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.
Fast, Reliable Air Duct Cleaning Across Montclair
Air duct cleaning in Montclair typically runs $350-$650 for a full residential system, with most appointments completed in a single morning or afternoon. We’re the local Air Duct Cleaning team that serves Montclair from our Inland Empire dispatch office, and we know the difference between a coastal LA duct job and what your home actually faces out here.
Montclair sits where the Pomona Valley meets the San Bernardino County line, and that geography shapes everything about your ductwork. The marine layer that moderates air quality in Claremont and La Verne rarely pushes this far east. Instead, Santa Ana winds funnel Mojave Desert dust and mountain wildfire ash through your vents while the I-10 corridor adds diesel particulates to the mix. Your AC runs hard from June through October, recirculating that same burdened air through ductwork that may have last been cleaned when Gerald Ford was in office. We answer calls with a live person, 24/7, and we’ll give you a written price before a single vent cover comes off. Call (469) 972-3151.
Why Kestrel Air Duct Cleaning Is Montclair’s Preferred Air Duct Cleaning Company
We’ve been working under the Kingswell Guarantee since 2004, and that standard travels with us into every Montclair neighborhood. The four promises never change: written price before work begins, arrival in the window we gave you, a clean job site when we leave, and a written guarantee with a free return visit if anything fails within the coverage period.
Our technicians are background-checked, uniformed, and trained on professional-grade equipment, not box-store shop vacs. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-pressure units to pull contaminants out of your home entirely, and Abatement Technologies HEPA filtration to keep loosened particles from resettling in your living space during the cleaning. When we quote your job, the price we write down is the price you pay. No per-vent add-ons, no door-step revisions, no fogging upsells that mask problems without fixing them.
The Kingswell Way governs every visit. Say the price. Show up in the window. Leave the place cleaner. Put the guarantee in writing. Come back if it fails. That’s not a slogan we printed on a magnet. It’s how we work.
Vent Cleaning in Montclair
Vent Cleaning in Montclair means more than wiping down register covers. In this city, it means addressing supply vents that have been pushing alkaline desert dust into bedrooms and living rooms for decades, and return vents that have been pulling that same abrasive particulate back through the system to coat the blower motor and evaporator coils.
Most Montclair homes need vent cleaning when registers show gray-tan dust buildup, rooms feel stuffy despite the AC running, or the system cycles longer than it used to. A typical vent cleaning for a standard ranch-style home in Montclair runs $180-$340 for supply and return registers, with full system cleaning starting around $350.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Montclair’s post-war tract homes, these runs often travel through 130°F+ attic spaces where joint separation lets attic dust mix with your cooled air before it ever reaches the vent. We use brush agitation to dislodge buildup at the duct wall, then negative-air extraction to remove it completely.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. When these clog with alkaline particulate, the blower motor works harder, draws more amperage, and shortens its service life. Our video inspection lets you see the condition before and after we clean.
Air Duct Repair in Montclair
Air Duct Repair in Montclair addresses the specific failure mode this city’s housing stock creates. The post-war ranch homes that dominate neighborhoods north of Arrow Highway and south of Mission Boulevard were built with original sheet-metal ductwork running through unconditioned attics. Those atticas exceed 130°F for months each summer. Metal expands, contracts, and eventually separates at the joints. Every AC cycle then pulls attic dust directly into your supply air.
Repair becomes necessary when you feel weak airflow from certain vents, notice dust blowing from registers immediately after filter changes, or find your air handler filter collapsing weeks ahead of its rated interval. Typical duct repair in Montclair runs $250-$550 for joint resealing and collar repair, with more extensive replacement quoted individually after inspection.
Joint Resealing and Collar Repair
We pulled a 1962 ranch home near Arrow Highway and Monte Vista Avenue where the return duct collar had separated at the air handler, and the blower motor was caked with gray-tan alkaline dust. Using a Rotobrush whip and negative pressure with HEPA filtration, our tech restored the joint and source-removed four decades of desert particulate from the supply and return ducts. The homeowner’s Aprilaire filter had been collapsing at three weeks - after the clean and reseal, it held its rated interval for the first time in years.
Attic Duct Inspection
We inspect accessible attic runs for separation, corrosion, and insulation damage. Montclair’s alkaline dust is abrasive; it accelerates wear at joints and can corrode older galvanized fittings. Finding this early prevents the blower motor and coil damage that drives $1,200+ HVAC repair bills.
