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 Clovis
Air duct cleaning in Clovis typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few days of your call. Hollis Air Duct Cleaning dispatches crews from our Fresno, Central Valley office to serve Clovis homeowners directly, with same-week availability for standard appointments and written pricing confirmed before any work begins.
We’ve been working in Clovis long enough to know the difference between a 1950s west-side ranch with galvanized ducts in a shallow crawlspace and a 2015 northeast two-story with flex runs baking in a 140°F attic. That local knowledge matters because the problems we find, and the right way to fix them, are completely different. Our technicians are background-checked, uniformed, and equipped with Rotobrush rotary systems and Nikro negative-air machines. Call (361) 326-5060 for a free estimate.

We’re part of the Garrison Partners family, in business since 2004, and every Hollis location is independently owned and operated under that standard.

Vent Cleaning in Clovis
Vent Cleaning in Clovis means more than brushing off a register cover. In the older homes near downtown and the west side, we often find supply and return vents choked with decades of accumulated dust, pet hair, and cooking residue that has settled into the galvanized trunk lines. In newer northeast subdivisions off Temperance and Nees, the issue is frequently fiberglass particles from degraded flex duct liners collecting at the vent face. A proper vent cleaning removes the visible buildup and the hidden material behind it, then we HEPA-filter the space to capture what agitation loosens.
A typical vent cleaning as part of a full system service in Clovis runs $150 – $300 for register and grille cleaning with negative-air containment. Standalone vent cleaning for a single problem area starts around $200.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. When the flex inner liner has torn at the plenum collar in a hot northeast Clovis attic, fiberglass flecks collect here first. We remove the grille, brush the boot, and vacuum the run back to the trunk with a Rotobrush rotary system so the debris doesn’t just get pushed deeper.
Return Vent Cleaning
Return vents pull air back to the handler, so they attract the most dust and hair. In pre-1970 Clovis homes with shallow crawlspaces, these are often undersized and partially blocked by years of accumulation. We clean the grille, the boot, and the return trunk to restore airflow volume.
Air Duct Repair in Clovis
Air Duct Repair in Clovis is often the real solution when cleaning alone won’t fix the problem. The extreme attic heat in northeast subdivisions, where temperatures routinely exceed 140°F from June through September, collapses or tears the inner liner of flexible duct at the plenum collar. Cleaning a duct with a failed liner just stirs up more fiberglass. The collar needs repair with a proper metal takeoff, and the liner may need replacement.
We were called to a two-story home off Temperance and Nees in northeast Clovis where the upstairs system was blowing visible fiberglass flecks; an attic camera inspection showed the flex inner liner torn at the plenum collar on two supply runs, so we set negative pressure, ran agitation tools through the supply and return ducts, and replaced the failed collars with proper metal takeoffs before HEPA-filtering the space. Our tech also found the original R-6 liner flaking in three other runs and documented it so the homeowner could decide on liner repair versus full run replacement.
Air duct repair in Clovis typically ranges from $200 – $500 for collar replacement or sealing work, and $800 – $1,500 for multiple liner replacements or rerouting damaged runs. Every repair is covered by our 365-Day Done Right Promise.
Flex Liner Collar Repair
The number-one failure mode we see in Clovis’s 2000s – 2020s homes is a torn or collapsed flex liner at the plenum collar, caused by thermal cycling in 140°F+ attics. We cut back the damaged section, install a metal takeoff with a proper connection, and seal it with mastic rated for high-temperature exposure.
Crawlspace Duct Sealing
In older west-side and downtown Clovis homes, galvanized ducts in shallow crawlspaces often separate at joints or corrode through. We seal accessible leaks with duct mastic and replace crushed or disconnected sections. This work frequently improves airflow more than cleaning alone.
