Your air conditioner can be perfect and the house still won't cool if the ducts are failing. In Fort Lauderdale's attics — 130 degrees plus in August — leaky, crushed, or disconnected ducts dump expensive cold air where nobody lives.
We inspect, repair, seal, and replace residential ductwork across Broward County. Every replacement quote includes a duct evaluation, because new equipment on bad ducts is a wasted investment.
What Failing Ducts Look Like
Some rooms never get comfortable while others freeze. The system runs constantly. The electric bill climbs. In the attic: flex duct crushed by storage boxes, runs disconnected at the plenum, insulation torn or missing, and joints that were never sealed — just taped, decades ago, with tape that's long since failed.
Mid-century ranch homes across Oakland Park, Plantation, and inland Fort Lauderdale often still run their original ducts. Decades of attic heat destroy flex duct from the inside.
Repair, Seal, or Replace
Not every duct system needs replacement. Disconnected runs get reconnected and sealed. Damaged sections get replaced. Leaky joints get sealed with mastic — not tape — which is the permanent fix.
Full replacement makes sense when the ducts are broadly deteriorated, undersized for the system, or designed wrong from the start. We show you what we find in the attic — photos, not adjectives — and quote the right scope.
Design Matters as Much as Condition
Even intact ducts can be wrong: undersized trunks that starve distant rooms, missing returns that leave bedrooms pressurized, and supply registers placed where furniture blocks them. When we redesign, we size the trunk and branches to the system and the rooms, place returns where air actually needs to move, and balance the airflow room by room.
Ducts and Indoor Air
Leaky return ducts pull hot, dusty attic air straight into the system — and into your lungs. Sealing the ducts doesn't just cut the electric bill; it cuts the dust, the humidity, and the attic air infiltrating the house. If indoor air quality is the concern, the ducts are the first place we look — see indoor air quality and duct cleaning.
Common questions
How do I know if my ducts are the problem?
Uneven room temperatures, high bills despite a healthy system, and visible attic damage are the tells. We inspect and measure airflow — the data decides, not a guess.
Can ducts be cleaned instead of replaced?
Different jobs. Cleaning removes dust and debris from sound ducts; it doesn't fix leaks, crushed runs, or missing insulation. We tell you which one you actually need.
How long does duct replacement take?
Most single-family homes take one to three days depending on size and access. You'll have the timeline and price in writing first.
Will new ducts lower my electric bill?
If the old ducts were leaking significantly — and many are — yes. Sealed, properly sized ducts can cut cooling waste dramatically.
