Cleaning for DFW allergy season

Dallas–Fort Worth has pollen almost all year. Mountain cedar peaks in winter, roughly December through February. Tree pollen like oak, elm and pecan runs from late winter into spring, grass follows in late spring and summer, and ragweed takes over in fall. Time deep cleans and filter changes to the start of each season, and keep pollen from being tracked indoors.
