A blower door test is worth it you will get a person experianced on
fining the leaks to show you, a printout of air exchanges per hour,
Ideas on cures, and what you need in air exchanges to be efficient,
usualy 2-350$ Or get a big fan and seal it in a door or window and test
yourself, but you wont know how your house rates.


Or is you have a whole house exhaust fan, just cut it on to the low speed
with the windows and doors closed.
