Frequently Asked Questions

In houses with central heating and cooling systems, ducts distribute conditioned air throughout the house. In a typical house, about 20-30 percent of the air that moves through the duct system can be lost due to leaks, holes and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set. Leaks can happen in the supply line and the return line, so you could be pulling hot air from your attic into your home, or you could be spending money to heat and cool your attic. Either way, it's a waste of money.
Some signs of air duct leaks include:
- Unusually high summer and winter utility bills.
- Rooms that are difficult to heat or cool.
- Stuffy rooms that never seem comfortable.
Most homes do have some duct leakage, but it is important to understand the extent of the leaks. If you feel that this may be a problem in your home, contact one of our Energy Advisors. These energy experts can answer any questions you have about how to make your home more energy efficient and help you take care of any identified leaks. They may recommend that you have a duct test, which will help pinpoint any duct leakage.
During the duct test a Duke Energy contractor will:
- Use a fan system to pressurize and depressurize the house, measuring how air tight the house is.
- Create a diagram of your entire duct system, clearly identifying leaks that should be sealed and any other areas that need repair.
- Give you a complete estimate of any repair costs-including the Duke Energy incentive.
