Seasons
HVAC calls follow the weather, so there are two busy seasons. Summer is AC season: July and August usually bring the most cooling demand (ACHR News). Fall and winter are heating season, when people turn their furnaces on after months off and some of them break. Truck data from Samsara, covering 65 million HVAC service trips from September 2023 to June 2025, found that October was the busiest month of the year, not July, with a dip every September. A heat wave can push calls up fast: during the June 22-25, 2025 heat wave, HVAC techs in Maine made 374 percent more trips per truck than in June the year before (Samsara). Spring and fall are quieter and are mostly tune-ups and planned replacements. Where you are matters too: about 88 percent of US homes use AC, 93 percent in the South and 92 percent in the Midwest, but only 73 percent in the West (EIA, 2020 survey). Hot states get busy in summer and cold states get busy in winter.
