Your options
More than one right answer.
Some homes need the full negative-pressure clean; some only need the dryer vent cleared. We will say which one yours is, even when it is the smaller job.
Source removal clean
The proper method. The whole system under negative pressure while every run is agitated mechanically, so what comes loose goes into the machine rather than into the house.
Dryer vent only
The full run to the exterior. Quick, cheap, and the single highest-value thing on this list from a fire standpoint.
Coil and blower service
Often where the lost airflow actually went. Worth doing whenever the ducts are done.
Sanitizing after the clean
Only after mechanical cleaning, never instead of it. Spraying a dirty duct is perfume over a problem.
What it costs
What actually drives the price.
Duct cleaning prices swing on the number of systems, the supply runs and returns, and whether the trunk lines sit in a crawl space or an attic. Those are what we count before giving a number.
-
Number of runs and returns
Priced by the system rather than the square foot. A house with two air handlers and thirty registers is two systems, and honest quotes say so.
-
Condition inside the ducts
Ordinary household dust is a standard clean. Construction debris, pet hair through the returns or mold after water damage all take longer and need different treatment.
-
Duct material
Sheet metal takes a rotating brush. Flexible duct and duct board have to be handled far more gently, or the cleaning tears the liner and makes things worse.
-
Coil and blower access
The evaporator coil and blower wheel hold more contamination than the ducts do. Reaching them sometimes means pulling the unit, which is time.
-
Extras
Dryer vents, sanitizing and air quality sampling are each quoted separately so you can see what you are paying for rather than a single unexplained number.
Estimates are free, written and without obligation. Anything found only after starting is priced up front.
What happens
From your call to the finished job.
Walk the system
We count the runs and returns, look at the material and check the coil before quoting. A price given over the phone without any of that is a guess.
Before photographs
Inside the trunk line and a sample of the runs, so there is a record of what the system looked like before anyone touched it.
Negative pressure
The vacuum connects to the trunk and runs for the whole job, so everything dislodged leaves the building.
Agitate every run
Brushes and air whips through each run to the register. This is the part that a shop vac at the vent does not do.
After photographs
The same locations, photographed again. You judge the result rather than taking our word for it.
Done badly
What goes wrong, and why it matters.
Shortcuts that cheapen the quote and cost you later. Ask anyone you are considering about them.
-
The shop-vac-at-the-register clean
Vacuuming the first two feet of a run does nothing to the other thirty. If the whole system was not under negative pressure, it was not cleaned.
-
Sanitizing instead of cleaning
Chemical treatment on top of a dirty duct masks the smell for a few weeks and leaves the contamination in place.
-
Ignoring the coil
A clean duct feeding a fouled evaporator coil recontaminates itself, and the airflow problem you were trying to fix stays exactly where it was.
-
Aggressive tools in flex duct
A rotating steel brush will tear a flexible duct liner. The torn liner then sheds into the airstream permanently.
-
Skipping the dryer vent
It is the cheapest item and the only one on the list with a fire risk attached. Lint in a long or crushed run is how dryer fires start.
Before you hire anyone
Six questions worth asking any air duct cleaner.
Including us. If an air duct cleaner cannot answer these easily, that is the answer.
-
Do you clean to the NADCA standard, with the whole system under negative pressure?
Yes, and the answer describes it: the trunk lines, every run, agitation, the blower and the coil. A register vacuum is not a duct cleaning.
-
Is the price for the whole house, or per vent with extras?
A written number for the system before the truck arrives. The coupon price that becomes a large invoice is the trade’s reputation.
-
What equipment are you bringing — truck-mounted or portable?
Truck-mounted or equivalent negative-pressure equipment. A shop vacuum and a brush moves the dust into the rooms.
-
How will you cut and seal the access holes?
Cut where the standard allows and sealed to it afterwards. A duct left open in the attic is worse than one never cleaned.
-
Do my ducts actually need cleaning?
The honest answer is sometimes no. Cleaning is for visible mold, a renovation, an infestation or a system full of debris — not a calendar.
-
Are you insured for damage to the ductwork and the equipment?
Liability insurance with a certificate. Torn flex duct and a damaged coil are what the coverage is for.
FAQ
Choosing an air duct cleaner in Nashville
How do I choose a air duct cleaner in Nashville?
Every duct crew we run cleans to the NADCA standard, carries liability insurance on file with us, and uses truck-mounted or equivalent negative-pressure equipment rather than a portable vacuum. Ask the six questions below of anyone, including us.
Should I get more than one quote for air duct cleaning?
Yes — and compare the scope, not the total. Duct cleaning in Nashville is a flat price per system — every supply, every return, the trunk lines and the air handler — with dryer vents and sanitizing as their own lines; a price by the vent is the sign of a company that will find extra vents.
Is the cheapest air duct cleaning quote usually a bad idea?
Not automatically; a low number is information. The $49 ad is a lead, not a price; ours is the price.
Do I need a permit for air duct cleaning in Nashville?
Duct cleaning needs no permit from Metro Nashville and the surrounding counties; a technician who cuts access holes in the ductwork seals them to the standard, and ours do.
How far in advance should I book air duct cleaning?
A cleaning in Nashville is usually within the week; the job takes most of a day for a typical house, and the technician confirms the time the day before.
