Why is my winter heating bill so much higher than my neighbor's?

✓ Accepted answer

Your mother’s higher heating bill is likely caused by significant heat loss due to poor sealing, inefficient equipment, or a drafty structure that her neighbor’s apartment does not have.

• Check for air leaks: Drafts around windows, doors, and baseboards can increase heating costs by 10 to 20 percent. Use a smoke stick or a simple fan test to identify where cold air is entering the home.
• Inspect the HVAC system: If the furnace or boiler is older than 15 years, it may be operating at 70 to 80 percent efficiency. Scheduling an annual professional inspection can reveal if filters are clogged or if the heat exchanger is failing, which often explains high fuel consumption.
• Review insulation levels: Identical apartments can have different R-values in the attic, walls, or floors. If the property manager does not maintain insulation, adding weatherstripping to interior doors or using draft stoppers at night can make a noticeable difference.
• Verify utility billing details: Ensure the billing meter is accurate and that the heat is not being shared or billed differently due to sub-metering errors. Contact the utility company to request a meter audit if usage spikes suddenly.
• Consider local climate zones: Even in the same building, the orientation of the apartment matters. Units facing north or west often require more energy to maintain 68 degrees Fahrenheit during winter months compared to sunlit units.
