then your indoor air quality is suffering. You are also paying too much to heat and cool your home. Vented crawl spaces usually have insulation located in the joist spaces. This insulation gets pulled away from the heated surface by moisture in the space, which opens up air gaps and reduces any insulation value at all. The space usually has high humidity levels promoting mold growth. The heating and cooling vents running in that space usually have minimal insulation allowing for condensation to occur in the ductwork, again impacting indoor air quality and efficiency of the HVAC system.
Instead of a vented crawl space in our mixed humid climate, you should have a conditioned crawl space – like this one. Here is an example of an excellently sealed space.
