Will HVAC installers be trained on them, or will they continue to size them for AC load and as a result install systems that are unable to heat below 25F (-5C). The heat pump itself of course can provide heat down to -20F/-25C but it cannot provide enough heat for the climate and so you spend most of the year using the backup heating system (or your house is dangerously cold)
My installer was certified. It was installed right and works well - until the temperature gets to 25F and it just isn’t large enough to keep up. This is a sales problem and a larger unit would be more expensive so they didn’t offer it to me.

What I recommend doing is finding an installer who is certified by the manufacturer; they tend to be trained to do it right.

I’d provide that feedback. They need to hear it.
