Reliable, High-Quality Mini Split Repair That Fixes Issues Fast and Restores Your Comfort

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

Mini Split Repair from SumZero Energy Systems begins with precise diagnostics: we listen to your concerns, read error codes, inspect indoor and outdoor units, verify airflow and temperatures, test electrical components, and measure refrigerant pressures to pinpoint the problem. We quickly resolve common issues such as weak cooling or heating, refrigerant leaks, frozen coils, clogged filters, drainage blockages, sensor or thermostat faults, blower or condenser fan failures, control board or communication errors, unusual noises, and unpleasant odors. Once identified, we deliver targeted fixes—sealing leaks and recharging refrigerant, replacing motors, capacitors, or thermistors, cleaning coils and drains, recalibrating controls, and optimizing system settings—then perform a full test to ensure reliable performance. Our full-service capabilities include new mini split and heat pump installations, system replacements and upgrades, preventative maintenance and tune-ups, indoor air quality solutions, smart thermostat integration, zoning and efficiency optimization, fast emergency repairs, and support for both residential and light commercial needs. Expect exceptional service, quality craftsmanship, transparent pricing, and clear communication from start to finish.
