"Lifeline was great. Our hot water heater went out tonight and within 1.5 hours of calling Brandon was here ready to replace our hot water heater. He gave us multiple options and discussed each in detail with us. Very professional and will definitely use again."

"They were able to assess the job with a couple of photos to recognize the old power-vent heater I had and what a replacement would cost. We discussed options, and they could upgrade me to a tankless heater for a relatively small increase. Was in and out fairly quickly and we were very satisfied with the new tankless."

"Initial estimate was scheduled with no problem, they took the time to answer all the questions I had about the furnace replacement. I received estimated from 6 other HVAC companies and American Family was basically the lowest, but I also felt comfortable with the level of knowledge and experience that was conveyed at the estimate. I scheduled the install and was a bit disappointed that the installers did not show until 10 am or so, but that was not a big problem as I had assumed the job would take all day. The job took longer than expected (past 7pm) and the installer wound up having to replace an entire part of the intake duct work that he did not expect to, but in the end the unit and ductwork looked clean and sturdy and well intalled. The owner called for a follow up appointment and he came in to look at the install and make sure all the settings were correct on the furnace. He answered any questions I had at that time. All in all a good experience with a good company"

"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."
