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

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

When your ductless mini split isn’t performing, SumZero Energy Systems gets you comfortable again—fast. Our certified technicians begin with a thorough diagnostic: we listen to your concerns, check error codes, inspect indoor and outdoor units, measure refrigerant pressures, test electrical components, verify airflow, and ensure the condensate system drains properly. We quickly identify and resolve common issues such as weak heating or cooling, refrigerant leaks, dirty filters or coils, frozen evaporators, sensor or thermostat faults, clogged drain lines and water leaks, noisy or failing fan motors, compressor or capacitor problems, short cycling, and tripped breakers. Repairs are precise and efficient—coil cleanings, filter replacements, leak detection and sealing with proper recharge, control board or sensor repair, condensate clearing, motor or capacitor replacement, electrical tightening, and final performance calibration to manufacturer specs. Beyond repairs, we offer complete solutions: new and replacement mini split installations (single- and multi-zone), heat pump systems, seasonal tune-ups and maintenance plans, indoor air quality improvements, and smart control integrations.
