Frequently Asked Questions

High humidity forces HVAC systems to work harder to remove moisture and maintain comfort, which can increase wear and energy use. Systems must be properly sized and maintained to handle the Midlands' year-round humidity levels. At White Knoll Heating and Cooling, we design installations and repairs with South Carolina's climate demands in mind.

Many homeowners select systems based on price alone without considering proper sizing for their building's square footage and usage patterns. An undersized or oversized unit will struggle with efficiency and comfort. At White Knoll Heating and Cooling, we provide honest recommendations based on over 30 years of sizing experience.

Leaks and aging materials are common in Midlands homes and directly reduce system efficiency. At White Knoll Heating and Cooling, we evaluate duct conditions and explain all repair or replacement options clearly.

UV light systems reduce airborne contaminants by targeting mold, bacteria, and allergens as air passes through the HVAC system. This supports cleaner airflow and improved indoor air quality, especially beneficial in humid climates. At White Knoll Heating and Cooling, we assess each home to determine if UV light installation is a suitable air quality solution.

Replacement is typically recommended when repair costs exceed half the value of a new system, or if the unit is over 15 years old with declining efficiency.
