Duct Repair & Inspections Save Energy

If you are like most home and business owners, as long as your cooling and heating system is keeping you comfortable, you usually don't give it much thought. However, what you don't see could be costing you money. Most duct systems are installed in attics or in the crawl space where they are rarely seen or inspected. They may have been poorly sealed when installed, fittings may have come loose, and duct runs may have become disconnected. It's not uncommon to see ducts torn apart or disconnected by rodents, or completely crushed after the "cable-guy" crawled through. All of this leads to a lot of lost air - air that you pay to heat or cool.

In fact as much as 35 percent of a home or businesses heating/cooling airflow could be leaking through the ducts, causing a loss of comfort and cooling capacity. On average, almost 15 percent of cooling energy is wasted due to duct leakage.

While it's almost impossible to completely seal a duct system. It is possible to design and install ducts and achieve result of 3 to 8 percent leakage. If your home has ducts located in an attic, crawlspace, or the garage there is a good chance it has some duct leakage. So be sure to have your ducts inspected once a year. The savings you'll experience could easily add up to a few hundred dollars per year.

Duct Damage and Leaks

Duct will typically leak at connection points. There is a common test that can be performed called a HERS test that can determine the amount of air leakage. These test typically run about $300 to $500 and take about 2 hours to complete.

A little self diagnostic can also help find leaks. The first thing to look for is disconnected ducts, such as the one shown below. If you ducts are wrapped in fiberglass, a good indication that you have a leak is any black or gray markings in the insulation. The fiberglass acts like a filter as hot or cold air is pulled into the duct by the air handler fan.

Another good place to inspect is around register cans. We typically find about 5 to 10% air leakage here. Apply mastic or use butyl tape to seal these areas.
