AfterAir Duct Cleaning in Mountain View, CA
Dryer vent cleaning in Mountain View is a job shaped by the city’s 1950s and 1960s tract homes, where original or first-generation replacement vents run long, awkward paths from laundry rooms to roof caps. When a vent clogs, airflow drops, the dryer runs hotter, and moisture lingers inside the run – a genuine fire hazard in a city where many homeowners simply don’t know their vent has never been cleaned. CleanRun opens every inspection with a written price and closes it with a documented photo record of the inside of the vent. Call (806) 606-6902 to schedule a visit.
Why Mountain View Homes Are Different
Mountain View’s residential core is built on post-WWII tract development. Neighborhoods like Monta Loma and Rex Manor are full of ranch-style homes from the early 1950s through the early 1970s, and many still run the original sheet-metal ductwork through unconditioned attic spaces. Hot attic air presses against those runs all summer, and in winter the temperature swing loosens every taped joint. Dust pulls in, air escapes, and decades of debris settle at the elbows. What makes the city unusual is the renter dynamic: Google-campus and Silicon Valley tech employment cycles workers in and out every few years, and landlords often manage maintenance remotely. Duct cleaning and vent work gets deferred in ways that don’t happen in owner-occupied Los Altos to the west. A 1965 rancher in Rex Manor may have gone forty years without anyone looking inside the return plenum.
The local climate adds a second layer. Mountain View sits at the eastern foot of the Santa Cruz Mountains, directly in the smoke corridor when fires ignite to the west – the 2020 CZU Lightning Complex being the most recent example. Homes recirculated smoke-laden air through ducts for weeks. North Bayshore, near the bay, deals with persistent salt-air humidity that accelerates corrosion on metal duct runs and promotes mold growth on damp interior surfaces. A cleaning that simply vacuums out dust does not address what salt air does to exposed metal, and a repair that doesn’t account for attic heat will fail again within a season.
Our Main Mountain View Services
Two services dominate calls from Mountain View homeowners: full air duct cleaning and complete HVAC system cleaning. Both jobs run differently here because of what sits inside the ductwork.
Air Duct Cleaning in Mountain View
Full duct cleaning in Mountain View starts with a camera inspection of the plenum and each main run. In Monta Loma ranchers, we routinely find three-inch debris shelves at the first elbow, where 1970s forced-air conversions left irregular transitions that catch dust and pet hair. The cleaning uses negative-pressure extraction with the registers sealed, so nothing we knock loose is blown back into the living space. Every run is photographed before and after, and the photo record is included with the written scope. Most single-family jobs finish in a day, and the fixed price is written before any panel comes off. Full details live on the Air Duct Cleaning in Mountain View page.
HVAC Cleaning in Mountain View
HVAC cleaning here includes the evaporator coil, blower assembly, drain pan, and the ductwork attached to the air handler. Mountain View’s salt-air humidity near North Bayshore means coils corrode faster than they do inland, and the corrosion holds dust that then recirculates. On split systems, the coil is often in a closet or attic closet, which makes access tight but not impossible. We document the coil and blower with the same before-and-after photos as the ducts. The full scope is on the HVAC Cleaning in Mountain View page.

BeforeAfterDryer Vent Cleaning in Mountain View
Dryer vent cleaning in Mountain View addresses a problem built into the housing stock. Many 1950s and 1960s ranchers in Monta Loma and Rex Manor have dryer vents that were routed through whatever ceiling cavities were available, producing long runs with three or four elbows between the dryer and the roof cap. Lint collects at each turn, and once the airflow slows, the dryer’s moisture removal drops and the heating element runs longer cycles. In older garden apartments built between the 1980s and 2000s, shared vent stacks accumulate lint from multiple units. Our Dryer Vent Cleaning service starts with a visual inspection and air-pressure measurement, follows with full removal using rotary brushes and negative air, and ends with a photo record of the vent interior from the dryer connection to the exterior cap.
Dryer Vent Inspection
Signs you need it
Clothes come out damp after a normal cycle, the dryer exterior gets hot to the touch, or the outside vent flap barely opens when the dryer runs.
What it costs in Mountain View
A standalone dryer vent inspection in Mountain View runs $45 to $90, and the written report is included even if the vent is clear.
How we do it
We check airflow at the dryer connection and the roof or wall cap, run a camera through the full vent length, and photograph every restriction or separation we find.
Vent Cleaning
Signs you need it
The dryer takes two or three cycles to dry a load, or a burning smell develops when the dryer runs on high heat.
What it costs in Mountain View
Full dryer vent cleaning in Mountain View runs $90 to $180 per run, depending on length and the number of elbows.
How we do it
We run a rotary brush through the vent from the dryer connection to the exterior cap, extract the dislodged lint with negative air, then photograph the clean interior.
Lint Removal
Signs you need it
Lint is visible at the exterior vent cap, or the dryer shuts off mid-cycle with a thermal overload error.
What it costs in Mountain View
Standalone lint removal, when the vent is otherwise in good condition, is $90 to $150 per vent in Mountain View.
How we do it
We pull the clogged material from the full vent length by hand and with rotary tools, then measure airflow before and after to confirm the restriction is gone.
