I am adding a second heat and a/c unit due to house remodel. Is it cost effective to make the second unit electric heat? The main unit is natural gas.

according to were you live and the differance in the cost ,,,right now where I live electric is right much cheaper,,but prob. won`t stay that way,,,,it is somewhat cheaper initial cost of the equipment electric is cheaper to buy and takes less to install,with elect furnace there is a lot less to go wrong,,
