How much is post-construction duct cleaning in Phoenix?

$449 for one system with up to 12 supply vents, including returns and the main trunk. Additional supply vents are $25 each and a second system is $299. It is the same published price as a standard duct cleaning.

Is duct cleaning actually worth it after construction?

This is the clearest yes in the whole service. The EPA does not recommend routine duct cleaning, but it does list ducts clogged with excessive dust and debris as a condition where cleaning is warranted. A system that ran through drywall sanding meets that description more often than not.

How do I know if construction dust got into my ducts?

Look at a supply register and the surface directly below it. Fine gray dust that returns after you wipe it is the common sign. The more reliable question is whether the HVAC system was running while drywall was sanded. If it was, the dust is in there.

Should I wait until the work is finished?

Yes. Cleaning ducts while dust is still being produced is wasted money. Book it once the dusty trades are done and the site is cleared.

The builder says they cleaned the ducts. Is that the same thing?

Sometimes, often not. Builder cleanup frequently means vacuuming at the registers rather than putting the system under negative pressure and agitating every branch. Ask what method was used, and ask for footage. If there is no footage, there is no evidence.

Can you clean ducts in a brand new home before we move in?

Yes, and it is the easiest version of this job because the house is empty. It is also the best time to get dated before-and-after footage on file.

Does drywall dust hurt the HVAC system?

We do not make performance or efficiency promises. What we will say is what we see: fine construction dust coats duct interiors and collects at coils and blower assemblies. We clean ducts and document the rest, and anything involving the equipment itself goes to a licensed HVAC contractor.

What if you find a duct crushed or disconnected by the builder?

You get a photograph, a location, and a plain description, in writing. That is often a useful document to have during a warranty conversation. We do not repair it ourselves.

Do you do commercial or multi-unit post-construction work?

Yes. Talk to us about the scope and we will price it rather than guessing from a web form.

What is the guarantee?

90 days. If the proof footage does not show the result we documented, we come back and make it right, or you do not pay for it.

Post-construction duct cleaning in Phoenix

$449

Air duct cleaning (1 system, up to 12 supply vents)

If the HVAC system ran while drywall was being sanded, the dust is in the ductwork. This is the one case where duct cleaning is straightforwardly worth doing, and it is the case the EPA's own criteria cover. It is $449 for one system with up to 12 supply vents, using source removal with the system under continuous negative pressure.

What's included for $449

Every supply run, up to 12 vents

Each run agitated and drawn back to the collection unit. Additional vents beyond 12 are priced per vent, published below.
Returns and the main trunk

Returns pull the heaviest construction load because they are usually the closest opening to the work. Included in the base price.
Registers and grilles

Pulled, cleaned, and reinstalled. Construction dust cakes on the vanes and a wipe does not reach it.
Source removal method

Continuous negative pressure on the system while each branch is mechanically agitated, so the debris ends up in the collection unit.
Camera proof, run by run

Before-and-after footage from inside the ductwork. On a construction job the difference is usually obvious on camera.
A written finding list

Crushed flex, disconnected runs, debris left in the plenum, or drywall screws through a duct all get photographed and written up.

Signs you need this

The system ran during construction, drywall sanding, or demolition.
There is visible fine gray dust on supply registers, or on surfaces below them, that keeps coming back.
You can see dust pushed out of a register when the system starts.
You are taking handover on a new build and want the air side documented before you move in.
A remodel opened up walls or ceilings anywhere near the ductwork.
Flooring, tile cutting, or cabinetry work was done with the system running.

When you don't need this

If the HVAC system was off and sealed for the entire construction period, and the registers were covered, and you see no fine dust at the supply registers, you may genuinely not need this. Ask the builder or contractor whether the system ran and whether the returns were sealed, and look at a register or two before you book. A small remodel in a room with the door shut and the register taped over is a different situation from whole-house drywall with the air handler running. We would rather you check first. And if the work is still ongoing, wait until it is finished, because cleaning ducts before the dust stops being produced is wasted money.

