarding the water heater and the boiler. Not only that, he took the time to bleed a couple of the radiators AND fixed my thermostat that was incorrectly installed. And then vacuumed the area to boot! Thank you, thank you, thank you!!! I cannot recommend GMS highly enough! read more

To me, by far the most impressive aspect to me was how incredibly professional all the employees were. They were extremely polite, extremely careful with the equipment to not damage anything my house, put everything back exactly as it was before, and left my house cleaner than when they came. On top of that, their work is top notch and the prices are ridiculously modest. Do not look anywhere else for heating and cooling services. read more

The absolute BEST. More than five stars. Honest. Dependable. On time. I so highly recommend GMS Heating and Cooling of Morton Grove, Illinois. Fantastic company. read more

Called and talked to Ed. I asked for an estimate for a new furnace and he gave me a quote over the phone. I asked to come a take a look and he did. While discussing our options I asked for an estimate for the whole system as well. Ed gave me a few options and I went ahead with the whole system (furnace, A/C compressor and coil) by York. They included humidifier as well. The cost was lower then other bids I got for the same level of equipment. Plus they included 10 years labor warranty. We scheduled installation in two days. Dylan and his crew came in the morning. They were very professional, answered all questions I asked, protected the floor and surroundings while they were working, cleaned up everything very well afterwards. Everything was done in one day. So far everything is working well, I had a chance to use both A/C and the furnace. Could not be happier. Thank you! read more

GMS is awesome! I had a broken hot water heater and called them for a quote. Ed was very professional and took the time to explain the process and pricing...which was way below the market. His team came the next day and installed it in a flash. They also are furnace experts so I had my furnace inspected and they gave it a tune up. Highly recommended! read more

I am a GMS repeat customer. I had my hot water heater installed 4 years ago, it is still running strong. At that time I asked Glenn that if my 20 years old furnace need to be replaced. Glenn was so honest , he said no problem why change it. For peace of mind and trust GMS service for the next 10 years parts and labor warranty , we had our 25 years old furance and 15 years old A/C replaced by GMS dream team. They are vey professional, very polite, wear mask and keep the working area clean and neat. I trust GMS and support our local business. read more

Truly a great company, Ed is amazing, feel very secure with him and know we are getting an honest price with amazing service. Would highly recommend GMS, used to be with Skokie Valley Heating for years and so glad I switched, never had the same trust in them. So hard to find a great, honest repairman. He did work on my work on my furnace, same day service, amazingly fast and efficient a few months later needed to replace my water heater and he was wonderful in suggesting just the size I needed, great guy... my search is over. read more

I was referred to GMS by my best friend. Call and spoke to Ed on the phone and he had Glen meet me at my home a short while later on the same day. Ed was a pleasure to speak with over the phone and Glen was informative, kind and friendly. Both were an absolute pleasure to deal with. It is extremely hard to find honest HVAC guys. These guys are going to be my go to from now on and I will be referring all of my friends and family in the future. Fair, honest and excellent work. Please do not waste your time calling anyone else. Thank you Ed and Glen, it was a pleasure meeting you and I look forward to doing business with you for many years to come. GMS is awesome. read more

It is so hard to find honest and trustworthy vendors these days, but that is what you get with GMS. Ed always gets back to me right away, within minutes. He makes time for me whenever I need it. He does great thorough work and explains everything. It is very obvious that he cares about his customers. I can't say enough good things about GMS and will definitely be using them for all of my future heating and cooling needs. read more

Gms replaced my 20 plus year old furnace. Although it didn't go as smoothly as planned, they rolled with it and spent the whole day getting my new variable speed up and running! Lots of hard work and zero complaining. Ed and glen are a pleasure to deal with and are more than fair when it comes to pricing. Highly recommend!! read more

Absolutely impressed with this company. They're local, they're efficient, and extremely professional. I'm a repeat customer in that I've had my water heater both replaced and serviced by them and also had my furnace issues properly diagnosed and repaired by their skilled hands. Their prices were fair and their dedication is top notch. My most recent experience had them come the morning after I called (at 8PM mind you) to ask about issues with my water heater. They tried to diagnose it over the phone, and when it didn't work, fit me into their schedule to come by and check out the issue in person. Not only that, they sourced the part in the same day, and came back later that evening to replace the defective part. I am super impressed with their dedication and DEFINITELY will be sticking with them going forward. Their staff is warm, willing to help, and they do great work. If you're looking for heating and cooling help, call them first. read more

Highly recommend GMS Heating. My hot water heater (leaking) went out and he talked me my options. We talked about tankless as well as the correct sizing for my tank. He was very patient, responsive, and knowledgeable. He had his partner out the following day to install a hot water tank. Thanks GMS and Ed. read more

All I can say is they are great! Our Air Conditioning went out at about 4am We called at 730am and it was fixed by 9am! Fast ,professional ,friendly service. You can't ask for anything more. I am going to recommend them to everyone! Great prices too! read more

When our heat went out during the coldest weekend of this season we didn't have to worry about a thing thanks to GMS Heating and Cooling. All it took was a phone call and Ed and his team were at our house ready to replace our 30 year old furnace. We will be using GMS for all of our future HVAC needs! Highly recommend to anyone who is looking for an honest and professional company that provides fast and friendly service. read more

Amazing customer service. I called Friday around 5 pm and left a voice mail. Ed called me back 5 min after and said his technician was in his way back from a job and can stop by. Glen arrived around 6 pm and by 7 pm I had a working AC!!! read more

GMS is the ONLY place I will ever call or pass along to friends from here on out!! Brilliant service. Very professional and helpful. Our Boiler was not working properly due to some previous work we had done by other vendors. Glenn came in, assessed the situation and resolved the issues as well as outlining others that may cause larger issues in the future. Additionally, Glenn took the time to walk me through how the boilers in our home work as we just purchased the home and I have never had to maintain a boiler before. They were even nice to our Hyper Hound who loves visitors (Sorry about that Glenn and Andrew!). I wouldn't go anywhere else. read more
