I want to install a smart thermostat that needs the C wire. I have looked at a bunch of posts already but would like someone to review this wiring in my thermostat and furnace as the blue wire is hooked up to the RC terminal in the thermostat and I also have the R terminal hooked up. The wiring was done before I bought my house and I’ve never had issues with the heating or cooling.

Any help would be greatly appreciated!
