Wall switch wiring
I was installing sheetrock in my garage and had to disconnect the wires to my heater blower. It has a wall switch installed and I turned the switch off and did a voltage check. The black was plenty hot. Discovered that they installed the switch on the common or white wire. I changed it out and installed the switch in the black. So I checked the lighting switches and they are the same. I am thinking I should correct the light switches too. Am I overly concerned?

If there are only black wires and its not a switch loop the blacks should be the switched wires. Years ago my Dad had a handyman that was fond of switching the whites, ruined a pair of pliers over that one.
