Our Professional Air Handler Service and Diagnostic Process

Maintaining the air handler requires specialized knowledge to ensure all mechanical and electrical components are functioning in harmony. Our systematic service process is designed to diagnose issues accurately and restore your unit to optimal performance.

Comprehensive Component Inspection

Our service begins with a detailed inspection of the air handler’s key components, including the blower motor, fan belt (if applicable), evaporator coil, and internal electrical connections. We check for signs of wear, corrosion, or dirt buildup that can impede performance and efficiency.

Airflow and Blower Motor Diagnostics

We perform advanced diagnostics on the blower motor to measure its speed, voltage, and amperage draw. Proper blower function is essential for moving the correct volume of air through your home. We also assess the overall airflow to identify any restrictions caused by dirty coils or issues within the ductwork.

Coil and Drain Line Cleaning

The evaporator coil within the air handler is prone to accumulating dirt and biological growth, which severely restricts heat transfer and can contaminate your indoor air. We perform a professional cleaning of the coil and ensure the condensate drain line is clear and functioning correctly to prevent water damage and mold growth.

Final Performance Verification and Calibration

After any necessary repairs or maintenance, we verify the air handler’s performance by checking the temperature differential and overall system operation. We calibrate the unit to ensure it integrates seamlessly with your outdoor unit, maximizing the efficiency of your entire HVAC system.

Your Satisfaction is Our Benchmark of Success
