weird heat pump noise

andrelaplume2March 31, 2011

hey guys...I got a year old Trane 14xl...if I recall correctly. I have heard it make the SSSSSSSHHHHHHhhhhhhhh noise now and then this winter...the one that seams to come from outside the house... but tonight and maybe a few times over the last few days I have heard it make a more violent noise with more of a rubbing noise....maybe like turning a rusty spicket off. I've heard it 3 times tonight. The temp outside is 36 degrees, humidity is 86% and its rainy. The weather has been of the type where it feels a little warmer than the degrees would have you believe.

Is this noise normal. Should I have the installers out to check it out? What could it be?

Thank you for reporting this comment. Undo

well, the sssssssssshhhhhhhhhhhh noise is when it exits defrost mode and goes back to regular heating cycle.
Sometimes it can be louder than others when coming out of a long defrost.

If it doesn't always do that I wouldn't worry about that.
