Common Mini Split Problems

• Refrigerant Leaks
  • ‍Signs: Reduced cooling capacity, hissing sounds near lines, ice formation on evaporator coils. ‍
  • Impact: Low refrigerant levels force the compressor to work harder, increasing energy consumption and risking compressor damage. ‍
• Frozen or Dirty Coils
  • ‍Signs: Frost buildup on indoor unit, system cycles on and off, insufficient airflow. ‍
  • Impact: Compromised heat transfer leads to poor efficiency, potential coil corrosion and water leaks when ice melts. ‍
• Drain-Line Clogs & Water Leaks
  • ‍Signs: Pooled condensate under the indoor unit, musty odors, overflow alarms. ‍
  • Impact: Water damage to walls and ceilings, mold growth and degraded indoor air quality. ‍
• Fan Motor or Capacitor Failures
  • ‍Signs: Loud humming, intermittent operation, complete airflow loss. ‍
  • Impact: Without proper airflow, heat exchange is disrupted and system shutdowns become more frequent. ‍
• Electrical Issues
  • ‍Signs: Tripped breakers, flashing LEDs on the control board, unresponsive remote or thermostat. ‍
  • Impact: Untreated electrical faults can lead to burned-out components or system lockouts. ‍
• Sensor & Thermostat Malfunctions
  • ‍Signs: Inaccurate temperature readings, random on/off cycles, inability to maintain setpoint. ‍
  • Impact: User discomfort, energy waste and unnecessary wear on system components.

Our Diagnostic Process

• System Inspection & History Review: We begin by reviewing your unit’s service history, age and any prior repairs. A preliminary visual inspection checks for obvious damage or leaks.
• Pressure Testing & Leak Detection: Using dry-nitrogen pressure tests and advanced electronic leak detectors, we pinpoint hidden refrigerant leaks in lines and connections.
• Airflow & Filter Examination: Proper airflow is crucial. Filters, coils and blower wheels are inspected and cleaned as needed, ensuring unobstructed air movement.
• Electrical Component Testing: Voltage and continuity tests on capacitors, contactors and circuit boards verify stable power delivery. Breaker panels and control wiring are also examined.
• Sensor Calibration: Indoor-unit sensors are checked for accuracy. Faulty sensors can be recalibrated or replaced to restore precise temperature control.
• Detailed Repair Plan & Estimate: Once the root cause is identified, we present a repair proposal outlining necessary parts, labor and an estimated timeline—so you know exactly what to expect.

Repair vs. Replace: Making the Right Choice

In McDonald’s climate, a well-maintained mini split can last 12–15 years. When repair costs approach 50% of a new system’s value—or when multiple components fail—replacement may be more economical. We’ll provide a straightforward comparison, factoring in equipment age, repair history and local energy rates to guide an informed decision.
