  • Warranty Coverage
  • Straight from the manufacturer, this unit comes with a 5-year parts warranty and a 7-year compressor warranty. However, by ensuring installation adheres to state and local codes and registering the unit online through Mitsubishi, you can enjoy an extended 10-year warranty covering both parts and the compressor.

  • Home Comfort at It’s Best

For added convenience, consider the Mitsubishi Kumo Cloud, a branded WiFi mini-split adapter, allowing remote control from anywhere with an internet connection.
  • Mitsubishi Diamond Contractor Installation
  • Designed as a compact version of an all-electric central heat pump system, the Mitsubishi SEZ model mini-split is a space-saving alternative. It fits snugly into smaller spaces like ceilings or walls, eliminating the need for a dedicated closet. While its output is lower than many central systems, it can be used in tandem to cover larger areas based on your home’s specific needs. The unit can be configured to blow air directly into a space with the appropriate mounting equipment or through ductwork, enabling you to direct airflow into individual rooms or multiple spaces, making it adaptable for various installation scenarios.