Trusted Brands We Service in Montclair
We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Montclair homeowners who want to maintain clean air between service visits. If your system uses a proprietary filter size or an older media cabinet, we’ll measure on site and source the correct replacement. Most filtration upgrades ship to our Inland Empire office within two business days, so you’re not waiting weeks for cleaner air.
Common Air Duct Cleaning Problems We See in Montclair Homes
- Attic duct joint separation from thermal cycling. Montclair’s unconditioned attics exceed 130°F in summer, causing metal ductwork to expand and contract until joints separate. Every AC cycle then pulls alkaline attic dust directly into your supply air, loading rooms with particulate that bypasses the filter entirely.
- Blower motor coated in gray-tan alkaline dust. Technicians working neighborhoods north of Arrow Highway regularly find air handler blowers caked with a pale dust distinct from LA’s darker carbon soot. This desert particulate is abrasive and accelerates motor bearing wear while reducing airflow efficiency.
- Collapsed filters running on shortened intervals. The particulate load in Montclair overwhelms standard pleated filters. Homeowners who expect 90-day intervals often find filters collapsing at three to four weeks, a clear signal that ductwork is source-loading debris faster than the filter can handle.
- Dryer vent lint accumulation beyond the trap’s reach. The same post-war construction that puts ducts in hot attics often routes dryer vents through long horizontal runs or exterior walls where lint accumulates in pathways the trap can’t reach. This creates a genuine fire risk that duct cleaning alone won’t address without proper vent cleaning service.
Pricing for Air Duct Cleaning in Montclair, CA
Most full residential duct cleanings in Montclair run between $350 and $650 for a standard single-system home. Vent cleaning alone, covering supply and return registers with brush agitation and negative-air extraction, typically falls between $180 and $340. Air duct repair, including joint resealing and collar restoration, ranges from $250 to $550 depending on accessibility and extent.
What moves your price within these ranges: system size (single vs. dual HVAC), duct accessibility (crawl space vs. open attic), contamination level (light dust vs. decades of buildup), and whether video inspection reveals joint separation requiring repair before cleaning is effective. We do not quote per-vent pricing. One flat price per system, agreed in writing before work starts. No door-step revisions, no fogging upsells, no “we found something unexpected” add-ons.

FAQs About Air Duct Cleaning in Montclair
Montclair’s position at the eastern end of the Pomona Valley puts it beyond the reach of the marine layer, so ducts here coat with a pale gray-tan alkaline dust from Mojave desert particulates and I-10 diesel soot rather than the darker carbon mix found in LA. The 130°F+ unconditioned attics in Montclair’s post-war tract homes pull those abrasive particles through separated duct joints on every AC cycle, loading the system faster than coastal homes experience. Call (469) 972-3151 if your filters are collapsing early or your vents show that distinctive gray-tan buildup.
Genuine duct cleaning source-removes the organic load and particulate that microbial growth feeds on, using mechanical brush agitation and negative-air extraction to physically pull debris from the duct wall. Fogging sanitiser deposits a chemical layer on top of existing buildup without removing it, leaving the food source in place for the next AC cycle to redistribute. We don’t offer fogging upsells because they don’t solve the underlying problem in Montclair’s dust-heavy environment. If you’re concerned about microbial growth, we inspect for it with video and address it through source removal, not masking.
Signs include weak airflow from vents even with a new filter, the system cycling longer to reach temperature, visible dust blowing from registers immediately after filter replacement, or a filter that collapses weeks ahead of its rated interval. During our pre-cleaning video inspection, we examine the blower compartment and return plenum for the gray-tan alkaline dust coating that’s common in Montclair. If we find significant buildup, we’ll show you and include blower motor cleaning in your written quote before any work begins.
Yes, and in many ways these are the homes that benefit most. Decades of accumulated alkaline desert particulate act as an abrasive that accelerates wear on the blower motor and can restrict airflow enough to raise your energy bills and strain the compressor. The 1962 ranch near Arrow Highway and Monte Vista that we cleaned had four decades of buildup; the homeowner saw immediate improvement in airflow and filter life. Our 365-Day Done Right Promise covers the work, and if anything falls short within that period, we return and make it right at no charge. Call (469) 972-3151 for a free estimate.
Yes, if your dryer vent hasn’t been cleaned in the last year. The same post-war construction common in Montclair often routes dryer vents through long horizontal runs or exterior walls where lint accumulates beyond the trap’s reach. This creates a fire hazard that duct cleaning alone won’t address. We offer dryer vent cleaning as a separate service and can schedule it during the same visit. One flat price, agreed in writing, for each system.
