"Our furnace went out the afternoon before Thanksgiving day, we called another repair place and made an appointment for Friday, they never showed up and were not returning calls. So we started calling around and got hold of Carlson's. They came over within half an hour and diagnosed the problem. The circuit board wasn't available until Monday but they had it up and running then and were reasonably priced. We will call them next time our furnace needs any repairs."

"HVAC 34 years old - furnace died in January (very cold spell) - needed emergency repair/replacement - G&R came out on emergency - checked furnace (unrepairable) - got quote - they replaced furnace and air conditioner (air conditioner at my request due to cost of freon charging) - they did all within 4 hours from my initial call - great work."

"Dave was very nice and professional. Gave me a fair estimate for a new system. Brett and Jake assessed the problem and determined that there was no problem contrary to what I was told by Temperature Docs "your system is fried, your only recourse is to buy a new furnace and air conditioner" for nearly $7,000! My air condtioner started working with a tweak of a knowing plier. I was not charged a repair cost only for the service call /diagnostic which was very reasonable. I asked Brett if my system looked "fried" and he said no. I was more than relieved that the situation was remedied so easily and economically. I was impressed by everyone's professionalism and most of all honesty. I would recommend this company to anyone need heating and cooling assistance. Best of all it is veteran owned!"

"The technician arrived within a half hour of our initial call. Although he did not have the part on hand he made a quick trip to their service center and returned immediately with what he needed. The technician was prompt, professional, and knowledgeable. I feel it's also worth mentioning that the technician is also a combat veteran who served multiple tours overseas and is in the process of becoming a licensed plumber. I think it says a lot about a company who hires veterans. I'll never call anyone but Regional Plumbing and Heating for the types of services they provide."

"On a Cold and Snowy 2nd day of Spring 2020, my heating system went out and got really cold in the house. Called Four Seasons to come out for an immediate repair. Four Seasons was able to come out within 2 hours. Technician was very knowledgeable and fixed the the problem right away and my furnace was up and running before the freezing night came. Thanks, Four Seasons!"

"Emergency. Furnace went out overnight. Woke up freezing. Called G&R Heating. They (Adam), responded within one hour. Furnace couldn't be repaired - provided quote that was acceptable and accepted immediately. New furnace (and air conditioner) was installed within 4 hours. Total lapse of time from waking up to a cold house to new furnace (and air conditioner) was 5-1/2 hours. Excellent and superior customer service. I now have the heat back and am toasty and warm again. Great work G&R."

"In October of 2024 I had the most excellent good fortune to work with Greenlink Energy Solutions as part of an ComEd Home Energy Efficiency project that included replacement of the furnace/a.c. and water heater, as well as top to bottom weatherization of my house. Even before the project started both Olivia and Jarron took the time to answer any questions and address any concerns I had regarding the equipment being installed and the overall scope of the project. Day 1, first up was a couple of electrical guys, quickly followed by Jarron and his HVAC team, Ben & Ryan. All on time and ready to get to it. Professional, pleasant and remarkably tolerant of my nonstop questions about the systems, the guys went to work and, other than a quick lunch break, worked nonstop, not particularly concerned about the clock but more about getting to a reasonable stopping place for the day. By the time they were finished, everything was operational, square and plumb, all pipes, valves, duct work and conduit looking very slick, orderly and professional. (5 stars just on the sheet metal work alone). Next up was the weatherization team with Nick leading the charge. Again, on time and ready to go. These guys, Zarek, Steven and Danial, came in with a plan and went right two it, peeling off to address varying issues and again, once on the ground it was go time for these guys. Remarkably, all willing and ready to jump in to even the less desirable parts of the project (like who really wants to go into a hot attic and crawl around in the corners? But they did it and with no hesitation or whining). Over all there were several things that impressed me about the Greenlink teams. There is the obvious stuff, like the punctuality and, remarkably, the through cleanup at the end of each day, and also the obvious work ethic, mutual respect amongst the team members and easy and informative communication with me. I think what was the most reassuring though, you could see the obvious pride the Greenlink people take in their work and, just as importantly, the obvious pride they take in working as part of the Greenlink team. That says a lot. I would not hesitate to recommend Greenlink Energy Solutions to anyone. I suspect my neighbors are already tired of hearing about how good they are."
