Arrived on the job site, and the customer reported that rodents in the attic had chewed through the air-handler wiring. We will return tomorrow morning to run a new line through the existing PVC-protected junction box on the eave and extend the wiring to the air handler. We will also be replacing a couple of customer-supplied breakers. The customer is fully satisfied with today's visit and understands that there is a five-year warranty on the junction box, all connections, and the new wiring to the furnace. The customer also understands that the breaker connections are covered for five years, but the breakers themselves are not.
