A quick tutorial of how to perform a decay test. Close off the core removal tool to isolate the system and watch for a rise in pressure. On a small system like this (9k btu) a few minutes should be good. On larger systems you'll want a longer decay. If the pressure spikes and doesn't flatten, it's most likely a leak, if its rises and flattens at 2000 microns for instance, you have some more evacuation to do. This set up had the system down below 500 microns in less than 5 minutes. Tools used in

Valve cores also have a torque spec... The Ritchie YELLOW JACKET RealTorque core Removal Tool fastens to spec. The purpose of the core tool was originally to replace valve cores on live (under pressure) systems. Nowadays, we also use them to pull cores for evacuation and recovery. They are a very handy tool to have around. Most techs carry a few of these. Does anyone else use Refrigeration Technologies Nylog on their cores? #hvac #refrigeration #hvacr #hvactools #hvacsystem #hvacknowledge #hvacl

If you do refrigeration or mini-splits, a valve core removal tool is a must-have. Being able to pull and replace a Schrader core under pressure saves time, protects your gauges, and keeps the system sealed. Small tool — huge impact in the field. ❄️🛠️ #HVAC #Refrigeration #HVACLife #HVACArmy #FieldTech
