What to Expect During Your Mini-Split Precision Tune-Up

 

At Pacific Heating & Cooling, we specialize in maintenance for ductless mini-split systems—adapting our process to meet the specific needs of your equipment. Whether your mini-split is used for heating, cooling, or both, our certified technicians provide a comprehensive evaluation to help keep your system running efficiently, reliably, and year-round. Here’s what you can expect:

Detailed Indoor Unit Inspection

Each indoor head will be individually evaluated to ensure optimal performance:

  • Fan Wheel & Blower Condition
    We inspect for dust buildup, debris, damage, or organic growth that can restrict airflow and reduce efficiency.

  • Coil Condition
    We check for cleanliness, damage, or microbial growth that may impact performance or air quality.

  • Condensate Drainage
    We verify drainage integrity—whether gravity-based or pump-assisted—and ensure there’s no risk of leaks or clogs.

  • Filtration Type & IAQ Considerations
    Your technician will identify the current filter type and recommend any upgrades or changes to improve air quality.

  • Temperature & Airflow Readings
    We measure return and supply air temperatures and airflow to calculate BTU performance against system expectations.

Outdoor Unit Check

A healthy outdoor unit is essential to system performance. We inspect for:

  • Condensing Fan & Coil Condition
    We review the fan for wear or growth and inspect coils for debris, corrosion, and general condition.

  • Electrical & Mechanical Stability
    Includes voltage checks, pad stability, and line insulation to ensure safe and effective operation.

  • Drain Termination Location
    We ensure the outdoor unit drains properly and doesn’t risk damage to nearby areas.

Remote Controls & System Settings

We verify that all thermostats or remote controls are functioning and communicating properly with each zone or indoor unit.

Performance Testing

We conduct performance checks to confirm efficiency and identify potential concerns early:

  • Voltage checks across indoor and outdoor components

  • Airflow and temperature differential measurements

  • System cycle testing to verify proper startup and shutoff

  • Heat BTU calculations for each zone (where applicable)

Review, Recommendations & Peace of Mind

After your tune-up, your technician will:

  • Walk you through any findings and explain system status

  • Share recommendations for cleaning, upgrades, or repairs

  • Answer your questions with honest, expert guidance

  • Note your system’s age, condition, and expected lifespan

Our Promise: Every mini-split tune-up includes a transparent evaluation and recommendations—no surprises, no pressure.
