The most common APS billing errors include incorrect meter readings, wrong rate plan applied, estimated reads that are too high, and charges for services you didn't request. Meter malfunctions are rare but can cause persistent overcharges that go unnoticed for months.
Compare your current bill to the same month last year. Check that your rate plan matches what you signed up for. Verify the meter reading on your bill matches your actual meter. Calculate your cost per kWh by dividing total charges by total usage — if it's significantly above your area average, investigate further.
If you believe your APS bill is incorrect, contact customer service with your account number, the specific charge in question, and your reasoning. Request a meter test if you suspect a faulty meter. You can also file a complaint with your state public utility commission if APS doesn't resolve the issue.
