Is Your AC Ready for Fire Season?

Fire season in Los Angeles brings more than just visible flames on distant hillsides. Wildfire smoke and ash can travel hundreds of miles, turning your home’s indoor air into a health hazard. For Los Angeles residents, preparing your HVAC system for fire season can make the difference between breathing clean air and struggling with smoke-related health issues.

Your heating and cooling system serves as your home’s first line of defense against wildfire smoke. When properly prepared, it filters out dangerous particles and keeps your indoor air clean. However, when neglected, it can actually make the problem worse by pulling contaminated outdoor air directly into your living spaces.

Why Fire Season Threatens Your Indoor Air Quality

Wildfire smoke contains a dangerous mix of fine particles, carbon monoxide, and volatile organic compounds. These microscopic particles easily slip through standard door and window seals, gaps in your home’s construction, and most importantly, through your HVAC system if it’s not properly equipped.

These particles are so small that they can penetrate deep into your lungs and even enter your bloodstream. What makes this particularly concerning is that indoor air can actually become more polluted than outdoor air during fire season, especially if your HVAC system is pulling in contaminated air from outside.

Signs Smoke Is Impacting Your Home

Watch for these warning signs that wildfire smoke is affecting your indoor air quality:

• Persistent smoky smell that lingers even with windows closed
• Allergy-like symptoms such as coughing, sneezing, or headaches
• Visible ash or dust accumulating around air vents
• Increased dust buildup on surfaces despite keeping windows closed

If you notice any of these signs, it’s time to take immediate action to protect your indoor air quality.

How to Protect Your Indoor Air Quality During Fire Season

Upgrade to High-Efficiency HVAC Filters

Standard 1-inch filters simply can’t trap the smallest smoke particles that pose the greatest health risks. Upgrading to MERV 13 or higher filters can capture particles as small as 0.3 microns, including most wildfire smoke particles.

However, not all HVAC systems can handle high-efficiency filters without modifications. The experts at Brody Pennell can assess your system and safely install the right filter for your setup, ensuring optimal air quality without damaging your equipment.

Seal and Insulate Your Ductwork

Leaky ductwork is one of the main ways contaminated air enters your home during fire season. Gaps in ducts, especially in attics or crawl spaces, can pull smoky air directly into your living spaces.

Professional duct sealing not only improves air quality but also increases your system’s efficiency. Brody Pennell’s technicians use advanced techniques to identify and seal these hidden leaks.

Use Recirculate Mode on Your Thermostat

During high-smoke days, switch your thermostat to “recirculate” mode to stop pulling in outdoor air. This setting allows your system to filter and clean the air already inside your home without introducing new contaminated air from outside.

Check your thermostat manual or contact Brody Pennell for guidance on the proper settings for your specific system.

Install an Air Purifier or Air Scrubber

Whole-home air purification systems work alongside your HVAC system to actively remove smoke particles, odors, and other contaminants. These systems can capture particles that even high-efficiency filters might miss.

Modern air scrubbers can eliminate up to 99.9% of airborne particles and significantly reduce smoke odors, providing an extra layer of protection for your family’s health.

Schedule a Pre-Season System Check-Up

Before fire season begins, ensure your AC and ventilation systems are clean and functioning properly. Dirty coils, clogged filters, and other maintenance issues can reduce your system’s ability to filter air effectively.

A professional maintenance visit from Brody Pennell includes cleaning all components, checking filter conditions, and ensuring your system is ready to protect your indoor air quality when you need it most.
