Many homeowners see 10-30% lower energy bills (sometimes more) plus thousands of dollars in direct rebates. A $8,000 rebate + $800/year savings pays back very quickly.
Yes – in most cases you can stack with utility rebates, federal tax credits (where still available), and other programs.
The program may expand to moderate-income households later. Several utilities (Ameren, Nicor, Peoples Gas) also offer insulation rebates right now.
Most common types – blown-in, batt, spray foam, rigid board – as long as the overall project meets the energy savings requirement.
