Block one return and suddenly the blower’s working harder, coil temps shift, and the homeowner thinks the system is failing. Then you’re the bad guy until you show them what’s actually happening.

You don’t see it until you open things up and start tracing paths. From the outside it looks normal, but inside it’s fighting itself.
