I bought my first home about 1.5 yrs ago. It was constructed about 1995. It has an Armstrong Ultra SX 80 furnace.
I recently layed laminate flooring in a bedroom, when I took up the baseboards I noticed that the drywall did not sit on the floor but sits on nails about an inch off the floor. I had never seen this before so I started asking some questions; I was told this was for "ventillation" and someone else said it might be how cold air enters the house.
I have also noticed that things will mold much more quickly then any home I have lived in. This indicates to me a problem with air circulation.
Would someone explain how I can tell if I have proper circulation in this house?
Thanks for any advice.
