For those who meet a 7 year payback
If there is a mandate,
costs increase ~ $660 M a year
$16.5 B over 25 years
55 % of Multifamily households would receive a window unit heat pump
Saving an average of $2,230 per household upgrade
Subsidized heat pumps can be paid back with energy savings in < 7 years
Will choose weatherization if
Will choose if bills would increase without repairs and weatherization
Annual savings are not even to payback costs in < 7 years
*increasing subsidy amount can shrink this group
Heat pumps increase energy bill
Should this group be exempt from mandate?
