When there is wildfire smoke in the air, it is generally recommended to keep your air conditioner (AC) turned off or set to recirculate mode, depending on the specific circumstances and the air quality in your area. Here's some information to consider:
Assess the air quality: Check the air quality index (AQI) in your area. This information is typically available through local weather websites, environmental agencies, or smartphone apps. If the AQI is in the moderate to poor range or higher, it's advisable to take precautions.
Close windows and doors: To minimize the entry of outdoor smoke into your home, ensure that all windows and doors are closed tightly.
Use a high-efficiency particulate air (HEPA) filter: If you have a standalone air purifier with a HEPA filter, it can help reduce the indoor air pollutants, including smoke particles. Keep it running in the room you spend the most time in or where the air quality matters the most.
Set your AC to recirculate mode: If your air conditioner has a recirculation or "recirc" mode, use it. This will prevent outdoor air, including smoke, from being drawn inside your home. Make sure the filter in your AC is clean to maintain proper functioning.
Seek alternative methods to cool your home: If the outdoor temperatures are not excessively high and the air quality permits, consider using fans or opening windows during times when the smoke is less dense to ventilate your home. However, this option depends on the specific conditions and recommendations in your area.
Follow local authorities' guidelines: Keep an eye on updates and recommendations provided by local health departments, fire departments, or relevant authorities regarding wildfire smoke. They may offer specific guidance based on the severity of the situation in your region.
Remember, these recommendations may vary depending on the circumstances and the advice of local authorities. It's always a good idea to consult local resources or seek professional advice to make informed decisions regarding your air conditioning usage during wildfire events.
