What would cause a Heat Pump to make a brief whistling noise when it is not running....refrigerant pressure equalizing?

That is what I always thought. It should only do that shortly after turning off though.

It works fine, but I noticed it making the noise again tonight and thought someone might have a guess. Equalizing is what my guess is.....but I could be wrong.
