After living in their lake house for 13 years, it was time for our parents to replace their Heating plus Air Conditioning system. I saw them spend a lot of time researching numerous heat plus air equipment, trying to find the best option, my dad even spoke on the PC with at least 3 strange Heating plus Air Conditioning professionals about their situation. There’s no telling how several more he called when I wasn’t around. When I asked them what they were planning to do, they said they had several options. They could either replace both their oil furnace plus cooling system separately, which was considered their central Heating plus Air Conditioning system, or they could install a heat pump. I didn’t believe what the difference was, so our dad explained it to myself and others in simple terms. In a central Heating plus Air Conditioning system, the cooling system was responsible for cooling, while the oil furnace was responsible for heating, neither the cooling system or oil furnace could do the opposite, for instance, an cooling system could only cool plus a oil furnace could only heat. A heat pump could do both heat plus cool. My dad showed myself and others pictures of both the outside units for a central Heating plus Air Conditioning system plus a heat pump plus I couldn’t tell the difference. They looked legitimately similar! I asked him if there was a difference in energy or efficiency plus he assured myself and others that there wasn’t. They currently had a central Heating plus Air Conditioning system, so they were leaning toward keeping the existing system plus just updating it. My dad thought it would be easier.
