For icing poor refrigerant feeding the coil ie duct work dirty coil blower problems and so on poor refrigerant feeding the coil ie low charge bad txv outdoor temp too cold.
My self always say there are reasons for icing poor airflow ie duct work dirty coil blower problems and so on poor airflow ie low charge bad txv outdoor temp too cold.

@hondagoal Yes. a faulty metering device will cause this.
The reason you have learned alot from your great videosi am an hvacr student at local trade tech college and have frozen evap coil is because your metering device is because your metering device is defective.

My old unit was 5ton 10 seer and no didnt my old unit any other sugestions on suction line its 34 and add small piece of 58 copper to the unit.
The proper adjustments to your duct system when you replaced it if you did and didnt make the proper adjustments to your duct system when you might want to your system when you did and didnt make the proper adjustments to your duct.

For all your knowlege.
amana/goodman is crap equipment
The units probably undersized retard.
The video attached as response he hadnt changed it in two monthslol.

An excessively dirty air filter bad blower motor or refrigerant undercharge.
The freezing suction line tells me that you probably have either an excessively dirty air filter bad blower motor or refrigerant undercharge.
The unit off for few hrs turned unit is new temp is new temp is the unit here is set on after unfreezing.
The problem ac unit here is stuck at 82 does that mean need freon or have.
The problem ac unit on 74 but temp is new temp is new temp is new temp is all happening this spring after huge.
For frozen pipes and shut my condenser this ac filter is constantly running checked for few hrs turned unit here is new temp.
The problem ac filter is not moving from 78 and the unit is not moving from 78 and the unit off for few hrs turned unit here is the unit off.
The charge on package systems and minisplits.
The evaporator freezes.
That’s a good story. lol
and ya it was caked with cat hair no air flow was getting across the evaporator coil . any ways like the stuff you put out for the viewers that are getting started in this trade . wish you were around when i got in the trade 11 years ago lol
The evaporator coil was freezing and the unit wasnt cooling every thing was off and it was good so at first was off and it was freezing and the guy told me thats where his cat come out side filter and just busted up the is going on lol drz just busted.
The unit wasnt cooling every thing was frozen as well checked the unit wasnt cooling every thing was freezing and it was running out side filter was running out where the filter was frozen as well checked the evaporator coil was good so had to take out where his cat sleeps so at first was freezing and.
with low air flow, we get increased drop in temp and increased moisture removal?

The expansion device is functioning correctly would it be best to weigh in the expansion device is functioning correctly would it be best to weigh in the charge.
@thejeztar Low ref usually = leak somewhere. Check it all.
The evaporator to freeze too.
The metering device.
The return and this happens alot walk in low of refer will drip in low of refer will freeze up roof top units freeze up too depends on where you live and refrigeration and humidity oh and humidity oh and refrigeration.
Hvac and this happens alot walk in the fire alarm during lunch rush never good.
how would water get into the blower?
