Hi everyone! First time here and need to let you know… you guys are great. As a homeowner with little knowledge of HVAC equipment, I’ve learned more in a few hours here than in the previous three days. OK, here is the background:
Right after Christmas, the neighbor’s house burned down due to a faulty furnace. The rest of us became nervous and discovered all of us had defective units. Called a local HVAC firm and had a Trane model TUE080A948 with a TXC042C4HP coil and something called a TXV 10 SEER coil installed (after reading many posts here, I’m assuming the TXV is really just the expansion valve and not the whole coil). This was an upgrade from the original unit due to a remodel project due to be completed in about a month (went from 1450 to 1850 square feet). Anyway, we didn’t have the money to upgrade the condenser and I was due to deploy overseas two days later so couldn’t do much more. Fast forward to now.
I’m now back home, the weather has gotten hot, the system isn’t cooling, and the wife isn’t happy. Not surprising since the old unit is 2 ton and the HVAC contractor calculated we need a 3-1/2 ton. Trane has several different models with various efficiency ratings. So, my questions are:
What model condenser would you guys recommend I go with? Can I get any better performance than 10 SEER without swapping out the six-month old equipment? And finally, do I need to stay with a Trane condenser?
