I have, thank you for asking and replying! But apparently not 2x per
year to drain and clean the coils as they tech I just got said you're
supposed to do. I had no idea! I've had like every other year PM and no
one told me 2x per year.

CY: A good tech with experience in heat pumps can catch a lot of
problems while they are small.

So is this how to save the coils? 2x per year
draining and cleaning?

CY: In theory, the water that collects on the coils
should run down into the pan and then down the drain,
by gravity. Some times, things don't work as well.
The coil might shift and be sloped the wrong way.
Algae and dust builds up, and drains clog. A skilled
tech would catch this kind of problem early.

Does this mean draining the coolant, whatever
replaced freon? Preon or whatever he told me is used now?

CY: Unless you're doing major repairs like replacing
a coil, you generally don't need to remove the
refrigerant. The name Puron is a brand name for one
brand of R410a. Just like Freon is one brand of
refrigerants, which might include Freon 12, Freon 22,
Freon 500, Freon 502.