Trusted Brands We Service in Clovis
Hollis Air Duct Cleaning stocks filtration and repair parts from Aprilaire, Abatement Technologies, and Guardsman for Clovis jobs, with fast turnaround on components that aren’t carried in local hardware stores. Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning and Nikro negative-air machines for containment. When we find a failed Honeywell or Aprilaire media filter during a Clovis duct cleaning, we can replace it on the spot rather than scheduling a return trip. That matters in a market where many competitors run basic shop-vac setups and have to order parts.
Common Air Duct Cleaning Problems We See in Clovis Homes
- Collapsed flex liner at the plenum collar in northeast Clovis attics. The 140°F+ summer heat degrades the inner liner of R-6 and R-8 flex duct, causing it to tear or detach where it connects to the plenum. Cleaning alone releases more fiberglass; the collar needs repair with a proper metal takeoff.
- Baked-on dust in pre-1970 galvanized ducts. Older downtown and west-side Clovis homes have decades of accumulation that has hardened onto duct walls, especially in crawlspaces with poor ventilation. This requires rotary brush agitation to remove; vacuuming alone won’t touch it.
- Overlooked second HVAC systems in newer two-story homes. Many northeast Clovis subdivisions have separate upstairs and downstairs systems, but crews sometimes clean only the easily accessible one. Half the ductwork never gets touched, and the homeowner doesn’t know until we show them.
- Disconnected or crushed runs in shallow crawlspaces. The tight crawlspaces under older Clovis homes make ductwork vulnerable to damage from pests, moisture, and past service work. We find separated joints and flattened flex that kills airflow to entire rooms.
Pricing for Air Duct Cleaning in Clovis, CA
A full residential air duct cleaning in Clovis typically costs $350 – $650 for a single-system home with 10 – 20 vents. Homes with two HVAC systems, common in northeast Clovis subdivisions, run $600 – $1,100 because we’re cleaning two complete sets of supply and return ducts. Commercial duct cleaning starts around $800 and scales with system size and access difficulty.
What moves the price: number of vents and returns, accessibility (crawlspace versus attic), whether we find failed liners or disconnected runs that need repair, and if you add dryer vent cleaning. We give you one flat price per system, agreed in writing before work starts. No per-vent add-ons, no price jump at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Clovis
The flex duct inner liner fails from heat, not age. Northeast Clovis attics hit 140°F+ for months each summer, which collapses or tears the liner at the plenum collar and releases fiberglass into supply air. Fast-built tract homes from the 2000s – 2020s are actually more prone to this failure than older homes with galvanized ducts in conditioned spaces. Call (361) 326-5060 for an inspection and exact quote – estimates are free.
We remove accumulated dust, pet dander, cooking residue, and in many northeast Clovis homes, degraded fiberglass particles from failed flex duct liners. The Rotobrush rotary system knocks debris loose from duct walls, and the Nikro negative-air machine pulls it out under contained suction. We finish with HEPA filtration of the workspace. Call (361) 326-5060 to schedule – we’ll show you what we find with the attic camera before we start.
Failed liners show visible fiberglass flecks at the vent face, a sudden increase in dust after years of clean operation, or reduced airflow to specific rooms. We confirm with an attic camera inspection: a torn or collapsed liner at the plenum collar is unmistakable. Dirty ducts just have buildup; failed liners need repair before cleaning helps. Call (361) 326-5060 and we’ll diagnose it on site – estimates are free.
Yes. Each system has its own supply and return ductwork, and cleaning only one leaves half the home’s air distribution untouched. In northeast Clovis two-story homes, we price each system separately but schedule them together, with one flat written price per system before we start. Call (361) 326-5060 for a quote on your specific setup.
It’s practical to combine them. Dryer vent cleaning runs $120 – $200 in Clovis when bundled with a full duct cleaning, versus $150 – $250 as a standalone call. Central Valley lint buildup is accelerated by our hot, dry summers, and a clogged dryer vent is a genuine fire hazard. We use the same negative-air equipment and finish with a flow test. Call (361) 326-5060 to add it to your appointment.
