Mini Split Repair Near Brookline, MA

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

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

At SumZero Energy Systems, our Mini Split Repair begins with a thorough diagnostic to pinpoint the root cause: we measure refrigerant pressures and temperature splits, test electrical components and sensors, inspect coils and filters for buildup, check drain lines and condensate pumps, and verify communication between indoor and outdoor units; this lets us quickly resolve common issues such as refrigerant leaks, frozen coils, clogged filters, drain clogs, sensor errors, capacitor or board failure, short cycling, noisy operation, and poor airflow or hot/cold spots. We seal and test for leaks, recharge refrigerant responsibly, replace failed parts, clean and sanitize coils, clear drains, recalibrate thermostats and remotes, update controls, and perform a full system run test to ensure lasting performance. Beyond repair, we offer complete HVAC solutions: mini split installation and replacement, seasonal maintenance and tune-ups, heat pump services, central AC and furnace repair, ductless zoning, indoor air quality upgrades, and smart thermostat integration—delivered with “exceptional service” and “quality craftsmanship.” Count on our licensed, courteous technicians for clear communication, fair recommendations, and reliable results, proudly and professionally serving the Brookline, MA area.
