Your HVAC system in your home or business is only as good as the ductwork that carries the air. If your ducts are dirty, leaky, or poorly designed, your heating and cooling system has to work overtime - raising your bills and lowering your comfort. That’s where we come in!
At NW Energy Conservation, we specialize in professional air duct services for homes and businesses across Tacoma, Seattle, Renton, Puyallup, and the entire Puget Sound. Our services include duct cleaning, inspections, sealing, repair, and full replacements. You name it, we can do it. With years of hands-on experience and the latest tools, we don’t just “brush the vents.” We make sure your ductwork is performing at its best, so your family can breathe easier and your system can run more efficiently.
Over time, air ducts collect dust, pollen, pet hair, dander, and even mold spores. Every time your HVAC kicks on, those contaminants can circulate through your home. That’s not just bad for your indoor air quality — it forces your system to work harder.
At NW Energy Conservation, we use deep brushing tools and negative-pressure vacuum systems to clean your ducts thoroughly. Unlike companies that only clean what’s visible, we service the entire duct system: supply ducts, return ducts, and registers. You’ll notice:
• Cleaner, fresher indoor air
• Fewer dust particles settling on furniture
• Improved HVAC efficiency (lower energy bills)
• Relief for allergy and asthma sufferers
Did you know? The EPA has found that indoor air can be 2–5 times more polluted than outdoor air. Regular duct cleaning can make a huge difference.
Not sure if your ducts need work? Our duct inspections use cameras and specialized tools to check for:
• Dust buildup & contamination
• Leaks and disconnections
• Poorly sized or damaged ductwork
• Airflow restrictions
We provide a clear, honest assessment and explain your options. Whether it’s a quick cleaning or a full system reconfiguration, you’ll know exactly what’s happening inside your ducts.
Leaky ducts are one of the biggest hidden energy wasters in homes. In fact, the U.S. Department of Energy estimates that 20–30% of heated or cooled air is lost through duct leaks. That means you’re paying for comfort that never makes it into your living spaces.
Our duct sealing services close up leaks with professional-grade materials. The result?
• Lower utility bills
• More consistent temperatures throughout your home
• Reduced strain on your HVAC system
• Improved indoor air quality (fewer pollutants sucked in from attics or crawlspaces)
If your ducts smell musty or stale, sanitizing can help. After professionally cleaning out your ducts, we can apply safe, EPA-approved sanitizing and deodorizing treatments. This service is especially valuable if:
• Your home has had mold issues
• You’ve recently remodeled or had fire damage
• You’ve just moved into an older home
• You own pets and notice odors in your HVAC system
The result? Fresher-smelling air that is moving through a newly sanitized system and greater peace of mind for you and your loved ones.

check out our hvac faqsDuct systems in damp climates can accumulate dust and moisture over time. Below are common duct cleaning questions from Tacoma homeowners, with answers from the NW Energy pros.
As of 2026, most residential duct cleaning in the Tacoma and Seattle area costs between $400 and $800. The final price depends on the total number of vents, the accessibility of your ductwork, and the level of buildup inside the system.
Every 3 to 5 years is a common recommendation for homes in Western Washington. You may need more frequent cleaning if you have pets, suffer from allergies, or have recently completed a home remodeling project that generated excess dust.
Yes, because the damp climate can lead to moisture accumulation in ducts, which can trap mold spores and dust. Cleaning can help improve indoor air quality and support proper airflow through the HVAC system.
Yes, restricted airflow caused by heavy dust buildup forces your fan motor to work harder, increasing your energy consumption. Clean ducts ensure your system operates at the efficiency levels it was designed for, allowing the system to operate more efficiently.
Common signs include visible dust blowing from vents, musty odors when the system runs, or unexplained allergy symptoms indoors. If you remove a vent cover and see significant debris or "fuzz" on the interior walls, it may be time for a professional cleaning.
While it won't eliminate dust entirely, professional cleaning removes the "reservoir" of dust inside your HVAC system that is constantly recirculated. Many homeowners notice less buildup on surfaces after a thorough cleaning.
