A/C Issue's Any Help..?
Purchased a new town home last year, had incorrectly wiring for 3ton unit so they replaced with 2ton.
This year had a tech come out to check
1st one said need to replace TXV and install filter dryer, "Found low suction side, High discharge side. Estimate 900.00
But that's when A/C was blowing hot air..
Some how when the 2nd tech came it worked again and blow cold air. but pressures still incorrect..
Called another tech to come out his story was different.
Pressure H494/Low 105PSI.. Possible leak, incorrect installation to lines which may cause the high and low pressure.. He said the lines might have a kink in it and that's why the pressure is reading that way..
Currently A/C is working but no colder then 69* some area's 75*, but that's when outside temp is 80. When it hit 100 i cannot cool down home below 85*..
My town home is only 1050 sf.. Which one seems most likely issue? Replace TXV or find leak, recharge, then check for bad lines?
