What year was your house built? Do you have a whole-house humidifier? My house was built in the late 1980s. It has decent insulation but not amazing. It still needs a lot of heating when temperatures plunge below -15C. I do not have a whole-house humidifier. I had one with my previous furnace but it had issues with mold in the filter and clogging of the condensate pump.
