Have you installed on of those fine particle air filters that lower flow?
I've played with different levels of filtration from the meshy blue cheapos to the high end 3M ones. The cheapos hold out longer, the expensive ones last about 3 weeks. With two very furry dogs and a cat in the house, I settled on midgrade and change monthly - they're usually pretty full.
Wife likes to close off all the registers in the house except the bedrooms at the farthest end of the runs. Doesn't seem to help anything IMO but she insists it does and continues to do it. I added a heat register in the well room a while ago to counter that. So far two days in the extra return opening seems to be doing the trick.
Of course there's CO detectors in the house. One in the basement at the bottom of the stairwell where natural air currents would be passing upwards and another in the hallway by the bedrooms.
