Heard Gree Technical Representative is somewhat almost non existent in the USA, only guessing due to market share and overall size the Daikin is superior

Inverters have a hard time meeting the EER2 ratings for the tax credits and it’s not just Daikin. Possibly it may meet state rebates efficiency requirements as those are typically different or may...
