Repair Services Offered

• Refrigerant Leak Detection and Sealing: Advanced electronic leak detectors and nitrogen pressure tests locate leaks. We seal and repair lines, replace gaskets or couplings, and recharge the system to manufacturer-specified levels.
• Fan Motor and Blower Wheel Replacement: Brushless fan motors and precision-balanced blower wheels restore quiet, powerful airflow. Bearings, belts, or shafts are swapped out as needed to eliminate squealing or grinding noises.
• Electrical Component Swap: Failed capacitors, relays, contactors, or control boards are replaced with OEM-grade parts for reliable switching and voltage regulation. We secure connections, tighten terminals, and ensure proper grounding.
• Sensor Calibration and Replacement: Thermistor and humidity sensors are calibrated or replaced to maintain accurate temperature control and prevent short-cycling.
• Coil Cleaning and Condensate Line Clearing: Professional coil cleaning dissolves built-up dust, mold, and debris. Condensate lines are flushed and treated with anti-microbial agents to restore proper drainage and prevent blockages.
• Emergency Electrical Repairs: When wiring hazards or component failures pose safety risks, technicians address faulty breakers, short-circuits, or scorch damage to restore safe operation. All work adheres to local electrical codes.

Basic Troubleshooting Tips for Homeowners

• Check Power and Remote Settings: Ensure the outdoor unit’s breaker is on. Verify remote control batteries and mode settings (cool, heat, dry, fan only).
• Clean or Replace Filters: Rinse washable filters every 2–4 weeks or swap disposable filters to maintain airflow and indoor air quality.
• Inspect Indoor and Outdoor Coils: Look for visible ice or frost on indoor coils; allow defrost cycles to complete. Remove debris around outdoor units for proper airflow.
• Reset the System: Switch the unit off at the breaker, wait 30 seconds, and restart to clear minor electronic faults. If error codes persist, log the code number for technician reference.
• Monitor Drain Pan and Lines: Check for pooling water around the indoor unit. Pour a small amount of water into the drain pan to confirm the condensate line is clear.
