Unexplainably high energy bills — San Francisco, California
A sudden spike in energy bills without a change in habits usually points to an inefficient HVAC system, poor insulation, or an electrical issue. Common culprits include a dirty furnace filter, refrigerant leak, faulty thermostat, aging water heater, or air leaks around windows and doors. An HVAC technician can perform an efficiency audit, clean or tune up your system, seal ductwork, and recommend upgrades that pay for themselves in lower bills.
Why this is common in San Francisco
The cool, foggy maritime climate means central AC is rare and rarely needed, so HVAC work centers on heating efficiency, ventilation, and increasingly heat-pump retrofits driven by Title 24 energy rules. Older homes often have undersized or outdated heating systems requiring careful upgrades.
