I don't throw out soil. As long as it's not bug or fungus infested, with proper amending it can last for a long time. Potting up is a good key to health.
You don't need to replace the soil, just scrape off the top 1/2 inch of soil if it starts to develop a white residue and top that off with new soil. Pothos like being root bound, all new soil can actually encourage root rot, so you don't want to do this too often, once a year is plenty. The real key is to just water lightly (1/2 cup water is plenty) once a week, on a schedule, and stick to it. Remove ropey looking vines and yellow leaves and you're good. As long as your plant looks happy, you don't need to fiddle with it. Less is more with pothos. If your soil is leaching out with watering, you're probably using too much water, or too much water pressure. OTOH if your plant is healthy enough, do what makes you happy.
Our house is full of them. I clone them by taking cuttings and just dropping them into mason jars full of water. The plants can almost live forever just like that. Sometimes then I will take and plant those in soil. Voila.

Another is "Mother-in-law-Tongue" I forget the Latin name.
The Dracaena is also a hardy indoor companion.
While I like my friendly houseplants, I have not ran central heating over the last few years. They all tend to drop Dead in the Freeze.
