I live in Nj and have had a new Carrier Infinity (24ANA136) 3 ton installed. I was quoted $10,400 for the above unit plus matching CNPVP4221 (airhandler/coil) and 58MVC080 Infinity Furnace.
Also included in the price was Infinity control and Aprilaire 600 Humidifier.
I now found that instead of CNPVP4221, they have installed a CNPVP4821 !! What could be reason? Am I going to lose the high efficiency that I paid for?
They sent me the Certification statement from Carrier for tax credit but it shows the matching indoor model 4221!!
What should I do now. Please advise.
