A furnace technician must be called in to evaluate the heating system’s entire status and act accordingly on the findings. Prevention is the best cure; Alonzy suggests asking your contractor about setting up CO sensors at strategic locations in the house, such as the bedroom.
The furnace heat exchanger itself will have to be checked for cracks, as CO can seep out from them when the machine is running. A Toledo furnace installation expert can recommend a replacement if the testing showed evidence of potential CO generation. The replacement furnace may make a difference if the current machine has logged several years.
