Completed furnace, maintenance and inspection. I cleaned flame sensor and wiped down furnace. I checked amp draws and tested components. I tested airflow and temp splits. Airflow pressure is too high on the furnace. Customer is aware of that situation. Furnace is operational at departure. I let customer know about us parting ways with ideal temp. I explained that we would honor the part warranties of the system however, we would not be able to honor the labor warranties since that is directly through the company that puts in the system. I let customer know that today would not be of any cost to them but that we would need to activate the membership in order to cover future maintenance visits.
