Window Condensation - New Home
This is my first time owning a brand new built house and now that the temps in Ottawa are dipping below -20C I'm getting condensation on windows. I thought the humidity levels needed to be between 40-60% because of the hardwood flooring to avoid issues like cracking. My furnace has a humidifier with a little dial on it, it's currently set to between 30-40% (no numbers just a range between 10-75%) and internal humidity level is currently 37%. I do have an HRV system and tbh it's been off, I just realized this should be on during the winter, correct? (again never owned a new house, excuse my stupidity here). There are three settings, Econo, Ventilation and 20 min/hr, which should I put it on? I just worry about mold/mildew in the house with two babies but also worry about the hardwood floors. Any help would be appreciated.
