A home with a dirt crawl space costs more to heat and cool. Besides all the reasons we already mentioned, there are other factors working against you. If your crawl space is vented, those vents make your floors cold upstairs. This is not only uncomfortable, but it means that it will cost more to heat your house.
Houses with dirt crawl spaces have damp air. Damp air uses more energy to heat and cool, and more energy costs more money. Damp air puts more of a latent (hidden) load on the HVAC system. Everyone knows they need to run their AC more on a humid day. But what about humidity from inside the building? Same thing. If you get rid of the humidity from your crawl space, you save money on heating and cooling costs.
You will save 15% to 25%. That's a lot of money! Over the years, it really adds up. Every month you are paying the price for living in a house with a dirt crawl space. Of course, there are variables, such as how many vents you have, whether you live in a one- or two-story home, whether you have ducts in the crawl space, how big your crawl space is, etc.
These penalties for living with the dirt crawl space problem, and the savings from fixing it, are real and proven.
