"I received a lower price than the other two brands we got bids from and the installation was well done. I did not want to buy a water softener online and install it myself as I knew some plumbing would have to be done so I was willing to pay more to have an experienced person perform the installation."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Great crew and awesome service. I had a hard time finding a place interested in dismantling a rusty failed 10k steel water holding tank. These guys got it done quickly, cleanly and they were very nice and good about communication. Top notch!"

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"
