1. Would it hurt anything to have the condensate drain line empty into the washing machine drain that empties into the septic system? I didn’t know if the acidic nature of the condensation would have any negative effect on the septic system? The condensate drain currently exits through the basement wall, but come winter I am concerned about it possibly freezing up. (92+ furnace)
2. The line set and condensate drain line exit the basement through a PVC pipe in the cinderblock wall. They used plenty of silicone between the PVC and cinderblock, but where the line set goes through the PVC it is not sealed. Is this left unsealed for a reason? Would it hurt anything if I put a little spray foam insulation in there? Should I just leave it as is?
Why don't you leave it alone and don't worry about freezing a condensate line you describe. So what if some residual water freezes in the winter; it shouldn't cause any problem unless you have some nasty turns and the line is copper.
When you need A/C in the summer I guarantee it will be defrosted.
You would need a PH neutralizer added to your condensate system.
The condensate from my (new) system (heat and cool) is pumped from the basement, to a washtub in my first floor laundry room.
It is permitted by code since (1) there is an air break, and (2) the waste system is all PVC.
I plan to make a cannister, to be filled with marble chips (close to 100% Calcium Carbonate) through which the furnace condensate will drain (out of the bottom) and neutralize the acid.
Oh, I didn't notice.
But with flow of condensate in winter no way could it freeze up anyway since it takes a lot of time to lose enough heat for freezing.

Wow, What overkill for a simple problem unless you cant dump it outside.
