Professional Air Duct Cleaning That Removes Years of Hidden Contaminants
Air duct cleaning is the thorough removal of dust, debris, mold, and allergens from your HVAC ductwork using specialized equipment and proven techniques. Our certified air duct technicians use truck-mounted vacuums, rotary brushes, and HEPA filtration systems to extract contaminants that accumulate inside supply lines, return vents, and trunk lines over years of system operation. We clean every accessible component including registers, grills, plenums, and blower assemblies to restore proper airflow and indoor air quality.
Our air duct cleaners access every section of your ductwork through strategically placed entry points, ensuring we reach branch lines, trunk lines, and plenum spaces that harbor the most debris. We don't just clean what's visible—we scrub the entire network.
We follow National Air Duct Cleaners Association standards for residential duct cleaning and commercial duct cleaning, using negative air machines that create controlled suction while preventing cross-contamination between rooms during the cleaning process.
After removing visible mold growth and dust buildup, we apply EPA-registered sanitizers and disinfectants to kill remaining bacteria, viruses, and fungus spores that compromise your family's health and create persistent odors throughout your home.
Our comprehensive HVAC cleaning service addresses dryer vent lint accumulation and furnace component cleaning, including evaporator coils, condenser coils, and blower assemblies that directly affect system efficiency and fire safety.
We use inspection cameras and borescopes to document contamination levels before we start, then show you the cleaned ductwork afterward so you can see exactly what we removed and verify the quality of our work.
PJ MAC HVAC Service & Repair employs certified air duct technicians who've completed specialized training in ductwork cleaning, duct sanitizing, and indoor air quality improvement. Our team doesn't subcontract your job to untrained workers—every technician on site works directly for us and follows our strict quality standards.
We invest in professional-grade equipment that makes a measurable difference. Our truck-mounted vacuum systems generate negative pressure up to 16,000 CFM, creating suction powerful enough to extract compacted debris that portable units can't touch. We pair this suction with air whips, rotary brushes, and skipper balls that agitate and loosen contaminants stuck to duct walls.
You'll receive transparent pricing before we start. We inspect your system, measure the square footage of ductwork, and provide a written estimate that covers all labor, equipment, and materials. No hidden fees appear after we finish.
Our service includes a 30-day satisfaction guarantee. If you notice dust blowing from vents or detect odors within 30 days of our visit, we'll return and re-clean the affected areas at no charge. We also offer optional duct sealing and filter replacement services to maintain the improvements we've made.
We're licensed, bonded, and insured for both residential and commercial projects. Our liability coverage protects your property, and our workers' compensation protects you from liability if someone gets injured on your premises.
Dust clouds that blow from registers when your furnace or air handler kicks on indicate heavy debris accumulation inside supply lines and trunk lines. This happens when years of dust, pet dander, and lint coat the interior duct surfaces, then get dislodged by sudden airflow changes. You might see particles floating in sunlight near vents or notice a fine layer settling on furniture within hours of dusting.
Mold and mildew growing inside damp ductwork create distinctive musty smells that intensify when your HVAC system runs. These odors often originate from condensation on cold supply lines in humid climates or from water intrusion through leaky duct sealing. Smoke residue from previous owners, pet odors, and cooking smells also get trapped in duct debris and recirculate through your home for years.
Sneezing, coughing, watery eyes, and respiratory irritation that improve when you leave the house suggest contaminated ductwork is distributing allergens throughout your living spaces. Pollen tracked in during spring, dust mites feeding on accumulated debris, and mold spores from damp areas all become airborne each time your blower runs, creating a continuous exposure cycle.
Weak airflow from specific registers while others blow normally indicates blockages in branch lines serving those rooms. Debris accumulation, collapsed flex duct, or disconnected joints restrict air movement and force your system to work harder. You'll notice temperature differences between rooms, longer heating or cooling cycles, and higher energy bills as your HVAC unit struggles against the resistance.
Remodeling projects generate sawdust, drywall dust, and construction debris that gets sucked into return vents and distributed throughout your ductwork. Even when contractors cover vents with plastic, fine particles infiltrate the system through gaps and leaks. This contamination coats every interior surface and requires professional duct cleaning to remove completely.

We start by examining your HVAC system, locating all supply vents, return vents, and access panels throughout your property. Our technicians use inspection cameras to document current conditions inside your ductwork, identifying mold growth, debris accumulation, and any damage requiring duct repair or duct sealing. We measure the total square footage of ductwork to calculate the time and equipment needed.
We cover furniture and flooring near work areas with protective materials, then seal all registers and grills except the ones we're actively cleaning. This creates a closed system that directs maximum suction to the section we're working on. We connect our truck-mounted vacuum to your main trunk line through a large access opening, establishing negative pressure that prevents dust from escaping into your home.
