    I installed a furnace and A/C in Dec a few years back and got a call in early June to check the A/c it would cool a while and then not so good. Check it and found that the metal plate at the top of the A coil had blown off and was laying inside the evap cab. All the air was blowing straight up through the top of the coil. That was a first for me.

    1 mismatched units, 3 ton outdoor 4 ton indoor, ok if blower dialed in correctly, 2 - 2 stage condenser, indoor section has to be configured to match in board during installation, unit is rated for 70*F outdoor, below 82*F outdoor the unit should remain in 1st stage, low ambient control kit recommended

    indoor manual -

    again, speculation is nice but the factory manuals are the Bible for any given unit

    I know my 20 k window AC evaporator ices up after a while when it's <70 outside. But it's likely a midge low on R-22, I picked it up used 28 years ago at a yard sale. Only cleaned it and replaced worn switch. Some Vornado?? unit.
