Your crawl space is impacting your home comfort.
If your crawl space looks like this
your indoor air quality is suffering. You are also paying too much to heat and cool your home. A vented crawl space usually has insulation located in the joist spaces. This insulation gets pulled away from the heated surface by moisture in the crawl space opening up air gaps and reducing 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 has 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. This is a properly insulated and sealed crawl space.
