I'm using a newer Mitsubishi heat pump/AC. It supplements about 75% of my heat
load. I only run it in 20°+ ambient temps as I was told that at today's fuel
prices the cost rotation is at 17°.
I love it. My fuel oil usage last year dropped about 50%, about 10% increase
in electric bill. If
So every day the tide comes in and goes out the marsh 2 times, I should
dig a hole and let it fill up with new warm water and run a loop through
that! I would probably run afoul of 37 EPA regs and wetland regs and
who knows what else, but I would be saving energy and using renewable
energy!

Well, every so often its supposed to automatically kick on in ac mode
to defrost the outside unit. When it does so, you will see a big cloud
of steam come off it for a minute. Sounds like yours is not doing that.
At my old place we had 2 units, one winter one of the units froze in a

its more expensive.

Thanks all for the ideas. I did cycle the AC on for about 10-15 min,
then left it sit for about 1/2 hour while I had lunch and it melted down
the coils. I just turned it back on to see if it works.
There is an aux light on the thermostat, maybe that is the extra
resistance heat coming on?
yea, if the aux light is on that is the electric heat coils, at least
they are supposed to be running. The other thermostat thing might be
the humidity control. I think ours had that but I dont know if it
worked or not.

When mine did that it was low on freon. A re-fill cured it for a
couple of years. By then the leak had gotten too bad to continue to
re-fill, so we replaced it with a new unit.

The efficiency is linked to how far uphill it has to shove the heat.
If it's pulling heat from 50 degree air, it's probably about 3x efficient.
