Duct Sealing û 5 Benefits You Can’t Afford to Ignore

Published on: August 16, 2012

If you have a conventional central air conditioner unit, you also have a system of ductwork installed in your home. The duct system is the network of tubing that connects the HVAC unit to the rest of the rooms in the house, delivering heated and cooled air to each room. The conditioned air is passed through the duct system and then blown out of vents in each room. The effectiveness of the ductwork in delivering heated and cooled air throughout the home is a function of how well the ducts are sealed.

1.) Duct sealing increases the cooling and heating efficiency of the HVAC system.

If the duct network has leaks, bends or cracks, conditioned air is constantly seeping out of the system. This means that the rooms in the home are not receiving the cooled and heated air. The thermostat indicates the temperature of the room where it is located, and if air is leaking from the ductwork, the room where the thermostat is located is not properly receiving the conditioned air.

Because the conditioned air is not properly circulating, the HVAC system must work harder to heat or cool the home. As conditioned air is lost through leaks and gaps in the ductwork, the system must work harder to maintain the temperature set by the thermostat. When ducts are properly sealed, conditioned air reaches all rooms of the home, including the room where the thermometer is located. The air is efficiently heated or cooled, passed throughout the home and the thermostat properly registers the temperature. As a result, the HVAC runs less to provide conditioned air to the home.

2.) Duct sealing increases the energy efficiency of the HVAC system.

Because the HVAC system runs less to heat and cool the home, sealing the duct system also improves the energy efficiency of the home. Not only will conditioned air reach each room, improving the heating and cooling efficiency of the home, but as the system must work less hard, the system uses less energy. Duct sealing makes your HVAC system more energy efficient, which ultimately saves money on your energy costs for the home.

3.) Duct sealing will increase the life of your HVAC system.

Because the HVAC system runs less and provides conditioned air throughout the home more efficiently, there is less wear on the system. Duct sealing will extend the life of your HVAC unit, as well.

4.) Duct sealing will improve your home’s indoor air quality.

When ducts are not properly sealed, dust and contaminants will leak from the ductwork and into the air within the home. When pollutants are leaked into the air, these particles are inhaled by you and your family, compromising the air inside your home. Ducts that leak contaminants into the air greatly contribute to indoor air pollution.

5.) Duct sealing will make your home safer.

The duct system not only delivers conditioned air throughout the home, the system also carries harmful gases out of the home. One such gas, carbon monoxide CO2, can cause health problems and in extreme cases, even death. Sealing the ductwork in the home will ensure that CO2 is not leaking into the home from the HVAC system.

Sealing the duct system in the home provides many benefits, from saving money to ensuring the health of your family. If you have a conventional HVAC system, have your duct system inspected by a certified heating and air conditioning maintenance professional. A certified heating and air conditioning maintenance professional will examine the duct system for gaps, spaces and leaks in the network of tubing. The technician will check to ensure that the tubing is properly sealed at all points where the tubing intersects or meets a vent.

Duct sealing is an inexpensive way to improve the energy efficiency and extend the life of your HVAC system. Contact a certified heating and air conditioning maintenance company to have your ductwork examined and sealed, if necessary.

Other Duct-Related Factors

The duct system may become contaminated with debris, dust, contaminants and even mold. Many air conditioning maintenance professionals recommend that the duct system in homes be periodically cleaned. The U.S. Environmental Protection Agency (EPA) recommends that you hire only air conditioning maintenance companies that are certified in duct cleaning when to clean your duct system. In addition to cleaning the duct system, the air conditioning maintenance system will check for leaks and other problems that may affect the indoor air quality. For example, if moisture has leaked into the duct system, mold may have accumulated in the tubes or around the vents.

The duct system of the home is an important component of the HVAC system. When the duct system is properly sealed and maintained, the HVAC system will operate more efficiently and save you money on your utility bills.
