Adding to the services they provide, Atlas now includes Duct Sealing

With ductwork being a critical part of any forced air conditioning system, the amount of air being properly delivered greatly affects the comfort and efficiency of a home. HVAC units with leaky ductwork will  run for longer cycles to heat or cool the home which in turn means more wear and tear on the components of the system in addition to higher utility costs. Being able to achieve a comfortable temperature while saving on heating and cooling is what an efficient duct system is designed to do. So why let leakage continue to cost extra money?

Most duct leakage occurs at the connection points between sections of ductwork. Before the 1990’s, these joints were typically never sealed and most older duct systems can leak between 20% and 40% of all their air before reaching the furtherst rooms from the furnace. For the past 20 years, the main method for sealing these joints was manually with duct/metal tape or mastic. These methods can work well when done diligently throughout the initial construction process, but unfortunately, many duct systems were only sealed in specific locations like the utility room, or on the supply side and still leak over 20% of their air. 

In existing houses, manual sealing of the remaining duct leaks is very difficult or prohibitively expensive because the ductwork is behind drywall, buried in an attic or hung up against the underside of a floor. Now there is a new method to seal ductwork, from the inside, with Aeroseal.

The entire process can be seen here, but a quick overview is below:

  • Supply and return duct registers and covers are removed and temporarily blocked
  • Access holes are made in the plenums at the HVAC unit
  • The HVAC Equipment is seperated from the ductwork with blocking to prevent sealant from getting into the heat exchangers
  • The AEROSEAL equipment is connected to the duct system with a flexible tube
  • A duct leakage test is performed to determine how much air is leaking out of the system
  • Sealant is injected into the duct system, with all of the duct registers blocked, the sealant can only get out of the gaps and cracks in the duct system. As the sealant is forced through these small holes it clings to the perimeter and slowly closes the hole.
  • The duct leakage is monitored throughout the sealing process to ensure that all duct leaks are sealed – Typically 80% of All Duct Leakage are eliminated
  • Once the sealing is complete, the system is tested once again for a final duct leakage measurement
  • The blocking is removed and the covers are reinstalled
  • A Report is generated for the homeowner that shows how leaky the ducts were, how much duct leakage was removed, and how much more efficienctly the unit will now operate

Many homeowners who have had the service rave about

  1. How much more air comes out of their registers
  2. How much more even the temperatures are around the house
  3. How much less dust there is throughout the house
