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.

AfterFast, Reliable Air Duct Cleaning Across Sunnyside
Air duct cleaning in Sunnyside typically runs $350 – $650 for a full residential system, and our crews schedule within a few days of your call. If you’re noticing more dust settling on furniture near your vents, or your HVAC seems to run longer than it used to, the combination of Sunnyside’s agricultural surroundings and older ductwork is likely the cause.
We dispatch to Sunnyside from our Los Angeles scheduling office, and our technicians know the area well. They’ve cleaned ducts on the older single-family homes off Jensen Avenue and in the neighborhoods near Sunnyside High School. That local familiarity matters because Sunnyside’s housing stock, built largely between the 1950s and 1980s, presents specific challenges: flex duct in attics that degrades in summer heat, under-floor ductwork in slab homes that collects groundwater-adjacent moisture and soil, and original metal ducts that have decades of baked-on agricultural dust.
When you call (361) 326-5060, you’ll reach a live person, not a voicemail loop. We’ll give you a written price before any work starts, and every job is backed by our 365-Day Done Right Promise. If something isn’t right, we come back and make it right at no charge.
Why Hollis Air Duct Cleaning Is Sunnyside’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Sunnyside by showing up inside the quoted window and leaving the site clean. Our technicians follow The Garrison Code: uniformed, background-checked, and accountable. Homeowners here have told us they chose Hollis because the last crew they hired gave a phone estimate that doubled once the truck arrived. That doesn’t happen with us. The price is written down before we touch your system, and it does not move at the door.
Our response time to Sunnyside is typically two to four business days for standard scheduling, which matches how this work should be done: thoroughly, not rushed. We know that after almond and grape harvests, calls spike because fine dust and pollen push through every gap in a home’s envelope. We plan for that seasonal rhythm. When we clean ducts near the Sunnyside County Club area or along the older streets south of Central Avenue, we’re not guessing at what we’ll find. We’ve seen the baked-on dust in attic runs, the pest debris in under-floor flex, and the pollen loading that comes with living surrounded by active farmland.
Ductwork Cleaning in Sunnyside
Ductwork Cleaning in Sunnyside means removing the accumulated agricultural dust, pollen, and debris that settles in HVAC systems through our long, dry, windy seasons. A typical residential job here runs $350 – $650 depending on system size and accessibility, with commercial systems starting around $800. Most Sunnyside homes need this every three to five years, though homes directly adjacent to active fields may need it more often during high-pollen years.
Our crews use Rotobrush rotary brush systems for the main trunk lines and branch ducts, which physically scrubs buildup off duct walls rather than just vacuuming loose debris. For heavily loaded systems, especially in older homes with decades of accumulated dust, we bring in Nikro negative-air machines that maintain suction throughout the entire cleaning process so nothing resettles in your home.
What the Process Covers
We clean supply ducts, return ducts, the main trunk line, and accessible boots and registers. In Sunnyside’s slab-on-grade homes, we pay particular attention to under-floor duct runs where soil and moisture can intrude. In homes with attic ductwork, we inspect for heat-degraded flex connections that may need attention beyond cleaning.
When to Schedule
Spring and fall are peak demand in Sunnyside due to pollen and harvest dust, but January and February often have better availability. If you’re running your HVAC more and feeling less comfort, or if you’ve recently completed landscaping or construction work, that’s a practical trigger to call.
Air Duct Inspection in Sunnyside
Air Duct Inspection in Sunnyside gives homeowners a clear picture of what’s inside their ductwork before deciding on cleaning or repairs. A video inspection runs $150 – $250 as a standalone service, though we apply that cost toward your cleaning if you proceed. We recommend it for any home where the duct system is original to a 1950s – 1980s build, or where you’ve noticed uneven heating, persistent odors, or visible debris at registers.
Our inspection process uses a high-resolution camera on a flexible snake, fed through your duct system while you watch the feed in real time. In Sunnyside, we frequently find dust caked to duct walls in attic runs where summer temperatures exceed 140 degrees, effectively baking debris into place. We also find disconnected flex duct in crawl spaces, pest intrusion in under-floor systems, and occasionally mold in areas where condensation collects against the semi-arid climate’s expectations.
What the Camera Reveals
The video shows debris type, accumulation depth, duct condition, and any structural issues like disconnected joints or crushed flex. You’ll see exactly what we see, and we’ll explain what requires immediate attention versus what can be monitored.
Inspection Reports
We provide a written summary with still images from the video, noting any recommendations and their priority. If cleaning is warranted, you’ll have a fixed price before we schedule the work. No surprises.
Trusted Brands We Service in Sunnyside
Our equipment comes from manufacturers who build for commercial crews, not hardware-store hobbyists. We run Rotobrush rotary systems and Nikro negative-air machines on the cleaning side, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Sunnyside homeowners who want to maintain cleaner ducts after we’ve finished. These aren’t brands we mention to impress you; they’re tools we’ve chosen because they hold up to daily use and produce measurable results. When your Sunnyside home needs a filter upgrade or a replacement component, we typically have it on the truck or can source it quickly through our Los Angeles supply chain.
Common Air Duct Cleaning Problems We See in Sunnyside Homes
- Baked-on agricultural dust in attic ductwork. Sunnyside’s summer attic temperatures exceed 140 degrees, and when that heat meets decades of accumulated dust, the material hardens onto duct walls. Standard vacuuming won’t remove it; rotary brush agitation is required.
- Pollen loading during spring almond bloom. The orchards surrounding Sunnyside release massive pollen loads that infiltrate homes through every gap. HVAC filters clog faster, and bypassed pollen settles in ductwork, creating allergy triggers that persist indoors.
- Disconnected flex duct in older slab homes. Many Sunnyside homes built in the 1960s and 1970s used flex duct in under-floor runs. Over decades, connections loosen and sections collapse, reducing airflow to specific rooms and pulling debris from crawl spaces.
- Post-harvest fine dust infiltration. After grape and almond harvests, dry conditions keep fine soil particulate airborne for weeks. Homes without tight envelope sealing see measurable dust accumulation in return ducts within a single season.
