Furnace thermostats make life easier and better because they exist. When a furnace thermostat needs to be replaced, it can cause problems with the heating and cooling devices. But don’t sweat it, we’ve got you covered right here.

There are types of furnaces that don’t work with certain types of fan speeds. Most homes have at least two furnaces for two separate functions – one is for down-long furnace units and the other one provides heating to homes. The troubleshooting in these situations depends on switching from one unit to another if the problem can’t be fixed by adjusting it or having a serviceman come fix the problem when needed.

You should not change the set point of the furnace without consulting an experienced professional or turning off power first, making sure not to disable safety controls!
