I have an older (1992) 5 ton Carrier and the compressor has imploded.
My tech recommends that I replace the outside unit with a Trane 4TTR4060C and the inside with an Aspen TXV evaporator coil (because it will fit better and pair up easily with the 1 year old gas furnace).
Are these units likely to work well together and be efficient as a pair?
The old unit is R-22 and the lines were run in a big arc in the attic (low at both ends and high in the middle) so he also recommends replacing them with better run lines. Due to the 4 foot tall arc, they may be difficult to flush (burnt oil) to make them ready for 410.
My air return is a 23x24 (annoying size) near the floor (that sings) and he recommended adding a second return in the hall ceiling because of the volume of air flow.
The home is a 1 story 1979 of 2,300 sq ft. It has 4 bedrooms, a high ceiling in the living room and old single pane windows. The insulation is medium at best. I am in Houston, Tx.
I really appreciate any feedback or questions you may have for me to ask!
