Leave thermostat’s fan switch on “auto” so the fan only runs when the furnace runs. Setting the fan to “on” causes it to run all the time, whether or not heating or cooling is needed.

I disagree with Country B on this one. Keeping the fan running "slow" continuously helps circulate the cool or warm air around the house while using very little electricity.

Maybe power rates are exorbitant in Scotland but in the rest of the civilized world, they're fairly reasonable. ;-)

I tried running the furnace fan with room air conditioner but it seemed to draw warmer air from under the house into the house causing more humidity and making the a/c work harder! So I set a couple fans on the floor in the house to move the cool air around.

It’s generally not necessary to run the furnace fan continuously while the air conditioner is operating. Using the “Auto” fan setting allows the blower to run when the AC is actively cooling, which usually saves electricity and helps control humidity. Running the fan constantly can sometimes redistribute warm air and may increase indoor humidity, especially in humid climates. However, continuous fan operation can improve air circulation and filtration, so it may be useful if your home has uneven temperatures or air-quality concerns.
