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.
Air Duct Cleaning in Hayward, CA
Dryer vent cleaning in Hayward costs between $95 and $210 for a standard single-story ranch home, and it’s the service we recommend most often in this city. The persistent marine layer that sits over Hayward from June through August pushes humidity into older laundry rooms and dryer exhaust runs, which turns lint from a slow-burning nuisance into a dense, damp plug. If your dryer has been taking 50 minutes to dry a regular load, call (806) 606-6902 and we’ll walk you through what the vent likely looks like before we even schedule the visit.
Why Hayward Homes Are Different
The Hayward Fault doesn’t just shape the hills; it shapes the ductwork. Thousands of 1950s and 1960s ranch homes in Hayward sit on soils that have shifted incrementally for decades, and that movement shows up in crawl spaces as disconnected flex duct, separated at the collar where the rigid plenum meets the flexible run. We see it most often in the flatlands neighborhoods like Harder-Tennyson and South Hayward, where conditioned air quietly bleeds into the crawl space instead of reaching the register. This is a geological failure mode, not an installer error, and it means duct repair in Hayward often starts with reconnecting what the fault has pulled apart.
Humidity is the other factor. Hayward sits at the bay’s edge, and ambient moisture levels run measurably higher than in Dublin or Livermore just fifteen miles east. That moisture enters leaks in older duct board and early flex duct, which most of these ranch homes still have, and creates conditions where mold and dust mites thrive. Combine that with original duct board that has gone brittle after fifty-plus years, and a routine air duct cleaning in Hayward can quickly become a repair and sealing job once we put the camera inside.
Our Main Hayward Services
Hayward homeowners call us about two things more than anything else: ductwork that needs cleaning after years of accumulated dust and debris, and HVAC systems that haven’t been properly serviced in the humidity of the bay’s edge. Both jobs start with a written price and end with a documented photo record of every run.
Air Duct Cleaning in Hayward
Air duct cleaning in a Hayward ranch home means working around original duct board that may have been installed when Eisenhower was president. The marine layer keeps particulate matter damp and sticky inside these runs, which means standard negative-pressure extraction often needs to be paired with agitation to break up the buildup. We photograph the inside of every run before and after, so you can see what fifty years of bay air has left behind. Learn more about Air Duct Cleaning in Hayward.

HVAC Cleaning in Hayward
HVAC cleaning in Hayward targets the evaporator coil, blower assembly, and the supply and return plenums, where damp bay air and household dust combine into a cohesive film that reduces system efficiency. In these ranch homes, the return side is often undersized, which makes the blower work harder and pull more air through gaps around the filter. A documented HVAC cleaning means the coil is photographed before and after. See HVAC Cleaning in Hayward for the full scope.

Before
AfterDryer Vent Cleaning in Hayward

Dryer vent cleaning in Hayward is the single most common job we do, and the reason is simple: these post-WWII ranch homes have short, sometimes convoluted dryer exhaust runs that were never designed for modern high-efficiency dryers. Lint accumulates faster, the marine layer adds moisture, and the result is a restricted vent that makes your dryer run longer and hotter. Here’s the full breakdown of Dryer Vent Cleaning work we perform in Hayward, with written pricing before anything starts.
Dryer Vent Inspection
Signs you need it
Your dryer takes two cycles to dry a normal load, or the exterior vent flap doesn’t open fully when the dryer is running.
What it costs in Hayward
Standalone dryer vent inspection in Hayward runs $75 to $115, and it’s waived when you book a cleaning at the same time.
How we do it
We run a camera from the dryer connection through the full run to the exterior termination, then give you the photos and a written recommendation if anything is blocked or disconnected.
Vent Cleaning
Signs you need it
You can smell a musty or burning odor when the dryer runs, or the vent flap is packed with visible lint.
What it costs in Hayward
Standard vent cleaning in Hayward is $95 to $210, depending on run length and access, with the price written before anything comes apart.
How we do it
We run a rotating brush through the full exhaust run while a negative-pressure collector captures the loosened lint at the dryer end, then photograph the cleaned run.
What Dryer Vent Cleaning Costs in Hayward
| Item | Typical range in Hayward |
|---|---|
| Dryer vent inspection | $75 - $115 |
| Standard vent cleaning (single-story ranch) | $95 - $210 |
| Long or complex vent run cleaning | $150 - $280 |
How often should a dryer vent be cleaned in Hayward?
Every 12 to 18 months for a typical Hayward ranch home. The bay humidity causes lint to compact faster than inland cities, so annual cleaning is the safer interval if you dry more than three loads a week.
Can a clogged dryer vent be dangerous?
Yes. A blocked vent holds heat and damp lint in a confined space, and that combination is a known fire hazard. If your dryer is unusually hot to the touch, call (806) 606-6902 before running another cycle.
Duct Repair & Sealing in Hayward

