A homeowner in Fredericksburg was struggling with a persistent, frustrating problem: a long term decline in their single-family home’s HVAC performance. Hidden, extensive duct leaks were robbing the system of efficiency, meaning conditioned air, both heating and cooling, was being lost before it reached the living spaces. This critical issue resulted in uncomfortable temperature swings, unnecessary wear on the HVAC unit, and escalating utility bills.
The customer needed a permanent repair that would restore comfort and efficiency without a costly system overhaul. They ultimately selected C.D. Shanahan’s due to a friend’s referral and our team’s responsive, detailed discussion about the duct leak problem and the effective solution.
To address the severe air loss, C.D. Shanahan’s implemented a highly specialized repair solution: Aeroseal technology. This process is a non-invasive, targeted method where a polymer sealant is injected into the duct system. The sealant finds and seals every crack and crevice from the inside, effectively creating a completely sealed air distribution path. Our team was able to complete this targeted repair and the entire process in just one day, ensuring minimal disruption to the family’s daily life.
The repair delivered an immediate and measurable return on investment. Before the service, the home was experiencing a significant 34% air loss due to duct leaks. After the Aeroseal application, that air loss was reduced to an outstanding 2%. This dramatic improvement meant that conditioned air was now staying in the home’s living spaces instead of being wasted in the attic, resulting in a documented saving of 400 cubic feet of air flow per minute.
The customer immediately noticed the difference in air quality and comfort, as affirmed by their testimonial:
“We saw an immediate improvement in the air flow in our home after you completed the seal work, and the following month we saw significant savings on our energy bill as well!”
By addressing the core problem of leaky ducts, C.D. Shanahan’s Heating & Cooling delivered a fast, measurable, and lasting improvement in home comfort and energy efficiency.
