Why does my AC turn hot and cold?
If your A/C flip-flops from hot to cold and back again, your expansion valve could be failing. The expansion valve distributes the proper amount of refrigerant to your evaporator. If the valve is blocked, the refrigerant flow could be restricted or could be too unrestricted. Your A/C blows warm air.

Why does my AC keep blowing hot air?
Recently when running the AC, it will randomly begin blowing hot air instead of cold. No matter what I try, the only proven way to get cold air to blow again is to shut the engine off, wait around 5 seconds, then crank back up. After doing this everything seems to work fine for a week or so…then the AC starts blowing hot air again.
