The Weatherization component works to tighten and insulate homes against the elements and to assure the safety of appliances by providing health and safety checks, furnace repair/replacement, refrigerator or freezer replacement, home insulation, minor repairs and client education. To be eligible for Weatherization, clients must be below 200% of the federal poverty level or must have been approved for LIHEAP. Weatherization priority is determined by a state matrix that includes fuel usage and household data.
