It sounds simple, but this algorithm will very quickly break both your ac and heating units. You want a PID controller in there (in some cases you might get away with just PI, but that needs analysis of the specific case) Ideally of course you'd want to model the exact energy loss curve of the specific building you're in but nobody really does that. The best part is of course that a PID controller sounds complicated, but the simplest one is actually just around 15 lines of code.
