Mini-Split System Repair

Service Overview

Mini-split systems are common in NYC apartments and multi-zone setups. Failures often appear as poor cooling, non-responsive remotes, or flashing error codes.

We provide full system diagnostics and repair — both indoor evaporator units and outdoor condenser units.

• No cooling or reduced airflow
• Remote not syncing or no response
• Flashing error codes on display

• Dripping or leaking water from wall unit
• Outdoor unit not turning on or cycling repeatedly
• Inverter board or sensor malfunction
• Communication fault between indoor and outdoor modules

Diagnostic Process

• Check voltage and wiring continuity
• Test refrigerant pressure and compressor function

Not cooling properly? Don't guess. Mini-splits require targeted diagnostics — we bring the tools.
