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

Published on: August 9, 2012

Areas sealed around ductwork openings have several benefits and your system operates efficiently while improving the quality of your home’s indoor air. Most of the air conditioning system’s ducts are behind walls; however, if open doors or older inefficient windows are not the reasons for warmer air, then have your ducts professionally inspected. Although you had recent air conditioner repair or service, it is a good idea to have every duct opening checked for leaks.

More Comfort

If you notice that the rooms in your home feel warmer than usual, or that it takes longer to cool down your home. You may not realize that leaky ducts could be the problem. Air conditioning systems work harder to cool down homes especially if ducts are leaking conditioned air. Drafty windows are not the only places where precious heated and cooled air escapes. As well as that, excessive moisture causes mold throughout the system and your home. Over the course of time, dust mixed with moisture destroys furnishings and fibers.

Increased Energy Efficiency

Properly sealed ductwork increases your system’s energy efficiency and saves on utility bills. When there are leaks, an air conditioning system operates 20 percent less efficiently. If the usual temperature setting leaves your home feeling warmer than usual, you should visually check ducts for gaps and areas where leaks occur.

Lower Utility Bills

Besides saving money and energy, another benefit of sealed ductwork is lower utility bills. Higher than usual monthly bills are often the first signs that you may have a problem with ducts that leak air. In addition to that, when your system is operating at peak efficiency without working harder than necessary, you save on air conditioner repairs. Over the lifespan of a system, you save on monthly utility bills and annual energy costs when you have leaky ductwork sealed.

Healthier Indoor Air Quality

Particulates, allergens, and other harmful bacteria enter through the ducts of your system and circulate throughout your home. It is yet another reason HVAC contractors recommend, sealing and cleaning duct systems. Although ducts are out of sight, many times homeowners do not consider them as part of the air conditioning system. Dust, moisture, and microorganisms enter through ducts and are some causes for unnecessary air conditioner repairs. As a result, these contaminants spread and aggravate those suffering from respiratory conditions such as asthma. The Environmental Protection Agency considers indoor pollution just as polluted as the air outside.

Higher Incidence of Backdrafting

Gas dryers, furnaces, and water heaters could pose a health hazard to your family. The ventilation systems release the accumulated combustible gases such as carbon monoxide safely outside. However, if duct openings have gaps or unsealed areas, the built up gases seep into your home and causes ‘backdrafting’ as a result. Any exposure to carbon monoxide could result in poisoning and future health issues. Whenever you have air conditioner repair or maintenance work performed, a technician will inspect ducts for leaks and gaps around the vents, registers, and other duct openings.
