FIGURE 3A Supply Air to Crawlspace. When you supply air to the crawlspace from an air conditioner or furnace there needs to be a way for air to come back to the house,
besides poor workmanship. A transfer grille is recommended. FIGURE 3B Return Air from Crawlspace. If you pull air out of the crawlspace with a return duct, there needs to be
a way for air to get from the house to the crawlspace. A transfer grille is recommended. FIGURE 3C Supply and Return Air to and from Crawlspace. If you supply and return air
to the crawlspace from an air conditioner or furnace you need a way to balance the airflows to avoid pressure differences. A transfer grille is recommended. FIGURE 3D Supply

Fan to Crawlspace. You do not need a furnace or air conditioner with ducts to condition crawlspaces. You can do it with a supply fan, but you still need a pathway back to the
house. A transfer grille is recommended. FIGURE 3E Exhaust Fan from Crawlspace. You can use an exhaust fan to pull air out of the crawlspace and exhaust this air to the
exterior pulling makeup air for the crawlspace from the house. FIGURE 3F Crawlspace Dehumidifier. If conditioning crawlspaces with air from the house is not desirable, install a
dehumidifier. The dehumidifier handles the moisture control.

Do you need a furnace or air conditioner with ducts to
condition crawlspaces? Nope. You can do it with a supply
fan (Figure 3d), but you still need a pathway back to the
house. Yup, transfer grilles again.
Let's look at Figure 3e. Can you use an exhaust fan to
pull air out of the crawlspace and exhaust this air to the
exterior pulling air from the house? Yes. You can vent
the house through the crawlspace-exhaust only ventilation with makeup air supplied to the crawlspace from the
house (Figure 5).§
What if I do not want to do this conditioning with
air from the house? OK, check out Figure 3f. Install a

FIGURE 4 Transfer Grille. Best location is in an interior wall thereby avoiding
floor grilles that can be blocked with furniture and that can lead stuff falling into
crawlspaces.

§This is a powerful approach when houses with moldy crawlspaces are retrofitted. Sometimes, there are limited funds available
to completely decontaminate a moldy crawlspace. Continuously
depressurizing the crawlspace relative to the house uncouples
the crawlspace from the house. Of course, the original moisture
problem causing the crawlspace mold needs to be addressed. An
exhaust fan does not solve ground water problems. But installing a
ground cover, sealing crawlspace vents and running an exhaust fan
to the exterior does address most other issues.
