Heat pumps offer an energy-efficient alternative to conventional heating and cooling systems and can provide up to 100 percent of your heating and cooling needs. They work by drawing heat from the environment and moving it indoors to heat your home in the winter or moving it outdoors to cool your home during the summer months. A standard electric water heater providing domestic water heating in a situation where the heat pump can not, delivers heat at a COP of 1.0. If that energy was instead attained through an air-to-water heat pump, it could be delivered at a COP averaging perhaps 2.5 over the year.

It is important now to point out that we are only talking about a furnace today, not a heat pump. If you have a heat pump, or are unsure of which your system is, first take a look at: Heat Pump vs Furnace. A furnace works by a very simple principle, it uses some type of fuel (i.e. electrical, oil, gas, etc) to heat a series of coils.
And, again, a lack of warm air blowing over the coil will lead it to freeze. The heat pump is running low on refrigerant – When the refrigerant is low, your system’s pressure will drop, which causes the coil to grow colder than usual. This is the most common source of frozen coils.
