Real buildings, real measurements: what the problem was, what changed, and what the numbers showed afterward.
Each case study below starts with a specific problem, explains the fix, and reports the before-and-after readings. They are written for homeowners and building managers who want to see how a solution performed before deciding on one.
A 12-year-old 1.5-ton single-stage system in a 1,039 sq ft Zilkr on the Park condo let indoor humidity reach 65-72% even at 68°F.
After an upgrade to a 2-ton variable-capacity inverter heat pump, the condo held 41-46% RH at a 74°F setpoint.
A U.S. Army ERDC study tested Pure Maintenance’s two-step dry-fog process in two vacant Fort Campbell buildings.
It found large, immediate drops in airborne and surface mold spore counts, with indoor levels about 95-99% below baseline after six months.
Buyers of a South Austin home asked us to inspect three nearly new heat pump systems before closing. We found restrictive ducts, high static pressure, suspected mold and a humid attic.
After closing, a full mechanical remodel rebuilt the ductwork and zoning, added a mini-split system and a whole-home dehumidifier.
New case studies are added to the Resource Center as projects wrap up. You can also browse our Homeowner Guides for plain-English help with your own system.
