Arrived on site, notes stated to get access to home keys would be in lockbox next to the garage, diagnosed unit and found that furnace was not operational, I finagled furnace and found j was getting voltage in but not sending voltage for unit to operate, I tested blower motor and blower motor worked, circuit board is bad will need to replace circuit board, I also found that unit needs new sediment trap built and installed to bring unit up to code, also unit needs new secondary float switch they have the pan already but they need the switch. Customer approved to have a comfort consultant come out and give him quotes for replacement of furnace.
