The bare minimum basic repairs to get the system running today. Came out for a no heat. Customer stated she had a different electrician wire up her thermostat to the unit. Thermostat system was completely wired wrong. Rewired thermostat and also all the wires at the furnace control board plugged in the flood safeties and the outdoor unit. Turn the system on the thermostat. System is now heating properly. Also found that the flue pipe is in Porsche has lots of tape and some sagging recommend re-running with new pipe. Also found that the filter door is not there on the system. Cardboard is being used and the correct filter is not in there would recommend Getting a new media filter rack to ensure that the filter is acting as it should system is now heating properly on departure.
