The most common reason for a high TECO Energy bill is seasonal temperature changes. Heating and cooling account for the largest share of residential electricity use. Compare your bill to the same month last year — if usage is similar, the increase may be due to a rate change rather than higher consumption.
A malfunctioning HVAC system, water heater, or refrigerator can silently drive up your TECO Energy bill. Poor insulation, air leaks, and old windows also increase energy waste. If your usage has increased but your habits haven't changed, consider having your HVAC system inspected and checking for air leaks.
TECO Energy rate increases take effect periodically and can raise your bill even with the same usage. Check if you were switched to a different rate plan. Also verify your meter reading — estimated reads can cause temporary spikes. Use our free sanity check to see if your rate is typical for TECO Energy customers.
