Ohio Coroner-Crime Lab Improves Indoor Air Quality Using AerosealAndrew at Aeroseal
The Miami Valley Regional Coroner-Crime Lab in Dayton, Ohio Fixed Odor Issues by Sealing Its Ductwork Using Aeroseal
When decomposed bodies are found in Ohio’s Montgomery County, they get sent to the Miami Valley Regional Crime Lab for autopsy. For years, occupants of the three-story facility knew whenever a new body arrived because the strong smell of the rotting corpses would permeate the building. Despite spending hundreds of thousands of dollars over a period of years trying to solve the problem, nothing seemed to work. The facilities staff tried replacing the heating, ventilation, and air conditioning (HVAC) equipment, installing high-efficiency fans, adding an exhaust system incinerator, and insulating the walls. The odor issue was still there.
Finally, the third engineer entrusted with solving the dire IAQ problem saw an episode of “Ask This Old House” on the Public Broadcasting Service (PBS) featuring Aeroseal technology, a computer-controlled, aerosol-based duct sealing process that seals air leaks from the inside of the ductwork. He believed he might have finally found an answer to the problem.
- Building: Miami Valley Regional Crime Lab
- Location: Dayton, Ohio
- Aeroseal Contractor: Service-Tech Corporation
- Goal: Fix odor issues and improve ventilation in local government building
- Before Aeroseal: 988 CFM of leakage
- After Aeroseal: 43 CFM of leakage
- Results: Sealed the building’s air duct system to 96% reduction in leakage; Eliminated the migration of odors throughout the building via duct leakage
Once hired, the Aeroseal contractor/partner Service Tech Corporation took only two days to completely seal the supply and exhaust ductwork using Aeroseal. The final report generated by the computer-controlled sealing system showed a 98% reduction in leakage. More importantly, the facility director and the building’s occupants declared the problem 100% solved!
Bill Epperson, Associate Engineer, Montgomery County Government: “I knew we had leaks in the ventilation system that allowed the spread of odor throughout the entire building, but there was no way we could access and seal the ductwork without completely tearing down the entire structure. Over several years, we spent well over a hundred thousand dollars in new equipment and outside consultants trying to solve the problem, but nothing worked. Then we tried aerosealing, and the problem was solved. I wish all of our projects went this fast and smooth. The Aeroseal team was ‘in-and-out’ in just a couple of days. The fact is: any ductwork that has been installed a while ago has leakage issues. I’m looking at using Aeroseal to seal the air ducts throughout many of our facilities.”
Jeff Hatton, Energy Management, Montgomery County Government: “Sealing the ductwork using Aeroseal not only solved our critical ventilation issue, but it allowed us to lower fan speeds while increasing HVAC efficiency. There is no doubt that the duct sealing process had a significant impact on reducing energy usage and saving the county money.”
