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.
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, which is exactly why ductwork repair calls in La Mesa, CA get treated with urgency, not a next-available-Tuesday slot.

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.

They showed me actual before-and-after pressure readings instead of just saying 'it's better now'.
Return duct was undersized the whole time, apparently common in homes our age.

A pressure test gives a definitive answer rather than guessing from symptoms alone.
