One thing I like about my job is that I change out old inefficient HVAC systems for new high efficiency equipment with the electric/carbon cost being reduced by 60%. That is no small amount. We can also thank the govt for the new standards. I do no new construction.
Apparently jerm wants me to just tell my customers to not replace their A/C systems. Just another example of how insane he is.
During normal use the new refrigerant r410 never needs replenishing. There is very little leakage. It's too expensive to let go.
I don't know why I'm even bothering to respond to his raving.
