Mega Thankyou's to Xringer, BradC & jeff5may!

You've provided some interesting info & approaches. The manual looks awfully close to the unit I have. The differences appear to be very small.

Geo NR Gee: Nope, the coils are sparkling clean... much cleaner than the fan blades.

At this point, I don't have any intention to run the unit in cooling mode, but for the time being, I'll leave the reversing valve where it is. It might be useful to be able to send some of the summer heat into the ground.

Anyway, from your info, I'll do some testing & let you know what I'm finding out.

BTW, I saw a time-line chart the other day about R22, and it looks like the final phaseout (no more sales of R22) will be a few years from now. So you can expect to see a considerable amount of good HVAC hardware for a song or even free, pretty soon. I was seeing new R22 mini-splits for sale as recently as 3 years ago... in a few years, they'll be unserviceable unless you know a few secrets.

Keep your eyes peeled!

Best,
