Dirty AC coils in Corsicana can decrease efficiency and increase energy costs. Regular cleaning and maintenance can prevent this issue. Check for dirt buildup and clean if necessary.

As North Texas transitions into late fall, residents in Corsicana and nearby Ennis face unique HVAC challenges due to seasonal cold fronts and local weather patterns. A common issue that can arise is dirty AC coils, which significantly affect your system's efficiency and lead to higher energy bills.

Why Are Dirty Coils a Problem?

Dirty condenser coils can lead to decreased airflow, reduced cooling capacity, and increased energy consumption. In Corsicana, where lakefront properties at Richland Chambers Lake often experience higher humidity levels, coils can quickly become covered in debris.

3 DIY Checks for Your AC Coils

  • Visual Inspection: Check for visible dirt and debris. A clean coil should have visible fins without layers of dirt.
  • Airflow Test: Feel the airflow coming from your unit. If it's weak, it might be time for a cleaning.
  • Temperature Check: Use a thermometer to measure the air temperature difference between the intake and outflow. A difference greater than 20ยฐF indicates potential issues.
