Home's Negative Pressure Caused Health Issue ... Here's How it Was Solved

Home’s Negative Pressure Caused Health Issue
Dayton, Ohio Homeowner Tammy Lua has lived in her home for 18 years with her husband Mark. During that time, she has suffered from severe sinus pressure. She knew her home was making the problem worse.
Multiple Attempts to Solve Problem She oversaw multiple renovation projects that she helped would remedy the situation – insulating the attic, replacing the roof, and insulating the home’s soffit vents. But her sinus issue persisted. And her home was uncomfortable, with uneven temperatures throughout.
Lua suspected her home’s HVAC system was part of the issue. She knew it wasn’t cooling the home evenly and it was making her home dustier than normal, which was in turn contributing to her sinus issues.
