Heat pumps with R410A refrigerant
prices on 1 modelR410A
— like R407C, this freon is ozone-safe but it requires even higher operating pressures (and, accordingly, reliable and expensive equipment), and it is not cheap. On the other hand, R410A components have the same boiling point, and in the event of a leak, it is not necessary to change the refrigerant completely, just replenish it.
