Most people assume that furnace filters are enough to collect the average amount of dust being circulated inside their home, but a leaky return will cause you to replace filters at a faster rate and if left in too long can put strain on your system. An unsealed air return duct system not only sucks in dirt, dust, allergens, smelly odors, and other pollutants from attics, crawlspaces, and interior walls, but it also brings in humidity from those very same spaces. The introduction of humidity into the ductwork causes comfort issues, and can also lead to mold growth. Sealing your return ducts eliminates the threat of moisture and mold as well as block out all those pollutants from being introduced into your home and being recycled over and over again every day.

Marshall Cleaning Service utilizes Aeroseal technology in order to keep your air ducts sealed tight to reduce the amount of dust in your home, improve the performance of your air duct unit, make your home more comfortable for you and and your family, and save you money by reducing your energy bill cost.

How Do We Know That Ducts Leak?

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. But in typical houses, about 25-40% 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.

Leaky Ducts Lead To Decreased System Performance

Sealing your ducts is the best way to achieve maximum efficiency from your equipment. Sealing and insulating your ducts increases system efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you’re planning to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.

"Since we had Aeroseal done at our home, our comfort level has improved exponentially! The dust in our home has also decreased and our utility bills have dropped! When we buy a new home, we will make sure to have Aeroseal done there too!"

- Linda J.

"The duct sealing application has made a huge difference in the quality of our 1959 one floor home. The past week of frigid weather was a good test. The new thermostat has remained at 72 degrees during the low temperatures below zero. The whole house feels much more consistently warm in each room."

- Tom G.

"Before sealing our ducts. there was a temperature differential of 15 degrees between the basement and the second floor. We had to run a single room AC unit in our master bedroom to get it cool at night. But now, the biggest temperature difference has been within 3 degrees! No more room AC unit for us! We are big fans of the Aeroseal process and we have told all of our friends!"

- Andrew & Erica M.
