Question about AmcorAire UCHW-H12AF2 Split System Air Conditioner

1 Answer

I have a 24 ton mini split, that has never worked correct. It used to blow cold air, but only for a little while, then it set error codes including p4, and p8. The heat functioned used to work ok. Now it just sets a FC code, or failed compressor. The supplier would not warranty the unit, so I am stuck with a dead ac, and 2000 dollar bill. Is there any hope.

    The P-8 error code means low refrigerant level / reversing valve is stuck.
    Recover the refrigerant from the system, pressurize no more than 150 psi. check for leaks.
    Vacuum the system add fresh refrigerant type: R-410A. If the system is a 2 ton inverter, manufacturer recommended replacing the circuit boards in the power supply.

The blower starts before its warm and it blows cold air for about 30 sec when its shutting down .


When any unit 1st come's on, you'll always have some cold air that's in the ducts that will blow out before you get warm air. If your duct work is uninsulated in a cold basement or crawl space then it will be even more noticeable. When the unit is heating from the Heat Pump mode, it takes a little longer for the gases to get warm enough so you'll fell heat. When it gets cold enough for the unit to switch from heat pump to the gas or electric heat source, you'll get warm air faster. If you have gas heat, some Thermostats have an anticipator setting for the gas valve. If it's set wrong it will effect the on/off cycle of the gas valve.
All duct work in non heated and a/c spaces, including inside walls,above dropped ceilings, in attics and crawl spaces, must be sealed & taped at the seams and joints and then insulated and taped.
Most new construction has solved that problem with insulated duct board, flexible insulated supply's and special tape.
