The technicians efficiently resolved the issue and had me cooling within minutes. I appreciated their friendly and expert demeanor - I'll be choosing them again for any future needs.

GMS is top-notch. Smart, honest, punctual, and outstanding work - they truly excel.

Heat stopped working around 8 pm. Contacted GMS, spoke to Ed, who sent a technician within 30 minutes. Good service and fair pricing. Highly recommend, will be a repeat customer for sure.

We needed AC help in the midst of a particularly scorching summer. Tired of dealing with Skokie Valley, we reached out to GMS instead. They claimed to be overwhelmed, but somehow managed to squeeze us in - we were literally just four blocks away from their office. When Ed showed up, he gave me a plan and invited me to wait for Glen that night, who would fix the issue then. Both Ed and Glen were understanding, explained what they did, and seemed genuinely invested in resolving my problem. I felt like they really cared about helping me.

This company operates with integrity, delivering high-quality work at competitive rates. Their team, led by Glenn and Ed, prioritizes customer satisfaction and avoids pushing unnecessary upgrades or sales. I strongly endorse them for any HVAC installation or maintenance requirements.

Our furnace gave out during a cold spell and this company saved the day with fast service. We initially thought it was just a minor issue, but when it wouldn't budge above 65 degrees, we knew something was wrong. They re-ran with a new appointment after I had to cancel the original one. Some unexpected things arose, but they handled them professionally. Their response was impressive and I'd definitely recommend them again without hesitation.

Used GMS for AC and heating installation. Ed's team was on time, professional, and provided great value. The price was spot on and the job was done exceptionally well. We'll be using GMS for all our future HVAC needs.

I'm extremely satisfied with GMS. Their service is top-notch, thorough, and reasonably priced. The team is professional, and the owner is straightforward and honest. Every interaction, from initial contact with Ed to working with his crew, was positive. I highly recommend them.

I needed a new gas valve for my furnace, but most heating companies won't sell parts directly to consumers unless you're a contractor. Luckily, Ed at this place does sell to individuals and helped me troubleshoot the issue before even buying a part. After that, he found the replacement valve quickly and it was reasonably priced. What really stands out is how honest and helpful Ed is - he genuinely cares about his customers. His customer service is top-notch, which is rare these days. I highly recommend using this HVAC company; they have an owner who truly puts customers first.

They excel in honesty and professionalism, setting a high standard for their industry.

GMS is top-notch. I wouldn't put anyone else in charge of maintaining my furnace - they're dependable, trustworthy, efficient, and do a perfect job on the first try. I have no reservations recommending them to anyone.

GMS is top-notch, dependable, and budget-friendly. Ed and Glenn always get back to you quickly and take the initiative to fix the issue right away. They won't push extra work or try to sell something you don't need. On a Friday night, they came to our AC emergency on short notice - it was impressive.

I've been using another company for my HVAC needs, but I recently switched to GMS for a routine A/C tune up at my rental property in Morton Grove. The owner came out and assessed the unit, chatting with me briefly about everything that seemed fine.

He took some time to thoroughly clean the exterior of the A/c unit, which he didn't charge me for. It was a nice surprise given the usual price tag is $69. What impressed me most was his honesty - if there were any issues, he would have pointed them out and likely charged me for the work.

Instead, he left me feeling confident that my system is in good order. He's local, has years of experience in Morton Grove, and genuinely seems like a trustworthy guy. If you're looking for reliable HVAC service, I recommend giving GMS a try.

After nearly three decades, our AC compressor gave out on Tuesday evening. After scouring online reviews and recommendations, we reached out to GMS for an estimate. They installed a new unit just yesterday, demonstrating excellent customer service with friendly representatives who answered all our queries. The installation was done professionally and left the site spotless.

This company genuinely puts its customers first. When my parents' AC compressor died during COVID-19, a different local firm refused to fix it under warranty due to lost revenue from servicing annually. In contrast, GMS showed up and completed the job ahead of schedule. As someone who works in the HVAC industry, I'll be recommending them for new installations and maintenance to all my customers. The owner personally followed up on my questions and responded promptly. It's refreshing to see a local small business like GMS that stands behind its products and installs them correctly. Overall, their dedication to customer satisfaction is impressive.

We recently had our furnace and A/C replaced with GMS's help. Ed and Glen stood out as exceptional installers - knowledgeable, experienced, and true professionals. Their work speaks for itself: honest, reliable, and top-notch service. If you're looking for a trustworthy heating & cooling company, skip the rest and choose GMS; you won't be disappointed.

I recently had a garage furnace installed by this company and was thoroughly impressed. They showed up exactly on time which is no small feat considering how often contractors run late. The price they quoted stayed consistent even after some unexpected complications arose during the job, which added 1.5 hours to the original estimate. Their professionalism and positive demeanor were also a standout. This level of service is incredibly valuable to me. Given their excellent work, I've already inquired about getting them to assess my old furnace, which is over 25 years old.

Ed's team is very reliable, polite, and efficient. His workers are expertly trained and tidy in their work habits. The AC installation process was seamless and stress-free. Ed's company deserves high praise for a job well done; they're worth recommending without hesitation.

I've found an even better service than after hours emergency repairs from a closed competitor. I called at 4:30pm and got through to someone who said they'd send someone over soon. A few guys showed up and did the job right, which included fixing some issues with my AC unit that another company had messed up. They also spotted a gas leak that was overlooked by the other firm - no extra charge for this. The whole team was efficient, reliable, and fair. If you need last-minute help, these guys are worth calling.
