    Mysterious Gurgling in Wall

    Hello everyone! New member here... I moved into a new-construction house about 6 months ago, and for the past 4 weeks I have been periodically hearing a strange gurgling sound in our wall. I only began to hear it after using a rarely-used bathroom. I initially thought it was a plumbing/water issue, so I had a plumber come check it out. He informed me that there are no water pipes where the sound is coming from - very strange. I've since tried researching this issue online, but I haven't found much to go on. I feel like it has to be related to me using the sink, toilet and shower that rarely gets used, but after speaking to the plumber part of me thinks it might somehow be a furnace/HVAC issue... If anybody has any suggestions or thoughts I would greatly appreciate them. Thanks!

    Do you have linesets or a condensate drain/piping in that wall?
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    I do have some type of piping in that wall, I believe for the HVAC system. But i'm not sure what kind

    I doubt it will be possible to diagnose this problem without knowing what is even inside the wall.

    A lot of times they connect a/c drains to the sink or tub. In heat mode the trap will be dry/partially dry depending on heat source allowing air to pass thru and sometimes making noise. Nothing to be concerned with other than the sound.

    Thanks for the responses everyone! I'm going to share some of these thoughts with a plumber and/or HVAC tech and see what I can figure out from there
