5 Benefits of Duct Sealing in Your Home
Chances are you understand the benefits of sealing leaks around your doors and windows, but do you know that duct sealing also has significant benefits? Aeroseal is a simple, six-step process that can increase your home’s comfort, improve indoor air quality and save you money on energy costs.
A typical home loses 20-40% of its heating and cooling energy to leaks, holes and gaps in the ductwork. That’s the equivalent of leaving a window open every day of the year. A properly designed, installed and sealed duct system, however, can lower energy costs while boosting comfort levels. Why throw money away? Here are 5 real benefits of sealing the ducts in your home:
Homes with duct leaks often experience hot or cold spots, or inconsistent temperatures from one level to another. This is because much of the heated or cooled air never makes it into the living areas, but instead is lost to the attic, basement or crawl spaces.
2. Indoor Air Quality
Holes and gaps in the ductwork can attract dust, debris and allergens from the internal spaces of your home and then deposit them in the living areas. This may include fumes from household chemicals, insulation particles and other pollutants, which can be especially aggravating to those with allergies, asthma or other respiratory illnesses. When ducts are properly sealed, the risk of contaminants entering and circulating throughout your home through your HVAC system is dramatically reduced.
Gas appliances such as water heaters, clothes dryers and furnaces are designed to release combustion gases through their ventilation systems. Leaky ductwork in your heating and cooling system, however, may draw those harmful gases back into the living spaces of your home, rather than directing them outside. This is know as “backdrafting” and can be extremely dangerous, even deadly. Sealing duct leaks can minimize this risk.
4. Save Money
Leaky ducts can reduce the efficiency of your heating and cooling system by as much as 20-40% percent. That inefficiency increases your energy costs in several ways:
- You are paying to heat and cool air that never reaches the living spaces of your home.
- Your HVAC system has to run longer and work harder in an effort to maintain the proper temperature. That extra wear and tear leads to more costs down the road in the form of more breakdowns and repairs, and a shorter life for your system.
- Sealing ducts saves money by increasing efficiency, and can often pay for itself with lower energy bills.
- When you do need to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly system.
5. Protect the Environment
Saving energy in your home not only benefits you, it’s good for the planet. The energy from power plants often comes from burning fossil fuels, which contributes to smog, acid rain and climate change. Less energy use means less air pollution.
