Hey folks, new to the site. I had my a/c unit replaced under a home warranty when I bought my house years ago and the original Carrier unit (a/c only) was replaced with a Goodman split system heat pump unit. It's never been wired to use for heat, just for a/c, and every time the outdoor unit shuts off after a cooling cycle there is a loud "whoosh" as the reversing valve is de-energized. Is that normal? I'm including a link to a mp3 I just made of it shutting off. Thanks!
