Jack,

The Whoosh is the reversing valve of the heat pump changing from
cooling position to heating position & is normal. The squeak is most
likely the outdoor (condensor) fan motor. It could be a cabinet
squeak, but not likely. I have never heard a hermetic (Tin Can)
compressor make that kind of noise (Squeak). Try oiling the outdoor
motor if it has ports. Use 20 or 30 grade non-detergent motor oil. If
you use detergent motor oil, eventually the oil evaporates, leaving the
detergent to lubricate the motor, which it won't. But of course that
will take several years.

The blower motor refers to the motor that moves air through the ducts.

Hope this helps

It is now squealing almost constantly and intermittently "whooshing".
The whooshing is no longer present only when I turn it off.
Question---If the squealing is associated with reduced rpm's of the
condenser fan, could that reduction bring about the whooshing? It still
appears to cool just fine, but is very noisy, and would wake up the
neighborhood if I had it on at night. I'll probably just have the fan
replaced and see if that fixes it, but am I risking further damage if I
continue to run it this way until I can have the job done?
