Super El Niño Alert
Super El Niño summer forecast: prolonged 100°+ heat waves headed for SoCal — tune up before your AC fails. Forecasters warn of a 55% spike in AC breakdowns this summer — book preventative service before the wait list grows. Last summer’s heat wave left thousands of SoCal homes without AC for 5+ days — don’t be next. Schedule now. Avoid a $3,000 emergency replacement — an $89 tune-up catches the failures heat waves expose. Grid stress + 95°+ days = capacitors and motors fail first. Get ahead of it — book your inspection today.

of particulates is what most 1" filters actually capture — the rest builds up in your ducts

Your ducts are catching what your filter is missing.

Standard 1" pleated filters trap less than 10% of airborne particulates. Everything else — dust, dander, pollen, mold spores, construction debris, even rodent droppings — ends up coating the inside of your duct system. From there, your HVAC blower pushes it back into your home, breath after breath.

Visible dust returning to surfaces within days of cleaning. Lingering odors. Worsening allergy symptoms. Reduced airflow from registers. Black streaks around vents. All classic signs the ducts need attention.

Why choose Canyon

What you actually get when you call us.

Cleaner air, every room.

Removes the source of recirculating dust, dander, and allergens — measurable difference in surface dust, allergy symptoms, and overall freshness.

Better HVAC efficiency.

Restored airflow lets the system breathe properly. The blower works less, the coil stays cleaner, and your filters last longer between changes.

Eliminates lingering odors.

Cooking smells, smoke, pets, paint — odor-trapping particles cling to duct walls and re-circulate. A full cleaning resets that baseline.

How it works

Four steps. No surprises.

Inspect

Camera inspection of accessible duct runs to confirm contamination level and identify any structural issues before we start.

Seal & access

We seal off registers, then access the trunk lines and individual branches through purpose-built service openings — no demolition.

Clean

Powerful negative-pressure vacuum pulls debris out while rotary brushes agitate every surface. Includes blower, coil, and return drops.

Verify

Final camera check and before/after photos of representative runs. Sanitizing fog (optional) for IAQ-sensitive households.

FAQ

Air Duct Cleaning: questions homeowners ask us most.

The honest, in-plain-English answers we’d give a neighbor calling on the phone.

How often should I have my air ducts cleaned?

Every 3 to 5 years for most homes — more often if you have pets, smokers, allergy sufferers, or recent renovations that kicked up drywall dust. We always show before/after photos so you can see whether your system actually needed it.

Does duct cleaning really improve indoor air quality?

When ducts are visibly dirty (dust caked on register grilles, debris in the trunk line, visible mold), yes — meaningfully. For clean systems, the bigger IAQ wins come from upgrading filtration, adding UV, and sealing duct leaks. We tell you honestly which one will help most.

What does duct cleaning cost?

Most SGV homes run between $450 and $850 depending on number of vents, system layout, and whether a sanitizer fog is included. We give a firm quote after a quick walkthrough — no surprises.
