Indoor Air Quality in New Braunfels, TX
Duct cleaning, UV light installation, media air filters, dehumidifiers. Cedar fever and oak pollen aren't going anywhere — IAQ work makes Hill Country living tolerable for allergy-sensitive households.
Why IAQ Matters in the Hill Country
Cedar fever (peaks December-February when Ashe juniper releases pollen across the Hill Country), oak pollen (March-April), and high baseline dust from limestone soils make New Braunfels one of the harder Texas regions for allergy-sensitive households. Standard 1-inch fiberglass air filters trap less than 30% of particulate at the size that triggers allergy symptoms. Upgraded filtration, UV light on the air handler, and source-level dust control via duct cleaning all measurably improve indoor air during peak seasons.
Duct cleaning — uses a high-power negative-air machine connected to the ductwork while compressed-air whips agitate buildup. Removes years of accumulated dust, pet dander, and construction debris. Most beneficial after a remodel, after taking ownership of an older home, or if any household member has worsening allergy symptoms despite filtration upgrades.
UV lights on the air handler kill mold and bacteria that grow on the wet evaporator coil during cooling season. Cheap to install, effective against the specific microbes that thrive in air conditioning systems. Bulb replacement every 1-2 years.
Media air filters (4-5 inch thick, replaced every 6-12 months instead of every 1-3 months) capture MERV-13 to MERV-16 particulate — meaningfully better than standard filters for pollen and fine dust. Require an air handler that can accommodate the thicker filter housing.
Whole-home dehumidifiers help in shoulder seasons (March-May, October-November) when the AC isn't running enough to dehumidify but indoor humidity climbs above comfortable levels. Ducted into the return-air plenum so they treat the whole house.

Indoor Air Quality FAQ
Measurably yes in three situations: after a major renovation (construction dust settles in ducts), after taking ownership of a home that's never been serviced, or if visible mold is growing on the inside of the ducts. For typical maintenance, an upgraded media filter often provides more day-to-day benefit than duct cleaning.
Standard 1-inch fiberglass filters: every 1-3 months. Pleated 1-inch filters: every 2-3 months. Media filters (4-5 inch): every 6-12 months. Households with pets, allergies, or running the system heavily (Hill Country summers) should change more often.
UV lights kill mold and bacteria growing on the wet evaporator coil. They don't capture pollen or dust — that's the filter's job. Most effective in homes where the existing coil has obvious mold growth or musty odors are present.
Most homes don't — the AC running during the summer cooling season handles dehumidification adequately. Whole-home dehumidifiers are most useful in homes with humidity-sensitive flooring (wood, leather furniture), homes with persistent musty smells, or in shoulder seasons when the AC isn't running enough.
