Why does every new window claim to be the magic fix?

Do you think the weep holes actually make much difference in terms of energy efficiency, or are they more about just avoiding water buildup?

I’ve always figured the weep holes are just there to keep rainwater from pooling and rotting things out. Never noticed any impact on the heating bill. Still get that annoying condensation too, especially when the temps swing overnight. Vinyl windows are nice for the no-paint thing, but “zero maintenance” is a bit of a stretch.

Weep holes are primarily for drainage, not energy performance. Keeping them clear helps prevent water from sitting in the frame or sill area, which can lead to damage over time and may eventually contribute to drafts.

For anyone dealing with dirty tracks or exterior openings, clear loose debris gently and avoid sealing or enlarging the holes. A vacuum or a light rinse is usually enough. Cold-morning condensation is more often about indoor humidity and the glass or frame surface temperature than blocked weep holes.
