How Westchester and the Lower Hudson Valley Weather Loads a System in 10543
The humid continental climate that covers zip 10543 runs winter lows of teens to mid 20s and summer highs of low to mid 80s. Central equipment installed around Mamaroneck and the rest of Westchester and the Lower Hudson Valley is sized against a 8 F heating design, which is the number that decides whether a furnace keeps up on the coldest night of the year or falls behind and runs nonstop.
Housing stock shapes the repair pattern just as much as the weather. Most of the homes in and around 10543 are postwar 1946 to 1960 housing built fast with shallow crawlspaces and undersized return ducts. That construction type is the reason service calls across Westchester and the Lower Hudson Valley tend to look the same year after year.
