Return on InvestmentDiscover how Aeroseal Montreal could save you money!
This inside out approach makes it possible to seal all the leaks – even those hidden behind walls or other hard-to-access locations- that can’t be sealed with tape or mastic. As soon as the leaks are sealed, the savings begins.
“The Aeroseal process has proven to be 95% effective at sealing duct leaks. It is quickly replacing traditional tape and mastic, because it is the only guaranteed method of sealing ductwork and attaining the construction code requirements in both energy efficiency retrofits and new construction.”
Last year, a homeowner called who was looking to save energy and improve the indoor comfort of his 2,600 ft. home. After a quick inspection and testing, it was determined that 1/3 of the home’s heated and cooled air was being lost through leaks in the duct work. This was not only a waste of money, but the efficiency of the air conditioner and furnace were greatly reduced. The duct leakage was also responsible for rooms that never got warm enough in the winter or cool enough in the summer.
In less than four hours the Aeroseal equipment was set up and from one injection point in the furnace room, the home’s entire duct system was sealed. Post measurement tests found that Aeroseal had reduced overall duct leakage from 441 CFM (cubic feet per minute) to 16 CFM – a reduction of more than 96%.
Using records recorded by the home’s programmable thermostat, the homeowner was able to determine the annual savings obtained by having his home Aerosealed. He set the thermostat to 21 degrees and compared the operation of his furnace before and after the process. By comparing two days that had similar weather conditions, he found that the furnace turned on 11 times before the system was Aerosealed and only 7 times after. The furnace run times during the similar 24-hour period also dropped by about four hours.
With this data comparison, the homeowner determined that the Aeroseal process reduced annual heating and cooling expenses by about $600 – a two-year return on investment. “This is real tangible evidence that the process works,” said the homeowner. “My wife – an eternal skeptic – has noted that the house has felt warmer and more consistent in temperature with more heat coming through the vents. I am a believer in this technology.”
