The Deluxe wall-mounted single-zone system with H2i plus technology from Mitsubishi Electric Trane HVAC US comprises both a new indoor unit and a new outdoor unit. According to the manufacturer, the wall-mounted indoor unit has a high-performance coating that limits particle build-up on the heat exchanger, which reportedly helps maintain efficiency and reduce maintenance. The outdoor unit is equipped with inverter technology, which the maker says modulates to maintain a consistent indoor temperature and provides 100% heating capacity at outdoor temperatures as low as 5°F and upward of 76% capacity at -13°F. metahvac.com
