Air Duct Cleaning in West Covina, CA
Professional air duct cleaning in West Covina typically runs $350-$650 for a standard single-family home and is completed in one visit, with camera-verified results shown before we leave. West Covina’s 50-70-year-old ranch and split-level housing stock, combined with trapped freeway pollution from the I-10 and SR-60 corridors, creates duct contamination that accumulates faster than in coastal communities.

We’re Bellows Air Duct & Vent Co., and our technicians know the difference between a home off Citrus Avenue and one up in the north foothills near Merced Avenue. We’ve pulled flexible ductwork from attics above 140°F in summer and traced collapsed galvanized runs through original 1960s ranches south of the 10 Freeway. The work changes with the neighborhood, but our process doesn’t: one honest price shown before we start, camera documentation before and after, and our 90-Day Done Right Promise in writing.
Why West Covina Homes Are Different
West Covina sits deep in the eastern San Gabriel Valley air basin, which the South Coast AQMD consistently measures as one of the most particulate-polluted regions in the country. The San Gabriel Mountains trap emissions to the north, while the I-10 and SR-60 freeway corridors feed diesel particulates into the basin. Coastal LA gets onshore breezes; West Covina doesn’t.
The housing stock compounds this. Homes built during the 1950s through early 1970s suburban boom now have original galvanized or thin sheet-metal ductwork never designed for fifty years of thermal cycling. In north-side foothill neighborhoods, attics exceed 140°F, degrading flex-duct insulation and cracking mastic seals while pulling fiberglass particles directly into supply air.
Air Duct Cleaning in West Covina
Our crews serve all four ZIP codes - 91790, 91791, 91792, and 91793 - with truck stock matched to your specific setup, not a generic kit. Air Duct Cleaning from Bellows means the full supply and return network, registers, boots, and plenum, with camera verification every time.
Residential Duct Cleaning
We clean the complete system using Rotobrush and Nikro equipment sized for older ductwork. A typical residential duct cleaning for a West Covina ranch or split-level home runs $350-$650 depending on system size and accessibility. On Oak Canyon Way near the foothills, we serviced a 1965 ranch where cracked mastic joints from attic heat were pulling fiberglass insulation into the supply air. We cleaned the full network and sealed the failure points during the same visit.
Supply Duct Cleaning
The supply side is where homeowners feel the problem: dust blowing from vents, uneven cooling, rooms that never reach temperature. We clean every branch from plenum to register, then verify flow with camera footage. Full system cleaning including the air handler and coil generally falls between $550-$950. In homes with undersized ductwork from original 1950s construction, we note high static pressure points where debris accumulates fastest.
How long does a full system cleaning take for a typical West Covina ranch home?
Most complete cleanings for a single-story ranch in West Covina take four to six hours. Homes with attic ductwork in the 140°F zones near the foothills may need additional time for safe access and for sealant to set properly in hot conditions.

Dryer Vent Cleaning in West Covina
Dryer vent cleaning in West Covina typically runs $149-$289 for standard residential systems, with most jobs completed in a single visit. We serve homes across all four ZIP codes, including older ranch neighborhoods near Cameron Avenue and Vine Avenue where detached workshops with oversized vents are common. Dryer Vent Cleaning from Bellows starts with a camera inspection, not a guess.
Dryer Vent Inspection and Cleaning
Every service begins with a camera run through the full vent line. A standard cleaning for a single-story home with a four-inch vent under twenty feet runs $149-$189. Extended runs or detached workshop vents typically fall in the $189-$289 range.
Vent Rerouting
Long vent runs through unconditioned attics are inefficient by design. We reroute to shorter, straighter paths with rigid aluminum that outlasts flex duct in 140°F-plus attics. On Larkwood Drive, we reduced drying time by 40% rerouting a 60-foot attic run. Vent rerouting with rigid aluminum runs $250-$450, quoted precisely before we start.
Why do West Covina detached workshops need special dryer vent cleaning?
Detached workshops in the northern foothill zones typically have six-inch-diameter or larger vent lines running through unconditioned attics exceeding 140°F. Standard four-inch residential brushes cannot clean these effectively, leaving dangerous lint deposits. We dispatch with Rotobrush heavy-duty systems and Nikro high-velocity equipment sized for these commercial-grade lines. Call (855) 401-6006 to schedule - estimates are free.
