Air Duct Cleaning in Los Angeles - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Los Angeles, CA

Dryer vent cleaning in Los Angeles is not a maintenance afterthought. It’s the difference between a dryer that finishes a load in one cycle and a dryer that overheats in a 140-degree attic in a 1959 San Fernando Valley tract home, pushing lint into a vent run that was installed before modern building code. We built this page to give Los Angeles homeowners one place to understand what each service actually involves, what it costs here, and what the work looks like when it’s done. Call (806) 606-6902 for a written price before any work begins.

Why Los Angeles Homes Are Different

Los Angeles homes do not age the way homes age in other cities. The San Fernando Valley, South Bay, and San Gabriel Valley are dominated by post-WWII tract homes built from the late 1940s through the 1970s. Many still carry their original galvanized sheet-metal trunk lines or early flex duct stapled into attic cavities that hit 140 to 160 degrees every summer. That heat does two things. It bakes flex-duct Mylar liners until they crumble, and it accelerates the breakdown of fiberglass insulation inside the duct run. So a homeowner in Reseda or Chatsworth who calls about dusty air is often looking at a duct system where the duct itself is the contamination source, not the air moving through it.

The LA Basin’s thermal inversion layer compounds the problem. The South Coast Air Basin traps ground-level ozone and PM2.5 near breathing height year-round, and Santa Ana wind events push desert dust and wildfire smoke through the Cajon and Newhall passes directly into HVAC intakes. Recurring fire events like the Woolsey, Creek, Bobcat, and Eaton fires have made post-fire duct cleaning a regular service category here in a way virtually no other metro experiences. The air your system pulls in carries more particulate load than almost anywhere else in the country, and your ductwork sits in heat that actively degrades its own interior surfaces.

Our Main Los Angeles Services

Two of our services generate the most calls from Los Angeles homeowners, and each has a dedicated page that goes deeper than this overview allows.

Air Duct Cleaning in Los Angeles

Full-system air duct cleaning in Los Angeles means negative-pressure extraction through every duct run in the home, with the inside of each run photographed before and after. The goal is to remove what the camera shows: dust, pet dander, construction debris, and, in this region, fire ash and smoke particulate. Learn more on our Air Duct Cleaning in Los Angeles page, including system-level pricing and what the photo record includes.

HVAC Cleaning in Los Angeles

HVAC cleaning in Los Angeles covers the components beyond the ducts themselves: the blower motor, evaporator coil, plenum, and condensate pan. In systems pulling basin air through the return for years, these components accumulate a coating that reduces airflow and gives mold a surface to grow on. See the full scope on our HVAC Cleaning in Los Angeles page.

Dryer Vent Cleaning in Los Angeles

Los Angeles dryers work in some of the hottest attics in the country, and most vent runs in this city’s post-war housing stock were installed decades ago with no thought to modern lint accumulation. The result is a vent path that runs long, turns hard, and sits in 150-degree heat while the dryer pushes lint through it every cycle. A clogged vent in Los Angeles does not just slow drying; it forces the dryer’s thermal fuse to trip repeatedly and pushes heated air back into a laundry room that may already be the warmest room in the house. We clean the full vent run from the dryer to the exterior termination, and we photograph the inside of that run before and after so you can see exactly what was there. This is the core of our Dryer Vent Cleaning service.

Dryer Vent Inspection

Signs you need it

Clothes take more than one full cycle to dry, or the dryer exterior feels unusually hot to the touch mid-cycle.

What it costs in Los Angeles

A full Los Angeles dryer vent inspection typically runs $89 to $175 when booked as a standalone service.

How we do it

We run a camera through the full vent path from the dryer connection to the exterior termination, then show you the footage and document the condition of every section.

Lint Removal

Signs you need it

Visible lint builds up around the exterior vent hood, or the dryer shuts itself off mid-cycle on thermal overload.

What it costs in Los Angeles

Lint removal for a Los Angeles dryer vent typically costs between $129 and $249, depending on run length and access.

How we do it

We use negative-pressure extraction at the vent termination combined with mechanical agitation through the run, then photograph the interior before and after.

Vent Rerouting

Signs you need it

The vent run exceeds 25 feet, makes multiple hard turns, or terminates through a roof penetration that keeps filling with debris.

What it costs in Los Angeles

Rerouting a dryer vent in Los Angeles typically costs $380 to $640, depending on the new path length and wall penetrations.

How we do it

We map the shortest compliant path to the exterior, replace rigid or semi-rigid duct along that route, and seal every joint with aluminum tape.

Bird Guard Installation

Signs you need it

Nesting material is visible at the exterior termination, or you hear birds or scratching sounds near the vent outlet.

What it costs in Los Angeles

Bird guard installation on a Los Angeles dryer vent typically costs $75 to $165, including the guard hardware.

How we do it

We clear any existing nesting material, then mount a galvanized or stainless guard over the termination to keep birds out while maintaining airflow.

What Dryer Vent Cleaning Costs in Los Angeles

How often should I clean my dryer vent in Los Angeles?

Annually for most Los Angeles homes, and every six months if your vent run exceeds 20 feet or passes through a hot attic cavity. The heat in San Fernando Valley attics accelerates lint hardening, which makes blockages form faster here than in cooler climates.

Can you clean the vent if my dryer is in a closet or tight space?

Yes. We work in Los Angeles laundry closets, garage corners, and utility rooms daily, and our equipment reaches vents in tight clearance. The camera inspection happens first, so you know the access plan before any cleaning begins.

