We had a country house built several years ago. Included was a Venmar hepa3100 air exchange unit. We had it running initially but I found that when it was running it brought the stinky air from the basement( which isn’t finished) into the rest of the house, a two story cottage. When I mentioned this to the contractor, he said it was normal for the unit to draw air from outside, and circulate from the basement on up. There are two vents, one in the basement on the ceiling and one on the second floor ceiling. There are also Two air vent holes in the floor at either extremity of the home on the main floor. We haven’t used the unit nor for several years but it’s something that’s always irked me and I find that the air in the basement is often stagnant. I’ve always suspected that the unit was installed incorrectly….thoughts?
