Reliable, High-Quality Mini Split Repair That Restores Comfort Fast

Mini Split Repair and Foxborough MA’s Trusted Heating & Cooling Professionals — Your Local Experts

Mini Split Repair begins with a precise diagnostic: we read system error codes, verify thermostat and sensor (thermistor) performance, check electrical connections and communication wiring between indoor and outdoor units, test fan motors and capacitors, assess refrigerant charge and look for leaks, clean coils and filters, clear condensate drains, and evaluate the inverter board, compressor, and airflow. This process quickly resolves common issues like no cooling or heat, weak airflow, hot/cold spots, short cycling, water leaks, frozen coils, unusual noises or odors, and inconsistent temperatures. Beyond repairs, SumZero Energy Systems offers a full range of services—new mini split and heat pump installations, system replacements and upgrades, seasonal maintenance and tune-ups, multi‑zone design, smart thermostat and zoning solutions, and indoor air quality improvements—delivered with exceptional service and quality craftsmanship. Our friendly technicians explain options clearly, work neatly, and focus on getting your comfort back fast, proudly and professionally serving the Foxborough, MA area.
