Just had a service call because my tankless water heater stopped working with E110 code. Andrey located the root cause real quick and fixed the issue within half an hour, also gave reasonable recommendations for further maintenance.

The repair person came quickly and was super efficient and polite, and showed me what to do next time. He gave my dog a quick pay and was off again.
