It is a struggle deciding if I am more irritated with my Heating and Air Conditioning contractor or myself, but on a single hand, I was an idiot with buying my heat pump. On the other hand, my Heating and Air Conditioning professional sold myself and others a Heating and Air Conditioning idea that he knew for a fact that I could not use. A heat pump idea is a 2 for a single system. You get both heating and air because the heat pump simply moves heat energy inside or outside. If you want cooling, the heat energy is pumped outdoors. The reverse is for heating. However, I live in the north where the rapidly changing temperatures get in the disadvantage twenties. When it gets that cold, you have no heat energy to pump to deliver heating. The heat pump is a worthless furnace for myself and others and the Heating and Air Conditioning contractor totally knew when he sold it to me. A heat pump is fancy though, so the guy got a high commission rate. But, I should have done the research; Everything online warns you that a heat pump cannot deliver heating after the rapidly changing temperatures drop below forty degrees. There are a couple people in the north with heat pumps. They only use the idea for the cooling function though. You save quite a bit of money using a heat pump. It does not have to create the cold air, it just pushes the air around. But, the heat pump has to be paired with a oil furnace for the wintertime. Buying a oil furnace to add to the heat pump is fancy. It is called a dual fuel idea and I am just not willing to do this.
