Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.How many sqaure feet is in the home?(14 X 70)(16 x80)? the furnace is designed to work with up to a 4 ton coil.
Expert:  airheatman replied 1 year ago.
You can use anywhere from a 2 ton coil to a 4 ton coil. Do you know what outdoor unit you will be using and also if you will be needing a coil that uses r22 or the new R410A?
