I had my York 5 ton R22 replaced with a new 5 ton Byrant 13 seer 410A about 2 weeks ago, and the ac guys had installed a TXV in the attic on the evaporator coil. However, the ac worked ok for about a day and then the inside started to warm up.
I called them back and they said the evaporator coil was leaking, and I had that replaced by another ac company as the first company was asking to much.
Still it is not cooling below 81 degrees and ac guys say it's because it's over 100 degrees outside that's why.
Well, it use to cool down to 72 degrees before in the hot summer with over 100 degrees, so I think they are trying to evade fixing the problem.
Can any one help or have any suggestion as to what might be wrong?
