Freon capacity for heat pump and other ?s

What is the freon capacity of a 3.5 ton heat pump? What is the going rate per pound? What is the feeling for the new Puron vs. 22?

There is no "capacity" of freon for any heatpump or A/C.

There is a design freon charge for each and every heatpump and A/C system.

A heatpump or a/c outdoor unit will come with the correct charge for it, a matched indoor coil and either 15 or 25 feet of interconnecting lineset.

Going rate per pound depends on who you buy it from and where in the country you are.

Doesn't matter what anyone thinks about Puron (R-410A) vs R-22. R-22 is going away, get used to it.

And, Puron is really R-410A, R-410A is Puron. Carrier just calls the R-410A they sell Puron. It's just marketing.

Is 10 lbs of freon reasonable for a 3.5 ton unit? Is $45 per pound a reasonable cost for Florida? I know R-22 is going away but is it a good idea to buy a R-410a unit at a higher cost than a comparable r-22 unit?

410a units will cost a couple of hundred more. $45 per pound is high after the 1st pound. (If every thing after 1st pound is say $20 not bad.) Yes a unit could us ten pounds.

Go to your outdoor unit and read the data plate.

On that plate/sticker it indicates the Factory charge.

That would be the start point of what the charge is.

What would change that is the length of lineset and which manufacturer recommended coil goes with the outdoor unit.
