FAIRFIELD — Advice on ways to save on home energy bills will be the topic of a Wednesday program at the town’s Bigelow Center for Senior Activities.

Representatives from Home Energy Solutions will lead the free program, starting at 11:15 a.m., at the center, 100 Mona Terrace.

Free help is available through the Home Energy Solutions’ Income Eligible Program, which will dispatch a technician to perform diagnostic testing on a home or apartment to determine the best ways to save energy. Then, with the resident’s permission, the technician will make on-the-spot improvements, such as sealing drafty doors, windows, ducts and other leaks. The technician also will inspect heating and cooling systems and install energy-saving light bulbs and devices to reduce hot water use.

In addition, the technician will be able to determine if a home qualifies insulation and Energy Star appliance upgrades.

If a resident’s income exceeds the limit for free help, the services available for a $99 fee.

Register for the program by calling 203-256-3166.
