Anyone have high level input on furnaces and water heaters? Water heater is ~15 years old, softened water and I expect it to die or leak in the short term ish. I changed the anode when I moved in and it was down to a nub, didn't seem like anyone else ever changed it before.
Furnace is mid efficiency from the 90s, Air Conditioner was added in about 2016. If I replace the furnace does it limit me on the evap coil as far as which furnace brands I can look at?
I assume if I replace the furnace and hot water tank with hi-efficiency/PVC venting, you seal up the B-Vent, run PVC through sidewall... I suspect I could leverage the current air intake for the furnace and replace this with concentric vent PVC?
