What does HSPF stand for?

HSPF stands for Heating Season Performance Factor. This term is critical in the HVAC industry as it quantifies the efficiency and performance of heat pumps during their heating season. Specifically, HSPF measures the total heating output of a heat pump in British Thermal Units (BTUs) divided by the total electric energy consumed in watt-hours over the same period.

A higher HSPF rating indicates a more efficient heat pump, which can lead to lower energy costs and reduced environmental impact. This performance metric is especially important for consumers looking to make informed decisions on energy-efficient heating options for their homes. By understanding HSPF, professionals can better guide their clients towards systems that optimize energy use and minimize greenhouse gas emissions.
