Check out a GSHP.
Years ago I read that the push to replace R22 was by Dupont because their patent was expiring.
"A thousand EPA employees' throats may be cut in one night, by a running man."
And of course, these periodic checkups are not free, but substantially raise the operating costs that the EPA did not care to figure in when they required the manufacturer to calculate costs for purposes of that informative performance notice they must attach to every unit.
Moreover, there is no accounting in this for the environmental burden of having a service technician drive his truck to every customer’s house twice a year for this. Over the life-cycle of the equipment all these issue add up in oh so many ways.
Yet another way the enviro-libs are saving the planet using bureaucrats with guns.
Freon was the best coolant for this purpose ever invented.
But the company patents were going to run out, and it was worth $trillions
So... with the aid of enviro-weenies they get their own product banned, and introduce a new product that is many times worse
And discover the power of enviro-weenies in controlling the government
But you and I do.
r410-a is known to damage the seals and create leaks.
The entire freon/ozone layer issue is a hoax.
Had ENOUGH Yet ?
