Replace burners and inducer coupling. -Coupling is back ordered so we will replace it when we do the AC maintenance or sooner. !
Installed tiger loop
No heat oil furnace. I found that the oil was not being pumped out. I had no oil pressure. I bleed the lines and the pump was still producing no pressure. I purged the oil lines with a vacuum hand oil pump and then replaced the oil pump. I put a new tank filter on as well. I checked combustion and setup oil pressure. Thank you!
The maintenance on your York warm air propane furnace went well. We recommend replacing the coupling in the furnace. It is worn. The heat issue you are experiencing is likely caused by the burners corroding. Sometimes it will burn off in the beginning of the season. We will send a price over to replace the burners. We replaced the air filter today. Thank you!
