Our Air Duct Cleaning Process

01

System Inspection

We inspect accessible ductwork and HVAC components, noting areas of contamination, mold, or damage.

02

Negative Pressure Setup

A powerful vacuum creates negative pressure in the duct system, preventing dislodged debris from entering living spaces.

03

Agitation & Cleaning

Rotary brushes and compressed air whips dislodge debris from duct walls, which is captured by the vacuum system.

04

Component Cleaning

Registers, grilles, air handler, blower, and evaporator coil are cleaned before the system is sealed and tested.

Air Duct Cleaning FAQ for San Francisco Homeowners

How often should San Francisco homeowners get air duct cleaning?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from air duct cleaning at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need air duct cleaning?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How often should air ducts be cleaned?
Every 3–5 years for most homes. More frequently after renovations, if you have pets that shed, if you've had pest infestations, or if anyone in the home has allergies or respiratory issues.
Will duct cleaning reduce my energy bills?
Clean ducts improve airflow, reducing how hard your HVAC system works. Studies suggest improvements of 20–40% in system efficiency after cleaning heavily fouled systems.
Should I be home during duct cleaning?
Yes. The job requires access to all vents throughout the home, and you should be available to answer questions about system operation. The process takes 3–5 hours for a typical home.
Can duct cleaning remove mold?
Professional cleaning can remove mold from accessible duct surfaces. However, the source of moisture causing the mold must be addressed, or it will return.
