Ductwork - High Temps in Attics and Crawl Spaces Work Against Duct Taped Ductwork!

We never fail to find Duct Tape on Duct Work. For some reason it works on everything else just not duct work. High Crawlspace Humidity and Extreme Temperatures in the Attic just are not good for Duct Tape. Have your Duct Work Professionally sealed by Dr. Energy Saver. Don't be the typical home that looses 30% of your air before it ever makes it to the house. If the air is escaping on the Supply Duct, what's happening on the Return Duct? Ever wonder why so many people have Allergy Problems?
