Homeowners often do not consider improving conditions in the crawlspace as an important step in an energy efficient home especially when mold or crawlspace deteriation creates an odor in your home that can only be resolved through crawlspace maintenance and repair. The truth is crawlspace sealing or conditioning a crawl space is one of the most important steps in an energy efficient home. A conditioned crawlspace not only helps to eliminate humidity to control the possibility of mold growth but also helps your air conditioner perform more efficient by not having to overcome excessive crawlspace humidity.
One of the main functions of an air conditioner is to eliminate humidity in the air. Eliminating cold air in the crawlspace is vital to the performance of your heating system. Once again if cold air is not entering your crawlspace through your foundation vents your heating system will perform more efficient.
