Why South Park Homes Face Unique AC Drain Challenges

South Park’s mix of historic and mid century homes creates specific vulnerabilities. Many properties have attic HVAC units installed decades ago when building codes were less strict about secondary drain pans and safety switches.

South Park’s humid climate means AC units run almost constantly from May through September. That heavy use accelerates algae growth inside drain lines. A line that stays clear all winter can clog completely by July.
