San Antonio Climate & HVAC Considerations
San Antonio's subtropical climate creates unique HVAC demands. Summers are long, hot, and humid with temperatures regularly exceeding 95°F from June through September. AC systems run nearly continuously for 6+ months, making reliability and efficiency critical. High humidity levels require proper dehumidification—oversized AC units that short-cycle won't remove moisture effectively, creating uncomfortable, clammy indoor conditions. Winters are generally mild (lows in the 40s-50s), but occasional hard freezes (below 32°F) can occur, requiring functional heating systems. Spring brings intense cedar and oak pollen seasons, making indoor air quality and filtration especially important. Our technicians understand these local climate factors and size equipment, recommend maintenance schedules, and suggest upgrades specifically suited to San Antonio conditions.
