Delray Beach, FL · duct installation

Duct installation that fixes the route, not the unit. The air's path is what's wrong.

Undersized duct chokes the system. Oversized duct lets the air lose speed on the way. And a run that bends four times to reach a back bedroom will never cool it, no matter how big a unit sits outside.

Why the size matters

Somebody picked the size of your ducts.

Few homeowners are ever told their ducts have a size. They do: a width, a length, a count of bends, chosen once for the house as it was back then. In a town where half the homes went up in the 1970s and 80s, that choice is old. Below is what happens when it was wrong; a bigger AC fixes none of it.

  • Undersized: the system goes hungry

    A blower can only push air through the duct it has. A run too narrow for its load raises the pressure the system works against, so the unit spends its life wrestling the house instead of cooling it.

  • Oversized: the air loses its push

    Air spread through a duct wider than needed slows down. It reaches the grille with no force behind it, hangs along the ceiling and never gets across the room.

  • Each bend takes its toll

    A run leaving the plenum that bends four times on the way to a back bedroom loses pressure at every bend. That room won't cool whatever size unit is outside, because the air isn't arriving.

  • A layout nobody really planned

    Most ducts took whatever route was fastest for the original builder, then got extended for a converted garage or an added bathroom. A replacement is the one chance to route it on purpose.

  • Flex duct won't stay put

    Flexible duct is a plastic sleeve over a wire coil; in an attic it droops between straps, kinks at bends and gets pinched against joists. Every droop restricts airflow from the moment it forms.

  • A bigger unit makes things worse

    Forcing more air down the same undersized run brings more pressure, more noise and the same weak breeze at the grille. The duct sets what each room really gets.

How we decide the job

Five decisions, made before any cutting.

Open any step. Replacing ducts is mostly deciding size and route. The cutting is the easy bit, and it happens last.

  1. We inspect before anyone says replaceOften the cheapest fix is the right one.
  2. We measure the house, not the old ductThe existing duct is a clue, not a plan.
  3. Route first, then sizeLength and bends cost more than people think.
  4. A quote at your home, before any workPriced after we've looked, never sooner.
  5. Install, then walk it throughYou see the result before we pack up.

Step 1 of 5

We inspect before anyone says replace

A room that never cools doesn't automatically mean new ducts. Buildup along the run, a torn joint at a collar, a stretch sagging in the attic, a damper that no longer moves: each causes the same complaint, and each costs less. One review on the profile describes an HVAC system blowing out dusty air that a full air duct cleaning sorted out.

Step 2 of 5

We measure the house, not the old duct

How many rooms the system must reach, how far away each is, where the air handler sits and what the attic framing permits. The duct already in the ceiling shows what someone once did; it doesn't show what the house needs. Copying it is how a bad layout gets rebuilt in new material and lets its owner down twice.

Step 3 of 5

Route first, then size

A short straight run and a long one with four elbows aren't equivalent at the same width. So we settle the route first (where the trunk runs, which rooms branch from it, where the returns go), and the sizes follow. This step decides whether the bedroom at the far end of the house ever feels comfortable.

Step 4 of 5

A quote at your home, before any work

The price depends on the size of the home, how much of the run is replaced and what the attic allows, so you get it on site once a technician has seen everything, before anything begins, with no obligation to book that day. One reviewer on the profile calls the rates very reasonable.

Step 5 of 5

Install, then walk it through

Out comes the old run and in goes the new one, the boots and grilles are refitted, and an adult over eighteen goes over the result with the technician: what we replaced, what we kept, and anything worth knowing we found along the way. We sweep up and put the furniture back before leaving.

Send us your question
Do my ducts need replacing, or would cleaning do?
Most people can't tell, and that's what our visit is for. Buildup along the run, a torn joint at a collar, a stretch sagging in the attic and a damper that has stopped moving all cause the same complaint, and each is cheaper to fix than a replacement. Replacement makes sense when the run itself is the problem: crushed, split along its length, or routed so badly that no cleaning will get air to the room at the end. We look first and tell you which you have.
What does it mean when a duct is the wrong size?
Every duct has a width, and the air the blower produces has to fit through it. Too narrow and the pressure the system fights rises: the unit runs longer, moves less air and wears out faster. Too wide and the air spreads and slows, reaching the grille with no force and never crossing the room. From the couch both feel the same (weak air), and a bigger AC fixes neither, because the duct decides what the house really gets.
My AC company says I need a bigger unit. Is that true?
Sometimes. But a bigger unit pushing through the same undersized run is just a louder version of the same problem, so it's worth checking the ducts before anyone quotes you a system. One review on this profile describes an HVAC system blowing out dusty air, sorted out perfectly by a full air duct cleaning. We'd rather tell you that than sell you a replacement you don't need.
Are any of your reviews from duct replacement jobs?
No, not specifically, and we'd rather say so outright. The reviews on our Delray Beach Google profile cover cleaning visits and a single repair: air ducts and dryer vents cleaned, and a roof vent cap fixed after a bad storm. Those are the closest to this work. The whole profile is on Google, one click from our reviews page.
Will new ducts make my house cooler?
They won't make the system bigger, and nobody should promise you a number. What changes is how much of the air the system already produces actually arrives: less pressure for the unit to fight, air that still has speed at the grille, and a far room on a run short enough to reach it. If one room has never worked while the rest of the house is fine, it's usually the duct, not the capacity.
How much do new ducts cost?
It depends on how much of the run gets replaced, how many rooms it serves, what the attic allows and what the new run is made from, so no honest number can be printed here. You get the price at your home, after a technician has looked and before anything begins, with no obligation to book that day.
Which towns do you install ducts in?
Delray Beach and southern Palm Beach County, including Boynton Beach, Ocean Ridge, Highland Beach and Boca Raton. Every one has its own page in the service areas list, with the housing figures behind what we usually find there.
