Is it normal to have a draft of air coming from your basement to the

If you realy want to know and not guess get an energy audit and a
blower door test, even a blower door test itself will give a printout
of how many air exchanges per hour your house has and should have. The
tech then pinpoints all the leaks with a smoke stick. Old houses are
leakers, the test might pay for itself in a few months, mine did. It
might cost 300, a full audit would be a few hundred more but will
eliminate guesswork on how to save on utilities.