Our technicians insert rotary brushes, air whips, and compressed air tools into each duct section, scrubbing the interior walls to loosen caked-on dust, pet dander, and other contaminants. The powerful vacuum simultaneously extracts dislodged debris, pulling it through the ductwork and into our collection system outside. We clean supply lines, return boxes, trunk lines, and branch lines in sequence, working from the farthest points back toward the air handler.
We remove and clean registers, grills, vent covers, and diffusers by hand, scrubbing away dust buildup and grime. We access your furnace or air handler to clean the blower assembly, evaporator coil, and filter housing where debris accumulates and restricts airflow. After mechanical cleaning, we apply EPA-registered sanitizers using foggers that coat all interior surfaces, killing bacteria, mold spores, and viruses that survived the cleaning process.
We use our inspection camera again to verify we've removed all accessible debris and document the cleaned condition. We replace your air filter with a new high-efficiency filter, reseal any access openings we created, and test your system to confirm proper airflow and operation. You'll receive before and after photos showing exactly what we removed from your ductwork.
We trust equipment and products from manufacturers who've proven their reliability in professional HVAC cleaning applications. Our truck-mounted vacuum systems come from Nikro and Abatement Technologies, delivering the suction power needed for thorough debris extraction. We use Rotobrush and Viper rotary brush systems that reach deep into ductwork without damaging interior surfaces.
For duct sanitizing and disinfection, we apply Benefect botanical disinfectants and Sporicidin mold control solutions that meet EPA standards for safety and effectiveness. Our air whips and compressed air tools come from Goodway Technologies, designed specifically for HVAC cleaning rather than general industrial use.
We install Honeywell and 3M Filtrete replacement filters that capture particles down to 0.3 microns, maintaining the air quality improvements we've achieved. Our inspection cameras are Ridgid and Milwaukee models with high-resolution displays and flexible cables that navigate tight bends in ductwork.
For duct sealing and repair, we use Hardcast mastic sealant and Nashua foil tape that meet UL 181 standards for fire resistance and longevity. Our negative air machines come from HEPA-AIRE and Pullman Ermator, featuring true HEPA filtration that captures 99.97% of particles.
Safety matters to us. Every product we bring into your home carries proper EPA registration, OSHA approval, or industry certification. We never use harsh chemicals or unproven treatments that could harm your family or pets.

Air duct cleaning removes accumulated dust, dirt, pet dander, pollen, mold spores, bacteria, lint, construction debris, insect parts, and rodent droppings that collect inside your ductwork over years of operation. Our technicians extract visible debris using mechanical brushes and powerful vacuum systems, then apply sanitizers to kill microscopic contaminants that can't be physically removed. You'll see everything from fine dust to large clumps of compacted material that's been restricting your airflow.
Schedule duct cleaning every three to five years under normal conditions, or sooner if you've completed renovations, experienced water damage, noticed mold growth, moved into a previously occupied home, or have family members with allergies or respiratory conditions. Recent construction projects require immediate cleaning because drywall dust and sawdust infiltrate ductwork despite protective measures. Homes with pets, smokers, or high dust levels benefit from more frequent cleaning every two to three years.
Contaminated ductwork continuously distributes dust throughout your home each time your HVAC system runs, coating surfaces faster than you can clean them. Your return vents pull in dust from floors and furniture, which then circulates through dirty ducts that add their own accumulated debris before blowing everything back out through supply registers. Professional duct cleaning breaks this cycle by removing the source contamination, though you'll still need to dust regularly since homes naturally generate particles from skin cells, clothing fibers, and outdoor infiltration.
Complete residential duct cleaning typically takes three to five hours depending on your home's size, ductwork accessibility, and contamination levels. Smaller homes with simple duct layouts and light debris might finish in two hours, while larger properties with extensive ductwork, multiple HVAC systems, or heavy mold contamination can require six to eight hours. Commercial duct cleaning projects often span multiple days because of greater square footage and the need to work around business operations.
Professional air duct cleaning performed by trained technicians using proper equipment won't damage your system. We adjust brush speeds and air pressure based on your duct material—flexible ductwork requires gentler treatment than rigid metal ducts. Our inspection cameras let us identify fragile sections, existing damage, and areas requiring careful handling before we start cleaning. The real risk comes from untrained operators using excessive force or inappropriate tools that can puncture ducts, disconnect joints, or damage insulation.
Duct cleaning measurably improves indoor air quality by removing contamination sources that continuously release particles into your breathing air. Studies show properly cleaned ductwork reduces airborne dust levels, eliminates mold spore distribution, and decreases allergen concentrations throughout homes. You'll notice less dust settling on surfaces, reduced allergy symptoms, and elimination of musty odors. The improvement lasts longer when you combine cleaning with regular filter replacement and address moisture problems that cause mold growth.
