What LG&E offers
- Residential rebates are for qualified ENERGY STAR equipment such as central air conditioners, heat pumps, furnaces and heat pump water heaters. Insulation isn't on the list.1
- WeCare is an education and weatherization program for income-qualified customers, at no additional cost. It includes a home energy audit, and in some cases weatherization products such as insulation and duct sealing may be installed.2
And the federal tax credit applies only to improvements made through December 31, 2025.4

Remove old insulation when it's damaged by fire, water or pests, or is hazardous. Otherwise, add on top.5 Nationally, removal is $1 to $2 per square foot and full replacement $2 to $6.5 If the old fill looks like vermiculite, stop:
Where the money goes furthest
- Air sealing around top plates, plumbing and wiring penetrations and recessed lights before insulating ($350 to $3,000 nationally).5
- Venting exhausts outdoors. Fans that exhaust into the attic must be vented outside before new insulation goes in.5
- Baffles at the soffits, so insulation doesn't block airflow ($2 to $3 each).5
- Insulation to the recommended level: R-49 to R-60 in zones 4A/4B through 8, per ENERGY STAR.7
