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

At SumZero Energy Systems, Mini Split Repair starts with a precise diagnostic to find the true source of the problem—checking refrigerant pressures and leaks, testing electrical components and sensors, verifying communication between indoor and outdoor units, and measuring airflow. We resolve common issues like low refrigerant, dirty or frozen coils, clogged filters, drain line blockages and water leaks, faulty capacitors, worn fan motors, noisy compressors, thermostat and control board failures, and inverter or communication errors. After identifying the issue, we make targeted repairs, replace worn parts with quality components, clean and recalibrate the system, and confirm performance to factory specifications. Beyond repairs, our full range of services includes routine maintenance and tune-ups, new mini split and heat pump installations, system replacements and upgrades, multi-zone design and retrofits, indoor air quality solutions, smart controls, and 24/7 emergency service. Count on our “exceptional service,” “quality craftsmanship,” transparent pricing, and respectful, on-time technicians. SumZero Energy Systems is proudly and professionally serving the Milford, MA area.
