Systems we service

• Midea VRF/heat recovery heat pumps (multi-zone, inverter-driven)
• Midea commercial split and multi-split heat pumps
• Packaged rooftop heat pump units serving large floor plates
• Controls, sensors, and BMS integrations related to Midea equipment

When to call for repair

• Inconsistent temperatures, hot/cold spots, or zones that won’t condition
• High energy bills or unexpected demand spikes
• Ice on coils, oil staining, or refrigerant alarms
• Unusual compressor or fan noise, vibration, or short cycling
• Poor ventilation or IAQ complaints from occupants

Addressing these early prevents expensive component failures, protects indoor air quality, and keeps your building compliant and comfortable.

Our diagnostic and repair process

• Step 1 – Site assessment: Review symptoms, application, and recent service history.
• Step 2 – Instrumented testing: Electrical, refrigerant, airflow, and control logic checks.
• Step 3 – Root-cause report: Plain-English findings with prioritized repair options.
• Step 4 – Precision repairs: Component replacement, sealing, calibration, and start-up verification.
• Step 5 – Performance tuning: Balance, setpoint optimization, and documentation.

Typical fixes include inverter and board diagnostics, sensor and expansion device replacement, leak detection and repair, refrigerant charging by weight and subcool/superheat, coil cleaning, airflow balancing, and control sequence adjustments to stabilize capacity and restore efficiency.

Healthy air is our mission

We tune Midea heat pumps to support clean ventilation and optimal filtration, helping reduce pollutants and maintain healthy indoor air—because healthier air at work leads to healthier lives. We verify airflow, check coil and filter condition, and ensure sequences support ventilation requirements without sacrificing comfort.
