A surprising share of a home's conditioned air never reaches the vents at all — it escapes through leaky duct joints in the attic or crawlspace.
Insulation and airflow balancing are addressed together, not treated as separate problems.
If you're dealing with one room that never quite reaches temperature, unusually high utility bills relative to system size, or visible disconnected duct runs discovered in the attic, you already know leaky or poorly balanced ductwork can waste a significant share of a system's output before it ever reaches a single vent, and most homeowners never know to check.

Most ductwork repair problems give some warning before they turn into one room that never quite reaches temperature, unusually high utility bills relative to system size, or visible disconnected duct runs discovered in the attic — catching it early usually means a shorter, cheaper fix.
