What We Work Performed

The air handler coil was clogged with dust and debris buildup, causing restricted airflow and putting extra strain on the system components. This buildup was leading to inconsistent cooling and higher energy consumption.

Our Comprehensive Maintenance Plan: What We Check

Your membership includes two comprehensive visits per year—one for the cooling season and one for the heating season—to keep your systems in top shape.

Our Repair Process

To bring the unit back to life, we performed a full-service repair:
  • First, we opened the air handler and inspected the internal coil for dirt buildup
  • Used specialized HVAC coil-cleaning tools to remove dust, debris, and blockage
  • Cleaned the drain area and ensured proper refrigerant flow
  • Checked all electrical components and wiring connections
  • Reassembled the unit and ran a full operational test
  • Verified airflow output and system temperature performance

The Result

Within minutes of restarting the system, the difference was dramatic:
  • Airflow increased significantly after deep coil cleaning
  • Cooling efficiency improved and the home reached desired temperatures faster
  • System noise reduced and strain on internal components decreased
  • Lower energy usage due to improved efficiency
  • Air handler running smoothly with optimal performance restored

Our Outcome

After a thorough coil cleaning and internal service, the air handler’s airflow improved significantly. The system’s cooling performance was restored to normal levels, and the homeowner noticed immediate improvement in indoor comfort.
