@hvacknowitall: A little R290 Leak... Started with a piercing valve to check for a charge, it was empty. Added N2 and found the leak where the cap tube enters the evap. Fixed, pressure tested and evacuated. It was my first time using the @ambrocontrols Precision Torch and also my first time using the @ritchieyellowjacket Hydrocarbon Charging Kit. Unit is running nicely! #hvac #refrigeration #r290 #refrigerationdiagnostic #reachincoolerrepair #refrigerantleak #refrigerationservice #hvacknowledge #hvaceducation #hvaccrvideo #flammablerefrigerant #commercialkitchenrepair