Duct repair and sealing in Hayward is often a correction of what the Hayward Fault has done over decades. Subtle foundation settling gradually pulls flex duct apart at the collar while the rigid plenum stays in place, and the result is conditioned air spilling into crawl spaces instead of living rooms. We reconnect, reseal, and document every repair. Here’s the scope of Duct Repair & Sealing we perform in Hayward, written price included.
Duct Sealing
Signs you need it
Rooms at the far end of the house stay warm in summer while your energy bill climbs, or you can feel air moving around register edges.
What it costs in Hayward
Duct sealing in Hayward typically runs $400 to $1,200 depending on total duct length and access, with the written quote before work starts.
How we do it
We locate leaks with a pressure test, seal accessible seams and joints with mastic or UL-rated tape, and photograph the results.
Flex Duct Repair
Signs you need it
One room never reaches the thermostat setting, or you find the crawl space is noticeably warm in winter.
What it costs in Hayward
Reconnecting or replacing a damaged flex duct section in Hayward runs $150 to $450 per run, depending on length and crawl space access.
How we do it
We remove the detached or collapsed section, install correctly sized flex duct with proper support, and seal both collars before testing airflow.
What Duct Repair & Sealing Costs in Hayward
| Item | Typical range in Hayward |
|---|---|
| Duct sealing (whole system) | $400 - $1,200 |
| Flex duct repair (single run) | $150 - $450 |
| Duct insulation replacement | $350 - $900 |
Why did my flex duct separate in the crawl space?
In Hayward, the most common cause is subtle foundation movement along the fault line that slowly pulls the flexible run away from the rigid plenum connection. It is a structural issue, not a workmanship one.
Can duct sealing lower my cooling bill in Hayward?
Yes. When conditioned air stops leaking into the crawl space, the system doesn’t work as hard to cool the living areas. We can run a pressure test to show the leakage rate before and after sealing. For an exact number, call (806) 606-6902.
Air Quality & Sanitizing in Hayward

Air quality and sanitizing in Hayward deals directly with what the bay’s humidity leaves behind inside duct runs: mold, bacteria, and the persistent musty smell that comes from damp dust. In these older ranch homes with leaky ductwork, the moisture problem is structural, and sanitizing without sealing the leaks is a temporary fix. We address both. Here’s the full Air Quality & Sanitizing scope for Hayward homes.
Mold Treatment
Signs you need it
You smell a damp, earthy odor when the system starts, or visible mold grows around supply registers.
What it costs in Hayward
Mold treatment in Hayward ductwork runs $600 to $1,800 depending on the extent and whether sealing is needed in the same visit.
How we do it
We apply an EPA-registered antimicrobial to the affected surfaces using a fogging method, then photograph the treated areas and document the product used.
UV Light Installation
Signs you need it
You’ve had repeated mold growth despite cleaning, or someone in the house has persistent allergy symptoms tied to the HVAC system.
What it costs in Hayward
UV light installation in Hayward runs $450 to $1,000 depending on the system size and whether we mount it at the coil or in the return.
How we do it
We install the unit at the evaporator coil or return plenum, wire it to run continuously, and verify the lamp is within manufacturer specifications.
What Air Quality & Sanitizing Costs in Hayward
| Item | Typical range in Hayward |
|---|---|
| Mold treatment (duct system) | $600 - $1,800 |
| UV light installation | $450 - $1,000 |
| Whole-system sanitizing | $350 - $950 |
Why does mold keep coming back in my Hayward ducts?
Because the moisture source is still there. Hayward’s bay humidity enters through leaks that were never sealed, and mold returns as long as damp air keeps reaching the dust inside. The fix is sanitizing plus sealing, done in the same scope. For a written number, call (806) 606-6902.
Does UV light actually kill mold in ductwork?
UV light at the coil or in the return prevents mold from growing on surfaces the light reaches. It does not remove existing mold, so we pair it with a treatment when needed.

"Flat price agreed up front, no per-vent add-ons at the end. That was the whole reason I did not call the coupon company."
- Suzanne B."The dryer vent was almost completely blocked with lint. They showed me the photograph and I understood immediately why the dryer had been running twice."
- Lucia M."They found a disconnected duct in the crawl space that had been dumping conditioned air under the house for years. Photographed it, quoted the repair, fixed it."
- Devon A.
