Air duct cleaning removes the dust and debris that collects inside your ductwork and gets pushed back into the house every time the system runs. In the Valley, that is mostly fine desert dust, which is small enough to get past a standard filter and settle in the duct runs.
Pfaff Cleaning Co. provides air duct cleaning throughout Chandler, Gilbert, Mesa, Scottsdale, Queen Creek, Tempe, Ahwatukee, and Sun Lakes. Whip tools, a reverse air ball, and compressed air through accessible ductwork, with vacuum extraction at every register.

A lower number usually means a few vents get done and the rest get skipped. That's the difference between every run cleaned and a house that's still dusty.
“Pfaff did a great job cleaning our carpets and air ducts. Blake was professional and explained everything clearly.”
“The crew did a detailed and a clean job.cleaning our air vents and dryer vent. They were respectful of the property while doing their work. I would recommend them.”
Worth doing: visible debris at the registers, after a remodel or construction, a new-to-you home where you do not know the history, a rodent or pest issue in the system, or ducts that have never been cleaned in a house that is 10+ years old with pets.
Here is the thing about waiting: the buildup does not sit still. Every cycle pushes some of it back into the rooms you live in, and it keeps accumulating in the runs where your filter cannot reach it.
If you have been in the house ten years, have pets, or have never had it done at all, you are in the group that benefits. Pull a register cover and look with a flashlight before you decide. That coating you see is what is in every run in the house.
Newer homes are not off the hook. It is common to find drywall dust, pieces of drywall, and insulation left from construction. We have literally pulled a Lay's chip bag and Coke cans out of vents. Construction crews leave things behind, and once a vent cover goes on, nobody looks again until someone like us takes it off.
Every job includes an HVAC system inspection, supply vent cleaning, return vent cleaning, register and grille cleaning, interior duct cleaning with whip and compressed air agitation, vacuum extraction at each register, and an airflow check.
We clean the accessible ductwork throughout the system, not just the vents you can see from the floor.
A vacuum at the register pulls loose dust sitting near the opening. It does nothing to the layer that has settled and bonded along the duct wall further in, which is most of what is actually in there.
Our approach is agitation-driven. Whip tools and compressed air do the work of breaking buildup loose, and the reverse air ball drives it back toward the register where the vacuum is waiting, instead of pushing it deeper into the run. Agitation first, extraction second. The agitation is what actually cleans the duct wall, and no amount of suction substitutes for it.
Call five companies and you will get five numbers that do not look related. There is a reason.
Some quote per system, some per vent, some a flat whole-house price. A flat price sounds simple until you realize a 2,000 sqft home with 14 vents and a 1,400 sqft home with 7 take very different amounts of work, and the flat number has to cover the bigger one. Per-vent pricing means you pay for what you have and nothing more.
The low advertised numbers usually cover a scope that is not the whole system. Worth asking anyone you call three things: are you cleaning the returns or just the supplies, are you agitating or just vacuuming, and is the number you just gave me the number I will pay.
Do the math on the low quotes. A whole-house duct cleaning done properly is a few hours of work with agitation at every run, plus setup and teardown. When someone advertises the entire house for $199, that is not a discount, that is a different scope.
Ours is $55.25 per vent or return online, $65 regular, and you can count your HVAC vents and returns yourself before you call.
Visible debris or dust buildup at the registers. Dust that resettles within a day or two of cleaning the house. A musty smell when the system kicks on. Noticeably weak airflow from specific vents. Recent remodeling or construction work. A house you just moved into with no maintenance records.
The register test is the useful one. Pull a cover off and look inside with a flashlight. If you see a coating of debris, that is your answer.
After the cleaning we fog the living space with Decon 30, an EPA-registered botanical disinfectant, and mist the registers and accessible vent covers while we are at it. The label approves it on the metal, plastic, and vinyl those covers are made of, and it contains no bleach or ammonia, so it will not corrode a grille or dry out a vent flap.
What we do not do is fog disinfectant down into the duct runs themselves. The label does not cover routine duct fogging, and misting liquid into a system can leave residue on the insulation and coils. Cleaning is what removes what is in the ducts. This treats the surfaces you actually touch and breathe past.
It is not a substitute for cleaning and it does not fix a mold problem. If there is actual mold growth in your system, that is a remediation job, not a fogging job, and we will tell you. $175 up to three bedrooms, $250 for four to seven.
Bathroom and laundry room exhaust fans pack with dust and lint and lose most of their pull. A fan that cannot move air leaves moisture in the room, which is how you get mildew on the ceiling. In a laundry room it is worse, since that fan is fighting the heat and humidity coming off the dryer. Most people have never cleaned either one.
Some of those plastic covers are brittle, especially the older ones. If one breaks while we are cleaning it, that is on us and we replace it free. $50 per fan, and it is quick if we are already at the house.
Booking with us already? Whole-home air and vent fogging is often added to the same visit, $150 a visit on a monthly plan up to 3 bedrooms, $225 for 4 to 7.
Valley dust is fine enough to pass through a standard 1-inch filter, and your system runs for months straight in the summer moving air through those runs.
Attic ductwork is the other factor. Most Valley homes have flex duct in the attic, and the connections at the boots and plenum are not always sealed well, which pulls attic dust directly into the airstream. That is the real source in more homes than people expect.
Changing your filter every one to three months does more than anything else. Duct cleaning is a periodic reset, not a maintenance routine.
Every supply and every return, agitated and pulled clean.
We take our time. No job gets rushed to make room for the next one.
Since December 2024, every job Pfaff Cleaning Co. has taken on has been handled by our own team. 500+ jobs later, we’re still at a 5.0 on Google.
Duct cleaning is the service with the most overselling in this industry. We look first, we tell you what we see, and we quote a flat per-vent number so nothing changes once we are on site. We are not the cheapest quote you will get, and we are not trying to be. We price the job, not the appointment.
Locally owned, serving Chandler, Gilbert, Scottsdale, Mesa, Queen Creek, Tempe, Ahwatukee, Sun Lakes, and Paradise Valley.
People get embarrassed when we pull a register and show them what is in there. Do not be. That buildup took years, it is inside a system nobody can see into, and every house in the Valley has some version of it. Construction dust from the day it was built is often still in there, and in newer homes it is common to find pieces of drywall and insulation too.
We have literally pulled a Lay's chip bag and Coke cans out of vents. Construction crews leave things behind, and once a vent cover goes on, nobody looks again until someone like us takes it off.
We show you what we find because you should know what you are paying for, not to make a point.
If you dust on Saturday and it is back by Tuesday, if one room never gets cold, if the vents have visible buildup around the register, or if the air smells musty when the system kicks on, those are the reasons people search for duct cleaning in the first place.
Weak airflow from a single room is usually a duct problem. Weak airflow everywhere is usually the system itself, and we will tell you which one you have rather than cleaning something that was never the issue.

