Should utility companies be required to help residents identify efficiency issues in older homes?

An inspection of a 1,700-square-foot home on the city's west side revealed that structural issues were causing excessive electricity usage during winter months. AES Indiana confirmed the home's failure to retain treated air was the primary driver for high utility costs.

Why it matters

Understanding structural energy efficiency is critical for homeowners in older buildings facing high utility bills. The findings highlight how aging infrastructure often fails to maintain thermal regulation, leading to significant power waste.

The 126-year-old home uses 13,000 kilowatts during winter compared to summer usage of 2,000 to 3,000 kilowatts. The resident recently paid $4,600 to restore service and is now on a 36-month payment plan.

The players

AES Indiana

This is the primary electric utility provider serving the Indianapolis area.

Indiana Community Action Association

This organization connects residents to energy assistance and safety improvement programs.

The details

The utility assessment identified disconnected basement ductwork and an attic air gap that prevent the 1,700-square-foot home from retaining treated air. While the thermostat is set to 68 degrees, the structural defects contribute to the high electricity demand.

I-Team investigators visited the residence on Sept. 14, 2026.
AES Indiana conducted the formal energy efficiency assessment on Sept. 30, 2026.
October 2026 is designated as Energy Awareness Month.

Market Landscape

The implementation of levelized billing reflects a broader industry shift toward standardized consumer protection and billing predictability. This move aligns with state mandates designed to help utility customers manage seasonal volatility in energy demand.

Homeowners in older properties may face high utility costs due to hidden structural leaks rather than billing errors. Residents should monitor their winter versus summer usage to identify potential efficiency gaps that could qualify for assistance programs.

The takeaway

Older homes require specific maintenance, such as attic sealing and duct repair, to improve overall energy efficiency. Conducting an energy audit can help residents identify these structural issues and lower their monthly energy expenditures.
