Keeps freezing We installed a brand new Goodman Condensing Unit, Model #GSX130481, Serial #1304691511 and installed a new coil, Model #96-8W4N-0p/96-8, Serial #M0425130485 (Mortex Brand)in the existing Air Handler. The unit keeps freezing up. Can you give any insight on what might be the problem?

Depends on if your going to stay with the old refrigerent system of R 22 ro upgrade to the new R410A system. I have been upgreading my customers to 410A if the compressor has failed. Replacement of all components recomended on a compressor burn out.

SOURCE: hello, my HVAC is constantly

I'm new at this and I can't tell how old the post is but I'll contribute anyway.
You probably have fixed the problem by now. I wonder what part of the system is freezing up. I don't have a lot of experience but I know you can get frost where there is a restriction in the freon. If the freon line filter near the outside unit has frost on the house side the filter is partially plugged. I have also seen fost on the evaporator (attic "A" coil) when there is a shortage of return air flow. You could have a plugged filter or colapsed return duct, or even an "A" coil with a lot of dust covering and plugging the fins. I guess restrictions in your room air supply registers could cause the problem too. Maybe you have most of the vents closed off to save energy. Just some possibilities.

Goodmans troubleshooting

You don't mention the fan. It is at the top of the condensing unit and should be running whenever the compressor is running. The water is doing the same ob the fan does, removing the heat from the refrigerant . What led you to put water on it?

Sounds like the contactor in the condensing unit is stuck. That is why it will not turn off when the thermostat is satisfied. If the inside air handler is not blowing and the outside condensing unit is running, then this will cause the inside coils to freeze up rather quickly.
The contactor is located in the outside condensing uni in the electrical compartment.
If it is sticking it will need to be replaced.

No you can not use a R-410 air handler with a R-22 condenser unit...the exspansion devices are different as the properties of the refrigerants are enough different that they are not interchangable...
Really your only choice is to replace the whole unit as it sounds like the exspansion valve or the orfice is partially clogged and it makes you constantly freeze up....

Every 1 minute it has a one second surge

Hello Dave,
The first place to start is with the line voltage supplying the condensing unit. Check ALL line voltage connections at the condensing unit, the service disconnect, and the electrical panel box. If you have a weak connection or overheating circuit breaker, it could create these surges.

Don't forget to ensure the filters and coils are clean to keep your system operating at peak performance & efficiency. :-)

It is not freezing up because of the temperature, but because of ice being formed in inside. Either by a blocked condensation duct, or snow due to previous storm.

GE Profile refrigerator temperature problem

refrigerators have 2 coils. the evaporator coil and the condensing coil. one is on the bottom of the fridg and one is on the back or inside behind a false panel. these coils must be kept clean or if the condensing coil cannot reject the heat absorbed by the evaporator, the box temp will stay high and if the evap coil cant absorb heat the box temp stays low running the risk of freezing

What do I do when my A-coil goes out in my Goodman condensing unit? How do you replace it?

You have to be certified in refrigeration. Its a sealed system and you need the correct tools to fix. I'm sorry but you will need a tech to fix that.

Goodman a/c not cooling

It looks like you did make some improvements when you replaced the coil and metering devise. The fact that this system never ran right "out of the box" is suspicious. My first instinct is that the system is either unmatched in size or the whole system is sized incorrectly. Do your Heat gain/Loss calcs and see if it matches close to what is in there, both for the coil and condenser. Secondly double check that the evap you installed is matched the same as the condenser. In some situations the ID coil can be over sized by a 1/2 ton. But that is the only exception and it does not apply to all cases.

If the system is sized and matched correctly, then I would consider the compressor to be the problem.
