Homeowners can apply for home insulation grants from the Low Income Home Energy Assistance Program, from financial programs run by property-assessed clean energy programs and from local utilities companies, according to SFGate. Improving home insulation can result in significant savings on heating and cooling bills.
The LIHEAP program, which is run by the Office of Community Services of the U.S. Department of Health and Human Services, provides federally funded grants to help with home weatherization. The program also helps low-income households deal with energy crises and bills, states the Office of Community Services.
PACE programs run out of the U.S. Department of Energy help fund energy-related improvements such as home insulation to private property, funneling the money through local or state governments or through assessment and local improvement districts. While the governmental authorities pay the initial cost of the improvements, the property owners are expected to pay back the funds over time, as the Department of Energy explains.
Many local public utilities offer grants to their customers to upgrade their homes' insulation. The Residential Rehabilitation and Energy Efficient Grant program offered by the public utilities company in Anaheim, California, sends inspectors to customers' homes to advise on energy efficiency and provides grants of up to $5,000, as of 2015, to improve home insulation or make other energy-efficient upgrades to the home, as SFGate notes.
