I am installing a split system Envision 2 stage w/desuperheater. My goal is to utilize the power companies "dual fuel" rate. That's why I bought the split system.


I have heard that the indoor coil has to be matched to the HP, and an ARI number needs to be entered in at tax time to get the 30% deduction from uncle sam.

My question is, Can anybody reply with details on this?

I quoted a 3 ton coil from WF, and they want $700+ for an A coil. There's gotta be a cheaper option.

Thanks in advance.
