We get a lot of questions about both evacuation procedure and TXVs so last week we produced videos on both topics, including: • Before and after testing of piston vs. TXV • Using the Bluvac Measurequick app • Use of core remover tools for evacuation • Flowing nitrogen • creating an external equalizer port and […]

There are many appliances with compression refrigeration circuits that do not have ports installed for testing, recovery, charging, and evacuation. Â These can include window units, PTACs, fountains, refrigerators, and much more. This fact presents a challenge any time you suspect or know there is a refrigerant circuit issue. How can you diagnose and repair when […]

Great vacuum quiz! Really good summary of important concepts. While I missed 3, I understand and agree why I did on 2 of them, but do not understand the following question. Why is “Register No Vacuum” wrong and “Register Vacuum” correct? I’ve used Fieldpiece and Supco and, when slight refrigerant pressure is applied to break vacumm, the vac gauge display of the system micron level is lost and shows Atmospheric. Thanks.
1. Exposing a typical vacuum gauge to refrigerant vapor will make the gauge?
Fail

Register No Vacuum (my answer)
Register Vacuum (quiz correct answer)

I run my vacuum to 150-200 microns if it fluctuates up and down during pull down moisture it it didn’t drop below 300 leaks then you have your trapped refrigerant in oil time

How can #3 be all the above when all the answers are below?
Did poorly on the test but I don’t work in the trade, I have an AS degree in HVAC, 608 Type 1 & 2 certified, but circumstances out of my control lead me down another path . I came across your podcast a week ago and can’t thank you enough for the info you are putting out. You are doing a great service and great job!
