Make sure that your family is safe by checking that your air conditioning unit is operating correctly. If not operating correctly then you can inadvertently add harmful CO2 into your home.

Not only has the furnace been fired up, but we may have added portable kerosene or propane heaters in our garage, or wood stoves in the family room. With these new heat sources come additional precautions and safety concerns.
