Central Texas Climate and HVAC
Central Texas sits in ASHRAE Climate Zone 2A (hot-humid). Summers bring average highs of 96-100°F with high humidity from May through October. Winters are mild but unpredictable — the 2021 Winter Storm Uri proved that heating capacity matters even here. Key HVAC considerations for our area include:
- 8-9 month cooling season — Your AC works harder and longer than in most of the country
- Humidity control — Proper system sizing is critical; oversized systems short-cycle and fail to dehumidify
- Attic ductwork — Most Central Texas homes run ducts through unconditioned attics that reach 130-150°F
- Hard water — Bell and McLennan County's hard water causes scale buildup on coils and drains
- Cedar pollen — December-February brings extreme pollen that clogs outdoor coils and filters
