Living where I do a heat pump is the best possible system.
With a heat pump system you get both heating and cooling in a single unit.
The device works by moving heat energy either inside or outside of the home. It acts as an air conditioner in the summer by moving air through coolant. The reverse happens in heating mode. You don’t need to burn and churn fuel. You don’t need to install ductwork. All it takes is an outdoor air compressor and multiple mounted indoor air handlers. The devices are installed on exterior walls and wiring and refrigerant tubes are fed to the outdoor unit. The way a heat pump provides climate control is quite efficient. It is also clean and environmentally friendly. In fact, it is recognized to be so beneficial that the government offers tax benefits when you rely on a heat pump system. The only con is that the heating mode struggles to be effective in temperatures below forty degrees. At this point there is simply no heat energy to locate and move indoors. In colder climates people rely on dual fuel or hybrid heaters which combine a heat pump and a furnace. The heat pump works most of the year and the furnace tags in when the temperatures drop. Thankfully where I am at I can just get with a heat pump system. After a few months of use the heat pump quickly pays back itself. I feel it is the most cost effective heating and air conditioning system on the market at this point.
