Brewing a porter, pitched my yeast and started with a 1.056. My air conditioner broke for 1 day and the beer got to about 80 degrees after about 1 1/2 weeks of fermentation. Beer has been sitting at 1.036 for two weeks now. Can I repitch? Or is it needing to be dumped? And if I can repitch, does it need to be transferred to a new bucket first?

No matter what the gravity reads, that beer is done. What was the OG? Was it an extract batch? I doubt repitching will make any difference.
I would start by just swirling the carboy so that the yeast bed breaks up. Leave it for a few days and take another reading. It there is no or little change, then do as Pepi says; make a starter and re-pitch to the same fermenter.
I'd pop the lid to let in some air, then reattach the lid and give fermenter a good shake, to stir things up, wait a day to see if it kicks off again, if not as pepi suggests use a starter.
There's no reason to dump a beer that isn't contaminated. After 1.5 weeks and a trip to 80F, the beer should be done fermenting. And warm temps late in fermentation have little impact on flavor.
You can try stirring up the yeast, but a re-pitch of active yeast is probably worth doing. If you can make a starter that would really help, since the partly fermented beer contains no oxygen.
Transferring is unnecessary, and risky with the residual sugar still present.
