Expert Review: Mitsubishi Electric Mini Splits
Mitsubishi Electric invented the modern mini split and remains the undisputed leader. Their Hyper-Heating INVERTER technology maintains full heating capacity down to -13°F — critical for Long Island's Climate Zone 4A winters. Indoor units operate at just 19 dB, quieter than a whisper. The kumo cloud app provides full remote control and energy monitoring. We are a Mitsubishi Diamond Contractor and have installed thousands of systems across Nassau County. No other brand matches Mitsubishi's combination of efficiency, quiet operation, and cold-weather performance.
