Napolean’s NS18 heat pump and air handler is an all-in-one heating and cooling system for year-round comfort—100% heat in the winter and 100% cool in the summer. The heat pump has newer, more efficient technology that features a variable inverter compressor and vapor injection technology to heat a home in temperatures as low as -30°C (-22°F) and cool it on sweltering days as hot as 54°C (129°F) — the widest operating range in the category. It also operates on electricity, helping homeowners reduce their carbon footprint without sacrificing comfort and reducing energy costs, Napolean notes.
