Just like the other aspects of heating, ventilating and air conditioning (HVAC) systems that the duct work remains virtually undetectable to many people. Out of sight out of mind, right? In other words, unless there's a problem with it. HVAC businesses understand that a correctly installed and maintained HVAC duct system is critical to safety and energy efficiency.
A leaky HVAC duct system could lead to a condition known as back draft. This is when combustion gases in the furnace are vented into the living space instead of outdoors. Leaky HVAC ducts can promote poor indoor air quality by allowing insulation particles pollutants from outdoors to enter the ducting and circulate across the home.

From an energy efficiency standpoint, leaky vents are a problem because heated or chilled air can leak out instead of being directed where it was designed to proceed. Energy (DOE), has ascertained in a typical home, near to 20% of energy used in heating and cooling systems is wasted because of HVAC duct flows.
You'll find a number of indicators which can provide clues to answer this particular question. If you have ducts in the attic or other space vulnerable to outdoor atmosphere, these need to be sealed tightly, but most likely they are not. For those who have tangled elastic ducts on your system, it may lead to pressure to develop which forces air out through tiny openings.
For those who have rooms which can be difficult to cool or warm, or rooms that feel stuffy, this can indicate the problem. And, when you have high bills in the summer and cold temperatures you might have leaky ducts. If you have any mixture of the above mentioned indicators it will be worth your time and attempt to own your HVAC duct system inspected for leaks.
