Ducts in your home are very important if you have any heating or cooling system. The ducts will both deliver and remove air in the rooms of your house to moderate the temperature and make it comfortable.
Make your home more comfortable for less money
If your air ducts have any leaks in them, you can be losing up to 20% of the air flowing through them. This is a problem because your HVAC system has already heated up or cooled down the air that is meant to regulate the temperature in your home. The cost goes up when you lose 20% of that air through cracks into the crawl space or attic of your home. More air has to be pushed through the ducts in order to make up for the lost air. The leaks can also suck in outside air, which will ruin the effectiveness of the HVAC system since it will cool down hot air and heat up cool air. Sealing these ducts obviously have a huge benefit to the cost as well as comfort of your home. There are many different materials that ducts can be sealed with, and an energy *specialist, technician* will be able to find the right fit for your ducts.
Along with Insulation
Insulating ducts is also something that you should look into, especially if the duct runs through a particularly cold or hot area of the house, such as attics or crawlspaces. The ducts will become the temperature of the surrounding air, and it will make the air inside the ducts work much less effectively.
