    Ductless Mini Split Repair in NYC & Long Island

    Mini splits cool offices, shops, server rooms and apartments across the city. When one stops working, Com+ Mechanical diagnoses and repairs ductless systems from every major brand.

    Common Mini Split Problems

    Not cooling or heating

    Low refrigerant, a dirty coil, a failed sensor or an outdoor unit fault.

    Water leaking from the indoor unit

    A clogged drain line, failed condensate pump or iced coil.

    Blinking lights or error code

    The system has logged a fault — we read and test the cause.

    Bad smell

    Mold or debris on the coil or blower wheel.

    Unit turns on and off

    Sensor, board or refrigerant problems.

    Ductless systems fail for a short list of reasons: refrigerant leaks, clogged drains, dirty coils, failed boards or sensors, and communication faults between indoor and outdoor units. We read the error codes, test the system and give you written repair options before work starts.

    Frequently Asked Questions

    Get answers to common questions about our services

    Do you repair ductless mini splits in NYC?

    Yes. We repair single-zone and multi-zone mini split systems for commercial and multifamily buildings across NYC and Long Island.

    Why is my mini split leaking water?

    Usually a clogged drain line, a failed condensate pump or a frozen coil. We clear the cause and check why it happened.

    Why is my mini split blinking?

    Blinking lights mean the system has logged an error code. The code points us to the fault, which we then test before replacing parts.

    Should I repair or replace my mini split?

    Most single-part failures are worth repairing. Older systems with compressor failure or repeated leaks are often better replaced. We give you both options in writing.
