Safety pan
A safety pan is a tray placed under equipment like an air handler to catch leaks and overflow.
Why it matters
It provides a backup layer so a small leak does not become ceiling damage.
Where people get this wrong
A pan without a drain or float switch is only partial protection. Pans are most important when equipment sits above finished space.
Real-world example
An attic air handler develops a slow drip. The pan catches it and the float switch shuts the unit down before water hits drywall.
Where this hits your build
This affects daily comfort in every room. Problems often show up after move-in when certain rooms run hot, cold, or noisy.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
