    If its gas and needs to be replaced,, the new gas furnaces also run on 110 volts,
    It just scares me thinking about people taking such a gamble with their lives when it takes so little to be safe and have it checked out,,

    I had 2 family members found passed away because of a bad furnace,, also their 2 kids, 3 and 5 years old
