A Case Study for the Aeroseal Process

A Case Study for the Aeroseal Process…while I have many similar case stories to tell, I thought you would like to hear about a case study for the Aeroseal process, before and after the process. You too can achieve these types of results by using the Aeroseal process.

A Case Study for the Aeroseal Process


 Fast And Simple Process Proves To Be Best Financial Investment For HomeownersA Case Study for the Aeroseal Process

 A simple duct test showed that leaks throughout the ductwork were responsible for a leakage rate of 441 CFM. That meant that nearly 1/3 or the air being heated by the furnace or cooled by the air conditioner was being lost through holes in the duct system. This was not only an enormous waste of energy but most assuredly was also responsible for the uneven temperatures throughout the home.

Using, Aeroseal, an innovative approach to duct sealing,  the ECS team corrected  the problem in a single afternoon. After we completed the Aeroseal process, the post-seal testing showed that leakage reduced to 16 CFM or just 1% of total output – a 97% reduction in leakage. The homeowners observed that while their house was warmer than ever before, their furnace was turning on far less often and for much shorter periods of time.

In Brief Building: 2,600 ft2 home; Beacon Falls, CT.

  • Goal: Reduce energy usage – improve evenness of home’s room to room temperatures.
  • Before Aeroseal: 441 CFM of leakage
  • After Aeroseal: 16 CFM of leakage
  • Results: Before aerosealing the furnace cycled 11 times in a 24 hour period. After Aeroseal, the furnace cycled only 7 times and reduced its overall run time by 4 hours over a similar (weather conditions) 24-hour period.
  • Estimated $600 annual savings.

Dennis K heard that effectively sealing the ductwork of his home could reduce his home energy bill. He had no idea that it would turn out to be the best financial investment he made in years. Dennis called the Aeroseal experts at ECS Connecticut, hoping to reduce the amount of energy used to heat and cool his 2,600 ft home. He was also hoping that duct sealing would improve the comfort of the house, getting adequate heat and air conditioned air to all the rooms, both upstairs and down.

The home energy pros at ECS tested the home’s ductwork for leaks. The duct system was divided into two zones: one that serviced the first floor and another dedicated to the second floor. The two systems together were designed to handle a total output of 1,400 cubic feet per minute (CFM).

“Given the data collected from my programmable thermostats, you can visually see that the furnace is NOT cycling on and off as frequently anymore. The change is quite dramatic. My wife – an eternal skeptic – has noted that the house feels warmer and more consistent in temperature. More heat is coming through the vents. This is real tangible evidence that the process works.”

Dennis K, homeowner

“We find that, in most every home we’ve tested, leakage rates easily run 20% to 30% or more. Since most of the ductwork is hidden behind walls or other impossible to reach places, the inside – out approach to duct sealing is really the only viable means of effectively sealing those leaks.”