HVAC Cleaning in West Covina
Professional HVAC cleaning in West Covina typically runs $280-$650 for a full system service, with most jobs completed in one visit. West Covina’s inland heat forces central AC to run far more hours annually than coastal units, accelerating debris accumulation on coils, blowers, and condensers. HVAC Cleaning from Bellows addresses each component with specific methods for the local climate.
Evaporator Coil and Blower Cleaning
The evaporator coil does the actual cooling work, and in West Covina’s 95-105°F summers, it collects debris fast. A dirty coil raises your DWP bill and can freeze up entirely. We clean in place with foaming agents and low-pressure rinses. A typical evaporator coil cleaning runs $180-$340. Blower cleaning, essential where freeway diesel soot accelerates buildup, runs $220-$380.
Condenser Cleaning
Your outdoor unit faces direct sun, Santa Ana winds, and fine valley dust. We wash coils, straighten bent fins, and clear debris so heat rejects properly. Condenser cleaning typically runs $160-$280 in this market. A clean condenser under West Covina’s extreme summer load drops operating costs measurably.
Why do my vents blow dusty air when the AC kicks on in summer?
Dusty blasts at startup mean your supply ducts are pulling attic air through loose joints or cracked mastic seals. West Covina’s extreme attic heat degrades flex-duct connections and sealant faster than in milder climates. We find and seal the infiltration points, then clean what’s already inside. Call (855) 401-6006 for a camera inspection - estimates are free.
Duct Repair & Sealing in West Covina
Most duct repair jobs in West Covina run $180-$650 and are completed same-day or next-day. We know which streets still have original 1950s ranch homes with galvanized ductwork, and which 1960s neighborhoods are hitting the age where flex duct collapses. Duct Repair & Sealing from Bellows fixes what we find, not what we guess.
Duct Sealing
Leaky joints are the biggest efficiency killer in older homes. Original mastic has dried and cracked after fifty-plus years in 140°F attics. We seal with fresh Guardsman mastic and reinforced mesh, then pressure-test. A typical duct sealing job runs $280-$450 for a single-zone system, and most homeowners see immediate improvement in room-to-room airflow.
Flex Duct and Metal Repair
Sharp temperature swings between winter nights in the 40s and summer afternoons above 100°F cause flex duct to sag, tear, or pull loose. We replace damaged sections with high-temperature-rated flex and mechanical fasteners. Flex duct section replacement runs $180-$380 per section. Metal duct seam repair runs $220-$480 depending on accessibility and damage extent.
What type of duct repair is most common in West Covina’s ranch homes?
Flex duct replacement and mastic resealing. The single-story ranch homes dominating 91790 and 91791 typically have long flex duct runs through unconditioned attics. After 50-70 years, that flex collapses, tears at collars, or sheds insulation. On a recent foothill job near Vine Avenue, we found cracked mastic seals and collapsed flex sections that had been pulling attic debris into supply air for years. Call (855) 401-6006 - estimates are free.
Air Quality & Sanitizing in West Covina
Air quality and sanitizing service in West Covina typically runs $275-$650 for whole-home duct treatment, with most jobs completed in a single visit. The combination of heavy particulate load, long cooling seasons, and aging ductwork creates conditions for mold, bacteria, and persistent odors that surface cleaning cannot reach. Air Quality & Sanitizing from Bellows treats the source, not the symptom.
Mold and Bacteria Treatment
We locate the moisture source - typically a cracked mastic seal or collapsed flex section - then treat affected duct with EPA-registered antimicrobial agents from Abatement Technologies. Whole-home bacteria sanitizing runs $275-$425. Localized mold treatment runs $350-$550. We verify coverage with camera documentation, not guesswork.
Odor Removal and UV Installation
Wildfire smoke from Angeles National Forest events absorbs into porous fiberglass duct lining and off-gasses for months. We remove contaminated material mechanically, then treat with oxidizing agents that break down odor molecules. Smoke and contamination odor removal runs $400-$650. For continuous suppression in hard-running West Covina systems, UV light installation runs $450-$850.
What is the most common source of odors in West Covina homes after wildfire season?
Wildfire smoke enters primarily through separated or unsealed duct joints in unconditioned attics, then absorbs into porous fiberglass duct lining where it off-gasses for months. Standard air fresheners cannot reach the embedded compounds. We locate the infiltration point, remove contaminated material, seal the breach with mastic, and treat with oxidizing agents. Call (855) 401-6006 - estimates are free.
