Protecting Your Air Ducts from Wildfire Ash: Essential Steps for Rural California Properties

When Wildfire Ash Invades Your Home: The Hidden Threat to Your Air Ducts in Rural California

California’s rural properties face an escalating wildfire threat, and while homeowners focus on protecting their structures from flames, many overlook a critical vulnerability: their air duct systems. As wildfires continue to affect California, the air quality in many regions has deteriorated significantly, and it’s essential to look for signs of soot, ash, and other debris that may have accumulated during the wildfire. For rural California property owners, protecting air ducts from wildfire ash isn’t just about maintaining indoor air quality—it’s about safeguarding your family’s health and preserving your HVAC system’s integrity.

Understanding the Wildfire Ash Threat

Wildfire and smoke contain particulate matter (PM), a mixture of solid particles and liquid droplets found in the air. PM 10 and 2.5 are microscopic solid or liquid droplets, up to 30 times smaller than the diameter of a human hair. They can be inhaled and absorbed in the bloodstream, leading to serious health problems. Rural properties are particularly vulnerable because they’re often located in wildland-urban interface zones with limited infrastructure protection.

Smoke from wildfires can seep indoors through vents, windows, and other openings. It brings harmful particles along for the ride. These pollutants often end up in our HVAC ducts. Unlike urban areas with tighter building envelopes, rural homes often have older ductwork with more potential entry points for contamination.

How Wildfire Ash Infiltrates Rural Air Duct Systems

Soot can enter an HVAC system in a variety of ways. If a system is operational, it’ll draw in smoke and ash from the outside air. The particulate in the air will clog up the coils, spread throughout the system and circulate into the building. Rural properties face additional challenges including:

Smoke doesn’t need much space to get inside. Tiny leaks in your ductwork, attic penetrations, or even unsealed wall gaps can allow pollution to seep in.

Essential Protection Steps for Rural Properties

Pre-Fire Season Preparation

Inspect and clean the ductwork: Properly sealed and insulated ducts prevent outdoor air from infiltrating the HVAC system. Ensuring that ducts are airtight can significantly improve the system’s efficiency and the quality of air being circulated. Rural homeowners should prioritize professional duct inspections annually, ideally before fire season begins.

The EPA says using a high efficiency filter, like a MERV 13 or higher, can help. Such filters can remove as much as 95% of particles that pass through it. Upgrading to a filter rated MERV 13 or higher can be especially important during smoky periods to effectively remove fine particle pollution from smoke in the indoor air.

During Wildfire Events

If you have a central-ducted air conditioning and heating system, be sure to set the system to “on” to ensure air is being filtered constantly, rather than “auto,” which runs the system intermittently. If your system brings fresh air into the home, close the fresh-air intake so that it operates in in recirculation mode to prevent outdoor smoke from getting inside.

Close any vents or air ducts (such as chimneys) that may allow ash to enter the house. Run central air conditioners on the “recirculate” option (instead of “outdoor air intake”).

Post-Fire Assessment and Cleanup

You may consider having your air ducts cleaned after a fire, but EPA recommends that air ducts only be cleaned as needed. For example, you should consider having the ducts cleaned if you find that your ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into your home from the supply registers.
