Looking down the inside of a rectangular duct run, its walls rust-stained, the passage receding into darkness

Duct installation — Jupiter, FL

The tonnage is not the problem. The path the air takes is.

Duct that is too small starves the system. Duct that is too big lets the air slow down before it arrives. And a run that takes four turns to reach a far bedroom will never cool it, whatever size unit you put in front of it.

Why sizing decides it

Your ducts have a size, and somebody chose it.

Most homeowners have never been told their ductwork has a size at all. It does: a width, a length and a number of turns, picked once for the house as it stood then. Everything below is what happens when that choice was wrong, and none of it is fixed by a bigger air conditioner.

  • Too small, and the system starves

    A blower can only push air down the duct it is given. A run narrower than the air it must carry raises the pressure the system works against, so the unit spends its life fighting the house rather than cooling it.

  • Too big, and the air slows down

    Air spread across a duct wider than it needs loses its speed. It arrives at the register with nothing behind it, drifts along the ceiling, and never reaches the far side of the room you are standing in.

  • Every turn costs you something

    A run that leaves the plenum and takes four turns to reach a back bedroom has given up pressure at each one. That room will not cool whatever tonnage sits outside, because the air is not getting there.

  • A layout nobody actually chose

    Most duct follows whatever path was quickest for whoever built the house, then gets extended for a garage conversion or a new bathroom. Replacing it is the one moment it can be routed deliberately.

  • Flex duct does not stay where it was put

    Flexible duct is a plastic sleeve over a wire spiral, and in an attic it sags between straps, kinks at a turn and crushes against a joist. A sag is a restriction from the day it happens.

  • A bigger unit makes it worse, not better

    More air pushed down the same undersized run means more pressure, more noise, and the same disappointing draught at the register. The duct decides what the house actually receives.

The two materials

What a run is actually made of.

Replacing ductwork means choosing what the new run is built from, and the two answers look nothing like each other from the inside. Flexible duct is quick to install and forgiving of a crooked path. Rigid metal holds its shape, its size and its direction, and has to be made to fit.

How the job is decided

Five decisions, before anything is cut.

Tap any step. Replacing ductwork is mostly a sequence of decisions about size and path — the cutting is the easy part, and it comes last.

  1. We look before anyone says replaceThe cheapest answer is very often the right one.
  2. The house is measured, not the old ductWhat is there is evidence, not a specification.
  3. The path is chosen before the size isLength and turns cost more than most people expect.
  4. The estimate, in your home, before any workPriced after we have looked, never before.
  5. The work, then the walk-throughYou see the result before we pack up.

Step 1 of 5

We look before anyone says replace

A room that never cools is not by itself a case for new ductwork. Buildup along the run, a torn joint at a collar, a length that has sagged in the attic, a damper that has stopped moving — all produce the same complaint, and all are cheaper. One review on the profile describes exactly that: the ductwork was checked before anyone discussed a new system, and the house did not need one.

Step 2 of 5

The house is measured, not the old duct

How many rooms the system has to reach, how far each one is, where the air handler sits, and what the attic framing allows. The duct already in the ceiling tells us what somebody did once; it does not tell us what the house needs. Copying it is how a bad layout gets rebuilt in new material and disappoints its owner a second time.

Step 3 of 5

The path is chosen before the size is

A short straight run and a long one with four elbows are not the same duct at the same width. So the route is settled first — where the trunk goes, which rooms branch off it, where the returns sit — and the sizes follow from it. This is the step that decides whether the bedroom at the end of the house is ever comfortable.

Step 4 of 5

The estimate, in your home, before any work

Cost depends on the size of the house, how much of the run is being replaced and what the attic allows, so the figure is given on site once a technician has seen it, and before anything starts, with no obligation to book on the day. Reviewers on the profile mention the price at the end matching the price at the start.

Step 5 of 5

The work, then the walk-through

The old run comes out and the new one goes in, the boots and registers are refitted, and then someone over eighteen walks the result with the technician: what was replaced, what was left, and anything found on the way that is worth knowing about. The floor is swept and the furniture goes back where it was before we leave.

“At first, we thought that the problem with airflow upstairs meant we needed a whole new HVAC system”

“At first, we thought that the problem with airflow upstairs meant we needed a whole new HVAC system. Luckily, the expert checked the ductwork first and found that years of buildup inside the vents had made it hard for air to flow. After fixing and cleaning the damaged areas, the whole floor is finally cool again. Saved us from wasting thousands of dollars.”

Taylor Warren
“Finally, the heat is the same in every room”

“Air conditioning was blowing straight into the unfinished attic because of torn foil tape around the main plenum collar. Using heavy-duty glue to seal the gap fixed the problem right away and got the rest of the house back to normal static pressure. Finally, the heat is the same in every room.”

Ask us directly
How do I know whether my ducts need replacing or just cleaning?
Usually you do not, and that is what the visit is for. Buildup along the run, a torn joint at a collar, a length that has sagged in the attic and a damper that has stopped moving all produce the same complaint, and every one of them is cheaper to put right than a replacement. Replacing is the answer when the run itself is the problem: crushed, torn along its length, or laid out so badly that no amount of cleaning will get air to the room at the end of it. We look first and tell you which one you have.
What does it mean for a duct to be the wrong size?
Duct has a width, and the air the blower makes has to fit through it. Too narrow and the pressure the system works against goes up: the unit runs longer, moves less air and wears faster. Too wide and the air spreads out and slows down, so it reaches the register with nothing behind it and never crosses the room. Both feel identical from the sofa — weak air — and neither is fixed by a bigger air conditioner, because the duct decides what the house actually receives.
My air conditioning company says I need a bigger unit. Do I?
Sometimes. But a bigger unit pushed down the same undersized run is a louder version of the same complaint, so the ductwork is worth looking at before anyone quotes a system. One review on this profile describes a homeowner who was sure the airflow upstairs meant a whole new system was needed; the ductwork turned out to be the problem, and the floor cooled properly once it was dealt with. We would rather tell you that than sell you a replacement you do not need.
Do you have reviews from duct replacement jobs?
Not specifically, and it is worth saying so plainly. The reviews on the Jupiter Google profile describe cleaning visits and repairs: a sagging flexible run re-hung with new strapping, torn foil tape at a plenum collar sealed, a boot re-anchored to the studs in the wall, ductwork in a crawlspace checked at no extra charge. Those are the ones nearest this work, and those are the ones quoted on this page. Every review on the profile is on our reviews page, the one-star included.
Will new ductwork make the house cooler?
It will not make the system bigger, and nobody should promise you a figure. What it changes is how much of what the system already makes actually arrives: pressure the unit is no longer fighting, air that still has speed when it reaches the register, and a far room on a run short enough to serve it. If one room has never worked while the rest of the house is fine, that is usually the duct rather than the capacity.
What does new ductwork cost?
It depends on how much of the run is being replaced, how many rooms it serves, what the attic allows and what the new run is built from, so there is no honest number to print on a page. You get the figure in your home, after a technician has looked and before anything is started, with no obligation to book on the day.
Which towns do you do this in?
Jupiter and the north of Palm Beach County — Juno Beach, Tequesta, Palm Beach Gardens, Jupiter Inlet Colony, North Palm Beach, Riviera Beach, Royal Palm Beach, The Acreage, Lake Worth Beach, Lantana, Palm Springs and Greenacres — plus Stuart, in Martin County. Each one has its own page on the service areas list, with the housing numbers behind what we usually find there.
