"Very friendly workers, did a great job, and were very careful about any messes they made. The tankless water heater they installed, couldn't have been installed any better."

"Alfonso inspected all of the potential points in the utility room where a gas leak could occur (furnace, water heater, and dryer). He identified the problem with the valve on the dryer and replaced it."

"We purchased a new home a few months ago, and a lot of things needed to be replaced. On the top of the list for us was the furnace and A/C. We called probably 6-7 different companies to come out and give us estimates, but we were never really thrilled with any of those companies, especially after reading reviews. Skip forward a few weeks, and a check valve on our sump pump went out, so water sprayed all over the closet where the sump pump was kept, on a Saturday. Steve made it out in probably 45 minutes or so, if that, and did a fix. The pump itself was old, and the battery backup was not functional, so I decided to have the whole thing replaced. A few days later, the job was done. I was impressed by Steve, and saw that they did HVAC work, so I decided to have them do an estimate on a new A/C and Furnace. Later the same day, the owner of the company came out and gave us an estimate. There was no pressure whatsoever to make a purchase, the conversation was just matter of fact about what we needed and what we didn't need. We live in a town that technically requires permits to do work like this, but every provider up until TopTec said that we could get away without doing the permits, so why pay the money. TopTec encouraged us to do the permits so we'd have a third party review their work to ensure it was done right for our own peace of mind. This really told me that not only they were confident in their work, but also that what was going to be done would be up to code. I had been toying with getting a new hot water heater based on how old ours was, so we decided to have them do that too. The workers were thoughtful and explained everything in detail. They don't subcontract. If you are looking for the absolute cheapest provider, these guys probably aren't for you. But, if you want the job done right, thoroughly, and with high end products, this guys are the route you want to go. It's so hard to find providers you can trust, but I really feel like they earn the high review scores they got if you do your research. I'll definitely have more work for them in the future."

"On November 15th Chicago was hit with some extreme wind gusts that caused my water heater pilot light to extinguish. I thought this was a simple reset, but the problem was more complicated. I learned the electrode was defective. Had I undertaken this project as a DIY, I would have spent more time than I would have cared to try to figure out why I could not get a flame for my water heater. I was smart to call Four Seasons. My technician figured out the problem quickly. There are times when calling a professional makes sense. I am not an expert on water heaters outside of knowing how to turn it on, clean it periodically, and knowing when I need a new one. Thank you Four Seasons for responding quickly and bringing me hot water."

"Carlos is excellent. He is very responsive, professional & reasonably priced. He & Eli installed a new water heater very quickly for us after our old one started leaking. I highly recommend CAB Backflow and would absolutely use them again for other plumbing jobs."

"We are new homeowners and had a hole in our septic tank made of concrete block, which was sending wastewater into the foundation/basement of the home. It was my first time using Angie's List, and I would recommend Illinois Sewer and Drain to anyone. Joe and his team of experts solved our issue immediately at an affordable price. They even went above and beyond to install a sump pump in our basement to help with the rain water. Quality work!!"
