Can High Electricity Bills Happen With a Basement? 

Crawl spaces are more common than basements, so you or someone you know may have one. Moisture and humidity can also affect the basement. Moisture can enter your basement through leaking pipes or a hole in the basement walls, causing your home’s humidity level to rise. Warm air rises, just as it would in a crawl space, and fills the rest of your home. As the warm air flows, your HVAC system will have to work more to keep your home comfortable.
