Factors Causing Variation

• Heating system efficiency: Older furnaces (60-70% AFUE) vs. modern condensing units (90-98%).
• Thermostat settings: Each degree lower saves 1-3%.
• Weather severity: Polar vortex events spike usage 20-40%.
• Rate structure: Utility delivery charges + commodity cost (varies monthly).
