There is a really gross smell in my car for some reason

Lately, I have been noticing that there is a really gross smell in my car.

I only notice it whenever I turn on the heating system, though.

This would be a plus if it were in the middle of the summer, but since it’s the middle of the winter and the temperatures around here are freezing cold, I am always turning on the heating system. As a matter of fact, every single time I get into the car, the first thing I do is turn the heating system on full blast. The temperatures where we live have been in the 20s and the teens for the past month, and it doesn’t seem like it’s gonna start heating up around here anytime soon. According to the weatherman on our local new station, this has been one of the coldest winters on record for years. Anyway, I can’t exactly go without my heating system in my car until the weather starts heating up. It’s just too cold for that right now. I did some research online about what could be causing the smell issue in the car, but I can’t really find much of anything. My problem now is that I don’t know whether I should take the car to a mechanic for them to check out the heating system, or to an HVAC technician. It seems as if either one of these professionals would be able to fix the heating problem, but I don’t know which one would be better. I guess it doesn’t really matter, as long as I get the heating fixed!
