Nashoba Air and Boiler Works Duct Clean and SealOne of the most overlooked improvement to your home’s energy efficiency is proper duct sealing.  By taking the time to improve your energy efficiency early on in your home’s life, can save you enough money to pay the investment off. Savings is not the only benefit of duct sealing.  You will also experience improvement in your home’s comfort, safety, higher air quality, and with a more efficient home, you will reduce your carbon footprint.

Saving Money

Whether it’s the 90 degrees in July or 25 degrees in January, your home can stand to lose a significant amount of air throughout the year with leaky ducts. A properly sealed duct can ensure that you are getting the most from your duct system.  Leaks in your home’s ductwork can reduce heating and cooling system efficiency by about 30-40%. The cost of properly sealing your duct systems can eventually be paid off with the money you save from the energy savings.

Air Quality

The air you breathe is crucial to your family’s health.  Properly sealed ductwork can ensure that your family is not exposed to any unexpected bacteria. Chemicals, dust, pollen, and particles from your insulation can enter your duct if not properly sealed, and can cause allergy problem and be an issue for anyone suffering from asthma in your home. A properly sealed ventilation system will improve your home’s air quality and reduce the amount of pollen in your home during the spring.


Unfamiliar to most homeowners, gas appliances like clothes dryers, water heaters, and furnaces will release combustion gas, such as carbon monoxide, into your duct system. If your duct system is not properly sealed, these gasses can circulate through your home and be harmful to your health.

Uneven Air Distribution

If you ever feel that one room in your home is hotter than the rest of the home during the summer, it is probably because you have a leak in your duct system.  We have come across duct leaks as large as a golf ball and even airs ducts that are not even connected.  No wonder that back bedroom never got warm or cool?  

Reduced Carbon Footprint

More often than not the energy that we use to power our homes comes from the burning of fossil fuels at power plants.  This leads to increased smog and climate change around the world. With an efficient ventilation system, you will reduce the amount of energy used each year and the amount air pollution generated.

Homeowners have a lot to gain from a properly sealed duct system and with the investment nearly paying for itself, there are little reasons not to consider it for your home. If you have any question about duct sealing, please contact Nashoba Air & BoilerWorks today at 978-486-0600.
