Freezing temperatures crept up on Worcester early this year, with temperatures reaching the lower 30s already at the beginning of October. A freeze warning was issued and residents were informed that the low temperatures would kill vegetation and bring an end to the growing season. Though the freeze only lasted about a week, it was long enough to get residents to call Worcester, Massachusetts heating contractors when their homes weren’t warm enough. But according to heating and air conditioning contractors in Worcester, this is a known phenomenon, and often, it’s just people overreacting after having spent so much time in warm temperatures.
