I thought I will take a moment to provide some explanation and let you decide if you are hearing an improvement or not. The electrical power usage at your house is given by:
P = 1/2 x Vp x Ip x Cos (theta) = Vrms x Irms x Cos (theta) Watts
where Vp is the peak voltage in volts
Ip is the peak current in amperes Vrms is the voltage in volts
Irms is the root-mean square current in amperes
theta is the phase angle between the current and voltage
(https://en.wikipedia.org/wiki/Electric_power)
If theta = 0 degree, you get the maximum power with Cos (theta) = 1. If theta > 0 degree, you get something less than max power which is the situation in practice. If you have induction motors, and capacitive loads, theta is going to be >0 degrees.
If there is more inductive reactance, then one can balance that by adding capacitive reactance to the supply. I can only assume that in your house, there is such a large inductive reactance, by adding a simple capacitor to the one of the outlets, you were able to reduce the phase angle so that you get more real power instead of reactive power. This improves the overall efficiency of power delivered to your house.
There are even better solutions if you want to pursue in that direction. Please check the link below for details:https://selinc.com/mktg/130175/?gclid=Cj0KCQjwsuP5BRCoARIsAPtX_wEjRXOp_O-Rofk3TSgimqr0wc272Hp9SfNU_s...
Good luck!
