Got a question about central air issues
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

Your condensate line is clogged

do you have a furnace or a heat pump?

re: Got a question about central air issues
i understand that. i was just curious if running the heat would cause condensation like the air does

re: Got a question about central air issues
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

re: Got a question about central air issues
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.
