Pollen Season and Your AC Filter
Short answer: Greensboro's spring pollen can coat outdoor units and clog filters quickly. Check filters every few weeks in spring, rinse pollen off the outdoor coil gently with the power off and book a spring tune-up.
Request an AC technicianThe yellow season
Pine and tree pollen cover cars, decks and outdoor units every spring.
Filters clog faster
Check filters every two to four weeks in pollen season.
Filter ratings
Higher-rated filters catch more pollen but must suit your system's airflow.
Outdoor coil
Rinse gently with a hose after switching off the disconnect.
Don't power wash
High pressure bends coil fins.
Allergies
Air cleaners and better filters help allergy sufferers.
Windows
Keep windows closed on high-pollen days if you have allergies.
Ducts
Leaky return ducts pull in unfiltered air.
Spring tune-up
A technician cleans coils properly.
After pollen
Change the filter once more when pollen season ends.
