The bill is steadily high, not just one seasonal spike, and always-on appliance use may be part of the baseline.
A refrigerator runs every day, so small efficiency issues can become a monthly baseline cost. Age, location, coil dust, and door seals matter more than one short appliance session.
Check first
Check whether the refrigerator or freezer is old, in a hot garage, or overfilled.
Look for damaged door seals or doors that do not close cleanly.
Clean coils if the model has accessible coils.
Compare baseline kWh in mild months before and after changes.
Practical savings moves
Improve airflow around the unit.
Set temperatures to practical food-safe ranges without overcooling.
Fix door seal issues that make the compressor cycle more often.
Compare the refrigerator with other always-on loads before replacing it.
Avoid these mistakes
Do not use nameplate peak watts as 24-hour continuous usage.
Do not blame the refrigerator for a sudden weather-driven bill spike.
Do not ignore a separate freezer or second fridge.
