I have purchased Andersen Sash Balance, R18/1337, /1327, /1331 in the past. it seems to be for the right side of the window. Is there equivalent for the lest side?

Thanks for posting. The 24-R18-1337 is non-handed, meaning it should work on both sides of the sash. Let me know if you have further questions.
