Air Duct Sealing & Duct Testing


Carrier - Duct & Dryer Vent Sealing

What is Duct Testing?

Duct Testing is a new requirement in the California Energy Code. Whenever a furnace needs to be replaced, the duct system must be checked for air leaks, and then sealed to achieve a certain allowable level of leakage. This improves system efficiency and saves energy for everyone. Heating and cooling is one of the biggest areas of energy use in our state. The results are reported to the State of California. The paperwork process is similar to a smog test.

A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow. The combination of pressure and fan flow measurements are used to determine the ductwork airtightness. The airtightness of ductwork is useful knowledge when trying to increase energy conservation.

Duct Sealing

In homes with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is 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.

A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer. Contact us for a quote to seal the ducts in your home and improve the performance of your heating and cooling systems.
