The home was vacant, on vacation, or lightly used, but the utility bill still had meaningful electric, water, sewer, or fixed charges.
An empty home can still use energy and water. HVAC protection settings, refrigerators, pumps, security devices, leaks, minimum bills, and fixed fees can keep the bill from reaching zero.
Check first
Find fixed customer, base, sewer, stormwater, trash, and minimum charges.
Check HVAC settings, refrigerator, freezer, sump pump, pool pump, and security loads.
Look for water meter movement when fixtures should be off.
Check for estimated reads or long billing periods while the home was vacant.
Practical savings moves
Set safe thermostat and equipment schedules for vacancy.
Fix leaks quickly if water moves while the home is empty.
Use appliance math for always-on loads before expecting a near-zero bill.
Compare vacant months with the fixed-fee floor.
Avoid these mistakes
Do not expect a utility bill to be zero when fixed fees remain.
Do not turn off protective equipment that prevents damage.
Do not ignore a water bill at an empty home because leaks can continue unnoticed.
