Residential rebates for home insulation
and air sealing

Properly insulating and air-sealing your home can significantly reduce heating and cooling costs. It cuts off the drafts and makes your home warmer in winter and cooler in summer.

Rebates for home insulation and air sealing vary depending on your utility provider. Look in the table below for links to information about home insulation rebates.
