Quick answers

Steam, evaporative, or ultrasonic whole-house humidifier?

Steam is the most powerful and works regardless of furnace runtime. Evaporative needs furnace airflow. Ultrasonic mineralizes furniture white. For large or tight homes, steam wins.

Can I install a whole-house steam humidifier myself?

If you are comfortable with 240V wiring, plumbing, and HVAC ductwork, yes. Most owners pay a pro for safety and warranty. Expect 400 to 800 dollars in labor.
