DID OUR HEAT PUMPS SURVIVE THEIR FIRST WINTER?

EV Channels Review

This video provides a comprehensive, albeit slightly delayed, review of the performance of two Mitsubishi heat pump systems installed in the reviewer's home over their first winter. While the systems performed well during the summer, the winter revealed several issues, including units overheating and exceeding set temperature limits, leading to higher-than-expected electricity bills. These problems were traced to a software bug in the Mitsubishi units and issues with temperature sensing, partly due to filter maintenance and a specific modification required for the home's unique setup. The reviewer also notes that other home-related electrical issues and a wife's extensive use of a high-wattage fan heater in her workshop contributed to the increased energy costs. Despite these initial challenges, after professional adjustments and fixes, the heat pump experience has improved significantly, with lower electricity bills and a more comfortable home environment. The reviewer highlights the quiet operation, improved comfort, reduced pest entry, and reclaimed electrical panel space as key benefits, ultimately deeming the heat pump system a 'win'.
