Why Is My Electric Bill So High?
One of the most common questions homeowners ask is, "Is my utility bill normal?" Without data, it's hard to know if a $250 bill in July is standard for your area or a sign of an inefficient AC unit.
Benchmarking Your Usage
This calculator uses data on average energy consumption per square foot across different climate zones to give you a personalized "expected range."
- Mild Climates: Areas like San Diego require less heating and cooling, resulting in lower baselines.
- Extreme Climates: Places like Phoenix or Minneapolis have high energy demands for climate control, pushing the "normal" range higher.
Common Causes of High Bills
If your bill is significantly higher than the estimate, consider checking:
- HVAC Efficiency: Old filters or refrigerant leaks can double cooling costs.
- Insulation: Poor attic insulation lets conditioned air escape.
- Vampire Loads: Electronics plugged in but not used can account for 10% of your bill.
- Water Heating: Set your water heater to 120°F (49°C) to save money without sacrificing comfort.
Frequently Asked Questions
Why is my bill higher in summer/winter?
Heating and cooling (HVAC) typically account for 50% of home energy use. Extreme temperatures force your system to work harder to maintain a comfortable temperature.
What refers to a "Climate Zone"?
Climate zones classify regions by their heating and cooling needs. "Extreme" zones have very hot summers or very cold winters, requiring significantly more energy to keep homes comfortable.
Does unplugging devices really help?
Yes. "Vampire power" from devices in standby mode (like TVs, gaming consoles, and microwaves) can account for 10-20% of your average monthly bill.
