You need to contact your State's LIHEAP agency to find out about the qualifications needed to be eligible for LIHEAP assistance, where one can apply for assistance, and whether such assistance is currently available. 

Please go to http://www.acf.hhs.gov/programs/liheap/grantees/states.html to locate your State's LIHEAP agency to answer your questions.

Being eligible for LIHEAP assistance does not guarantee that you will receive the assistance.  This is depends on how much Federal LIHEAP funds are available for the year.  When the LIHEAP funds are exhausted, LIHEAP grantees can no longer provide Federal help until Congress provides funds for the next Federal Fiscal Year which begins on October 1st of each year.
