Since the start of the year 2015, we have replaced our conventional refrigerator to the inverter type fridge. Likewise we changed our regular window type airconditioning unit to a split type inverter.
Guess what after a few months of use, i have been consistently saving about 2k pesos a month. I think in about 2 to 3 years time, the savings on electricity will pay for the cost of the inverter appliances.
We got the Panasonic inverter refrigerator.
We got the split type inverter aircon Koppel.
We will know further if maintenance cost will outweigh the electricity savings.
