just an FYI, The High Efficiency Electric Home Rebate Act (HEEHRA) was included in the Inflation Reduction Act that was passed last year and it includes direct rebates for low and moderate income homes for electrification projects for your home. Some of the rebates include heat pump HVAC and weatherization (sealing leaks, insulation, etc., as someone mentioned below).

I don't think full details for the plan/funding are expected until mid to late 2023, but might be worth it to utilize that program if you qualify.

I've been checking this website for info and updates. Hope this helps!
