bought another home and it already had a brand new (Gibson) heat pump and air handler installed
H/P Model #: JT4BE-030K
AIR HANDLER Model #: B6EMMX30K-B
Over the last couple weeks, later in the evening around 10pm or 11pm, when it was colder, guess around 30 degrees or so, I've heard this loud moaning sound coming from the vicinity of the heat pump. The sound lasted about 10 seconds or so. Last week it was really loud and felt like it vibrated the floor.
The line set does run beneith the floor where I thought I felt the vibration and after viewing the lineset, its about an inch or so away from floor joist and subflooring.
Tried googleing the symptom and seems like there could be somthing going on with line pressure and reversing valve. and possible sticking of reversing valve. Dont really understand all the stuff I've read.....
I realize that this is hard to diagnose, since you arent here to witness this "MOANING" sound. Its happened several times over the last 3 weeks or so and has only happened when it COLD outside.
Hope this is enough information for you.
Thank you all for your time. I do appreciate your assistance.
