AfterFull System Cleaning in Woodland Hills, CA
Full system cleaning is a top-to-bottom cleaning of every component air moves through in your home: the supply and return ducts, the main trunk lines, branch runs, registers, grilles, the blower motor, evaporator coil, drain pan, and the air handler cabinet itself. Most duct cleaning companies in the San Fernando Valley clean only the duct runs and call it done. We don’t. For a typical Woodland Hills home of 1,800 to 2,600 square feet, a complete full system cleaning runs $550 – $950, and it’s the closest thing to a reset button for your indoor air. If you’re in Woodland Hills, Calabasas, Tarzana, or Winnetka and want a written price before anyone touches your system, call us at (559) 295-5878.
Cardinal Air Duct Woodland Hills is the Air Duct Cleaning in Woodland Hills specialist under the Relay Home Co. family, founded in 2005. Every full system cleaning we perform follows The Relay Standard: a written price handed to you before work starts, a live trackable arrival window, before-and-after photos of every component, and a digital invoice you can pay from your phone. No other duct cleaner in the west Valley operates this way, and it changes the whole experience.
When You Need Full System Cleaning
Full system cleaning isn’t an annual chore like changing your air filter or scheduling Residential Duct Cleaning. It’s the answer to specific, observable problems. Here’s what we hear from homeowners across Woodland Hills, from Valley Circle to the Ventura corridor:
- One room never cools or heats right. The system runs, but the bedroom at the end of the hall stays five degrees off. That’s usually a branch run packed with dust and pet hair, restricting airflow to that register.
- Dust returns within days of cleaning. You wipe the coffee table, and by Friday it’s filming over again. That’s the system recirculating particulates from the blower cabinet and coil, not from the air outside. Santa Ana wind season makes this far worse in Woodland Hills.
- You moved into a home with unknown duct history. Most resale homes in Woodland Hills were built between 1960 and 1990. Without a cleaning record, the ducts may hold decades of accumulated debris from previous owners: pet dander, construction dust, even old pest debris.
- A renovation just finished. Drywall sanding dust, sawdust, and paint overspray get pulled into the return air stream and lodge in the coil and blower. This is one of the most common full system cleaning requests we get after kitchen remodels and ADU additions in the Valley.
- Your energy bill climbs while the system strains. A fouled evaporator coil forces the compressor to run longer to hit the thermostat setpoint. That’s real money every month, and Woodland Hills summers are not forgiving.
- Musty smell when the system kicks on. That odor is usually microbial growth on the coil or in the drain pan, fed by condensation and valley dust. The fix is mechanical cleaning of the coil and pan, not an air freshener.
Our Full System Cleaning Process
We follow a documented, step-by-step protocol on every job. No shortcuts, no skipped components. Here’s how a full system cleaning works at your Woodland Hills home:
- Initial inspection and written estimate. Before any cleaning begins, our technician inspects the system, maps the duct layout, and hands you a written price. That number does not change once work begins. If we find a surprise, we stop and show you before proceeding.
- Containment setup. We use Abatement Technologies containment units to isolate the work area and seal off registers not immediately in the cleaning path. This keeps loosened debris from drifting into living spaces.
- Duct cleaning with negative-pressure extraction. We connect a Nikro HEPA-rated vacuum to the system to create negative pressure. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. We then run a Rotobrush rotary brush system through every supply and return run: trunk lines, branch lines, and drops. The spinning brush agitates caked-on dust while the vacuum pulls it out.
- Component cleaning: coil, blower, and drain pan. This is the part most duct cleaners skip. We access the air handler cabinet, clean the evaporator coil with a professional-grade coil cleaner, clean the blower motor and wheel, and clear the condensate drain pan and line. A clean coil can restore meaningful efficiency to an older system.
- Registers, grilles, and filter housing. Every register and grille is removed, wiped, and vacuumed. We clean the filter housing and install a fresh filter if requested. If your system uses an Aprilaire or Honeywell media cabinet, we stock compatible replacements on the truck.
- Photo documentation and final walkthrough. You get before-and-after photos of the ducts, coil, and blower. We walk you through what we found and what we did. The invoice is emailed or texted to your phone, pay by link, done.
Full System Cleaning Pricing in Woodland Hills
Let’s talk real numbers. Most standard full system cleanings in Woodland Hills run $550 – $950 for a typical single-family home with one HVAC system. That’s the all-in price for the duct runs, the coil, blower, drain pan, registers, and grilles.
Here’s what moves the number:
- Home size and duct count. A 1,200-square-foot condo in a Warner Center high-rise has fewer duct runs than a 4,000-square-foot home in Walnut Acres. More runs, more time, higher cost.
- Number of HVAC systems. Two systems, two air handlers, two coils. Each system is cleaned and priced separately.
- Access difficulty. Attic-mounted air handlers in Woodland Hills summer heat are harder to access than garage-mounted units. Time is a factor, and we’re upfront about it.
- Condition of the system. A coil that hasn’t been cleaned in 20 years and is caked in a felt-like mat of dust takes longer than a system cleaned three years ago.
- Additional components. We can add dryer vent cleaning, replacement media filters (Honeywell, Aprilaire), or a Guardsman filter cabinet installation to the same visit at a bundled price.
Every estimate is free. Call (559) 295-5878 and we’ll give you a written quote over the phone or after a quick inspection. No vague ranges, no door knock upsell, no pressure.
FAQs – Full System Cleaning
How much does full system cleaning cost in Woodland Hills?
Full system cleaning in Woodland Hills typically costs between $550 and $950 for a single-family home with one HVAC system, depending on home size, duct count, and equipment access. Larger homes with two systems or badly neglected coils can run higher. Call (559) 295-5878 for a free written estimate, it takes about 10 minutes.
How long does a full system cleaning take?
A complete full system cleaning in a typical Woodland Hills home takes about 4 to 7 hours, depending on system size and condition. We’ll give you a specific time window when you book, and you can track our technician’s arrival live through The Relay Standard.
How often should I have full system cleaning done?
For most Woodland Hills homes, every 3 to 5 years is the right interval. Homes with multiple pets, a heavy Santa Ana dust season, recent renovations, or occupants with allergies or asthma may need it more often. We’ll inspect and tell you what we see, not just push a schedule.
Is full system cleaning the same as regular duct cleaning?
No. Air Duct Cleaning services address only the duct runs. Full system cleaning adds the blower motor and wheel, evaporator coil, condensate drain pan, air handler cabinet, registers, and grilles. It’s the complete job, and it’s what we recommend when the system hasn’t been touched in years or you’re chasing a persistent air quality problem.
Will full system cleaning lower my energy bill?
Yes, in many cases. A clean evaporator coil and blower wheel reduce the resistance the system works against, which means the compressor and fan motor draw less current to move the same volume of air. The improvement is most noticeable in summer when Woodland Hills AC systems run daily. We can’t promise a specific percentage, but the mechanical principle is well-established.