Why this is the clearest case for duct cleaning

We spend a lot of the air duct cleaning page telling people they probably do not need it. This is the page where we say the opposite.

The EPA does not recommend cleaning ducts routinely. It does list, as a condition warranting cleaning, ducts clogged with excessive amounts of dust and debris. A house where the air handler ran while drywall was being sanded is the textbook version of that condition, and it is not a subtle judgment call.

Drywall dust is also not the same material as household dust. It is fine, abrasive, and generated in enormous quantity over a short window, by a process designed to turn solid material into airborne powder. The return grille is usually the nearest large opening to the work, and the system pulls it in and distributes it through every branch.

Ask one question before you book

Did the HVAC system run during the dusty work, and were the returns and registers sealed?

If the answer is that the system was off and everything was covered, you may genuinely not need this. Look at a couple of supply registers and the surfaces below them before you spend $449. If there is no fine dust returning after a wipe, save your money.

If the answer is that the system ran, or nobody knows, or the registers were open, the dust is in the ducts. That is simply how it works.

Builder cleanup is not always duct cleaning

“The ducts were cleaned” at handover can mean a lot of things.

It often means a shop vacuum held at each register for a minute or two. That removes what is visible at the opening and leaves the length of every run untouched. It is not source removal, and it will not clear fine particulate from the ribbed interior of a flex duct.

Two questions settle it. What method was used — was the system placed under continuous negative pressure with each branch agitated? And is there footage from inside the ducts? If there is no footage, there is no evidence, and that is true of us as much as anyone else. It is why every job we do produces it.

Phoenix remodels count too, not just new builds

This is not only a new-build service. A remodel that opened walls or ceilings, a floor replacement, tile cutting, or a demolition in an occupied house all produce the same result if the system was running.

The difference is that in an occupied home the dust has somewhere to settle before you notice it, so the symptom people report is usually surfaces that will not stay clean rather than an obvious problem at the register.

What we do not do

We clean and we document. We do not repair or replace ductwork, reseal joints, reroute runs, or make anything code-compliant, and we do not test or remediate for mold.

On post-construction jobs we regularly find things worth photographing: a flex run crushed behind a stud, a branch that came off its collar, construction debris left sitting in the plenum, a screw driven straight through a duct. You get the photo, the location, and plain language about what it is. On a new build that document can be genuinely useful in a warranty conversation, and it goes to a licensed contractor rather than us.

How the visit works

Confirm the count and the price The tech counts supply vents and confirms the system count with you at the door. A corrected price is given before any work starts.
Ask what was done and when Drywall, flooring, tile, demolition, and whether the system was running. That changes where we expect the heaviest load to be.
Walk the system Air handler, returns, plenum, and a sample of supply runs, so you see the starting condition.
Put the system under negative pressure Collection unit connected at the trunk, running continuously for the whole job.
Agitate every run Air whips or rotary brushes matched to the duct material, driven the length of each branch while suction holds.
Clean registers, grilles, and the plenum area Including any construction debris sitting in the plenum, which is common and rarely mentioned.
Document and send the proof Before-and-after footage and the finding list to your phone before the tech leaves.

What makes this different in the Phoenix metro

The Valley builds and remodels constantly

New construction across the southeast and west Valley, plus heavy remodel activity in the older central and north Phoenix stock, make this the most common genuinely-justified duct cleaning we do.

Builders run the system during construction

Conditioning a house during finish work is normal practice in a climate like this. It is also the mechanism that puts drywall dust into the ducts.

Flex duct in attics holds fine dust

Most Valley homes run flex duct through the attic. Its ribbed interior holds fine particulate more stubbornly than smooth sheet metal, and it is damaged by aggressive brushing, so it needs air whips rather than a rotary brush.

Drywall dust is not ordinary household dust

It is fine, abrasive, and produced in enormous volume in a short window. It behaves differently in a duct than the slow accumulation of normal living.

Handover is the moment to document

Dated before-and-after footage at handover is worth having on file, particularly on a new build where responsibility for the condition may still be a live question.
