The SelectCycler System— a cost-effective, whole-house mechanical ventilation solution that complies with ASHRAE 62.2 — combines parts of central fan integrated and exhaust fan ventilation to provide an energy-efficient solution for supply or balanced ventilation. 

The John Wayne Birthplace is the only museum dedicated to John Wayne and contains more than $2 million worth of artifacts. So far, the HVAC design has proven more than capable in terms of occupant comfort, sustainable operation, and protection of artifacts.

Since Halloween is right around the corner, I thought it would be a perfect time to take a look at some of the ghosts in duct systems that are often tracked down by progressive HVAC companies.
