💧 AC Humidity Correction — Georgetown TX

An oversized system cools to setpoint too quickly and shuts off before running long enough to dehumidify. Dehumidification requires sustained runtime — the coil needs to stay cold long enough to condense moisture from the air. Short-cycling oversized systems in Georgetown new construction are the most frequent source of "cold but sticky" complaints.

Air moving across the evaporator coil too quickly doesn't have enough contact time to lose moisture. Some HVAC systems in Georgetown are installed with fan speed set one notch too high — often done by installers to improve sensible cooling performance without considering latent load. Reducing fan speed by 10–15% can improve dehumidification significantly without replacing equipment.

Homes with ERV/HRV or fresh air dampers that are set too open continuously introduce Georgetown's humid outdoor air into the conditioned space. During July and August, Georgetown outdoor dewpoints routinely run 65–72°F — introducing that air requires significant latent cooling capacity the system may not have.

Homes near the San Gabriel River in Parkside and lakeside properties in Granger carry measurably higher ambient humidity than Georgetown's upland neighborhoods. Systems sized for inland Georgetown may be undersized for riparian humidity. A whole-home dehumidifier is often the cost-effective solution rather than equipment replacement.
