Heat pumps sold so fast in Maine, the state just upped its target

This is a most excellent place for technology news and articles.
Just had a 48btu unit installed. 2,000 sqft, 3 - 9k wall units, 1 - 18k ducted unit. Operational down to -22 F.
$20,000 and then a $4,300 rebate and later a $2,000 tax credit. Down right affordable. Would have been even less if new ductwork didn't have to be retrofitted.
