What is the difference between the pipe types you stock?

PVC is used for condensate drains and for venting high-efficiency furnaces. Black iron and CSST are gas. Conduit protects electrical. They are not interchangeable and each has its own code requirements.

Can I use PVC for a furnace flue?

Only on a condensing (90%+) furnace that is designed for it, and only the pipe schedule and material the manufacturer specifies. An 80% furnace vents into metal B-vent, never plastic - the flue gas is far too hot.

What size condensate drain line?

3/4 inch is the residential standard. Give it a consistent slope, put a cleanout at the top so it can be vacuumed, and fit a trap where the equipment calls for one.

Who can run gas pipe?

In Texas a homeowner may work on their own home under the homeowner exemption; that does not extend to doing it for someone else. Gas work is unforgiving and leak testing is not optional. If you are unsure, this is one to hand off.
