I know nothing here, so this is heavily a question. I ask because I have a heat pump for cooling/heating, but the furnace is the blower. I thought when the fan ran, it pulled from the outdoor intake which is in a very different location from the actual heat pump coils. Thoughts?

The air handler uses inside air only. The compressor heat pump is outside and either runs its cycle strictly on outside air
