Reliable, High-Quality Mini Split Repair to Solve Issues Fast and Restore Comfort

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

Mini Split Repair starts with precise diagnostics to pinpoint the problem fast—our certified technicians check refrigerant pressures, test electrical components, verify indoor/outdoor communication, inspect coils and filters, and clear condensate drains to resolve issues like weak airflow, uneven temperatures, water leaks, frozen coils, foul odors, short cycling, strange noises, and error codes. We fix it right the first time by sealing leaks and recharging refrigerant, repairing control boards and sensors, replacing blower motors or capacitors, cleaning and sanitizing coils, tightening electrical connections, flushing drain lines, and recalibrating thermostats and remotes, then confirming performance with a full system test. Beyond targeted repairs, SumZero Energy Systems offers a complete HVAC lineup: new ductless and heat pump installations, system replacements, seasonal maintenance and tune-ups, indoor air quality solutions, and efficiency upgrades tailored to your home.
