Customer is in North Carolina and has tenant in the unit for three months out of the year. Tenant says hot water heater continues to trip the breaker. Heater installed is an N-120 Titan tankless. Heater has a safety shutoff switch. Customer thinks the issue is in the heater itself. I recommended that we replace the switch and the heater. He told me that he doesn’t need to replace the switch. I gave him a price for the heater alone and the gentlemen told me that he paid 250 to replace the heater two times prior from John the Plumber. I explained to him that prices have changed and he said that he thinks that he won’t be able to do that price. He said a plumber came out last time and only took 20 mins to replace. I explained we do not charge by the hour. We charge for the efficiency, quickness, knowledge, and professionalism you get with John the plumber. customer said he will talk to his partner but he most likely will not do it.
