During the cooler months of the year when I am using my heat pump, rather than my pellet stove, I hear it occasionally go into a defrost cycle. The fan in the outside unit will be stopped and I can hear the compressor humming away. I've been told it is pump hot gas back into the outside coils to eliminate any frost or condensation build up..
Now for my question: Several times a week I drive by a million dollar home on the shore of Hood Canal. There is a AC/Heat Pump unit plainly visiable.. Well not exactly visiable during the winter since it is always totally encased in gigantic ball of frost and ice. Really, it about 6 ft in diameter. If I ever saw someone outside (and I thought I knew what I was talking about) I would stop and suggest that they call the service man to adjust the cycle control settings.
Tell me if I'm wrong, but I don't think a unit in this condition could be operating anywhere near efficiently??
I know we have several AC people hanging out here.. Comments please??
