Our Comprehensive 3-Step Repair Process:

1. Advanced System Diagnostics

We start with a thorough inspection of your entire HVAC system, using precision instruments to test and measure performance indicators:

• Electrical Check: Inspecting and tightening all connections, testing voltage, amperage, and safety devices (capacitors, contactors).

• Refrigerant Monitoring: Checking line pressures and temperature differential ($\Delta T$) to confirm correct refrigerant charge and identify potential leaks.

• Component Testing: Testing the thermostat, compressor, fan motors, and blower wheel function.

2. Professional Repair & Component Replacement

Once the issue is accurately identified, we carry out the necessary, long-term repair, which may include:

• Leak Repair & Recharge: Finding and permanently sealing refrigerant leaks before recharging the system to the manufacturer’s exact specifications.

• Coil Cleaning: Cleaning dirty evaporator and condenser coils to restore maximum heat exchange and efficiency.

• Drainage Correction: Clearing and flushing clogged condensate drain lines to prevent water damage and potential mold growth.

• Faulty Part Replacement: Installing high-quality, manufacturer-approved replacement parts for motors, belts, circuit boards, and other critical components.
