What's the difference? American Standard AC Gold SI vs Silver SI
I'm back with more questions....What's the difference between these two ac units?
American Standard Gold SI is the old Allegiance 13 (14.5 SEER, R-410A, 10-year warranty on compressor, outdoor coil, internal functional parts) and the American Standard Silver SI is the AS 13 (same warranty, same SEER)...at least that's what the brochure from American Standard says.
I originally wanted to replace the outside ac unit, lineset, and evaporator coils, but now I'm thinking that I should replace everything including the furnace.
House: Near downtown Los Angeles, 1430 sqft with insulation R-30 in attic, but zero insulation in walls/floor (crawl space). Double-pane windows. Thinking about insulating walls in the near future.
- Rheem 75K BTU, 80.5 Efficiency, 19-years old and still works well
- Fraser-Jonhston AC unit, probably 10-SEER, 24-years old, 3.5 tons (42 BTU), R-22 Freon
I'm looking for a good American Standard recommendation in the mid-level. This is why I'm thinking either the AS Gold SI or AS Silver SI at 2.5 tons, and matching gas furnace and evap coils.
