Hello, Weare needing to replace a 22-year-old geothermal unit in a home We have been in now for a year. So We only are replacing the unit itself and have come down to two companies but their products are not the same. That's where I need help. One bid is for a Geocomfort YT048 install price(install price 1$11.500) The other unit is a climatemaster Install price (TXV-22 Tranquility System - $ 13,900.00) Do you know the better machine I have tried looking up but I cant tell which is the better model
