First off thank you for any advice you can give!! I live in Sarasota FL. and need the hole package. My current unit is 31 years old and still going, not strong, but like the little engine that could. My house is 1442sqft, with 14 windows and 3 sliding glass door's.
These are from the top company's 1&2
1) Comfertmaker 18 Seer, 3ton C4A836, FVM4X60
2) Amana ASZ16, 3 ton, variable speed heat pump system with 16 S.E.E.R. rating
Trane XL16i, 3 ton, electric furnace & straight cool system with 17.15 S.E.E.R.
Amana ASX18, 3 ton, variable speed electric furnace & 2-stage straight cool system with 19 S.E.E.R.
Trane XL20i , 3 ton, variable speed electric furnace & 2-stage/ 2- compressors straight cool system with 18.6 S.E.E.R.
Is Comfertmaker better then Amana or Train? The costs are within $ and all include new returns and moving the unit from the attic to the garage. Is there one better then the other, or dose one give more problems then the rest?
