Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Cavalero Homes Are Different
Cavalero sits where damp marine air rolls east off the Snoqualmie Valley and meets agricultural land. That combination changes what we find inside ducts here compared with drier parts of Washington. With over 150 rainy days a year and persistent humidity, mold and mildew are the real threat, not just dust accumulation.
Most homes in Cavalero are newer construction, but the area’s rural history means many were built with DIY or contractor-grade ductwork that was never properly sealed. Valley moisture and allergens slip in through those gaps. After a wet winter, the first warm spring days trigger a surge of calls from the Raging River area, homeowners smelling must when the AC kicks on for the first time. That’s colonized ductwork, and it’s a pattern our technicians know well.
HVAC systems that sit idle through cool, damp stretches don’t get the airflow needed to dry out the ducts. That stillness is what lets microbial growth take hold. In Cavalero, cleaning alone often isn’t enough, sealing the system against infiltration matters just as much.
Our Main Cavalero Services
Homeowners in Cavalero call us most often for these three jobs, each handled with The Garrison Standard of written pricing and our 365-Day Done Right Promise.
Air Duct Cleaning in Cavalero
We clean the full supply and return trunk lines, branch ducts, and registers using a Rotobrush rotary brush system or Nikro negative-air machine depending on contamination level and duct material. In Cavalero, we often pull out compacted organic matter and light mold staining that dry-climate crews rarely see. Every job gets before-and-after photos of your own ducts, and the price is written before we start. Air Duct Cleaning in Cavalero
Dryer Vent Cleaning in Cavalero
Lint buildup in dryer vents is a fire hazard anywhere, but in Cavalero’s humid environment, that lint can also hold moisture against the duct wall and accelerate corrosion. We run a rotary brush and high-velocity vacuum from the exterior cap back to the dryer connection, measuring airflow before and after. The price is flat per system, not per foot.

Duct Sealing in Cavalero
Unsealed ductwork in Cavalero pulls in valley moisture, pollen, and agricultural dust every time the system cycles. We seal accessible joints and seams with mastic and reinforced tape, then pressure-test to verify the seal holds. For homes with contractor-grade original ductwork, this often does more for air quality and energy bills than cleaning alone. Duct Sealing in Cavalero
