Navigating the Haze: How to Optimize Your AC during Wildfire Season In Ontario

Wildfires in Ontario can wreak havoc not just on landscapes but also on air quality, impacting the health and safety of communities. Optimizing the air conditioning (AC) system during wildfire seasons is imperative for homeowners to maintain indoor air quality and minimize fire risks. MaxCare Heating & Cooling has created this guide to help homeowners learn about the dangers of wildfires near their homes and discover actionable tips to keep their AC and home safe.

The Invisible Enemy: Smoke and Air Quality During Wildfires

While the flames of a wildfire are visibly destructive, the smoke can be a silent and insidious threat to health. Having an AC system that can help filter out these harmful particles becomes a matter of comfort and well-being.

When wildfires occur, the smoke generated is not just a singular entity but a complex mixture of gases and fine particles from burning trees, plant material, and buildings. Depending on its composition, wildfire smoke can contain anything from carbon monoxide to formaldehyde, which poses significant health risks if inhaled.

Moreover, wildfire smoke can travel great distances, carried by wind patterns, affecting regions far removed from the actual fire. This widespread impact makes understanding the risks of smoke crucial, even for those who live miles away from the closest wildfire. Adding to the complexity is the fact that smoky conditions can fluctuate rapidly. What may start as a clear day could turn hazy within a few hours, depending on the direction and speed of the wind, making real-time air quality monitoring vital.

Another often overlooked aspect is the impact on vulnerable populations. Children, the elderly, and those with preexisting health conditions like asthma or heart disease are even more at risk during smoky conditions. A well-functioning AC system equipped with proper filters becomes not just a household appliance but a critical tool for public health, especially in these groups. The air indoors can be up to five times more polluted than outdoor air, according to the Environmental Protection Agency (EPA). Therefore, optimizing an AC system during wildfire seasons isn’t a luxury—it’s a necessity for maintaining a healthy living environment.

Optimizing Your AC for Clean Indoor Air

  1. Install High-Quality Air Filters 
    Utilizing high-efficiency particulate air (HEPA) filters in your AC system can trap most airborne particles, including smoke and ash. Regular filters may not offer this efficiency level, so upgrading is recommended, especially in wildfire-prone areas.

  2. Regular Maintenance is a Must
    Before wildfire season sets in, a thorough inspection of the AC system can ensure it’s operating at peak efficiency. This includes cleaning or replacing filters, checking for leaks in ducts, and ensuring all components are functioning well. Scheduled maintenance by professionals like MaxCare Heating & Cooling can give homeowners peace of mind.

  3. Keep Windows and Doors Sealed
    Running an AC system with windows or doors open is counterproductive and dangerous during wildfire seasons. Ensure all openings are tightly sealed to prevent smoke from infiltrating indoor spaces.

  4. Use Recirculation Mode
    Many modern AC systems come with a recirculation feature. This feature, especially during smoky conditions, can help maintain indoor air quality by continuously filtering and recirculating indoor air instead of drawing in contaminated outside air.

AC and Fire Safety: Reducing Risks

  • Clear the Area Around Outdoor Units
    Debris near your outdoor AC unit can be highly combustible. Make it a habit to keep the area clean and free of leaves, paper, or other flammable materials.

  • Inspect Electrical Components
    Faulty electrical connections can be a fire hazard. A qualified technician should regularly inspect the AC unit’s electrical components.

  • Do Not Overload Circuits
    Ensure the AC unit is connected to a dedicated electrical circuit to avoid overloading, which can lead to overheating and potentially cause a fire.

  • Evacuation Readiness
    During severe wildfires, evacuation might be the only safe option. Keep important documents handy, and know how to completely turn off your AC system to prevent it from drawing in smoke or embers that could enter and damage the home.

Plan for Power Outages

Planning for power outages during wildfire seasons requires a multi-faceted approach beyond just thinking about your AC system. When a wildfire is in proximity, there’s a strong likelihood of power grid failures, either due to direct damage to infrastructure or because of preventive shutdowns aimed at reducing fire risks. In such scenarios, not only does the comfort level drop without AC, but the lack of proper air filtration could also expose residents to hazardous air quality. Here are some additional considerations for planning around power outages:

Backup Power Solutions

Investing in a backup generator is a smart move to ensure the continuous operation of essential appliances, including your AC system. Generators come in various sizes and capacities; choosing one that can handle your AC system’s load is crucial. For those who can’t afford a generator, portable power stations may offer temporary relief, powering smaller devices and possibly portable air purifiers.

Battery-operated fans and Portable Air Purifiers

In the absence of AC, battery-operated fans can help circulate air, while portable air purifiers can assist in filtering out harmful particles. These won’t replace an AC system but can provide comfort and air quality maintenance during short-term power outages.

Preparing for Manual Restart

AC systems often require manual restarts following power outages. Knowing how to safely restart the system without causing damage is important. After a power outage, wait a few minutes before turning the AC system back on to allow electrical loads to stabilize. Some modern AC units have a delay feature that automatically handles this, but it’s always good to know how to manage manually.

Being prepared for power outages during wildfire seasons can be a lifesaver, ensuring comfort, health, and safety. This makes a well-thought-out plan essential for homeowners facing the reality of AC in wildfire Ontario conditions.