What Dryer Vent Cleaning Costs in Mountain View
| Item | Typical range in Mountain View |
|---|---|
| Dryer Vent Inspection | $45 – $90 |
| Dryer Vent Cleaning (standard run) | $90 – $180 |
| Lint Removal (restricted vent) | $90 – $150 |
Why are some Mountain View dryer vent quotes so low?
A $49 coupon almost always means the company plans to upsell you once the technician is on site. The quoted price rarely covers the full run, and the work is often a shop-vac pass that doesn’t reach the far end. We write the full price before work starts.
How do I know the Mountain View vent was actually cleaned?
Our standard job record includes a before-and-after photo of the vent interior, from the dryer connection to the exterior cap. You can see the full run and verify that the lint is actually gone. Call (806) 606-6902 to schedule.
Duct Repair & Sealing in Mountain View
Duct repair and sealing in Mountain View is frequently a job of fixing what a 1970s forced-air conversion left behind. Homes in Rex Manor and Monta Loma often had wall furnaces or gravity heat replaced with forced-air systems decades ago, and the new duct runs were routed through any ceiling cavity that worked. The result is irregular geometry, mismatched transitions, and taped joints that have been failing in hot attic air for forty years. A sealed, intact duct system is the only way any cleaning or filtration investment holds up – because leaks just pull attic dust and heat right back in. Our Duct Repair & Sealing service documents every leak and separation with photos before sealing anything.
Duct Sealing
Signs you need it
Rooms at the far end of the house stay noticeably colder in summer, or your energy bill is climbing even with the same thermostat settings.
What it costs in Mountain View
Whole-system duct sealing in Mountain View runs $400 to $1,200, depending on the number of accessible ducts and the condition of existing connections.
How we do it
We trace each accessible duct run from the plenum to the register, seal every joint and transition with mastic or aluminum tape, and photograph each point before and after sealing.
Flex Duct Repair
Signs you need it
A flex duct has collapsed or been crushed by attic storage boxes, or the plastic outer liner is torn and exposing the insulation.
What it costs in Mountain View
Flex duct repair or replacement in Mountain View runs $320 to $850 per section, including the new flex duct, connectors, and mastic sealing.
How we do it
We cut out the damaged section, run new flex duct with proper support straps, reseal the connections, and confirm airflow at the register.
What Duct Repair & Sealing Costs in Mountain View
| Item | Typical range in Mountain View |
|---|---|
| Whole-system duct sealing | $400 – $1,200 |
| Flex duct repair (per section) | $320 – $850 |
| Metal duct repair (per section) | $280 – $750 |
Do Mountain View ranchers need duct repair more often than newer homes?
Yes. Original sheet-metal runs from the 1960s were built with taped seams that degrade in unconditioned attic heat. It takes about ten to fifteen years for the tape to fail, so most Monta Loma and Rex Manor homes are well past due.
What’s the risk of leaving a duct leak in a Mountain View attic?
The leak pulls attic air, dust, and insulation fibers into the conditioned space, and the furnace or air conditioner has to push harder to compensate. Sealing the leak is cheaper than paying for all that recirculated attic debris.
Air Quality & Sanitizing in Mountain View
Air quality and sanitizing work in Mountain View is driven by two local realities: the smoke corridor from the Santa Cruz Mountains and the salt-air humidity near North Bayshore. When wildfire smoke sits over the city for days, the particulates load into the ductwork and the HVAC filter, and every running cycle pushes those particles back into the living space. In bay-side apartment complexes, the persistent salt humidity promotes mold growth on damp surfaces inside the duct system. Our Air Quality & Sanitizing service treats the duct interior with EPA-registered agents and installs filtration where it actually helps, then documents the before and after with photos.
Mold Treatment
Signs you need it
A musty smell comes from the registers when the system runs, or visible mold is present on duct surfaces near the air handler.
What it costs in Mountain View
Mold treatment for ductwork in Mountain View runs $450 to $1,300, depending on whether the treatment is limited to the plenum or includes the full duct runs.
How we do it
We apply an EPA-registered antimicrobial agent to the affected duct surfaces, treat the source of the moisture that caused the growth, and document the treatment.
Odor Removal
Signs you need it
A persistent, identifiable odor – pet, smoke, food, or a prior tenant – keeps returning from the registers even after cleaning and airing.
What it costs in Mountain View
Odor removal for ductwork in Mountain View runs $300 to $800 per system, depending on the number of ducts and the strength of the odor.
How we do it
We run an odor-neutralizing agent through the duct system using a fogging process, then re-clean the registers and return the system to use.
What Air Quality & Sanitizing Costs in Mountain View
| Item | Typical range in Mountain View |
|---|---|
| Mold treatment (ductwork) | $450 – $1,300 |
| Bacteria sanitizing (full system) | $300 – $750 |
| Odor removal (per system) | $300 – $800 |
Does the wildfire smoke from the Santa Cruz Mountains affect indoor air in Mountain View?
Yes, during prolonged smoke events like the 2020 CZU Lightning Complex, smoke particles load into ductwork and recirculate for weeks. A duct sanitizing treatment after the smoke clears is a practical step. Call (806) 606-6902.
Can mold in a North Bayshore apartment duct system be fully removed?
The visible growth can be treated and the underlying moisture source addressed, but if the humidity source remains, it can return. We document the treatment and explain the moisture condition we found so the landlord can address it.
