"Reasonable price"

"My mother contacted Four Seasons Heating and Cooling on 01/26/2026 for a water leak. What should have been a simple service call turned into them replacing her boiler?something that was not needed. The technician arrived at 8:00 a.m. and instead of shutting the water off, allowed it to continue leaking for approximately three hours while he tried to determine ?how my mother?s credit was? so they could charge her for additional work. He even made the comment, ?Oh, there is no way you could afford this in cash,? which was extremely inappropriate and unprofessional. After being pressured into purchasing a new boiler costing nearly $17,000, her tenants were left with NO HEAT because the job was not completed correctly. A second technician had to come out to bleed the old pipes and stated that the original work was done incorrectly. I was on the phone during a call with customer service and had to take over because of how rude and disrespectful they were toward my mother. Once I took over"

"I had my air ducts cleaned by TopTec and couldn’t be more impressed. Mostapha and Jesus were the technicians, and they were both fantastic — super professional, friendly, and incredibly thorough. They took the time to explain the process, answered all my questions, and treated my home with care and respect. The results speak for themselves. If you're considering duct cleaning, don’t look any further. TopTec is the real deal!"

"Flawless execution! Professional crew of well-trained people! For not that much more than someone quoted to mill my pipes, Illinois Sewer replaced my bad pipes then installed a pipe in pipe liner. I couldn’t be happier. These men are number!!!!"

"Danny D, Jerry, and Adam, y’all are stuck with me as a client lol. They provided excellent service, funny, kind, accommodating and explained all that they were doing and all of our goals in maintaining my plumbing. They went above and beyond and I know in the future this is my go to team for our plumbing needs. They showed up last year and this year and just taught me so much in maintaining my home system and their expertise!!!"
