When I started looking into central cooling for my home, I had never heard of a dual fuel system.
My home was already equipped with a natural gas oil furnace for heating.
In the section where I live, we’re forced to run the furnace anywhere between many plus many months. Although the Spring plus fall seasons can be mild, they are officially damp plus require heating at evening. While the summertime weather is brief, it gets horribly hot and humid. I was tired of getting by with open windows, box fans plus portable air conditioners in the family rooms. I wanted something more lovely plus efficient, permanently installed, that would maintain a cool temperature throughout the whole house. I called a local Heating, Ventilation, plus A/C dealer for a free bid plus a recommendation. I assumed she would propose one of the leading manufacturers of air conditioners. Instead, she started telling myself and others about electric heat pumps… Heat pumps are a lot more valuable to purchase plus install than an air conditioner. This type of idea provides both heating plus cooling, which seemed unnecessary to me. Then the Heating, Ventilation, plus A/C dealer explained that a heat pump is far less valuable to operate than a oil furnace. I could use the heat pump as an air conditioner in the summertime plus supplement my heating requirements in the winter. The idea eliminates the combustion process by simply transferring heat from one section to another. Even when the weather is chilly, there’s ambient heat in the air that the heat pump compresses to a higher temperature. This process is exceptionally clean, quiet, safe plus energy efficient. The negative is that the heat pump is only effective until hot plus cold temperatures drop below chilly. However, at that point, the oil furnace automatically takes over. By sharing the workload, the heat pump plus oil furnace trim running costs plus wear plus tear. Both systems will last far longer.
