Why does my central heater smell of urine?

Whenever our high-efficiency heater runs, I smell urine. Why would that be?

Our house is a 1970's one-story ranch build on a concrete slab. We've owned it since August. The home inspector didn't see any signs of rodent activity, neither did the pest inspector, and we've had an exterminator out since then to spray for bugs and inspect once more. I'm pretty sure if we had sudden rodent activity, the cat and/or the dogs would be giving some kind of indication, wouldn't they? Also, we didn't have this trouble with the A/C, which we ran in the summer, this being New Mexico. We don't run the heater as often, this being New Mexico, but yeah, when we do, it reeks! We've changed the filter, and that didn't help. We've looked for pet accidents with a blue light around the air intake and found nothing. We've checked the carpeting all over the house and found no pet mistakes anywhere. My guy says that he smells "a little bit of something" but to me it stinks to high heaven.
The only difference between the summer and now is that the ceiling fans have been turned off because they need cleaning. Also, we had to replace the condensation pump (this was after the smell started) because the old one blew up all over the utility closet -- water everywhere!).
This could be unrelated, but since late fall, but I've developed a dry cough, ended up in the ER with said cough, and am now on an inhaled steroid (I have asthma).
