What is the relationship between temperature and humidity in a furnace?
Humidity is a factor in HVAC performance (and the overall comfort of your home). This is the case in both heating seasons and cooling seasons. In the Ottawa winter, moisture levels drop substantially and that can make your house feel cooler than the thermostat would otherwise indicate. Many modern furnaces are actually built with a humidifier already on board (or can accommodate one being added afterward). Adding humidity to the heating process can help you feel more comfortable without raising the temperature – this saves you on utility bills.
