so today with the temp change and some cooking, the AC seemed to overheat and the overflow pan had about 1/4" of water on one side

with the cold air coming in tonight i figured i could shut it off and run the heat tomorrow. is that going to run into any issues that would be causing the backup? is there going to be condensation to back up? if the coil is frozen, would the heating unit affect anything?

Pour some Clorox down the drain pipe

I wouldn't think so. The placement of the cold and hot air is reversed in your system when you run the heat. So the cold air will be at the outdoor unit.

You have the typical outside unit that looks like a square radiator, and an A frame or something inside? Like another poster said...do you have a heat pump unit? It's likely that you don't, and if that's true, then the heat portion won't affect the cooling issue.

Also, note that water backing up is a clogged drain pipe issue, but it doesn't typically lead to frozen over coils. Frozen coils on the A frame is from not enough air flow getting through from dirty fins or from various other reasons.

there is a unit outside but i think that's just to blow air around. the real unit is inside in the attic

i do not believe so

yeah i figure that's the most likely culprit. i just didn't want to mess with it in the heat today and it will be much better tomorrow when it cools down

Well, you should be fine. If something were to freeze up when running the heat, it would be your outdoor coil. Everything inside the house would be pushing warm air.

They all will have issues over time
But from what I’ve heard “they” say Goodman is on the cheaper end and not as long lasting.
I have no data to support this statement

I had a Goodman unit at my old house and I can say yes it is trash. Three evaporator coil leaks in less than 5 years.

ETA: It was a new construction in a spec home neighborhood.
I think they were putting Goodmans in every house and it wasn't because of their reliability.

It's probably worth a spin to pass through a few new, low to mid priced, neighborhood construction homes and check out the AC type the contractors are installing and NOT choose that one.
