Schedule IAQ AssessmentFrequently Asked Questions
Why is fall allergy season longer in 2025?
Climate changes have extended ragweed season by approximately 21 days, with pollen counts up 20% from previous years. Warmer temperatures allow plants to produce pollen longer into the fall.
What MERV rating is best for allergy sufferers?
MERV 8-13 filters capture most allergens including pollen, dust mites, and mold spores. MERV 13+ provides maximum protection but may require HVAC modifications for proper airflow.
How often should I change my air filter during allergy season?
During peak allergy season, check filters monthly and replace every 30-60 days instead of the standard 90 days. Heavily clogged filters reduce air quality and strain your HVAC system.
Do air purifiers work with HVAC systems?
Yes, whole-home air purifiers integrate with your HVAC system to provide comprehensive filtration. UV-C purifiers and HEPA filtration systems can eliminate 99.97% of airborne allergens.
How does HVAC maintenance help with allergies?
Regular HVAC maintenance ensures clean ducts, proper filtration, and efficient operation. Dirty coils and ducts can harbor mold and allergens, making symptoms worse.
