Fan on the same time the furnace is on

Hello everyone. I need to know if any of you have the following issue. Our air conditioner fan is coming on at the same time the furnace is on. It doesn't always come on, just sometimes. I just called the factory, and was told this is normal and it is suppose to come on to circulate air and hold down condensation. That does not make sense to me. I should be able to control when the fan comes on. Can anyone confirm this for me?
Thank you!

never heard of that before. Our A/c does not come on with the furnace. I can see no reason for that unless you have heat strips installed in the AC unit. but that also would be independant of the furnace.

This has been addressed several times on this forum. You need to use your thermostat and push the "mode" button till it gets to "fan". Then scroll to "auto". If it is on "high" or "low" the fan will always come on with the furnace.

Peace
