      "text": "Check the attic, ceiling cavity, and exterior walls to see where the current exhaust actually leads. The exhaust duct must vent directly outdoors through an exterior wall or roof cap rather than dumping warm, humid air into an attic, floor cavity, or crawlspace.",

      "text": "Confirm whether the existing wiring can support modern units with built-in humidity sensors or delay timers. Choosing a fan with a 10-minute delay-off control helps clear residual moisture after you leave the shower, which requires proper switch and circuit configuration.",

Test the suction with the makeup-air path checked to confirm the room clears moisture smoothly.
