Houston experiences three distinct pollen seasons that clog filters faster than anywhere else in Texas. Tree pollen peaks from February through April when live oaks, cedar elms, and ash trees release allergens across the metro. Grass pollen dominates May through July as St. Augustine and Bermuda grass blanket lawns. Ragweed pollen surges from August through November, coating cars and outdoor furniture with yellow dust. High humidity keeps pollen grains airborne longer and promotes mold growth inside ductwork. A standard one-inch filter saturates within two to three weeks during peak pollen season. Professional air filter changing service ensures you maintain clean airflow when allergen counts spike and indoor air quality drops.
Local building codes do not mandate specific filter types or replacement intervals, but Harris County health guidelines recommend MERV 8 or higher filters for homes with occupants who have respiratory conditions. Titan HVAC Houston understands these recommendations and stocks filters that meet local air quality standards. We have serviced HVAC systems in Houston's oldest neighborhoods, including The Heights and Montrose, where aging ductwork requires careful filter selection to avoid airflow restrictions. Our familiarity with Houston's housing stock and climate challenges ensures you receive service tailored to your home's specific needs and local environmental conditions.
