co2 usage, bad good or gr8?

I’ve been using co2 this past summer instead of nitrogen, many benefits!

1-it lasts 3-5 longer then nitrogen

2- less going to supply house. less time wasted…

3-I find no issues as far as vacuuming after its pressurized

4-its 99% co2

 

issue:

When I feel the pressures decrease in large cavities like a compressor, however not so with lineset.

 

what is your opinion?
