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.

Why Hollis Air Duct Cleaning Is South Gate’s Preferred Air Duct Cleaning Company
We’ve been working in South Gate long enough to know what the houses here hide. Most were built between the 1920s and 1960s as 2 – 3 bedroom wood-frame stucco homes on small lots, and their original duct systems were never designed for central A/C. That matters when we’re crawling through a cramped attic off Tweedy Boulevard or pulling apart a converted garage system near Independence Avenue. Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean. Every job carries our 365-Day Done Right Promise in writing – if the work fails within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Residential Air Duct Cleaning in South Gate
Residential Air Duct Cleaning in South Gate means source removal from supply ducts, return ducts, and the main trunk lines that move conditioned air through homes that were often built before central air conditioning existed. A typical full-system residential clean in South Gate runs $300 – $650, depending on the number of registers, accessibility of the attic or crawlspace, and whether we find disconnected or crushed runs that need sealing. Most South Gate homeowners schedule this service every 3 – 5 years, or sooner after renovations, pest issues, or visible dust blowing from registers.
Supply and Return Duct Cleaning
Supply ducts push cooled air into your rooms; return ducts pull it back to the air handler. In South Gate’s older homes, we often find supply boots disconnected from registers or return plenums leaking attic air. Our rotary brush system from Rotobrush agitates debris loose while a Nikro negative-air machine maintains suction so dust doesn’t escape into your living space.
Full System Cleaning with Video Inspection
We run a camera before and after the job so you see what was in there. In South Gate’s tight attics, video inspection frequently reveals crushed flex runs, rodent damage, or original metal ductwork with failed seams. The camera doesn’t lie, and the footage belongs to you.
Commercial Air Duct Cleaning in South Gate
Commercial Air Duct Cleaning in South Gate covers retail spaces, restaurants, small offices, and multi-unit residential buildings where code compliance and occupant health are on the line. A typical commercial job in this market runs $450 – $1,200 depending on square footage, system complexity, and whether the property has been converted from original use. South Gate’s commercial corridors along Firestone Boulevard and Atlantic Avenue include many older buildings with add-on HVAC systems that were never properly integrated with original ductwork.
Code-Compliant Cleaning for Converted Properties
Many South Gate commercial spaces started as something else. A former retail unit now split into offices needs ductwork that meets current ventilation standards, not 1960s specs. We document our work and provide before-and-after photos for property managers and inspectors.
Multi-Unit and Common Area Systems
Buildings with shared duct runs or individual wall units in converted garages require careful isolation so cleaning one unit doesn’t contaminate another. Our negative-air containment prevents cross-unit debris migration.
Trusted Brands We Service in South Gate
Our crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies – the same tools used in commercial and healthcare settings, not hardware-store attachments. For filtration upgrades, we stock Honeywell, Aprilaire, and Guardsman products with fast turnaround for South Gate customers. When we find a failed component during a clean, we don’t leave you waiting on a parts order from out of state. Our Los Angeles office maintains inventory for the most common repairs we see in southeast LA County’s older housing stock.
Common Air Duct Cleaning Problems We See in South Gate Homes
- Original heating-only ducts choked by added A/C. The 1950s – 60s tract homes near South Gate Park and along Independence Avenue were built with supply runs sized for a furnace blower, not a modern air handler. When central cooling was added later, the undersized ducts leak at every joint and can’t move enough air to cool the back bedrooms.
- Crushed or disconnected runs in converted garages and back units. Multi-generational living means add-on HVAC systems with flex duct routed through tight, hot spaces. We regularly find flex runs crushed under stored items or supply boots that have been blowing attic dust for years.
- Debris accumulation from Santa Ana wind events and wildfire smoke. South Gate’s semi-arid climate and periodic windstorms pull fine dust and ash into attic vents and crawlspace openings. That debris settles in ductwork and gets recirculated every time the system cycles.
- Limited attic access hiding blower motor and air handler contamination. Low-pitched roofs in these mid-century homes mean techs who don’t use proper agitation tools and negative pressure simply can’t reach or thoroughly clean the entire system.
Pricing for Air Duct Cleaning in South Gate, CA

Commercial jobs start around $450 and can reach $1,200 for larger or multi-unit properties. What moves the price: number of supply and return registers, accessibility of attic or crawlspace ductwork, whether video inspection reveals disconnected or crushed runs needing repair, and whether duct sealing with mastic is required after cleaning.

FAQs About Air Duct Cleaning in South Gate
Because the original 1950s – 60s ductwork in most South Gate tract homes was never designed for central A/C, and the joints and seams that held together under furnace pressure leak badly once a modern air handler is attached. We quote cleaning and sealing separately when possible, but we won’t pretend a clean duct system is healthy if it’s still leaking 20% of its air into the attic. Call (361) 326-5060 and we’ll show you on camera what needs what.
Yes, if they have separate HVAC systems or flex runs that branch from the main trunk. Many South Gate conversions were done without proper duct design, and those add-on runs are often the dirtiest and most damaged parts of the system. We inspect them with the same camera and clean them under the same negative-air containment.
Crushed flex runs, disconnected supply boots, rodent-damaged insulation, and original metal ductwork with failed seams or asbestos-containing material on older wraps. Low-pitched roofs limit headroom, so we use compact agitation tools and portable HEPA equipment that fits where standard vacuums won’t. We also check whether the attic venting is pulling in Firestone Boulevard corridor dust or Santa Ana debris.
The hot, dry summers and Santa Ana wind events mean HVAC systems run hard for months, pulling in dust, pollen, and occasional wildfire smoke. Most South Gate homes need cleaning every 3 – 5 years, but homes near major corridors or with recent conversions may need it sooner. Late summer and fall are our busiest seasons here as allergens peak.
No, it’s a separate service with its own flat price, though we can schedule both during the same visit. Dryer vent cleaning is worth doing while we’re on site, especially in South Gate’s older homes where long vent runs through walls or attics create lint buildup and fire risk. Ask when you call (361) 326-5060 and we’ll price both in writing.
