As North Carolina enters the heating season, a new analysis from Comfort First Heating & Cooling reveals that about two-thirds of Sanford's normal outdoor-temperature heating demand occurs after Christmas. The study, based on the 1991-2020 U.S. Climate Normals, found that the period from December 26 to June 30 accounts for 64.4% of the normal July-June heating-degree-day total at the Sanford 8 NE weather station, compared with just 19.6% before December.
The findings carry implications for how homeowners plan for winter heating. Because the majority of heating demand historically falls after the holidays, residents may need to prepare for extended heating use well into the new year rather than focusing solely on the weeks leading up to Christmas. The analysis shows that Sanford's after-Christmas window has 3.28 times as much normal heating demand as its before-December window, and even after adjusting for the different window lengths, the after-Christmas period still has 2.69 times the heating demand per calendar day.
"Sanford's figures put the seasonal calendar in perspective," said Adam Hagen, general manager at Comfort First Heating & Cooling. "About two-thirds of the normal outdoor-temperature heating demand falls after Christmas. Homeowners can keep that longer view in mind when planning around the holidays, while remembering that the weather in an individual winter can differ from the historical pattern."
The pattern is not unique to Sanford. Raleigh-Durham International Airport shows a similar distribution, with 65.5% of its normal heating demand after Christmas and 18.6% before December. Across all 48 qualified stations in the study, the median after-Christmas share is 64.9%, and every station has a larger after-Christmas share than before-December share. The study calculated the shares using published daily heating-degree-day normals and a fixed July 1-June 30 cycle.
For residents and businesses in the region, the results suggest that heating systems should be maintained and ready for prolonged use after the holiday season. Comfort First Heating & Cooling, which provides HVAC services in Sanford and the Triangle, emphasizes that the historical normals describe typical outdoor-temperature heating demand, not a forecast for any specific winter. The company notes that individual winters can vary, and the analysis does not predict energy use, bills, or equipment performance.
