Is it really necessary to inspect your exposed ductwork for leaks and loose joints?

It's recommended but situational: worth doing for many homes, though skipping it won't usually cause damage on its own.

How often should you inspect your exposed ductwork for leaks and loose joints?

Quick answer: Once a year. Ducts running through an attic or crawlspace dump conditioned air where nobody lives, and pull dust and humidity back into the house.

Why it matters

Upkeep & performance

These tasks are more about efficiency, longevity, and comfort. Not a huge deal if you miss one, but it pays off over time.

Staying on schedule matters beyond the repair bill: a consistent maintenance record is one of the factors in a home's Roots Home Health Score, and well-kept homes typically sell faster and closer to asking price.
