Indoor Air Quality in Fresno & Pleasanton Homes: What You Need to Know

Why Indoor Air Quality Matters for Homeowners

When most people think about pollution, they picture smoggy cityscapes or wildfire smoke—not their own living rooms. But the truth is, indoor air can be 2–5 times more polluted than outdoor air, according to the EPA.

In cities like Fresno, where wildfire seasons and agricultural dust are common, and Pleasanton, where pollen and urban emissions are a growing concern, indoor air quality (IAQ) plays a critical role in your family's health and comfort. Poor IAQ can lead to allergies, asthma flare-ups, respiratory illnesses, and even impact sleep quality.

Common Causes of Poor Indoor Air Quality

Several everyday factors contribute to unhealthy indoor air:

• Dirty HVAC Filters: Clogged filters can't trap dust, pollen, or allergens effectively.
• Leaky Ducts: Gaps in ductwork pull in dust, mold spores, and outdoor pollutants.
• Humidity Issues: Too much humidity can cause mold; too little dries out your skin and airways.
• VOCs (Volatile Organic Compounds): Emitted from paints, cleaning products, and furniture.
• Mold and Mildew: Especially common in poorly ventilated spaces.
• Poor Ventilation: Stale air increases pollutant concentration indoors.

Signs Your Home’s Air Quality May Be Poor

Wondering if your indoor air could be healthier? Watch for these signs:

• Persistent coughing, sneezing, or allergy symptoms
• Unusual or musty odors
• Excessive dust buildup around vents and surfaces
• High humidity or condensation on windows
• Frequent headaches or fatigue indoors
• Visible mold or mildew growth

If you notice any of these, it might be time for a professional IAQ assessment.

How to Improve Indoor Air Quality

You can take action to create a healthier home environment:

1. Change HVAC Filters Regularly
Swap your air filter every 1–3 months, especially during heavy usage seasons.

2. Schedule Routine HVAC Maintenance
A professional tune-up ensures your system circulates clean air efficiently.

3. Consider Air Purifiers and UV Light Systems
These advanced solutions can trap airborne allergens and neutralize bacteria.

4. Seal and Repair Ductwork
Prevent dust and pollutants from entering your air supply.

5. Manage Humidity Levels
Use dehumidifiers or humidifiers as needed to keep indoor humidity between 30-50%.

6. Increase Fresh Air Flow
Open windows when outdoor air quality permits or use energy recovery ventilators (ERVs).

Special IAQ Considerations for Fresno and Pleasanton Homes

• Fresno: Outdoor air quality challenges include wildfire smoke, dust from agriculture, and seasonal ozone spikes. Consider HEPA filtration and sealing windows during high-smoke days.
• Pleasanton: High pollen counts in spring and increased urban vehicle emissions year-round can impact indoor air. Regular HVAC maintenance and upgraded air filters (MERV 13+) are key.
