When I moved into my townhouse we were told we must put an exhaust fan into the basement washroom. We had someone do this and since then we have had dryer lint come thru the vent.
We have also noticed that we can only heat one side of the house. Only half our vents give full heat. Could these issues be related?

It's mostly a guess based on the minimal information provided, but I doubt you're seeing dryer lint. Dust fibers from clothing and toilet tissue accumulate on exhaust fan grilles. They need to be pulled down and cleaned at least annually.
Actually, the fan blades do, too. In some cases the moisture and dust conditions are so severe that the blades get completely coated and blocked over time, such that the fan moves virtually no air.
