You can still own a heat pump system, no matter if you live in the north. A heat pump system moves heat energy in the air quality, but if you want cooling, the heat energy pushed is then taken outside. If you want heating, the heat energy outside is pushed into the home. The problem is that the heat pump can’t task if there is no heat energy to pump. If the weather gets to around forty degrees, you are getting no heating. In the north I experience rapidly increasing temperatures as low as -20, and the majority of people in the north assumed that the energy efficiency of a heat pump would never be for them; Heating, Ventilation, and A/C companies really came up with a system to allow us to have half the efficiency. During the summer time our brand new home uses a heat pump system to supply cooling. It is very efficient since no A/C is really being produced. The overall air quality is quite clean because of the fresh air being cycled. In the Winter I can’t utilize a heat pump, I need to use a gas furnace. The gas oil furnace and electric heat pump task right with each other in a system. This is called a dual fuel system. The dual fuel system automatically picks up on when to change from electric to gas. It is the most efficient option for having a heat pump in the north. Without any doubt, having a gas furnace is not the ideal, although I still get a heat pump half the year. A few winters I can even use the heat pump for heating, when a cold front comes in to town, I bring in the gas heater.
