The weather in the section where I live is a constant concern. We have fairly short summer season seasons, however the excessive humidity & high uneven temperatures make it impossible to get by without air conditioning. The Winter Times are long & brutal, with uneven temperatures well below zero & dangerous wind chill. The Springtime & fall are unpredictable & rarely mild enough to go without either heating or cooling. Because of relying on temperature control nearly all year round, my daily utility bills are a big area of the budget. To optimize comfort & efficiency, I chose a dual fuel system for my home. A dual fuel system is far more costly to install than most other types of heating & cooling. However, the unit has paid for itself in energy savings. A dual fuel system combines a forced air gas oil furnace with an electric heat pump. During the warmer weather, the heat pump provides air conditioning. It works on the same principle as a refrigerator, simply moving heat from 1 arena to another to create a cooling effect. It is more energy efficient than a conventional air conditioning & achieves superior dehumidification. When the weather starts to cool off, the heat pump reverses direction to bring ambient heat into the house. There is no burning of fossil fuels, eliminating any fear of carbon monoxide poisoning, fumes or tepid surfaces. Plus, there’s no orange house gas emissions, making the system actually environmentally friendly. However, the heat pump can only manage uneven temperatures down to thirty-two degrees. At that point, the oil furnace automatically starts up & handles comfort for as long as necessary. The combination of the heat pump & oil furnace lessens wear & tear on both, leading to longer repair lives & less opportunity of malfunction.
