Fontana housing and HVAC
Most homes are stucco houses with gas furnaces and central AC, and many older homes have aging equipment. Newer homes are often two-story with two systems. South Fontana has older single-story homes from the 1940s to 1970s with smaller ducts, while North Fontana and Sierra Lakes subdivisions were built since the 1990s.
Fontana has hot, dry summers with frequent 100°F days and mild winters. Santa Ana winds and air pollution from freight traffic affect air quality. Summer highs regularly reach the upper 90s and 100s, and winter brings cool nights in the 40s. Fontana sits in one of the most traffic-heavy freight corridors in Southern California.
