Ductwork Replacement in Camarillo, CA

Replacing original attic supply ducts with new R6 insulated ductwork, with a real Ventura County job to show for it.

Ductwork is easy to forget because you never see it. In many Camarillo homes the original ducts are still up in the attic years after they were installed, and when they age, dusty floors, uneven rooms and ducts that look worn are often how the house tells you.

Ductwork replacement means taking out old supply ducts and putting new insulated ducts in their place. It is different from duct sealing, which closes leaks in ducts that are still in good shape, and from air duct cleaning, which clears out what has built up inside them. A visit from an AirWorks technician is how you find out which one your home needs.

Signs Your Ducts May Need to Be Replaced

Floors and furniture that stay dusty no matter how often you clean
Ducts in the attic that are original to the home
A heating and cooling system that has not had a maintenance visit in years
Flexible ducts that look worn, crushed, torn or pulled apart when someone looks in the attic
Rooms that never feel as comfortable as the rest of the house

No one sign proves the ducts are the problem, which is why we start with a look at the whole system and not a sales pitch.

Local know-how

Good to know in Camarillo

The details that change home projects from city to city — Camarillo's utilities, water, and permit rules at a glance.

Who powers Camarillo

Southern California Edison

SCE is the electric utility here — its time-of-use rates (and PSPS wildfire shutoffs in the hills) are why right-sized, high-efficiency heat pumps and smart thermostats pay off in this area.

Southern California Gas Company — SoCalGas supplies natural gas across this area — it matters for furnace, tankless water heater, and gas-line work, and for weighing gas equipment against an all-electric heat pump.

Water in Camarillo

City of Camarillo Water Division / Camrosa Water District

Most of Camarillo is served by the city's own Water Division, while eastern Camarillo (the Mission Oaks area) is Camrosa Water District — both blend imported Calleguas water with local groundwater, and the hard-water scale that mix leaves behind is what kills water heaters and fixtures here early.

Permits & inspections

City of Camarillo Building & Safety

HVAC changeouts and water-heater swaps in Camarillo are permitted and inspected by the city's Building & Safety Division.

California's Title 24 energy code applies everywhere we work: replacing a central AC, furnace, or heat pump requires a permit, and most duct-connected changeouts also need third-party HERS verification (duct leakage / airflow testing). Water heaters need permits too. We pull the permit and schedule the HERS rater as part of the job.

The homes we work on in Camarillo

Camarillo runs from 1960s–1980s ranch tracts and the Leisure Village and Camarillo Springs communities to newer Mission Oaks and Village at the Park construction — original ducts, first-generation ACs, and scale-fouled water heaters are everyday work.

A real job in Ventura

Rodrigo in Ventura: Constantly dusty floors led to all seven attic supply ducts being replaced with new R6 ductwork

In Ventura, Ventura County, CA, constant dust on the floors can trace back to original, leaky ductwork. In this home, a first maintenance visit in years found original ducts and a dirty blower and coil; the family chose to replace all attic supply ducts with new R6 insulated duct first and plan equipment upgrades later.

Service: Ductwork replacement
Where: Ventura, Ventura County, CA
When: March 2026
Home: Original ductwork, 2001 furnace

Step 1
The visit
The family booked a tune-up because "it's been a while since we last did it" and, in their words, "the house seems to constantly have dusty floors."
Step 2
What we found
Technician Tommy found the ductwork was original to the home. The blower wheel and evaporator coil needed a deep cleaning, the 2001 furnace's blower, capacitor and inducer were outside design spec, and the contactor was pitted.
Step 3
What they chose
Replace all of the attic supply ducts, and join the Family Plan. The family put the ductwork first as the most direct fix for the dust, and chose to hold off on equipment replacement for now.

The options we put on the table

No pressure and no ultimatums. The homeowners picked the highlighted one.

2Attic insulation and air seal
3Furnace replacement
4AC replacement
5The Family Plan

What was installed

All 7 attic supply runs were replaced with new R6 insulated ductwork. The family also enrolled in the Family Plan for ongoing maintenance.

The home: A home with original ductwork, a furnace from 2001 and an AC from 2011. The homeowners had lived there about five years with no prior HVAC maintenance. First visit in late winter, March 2026.

The result

The new ductwork was installed in March 2026, on the day the family asked for. They joined the Family Plan, and left a second 5-star review after a plumbing visit in July 2026. Their first 5-star Google review, from the diagnostic visit that started the project, is quoted higher on this page.

We laid out the full picture, furnace age included, and let the family choose what to do first. They started with the ducts because that's where the dust was coming from.

The AirWorks crew

If you're dusting constantly, the source may be in your attic. A maintenance visit can show you what your ducts look like.
