Loss of Freon When Checking Subcooling Superheat ??
When a technician is testing the charge level or subcooling or superheat, and is using gauges with hoses that are several feet long, how much Freon is lost from filling up the hoses? Should the technician have a canister of Freon with him to replace what is lost when he completes his system check? Thanks.
