I think it was Paranormal Home Inspectors

I’m not sure if it’s quite what they were talking about, but the first season or two of the original Ghost Hunters was a lot like this. They would at least pay lip service to try and disprove the ghost, and I believe they even left a location and straight up told the owner that it probably wasn’t haunted, just old

It’d be funny if they said the ghosts were loosening the doors and messing with the plumbing
