New construction. We've got two AC compressors outside - a 3 ton and a 2 ton (I think). Big one cools the downstairs, little one the upstairs. Rather than running two different sized suction lines for the two differently sized compressors, they installed both with 3/4" suction lines. According to the manuals that is the appropriate size for the smaller unit, but too small for the larger unit. They offered to rip everything out and redo it (massive stucco and drywall damage) or install a TXV valve (I think) that is supposed to sense the temperature in the suction line and increase or decrease the volume in the liquid line accordingly. We opted for the latter solution and received another year on our warranty. Is that setup going to work? Or are we going to have trouble down the line?
