Can adding inductive load really reduce mains power consumption?
Power companies just bill you for the real power consumed. In fact, the companies are the real ones interested in compensate these unmatched ends with users. Reactive power is stored in parasitic inductances or capacitances and then returned to the grid, so the reason power companies don't like this to happen is that they are not using effectively all power they produce. Nevertheless, although it is not usual for the power companies to adjust domestic connections, it is more frequent on industrial ones. 

Therefore and simplifying, you should not worry about matching your connection since you will appreciate no change on your bill.
