Homeowners can come across different issues depending on the type of tankless water heater they have - for gas ones, the burner may get clogged and cause hot spots to burn the heat exchanger. For electric ones, the heating element may need to be replaced if it is acting up.
Ethan did a great job of finding and resolving our leak which required removing drywall, identifying the issue and repairing it in one visit. Very satisfied.
Told me my faucet was broken and I needed a new one. Proceeded to try sell me a faucet and quoted me $800 to replace it. Just take out old faucet and replace it with a new one. That's it....