Duct Repair & Sealing in Los Angeles

Duct repair in Los Angeles is often what a cleaning job reveals. When the attic heat hits 150 degrees for months on end, flex-duct Mylar liners crack, mastic sealant dries and separates, and metal trunk lines develop gaps at every joint. The result is conditioned air leaking into an attic nobody uses while rooms at the end of the run never reach the temperature on the thermostat. We find this pattern regularly in San Fernando Valley homes from the 1950s and 1960s: the duct system leaks 20 to 30 percent of its air before it ever reaches a register. Our Duct Repair & Sealing team seals and replaces damaged sections and documents every repair with before-and-after photos.

Duct Sealing

Signs you need it

Some rooms stay noticeably hotter or cooler than the rest of the house, or your energy bill climbs without a change in usage.

What it costs in Los Angeles

Duct sealing for a typical Los Angeles system runs $450 to $1,100, depending on the number of accessible joints and seam lengths.

How we do it

We locate leaks with a smoke pencil or pressure test, then apply mastic sealant or aluminum tape to each leaking seam and joint.

Flex Duct Repair

Signs you need it

You see crushed, kinked, or sagging flexible duct runs in the attic, often with visible liner debris inside the run.

What it costs in Los Angeles

Flex duct repair or replacement in Los Angeles typically runs $280 to $620 per run, depending on diameter and length.

How we do it

We remove the damaged section, install new flex duct matched to the system’s airflow needs, and seal both connections to the original trunk line.

Duct Insulation

Signs you need it

Condensation forms on exposed duct surfaces during summer, or the air emerging from vents feels warmer than the air at the plenum.

What it costs in Los Angeles

Adding or replacing insulation around Los Angeles ductwork typically costs $180 to $520 per duct run, based on material type and run length.

How we do it

We wrap the duct in new fiberglass or reflective insulation appropriate for attic temperatures and seal the insulation seams.

What Duct Repair & Sealing Costs in Los Angeles

Why is duct repair more expensive in Los Angeles than other cities?

Attic access matters. Many Los Angeles homes have low-pitch roofs and cramped attic cavities that slow the work, and repairing a 1960s metal trunk line takes more labor than sealing modern flex duct. We write the price before work starts, so the attic conditions are reflected once, not discovered later.

Can sealing my ducts actually lower my bills?

Yes. If your ducts are leaking 20 to 30 percent of conditioned air into a 150-degree attic, sealing those leaks returns that air to the rooms you live in. The savings depend on system size and leak severity, but the physics is straightforward.

Air Quality & Sanitizing in Los Angeles

Air quality in Los Angeles is a year-round concern, not a seasonal one. The inversion layer holds ground-level ozone and PM2.5 near breathing height, and Santa Ana wind events spike particulate loads with desert dust and wildfire smoke. Inside the home, the duct system acts as a distribution network for whatever enters it: mold spores that find moisture on a cooling coil, bacteria that colonize the condensate pan, and the fine ash that settles after every fire season. Our Air Quality & Sanitizing work targets these contaminants at the source, inside the duct system and on the HVAC components where they collect, using the same documented before-and-after photo standard we apply to every job.

Mold Treatment

Signs you need it

You see visible mold growth on registers, duct interior, or the evaporator coil, or a persistent musty odor comes and goes with HVAC cycles.

What it costs in Los Angeles

Mold treatment for a Los Angeles duct system typically runs $450 to $1,200, depending on the extent and location of the growth.

How we do it

We identify the moisture source first, then clean affected surfaces and apply an EPA-registered antimicrobial treatment, documenting the entire process.

Bacteria Sanitizing

Signs you need it

A sour or dirty-sock odor comes from the vents during the first minute of each cycle, often worse after humid spells.

What it costs in Los Angeles

Bacteria sanitizing of the coil, pan, and plenum in Los Angeles typically costs $250 to $550.

How we do it

We clean the coil and condensate pan, then apply a sanitizing agent to the surfaces where bacteria accumulate and re-form.

Odor Removal

Signs you need it

A smell you cannot locate follows the airflow through the house, or a fire event or heavy smoke exposure has left residual odor in the system.

What it costs in Los Angeles

Odor removal for a Los Angeles duct system runs $250 to $600, depending on the treatment method and system size.

How we do it

We clean the duct interior, then use activated carbon or oxidizer treatment matched to the odor source, with the before-and-after photo record included.

UV Light Installation

Signs you need it

Mold keeps returning on the coil even after cleaning, or a household member has respiratory sensitivity to airborne spores.

What it costs in Los Angeles

UV light installation on a Los Angeles HVAC system typically costs $400 to $850 depending on lamp style and placement.

How we do it

We mount the lamp adjacent to the evaporator coil inside the plenum, wired to operate continuously or in sync with the blower.

Air Purifier Install

Signs you need it

Your household includes allergy or asthma sufferers, or your home sits near a freeway corridor or fire-prone zone with recurring particulate intrusion.

What it costs in Los Angeles

Air purifier installation in Los Angeles typically runs $500 to $1,200 depending on the unit style and integration point.

How we do it

We install the purifier inline with your ductwork or at the air handler, sized to your system’s CFM so it treats the full volume of moving air. Brands we work with include Honeywell and Aprilaire.

What Air Quality & Sanitizing Costs in Los Angeles

Does sanitizing actually clean the air, or just the ducts?

Both, but in sequence. The treatment kills or neutralizes contaminants on the duct surfaces and coil, and the purifier or UV system then treats air as it moves. The before-and-after photo record shows what was on the surfaces before the work.

Will a UV light eliminate wildfire smoke particles from my home?

No. UV light neutralizes biological material like mold and bacteria, not particulate matter like smoke. For wildfire ash and PM2.5, you need cleaning plus filtration, which we address as part of the full air quality scope.

Brands We Service in Los Angeles

Our technicians work on systems from Honeywell, Aprilaire, and Abatement Technologies, and our vans carry common Guardsman replacement parts so repairs do not require a second visit. For a full breakdown, see our brands.
