I got two price quotes for a Carrier 5 ton Infinity AC/Heater/Air Purifier/Controller. The only difference in bids was in the evaporative coil
Company X (which I talked to first) quoted with a Puron, 5 ton M#CNPVT6024ACA.
Company Y, which was cheaper, quoted with an ADP PT9660C21 coil which they claim is a better coil from both an application perspective, cost, and quality. He stated I was tight on space with the Air Purifier (it's installed in the garage) and the coil he's putting in is a high-efficiency coil and more expensive coil.
Are there any pro's & con's? Is Company Y's claim true?