Air vent cleaning covers the supply registers, the return, and the duct run behind them. Air duct sanitization, or duct sanitization, is the optional step after the cleaning, where we fog the living space and mist the registers and accessible vent covers with a botanical disinfectant.
Cleaning removes what is in there. Sanitizing treats what is left on the surfaces after.

Most homes benefit from changing air filters every one to three months, depending on filter type, pets, and household activity. Checking your filter monthly is the easiest way to know if it needs replacing sooner than expected.
Air ducts collect dust, pet hair, and airborne debris over time, and that buildup can circulate throughout your home every time your HVAC system runs. Removing it helps address buildup that's already accumulated rather than only managing what's coming in going forward.
It varies by home, but many homeowners have their ducts cleaned every few years, with more frequent cleaning for homes with pets, allergies, or nearby construction. If it's been longer than that or you're not sure when it was last done, an inspection can help you figure out where you stand.
Common signs include excess dust around vents, musty odors when the HVAC runs, reduced airflow, and visible debris around registers. Recent remodeling, construction nearby, or pets in the home can all speed up how quickly these signs show up.
Most appointments take a few hours depending on home size and the number of vents and returns. Larger homes or systems with heavier buildup may take a bit longer.
Yes, our service includes cleaning accessible supply and return vents and ductwork throughout the system. We evaluate both during the initial inspection to determine where attention is needed most.
It may help reduce some odors caused by dust and debris buildup inside accessible ductwork, and our optional sanitizing fogging treatment can provide an added layer of freshness. Results vary depending on the source of the odor and the condition of the system.
Yes, dryer vent cleaning is a separate service from air duct cleaning since it addresses lint buildup inside your dryer's exhaust line rather than your home's HVAC ductwork. We generally recommend having your dryer vent cleaned about once every 10 months. Learn more about our dryer vent cleaning.
Yes, we offer HVAC system cleaning that can include coil cleaning in addition to ductwork. Which service fits best depends on what part of your system needs attention.
