Providing Even Temperatures Throughout the House

Aeroseal Provides Dramatic Improvement in Indoor Comfort for Cincinnati-Area Homeowner

Breakthrough Duct Sealing Technology Reduces Duct Leakage By 90% AFTER Professional Manual Sealing Was First Attempted

Tim was frustrated with his HVAC system. No matter how high he turned up his air conditioner during hot summer days, the upstairs rooms in his Cincinnati, Ohio-area home remained about 10 degrees hotter than those downstairs. To solve the problem, he first tried replacing his old air conditioner with a new high-efficiency unit “guaranteed to solve uneven temperatures problems.”

When that didn’t work, he called in his HVAC specialist who showed him that the problem was due to excessive duct leakage. The specialist recommended using Aeroseal to seal the leaks. But Tim, a home repair contractor by trade, opted to spend several days manually sealing the ductwork himself. When all that hard work still didn’t solve the problem, he finally decided to try Aeroseal… and he was glad he did. Leakage was reduced by more than 90%. More importantly, the upstairs of his home is now as comfortable as the rest of the house.

Results

After sealing the ductwork, leakage measured only 22 CFM (supply) and 20 CFM (return). As a result, cooled air now reaches all intended destinations throughout the house, leaving less than 1 degree difference in temperature from room to room. The need to dust was also reduced from one time per week to one time every three weeks. As an added bonus, the homeowner saw his energy bill go down about $46 a month.
