I am going to replace 2 evaporative coolers with a 3 ton and a 4 ton ac split units
Which includes swapping out the old furnaces. I have been given 2 choices amana 16 seer
2 speed compressor of 14 seer trane with 1 speed compressor. Which is best?

What were the bid costs?

Trane and Amana both make fine units.

What kind of furnaces are you getting?
