2 PVC Pipes running from unit to basement
OK. These  have nothing to do with and no connection to the AC compressor, which makes a lot more sense than the original question with no outside picture.

Flex pipe is probably not an option - if it IS an option it needs to be a type specifically approved by the furnace manufacturer.

While direct vent exhaust is relatively cool, so it can be run in plastic pipe, it is still quite deadly due to the carbon monoxide it contains, and you do not want to be casual about how it's handled, or you and your family won't wake up some day. It happens.

You might well plot out a different route for the pipes that is less inconvenient, but be sure it fits the manufacturer's requirements for the intake/vent system (or have it done, or checked, by your heating contractor.)
