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.
Mastic sealing, not just tape, for joints that actually need to last.
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 Danville, CA get treated with urgency, not a next-available-Tuesday slot.
