Guy says the government set up the heat pump rebate program without giving a heads-up to manufacturers, so in wanting to get in on it for all those new sales, they scrambled and shipped garbage. He's had physically broken parts shipped to him for repairs. He figures even for all the troubles he's seen, there's still all kinds of time-bombs out there, waiting to break down for stupid reasons.
He says it will be at least Monday, maybe Wednesday before we can even find out what the next step will be.
