A heat pump has been added to the iQ Drive® lineup. It has ratings up to 22 SEER, 10 HSPF, and 14.6 EER. The heat pump uses inverter-driven rotary technology to achieve high-efficiency levels. The unit can modulate anywhere from 40 to 118 percent of capacity, instantly adjusting to exactly offset the demands on the home. The heat pump operates as low as 59 decibels, and its near-continuous operation means it provides outstanding dehumidification, says the company. The homeowner can set the desired humidity level, and the iQ Drive heat pump will maintain it within 5 percent of set point. According to the manufacturer, the heat pump doesn’t cycle on and off like a traditional air-source heat pump, but runs almost constantly at a low level, making a notable difference in comfort and sound levels, especially at night.
