Barron performed scheduled maintenance ($365) on my Navien tankless water heater, which they had originally installed. The water heater seemed to work well immediately after the technician left and then, the next time I needed hot water it turned itself off and would not come back on. I had to call their emergency tech who did not arrive until 11 PM. This is typical of Barron service. The techs are friendly and courteous, but one of their service calls is usually followed by another service call to fix what the first tech screwed up. I'll be looking elsewhere for any further service needs. And do yourself a favor: don't ever buy a Navien tankless heater. They are disappointing, expensive pieces of junk.
