"Tankless water heater went on the fritz last Monday. Submitted HomeAdvisor request for quote and Rob called almost immediately. Took some pictures of the old unit and plumbing and had an all in reasonable estimate. They came out next morning (to the city no less) and installed new unit in a few hours, explained everything and tested and was within estimate. Very knowledgeable and professional. Have great hot water on demand. Wife is very happy as our old Eternal tankless struggled ever since we moved in 3 years ago. Very happy with the recommended Navien and installation from RA."

"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."

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"Service guy came as scheduled. Sent his "service" requirements to home base Home base calls back and lists, a very long list of what needs to be done and a very long list of what is not covered and what each item costs. The overall cost was outrageous and they weren't willing to give it to me in writing. Everything I had to pay for was overpriced, of course! They told me my other option would be to purchase my own water heater and they would reimburse me for what there water heater would cost, but no reimbursement for Labor, building permit, or any upgrades required by the local building department. The requirements of the building department were minimal. I went to Home Depot and had them do the installation and saved many hundreds of dollars. Lesson learned, have AHS do simpler repairs that don't require municipal building department approval. Have AHS pay for the equipment, and purchase installation from a trusted local installer."
