How is the heating season defined in HVAC?

The heating season in HVAC is defined as the time of year when heating is typically required. This period is primarily determined by the average outdoor temperatures that fall below a certain threshold where heating systems must be utilized to maintain comfortable indoor conditions. Essentially, heating systems are activated to respond to external temperatures that necessitate the use of heat to ensure occupant comfort and safety.

During this season, HVAC professionals typically monitor and adjust heating equipment to ensure it operates efficiently, and it is also when utility companies might anticipate increased demand for energy as households and businesses use more heating fuel or electricity. Recognizing this season allows for better energy management, system maintenance, and understanding of climate impacts on building comfort.
