possibly serrano i think. i`m no expert and i`m sure other peppers look similar. here is a pic of a serrano i`m growing. compare your to this.
They look like serranos to me. Looks very similar to my plant, along with the peppers.
I know there are multiple strains of Serrano I've never seen but the OP's pic has very pointed pods, see his pic below, so I'm not jumping up and down over your ID.... YMMV
So I was looking for something but found below...Note the Serrano has a rounded point? Not the straight taper of OP's.
