Duct cleaning is an essential service that involves the thorough cleaning of the air ducts and ventilation systems in your home. Over time, dust, pollen, mold, and other contaminants can accumulate in your ductwork, leading to poor indoor air quality and potential health risks for your family. At RedAlert HVAC, we utilize advanced techniques and equipment to ensure that your ducts are free of debris, allergens, and pollutants. This service is particularly important in the South Bay area, where coastal humidity can promote the growth of mold and mildew, exacerbating respiratory issues. Homeowners can expect a comprehensive inspection followed by the use of high-powered vacuums and specialized brushes to remove any buildup. Additionally, we take the time to address any other concerns related to your HVAC system, ensuring optimal airflow and efficiency. Regular duct cleaning not only improves air quality but also enhances the lifespan of your HVAC system, making it a vital part of home maintenance.

Professional air duct cleaning to improve indoor air quality and system efficiency. Our duct cleaning service covers the entire South Bay corridor — from the coastal cities (Torrance, Redondo Beach, Hermosa Beach, Manhattan Beach, El Segundo) through the inland communities (Hawthorne, Gardena, Carson, Long Beach) and the Palos Verdes peninsula. Average response time across all of these is 45 Minutes, and we never add overtime charges for nights, weekends, or holidays.
If you're searching for duct cleaning, you're probably already dealing with one or more of these symptoms: Dusty home despite cleaning, Allergy symptoms indoors, Visible dust around vents, Musty odors from vents, Inconsistent airflow. Each of those points to a specific category of failure, and the right diagnostic path starts with measuring before guessing — that's the difference between a same-day fix and a return visit.
Typical duct cleaning pricing runs $385–$695 for standard scope. Our $89 diagnostic fee is waived with repair — meaning if we do the work, you don't pay the diagnostic on top. We provide a detailed written quote before any work begins, broken down by part, labor, and any optional upgrades. There are no "trip charges," no "fuel surcharges," and no hidden line items.
What's included in the $89 diagnostic: a full system inspection, electrical testing (capacitor microfarad reading, contactor pitting check, motor amp draw), refrigerant pressure readings (for cooling work), combustion analysis (for gas heating work), static-pressure measurement on the ductwork, and a written report with the readings. If the issue is non-obvious, we run a thorough enough diagnostic that we won't have to come back for the same problem.
Across the South Bay we run roughly 5K+ duct cleaning jobs per year, which gives us pattern recognition that one-off shops don't have. The same five or six failure modes account for the vast majority of calls.
We've refined this process over 15+ years of field work in South Bay. The goal is to fix the issue on the first visit when at all possible, and to never charge for parts you don't actually need.
Every technician dispatched for duct cleaning is NATE-certified (industry gold standard for HVAC competency), EPA Section 608 Universal certified (federally required for refrigerant work), and has at least 5 years of residential or light-commercial field experience. We background-check every team member, drug-test annually, and require continuing-education hours each year on new equipment from Carrier, Trane, Lennox, Goodman, Rheem, Daikin, and the rest of the major brands.
Trucks are GPS-tracked so dispatch can give you a real-time ETA, not a four-hour window. Each truck carries the most common parts for duct cleaning work — capacitors, contactors, hot-surface ignitors, flame sensors, common condensate float switches, and a stocked refrigerant kit — so most repairs happen in a single visit.
We're fully licensed & insured, carry comprehensive general liability coverage, and pull permits on any work that requires one.
Real, verified duct cleaning reviews from homeowners across South Bay. The reviews shown below match our schema.org structured data exactly.
“Our 1968 Riviera Village place hadn't had ducts cleaned in over a decade. They used a Rotobrush truck-mounted system, sealed every register, and showed me before/after photos and the debris bag. Wife's allergies have noticeably improved. Also found a disconnected return collar in the crawl space — fixed it on the spot for $90 instead of a separate trip. Three guys, four hours, done right.”

“Just finished a kitchen remodel — the contractor's plastic seal on the supply trunks failed and we got drywall dust everywhere. RedAlert came in with a Rotobrush BrushBeast, sealed every register with PVC blocking, and ran the negative-pressure cleanup. They pulled out a literal trash bag of construction debris. Air smells clean again, and the supply registers look new.”

“After our deep-cleaning my husband's chronic sinus issues went away within a week. They removed about 4 lbs of dust + pet dander from a 1,800 sqft home (they weighed it). Rotobrush + HEPA negative air. Worth every dollar. They also installed a MERV 13 filter cabinet at the same visit, took a full day for both jobs.”

“Our 12-year-old Carrier Performance 16 quit on the hottest Saturday of August. Called at 2:14 pm, tech Marco was in our driveway near Sepulveda by 3:05 — under an hour. Diagnosed a failed dual-run capacitor (45/5 µF) in fifteen minutes, had the OEM part on the truck. Total visit was 90 minutes. He also flagged that our condenser fins were salt-pitted from the marine layer and showed me how to rinse them quarterly. Honest pricing, no upsell.”

“Been on their twice-yearly tune-up plan since 2022 — Lennox Elite 16ACX outside, EL296V furnace inside. They always text the day before, show up in the window, and email the report with static-pressure and refrigerant subcooling numbers. Last spring they caught a slow R-410A leak at the schrader valve before it turned into a $1,200 problem. Worth every dollar of the $189/year membership.”

“Another company had quoted me $8,000 for a complete furnace replacement claiming a cracked heat exchanger. RedAlert sent a tech with a borescope camera, ran the unit, did a CO test in the supply plenum (came back at 0 ppm), and showed me on screen there was no crack — just a failed hot-surface ignitor. $350 part + labor and the 80% AFUE Goodman has been running clean for ten months. Will never call anyone else.”
