Choosing a Merit heat pump
Merit is Lennox's entry line. The ML14KP1 runs at full output whenever it's on, which keeps it simple for a straight replacement.
A heat pump cools in summer and heats in winter. Pair it with a Lennox air handler, or with a gas furnace and coil for a dual-fuel setup. For variable speed, compare Lennox Elite heat pumps.
