Local Climate Conditions

Houston's climate zone 2A represents a humid very hot climate with year-round cooling demands. With design temperatures ranging from 31°F in winter to 95°F in summer (a 64°F range), and humidity levels around 78%, the area creates specific HVAC challenges. Local wind patterns include gulf coast humidity and breezes, which affects building pressure relationships and equipment performance. The urban heat island effect in Houston can increase ambient temperatures by 5-10°F, requiring additional cooling capacity in dense areas. Air quality considerations require enhanced filtration systems due to moderate air quality conditions.
