Duct installation · Aventura, FL

A bigger unit rarely fixes it. The route of the duct usually does.

Undersized duct chokes the system, oversized duct lets the air lose speed, and a branch with four bends to the far bedroom will not cool it whatever equipment feeds it.

Size and route decide it

Someone picked the size of your ducts once.

Few owners are ever told that ductwork has a size: a width, a length and a count of bends, chosen once for the home as it was built. What follows is what happens when that choice was wrong, and a larger air conditioner fixes none of it.

  • Too narrow: the blower struggles

    The fan can only push through the duct it has. A run too small for its air load raises the resistance, so the equipment spends its years working against the home instead of cooling it.

  • Too wide: the air loses speed

    Spread across more duct than it needs, air slows down. It reaches the grille without push, drifts along the ceiling and never gets to the far side of the room.

  • Each bend takes a toll

    A branch that bends four times on its way to a back bedroom loses pressure at every turn. However big the outdoor unit, that room stays warm because the air never gets there.

  • A layout by accident

    Most ductwork takes whatever route was quickest for the original builder, then gets extended for a remodelled kitchen or an extra bathroom. Replacement is the one chance to route it on purpose.

  • Flex drifts from where it was hung

    Flexible duct is a plastic sleeve on a wire coil. Above a ceiling it sags between straps, kinks at bends and flattens against framing, and every sag restricts air from that day on.

  • More tonnage, same weak grille

    Forcing more air down the same small run adds pressure and noise and leaves the same feeble breeze at the register. The duct, not the unit, sets what each room gets.

How we decide

Five decisions made before any cut.

Open each decision. New ductwork is mostly choices about path and size; the cutting is the easy part, and it happens last.

  1. Inspect before replacingThe cheaper fix is often right.
  2. Measure the home, not the old ductThe existing run is a clue, not a plan.
  3. Route first, then sizeLength and bends matter more than you think.
  4. Quote at your home, before workWe price after looking, never before.
  5. Install, then walk it throughYou see the result before we go.

Decision 1 of 5

Inspect before replacing

A warm room alone does not justify new duct. Dust along a run, a torn collar joint, a sagging length, a stuck damper all cause the same complaint and cost less. A reviewer on our Aventura listing describes second-floor bedroom temperature spikes that went back to normal once the problem was fixed.

Decision 2 of 5

Measure the home, not the old duct

How many rooms need air, how far each is, where the air handler stands, what the ceiling space or framing will allow. The old duct shows what someone once did, not what the home needs; copying it just rebuilds a poor layout in new material.

Decision 3 of 5

Route first, then size

A short straight branch and a long one with four elbows are not equal at the same width. So we fix the route first (trunk, branches, return locations) and size each piece from there. This decision is what makes the end bedroom comfortable or not.

Decision 4 of 5

Quote at your home, before work

Cost depends on the size of the home, how much duct is replaced and what the space allows, so the figure comes on site after a technician has seen it, before anything starts, with no obligation to book that day. A reviewer on our Aventura listing says the price was exactly what was quoted, with no hidden fees.

Decision 5 of 5

Install, then walk it through

The old duct comes out, the new goes in, boots and grilles are refitted, and an adult over eighteen goes over it with the technician: what was replaced, what stayed, and anything worth knowing found along the way. We sweep and put furniture back before leaving.

Where we install

New duct in seven places, from towers to 1950s houses.

The space available for duct changes with each place and each decade, and so does the layout we find behind the ceiling. Every place has its own page with its Census housing figures.

    Noticeably stronger breeze coming through the upstairs registers following the air vent clean.

    Never knew dryer exhaust lines could hold so much lint, really pleased we had them complete a dry vent clean.

    When they helped solve the problem, the temperature spikes in the bedrooms on the second level went back to normal.

Common questions

What people ask about replacing ductwork.

Send us a question
How can I tell if my ducts need replacing rather than cleaning?
Usually you cannot, which is the point of the visit. Dust along a run, a torn collar joint, a sagging length and a stuck damper produce the same complaint, and each is cheaper to fix than replacing. Replacement is right when the run itself has failed: crushed, split along its length, or laid out so poorly that no cleaning will get air to the room at its end. We look first and tell you which you have.
What does a wrongly sized duct actually mean?
Every duct has a width, and the air the fan produces must pass through it. Too narrow and resistance rises: the equipment runs longer, moves less air and wears sooner. Too wide and the air spreads and slows, arriving at the grille without push and never crossing the room. From the sofa both feel the same: weak air. A bigger unit fixes neither, because the duct sets what each room receives.
I was told I need a larger AC unit. Is that true?
Sometimes. But a bigger unit on the same undersized duct is a noisier version of the same problem, so check the ductwork before anyone quotes new equipment. A reviewer on our Aventura listing describes second-floor bedroom temperature spikes that returned to normal once the problem was solved. We would rather tell you that than sell a system you do not need.
Are there reviews of your duct replacement jobs?
Not specifically, and it is fair to say so. The reviews on our Aventura listing describe cleanings and repairs: an open crack in attic ducting fixed permanently, a disconnected joint behind a finished wall found with a camera, a rusty corner seam on the main intake box welded with galvanised sheet metal, new hardware on a broken damper handle. Those are the closest to this work. Every review is on the listing itself, which our reviews page links to.
Will new ductwork make my home cooler?
It will not enlarge the system, and nobody should promise you a number. What it changes is how much of the cooling you already produce actually arrives: less resistance for the fan, air that still has speed at the grille, and a far room on a branch short enough to serve it. If one room has never worked while the rest are fine, the duct is usually to blame rather than capacity.
How much does new ductwork cost?
It depends on how much duct is replaced, how many rooms it serves, what the space allows and the material, so no fair figure can be printed here. You get the number at your home after a technician has looked and before anything starts, with no obligation to book that day.
Where do you install ductwork?
In Aventura and its Miami-Dade neighbours Golden Beach, Sunny Isles Beach, North Miami Beach and Ojus, and over the line in Broward, Hallandale Beach and Hollywood. Each has its own page in the service-area guide, built on the housing figures behind what we usually find.
