A. The Heat Pump takes the heat from the home and releases it outside in the summer to cool the home. In the winter it removes the heat in the outdoor air and releases it inside to warm the home. A furnace only produces heat by burning a fuel or using electric and also moves the air inside.

A. A humidifier is only used in the heating mode to add humidity to the home as the house dries out. Your body evaporates moisture off your skin when it is dry inside, so you feel warmer at a cooler temperature when the humidity is kept at a higher level. If the house gets too dry you will start to have more damage to your wood trim and furniture. Also when the humidity gets too low you can experience more adverse health issues. In the summer when the humidity level is high your air conditioner works to remove the excess humidity in your home.
