My wife and I live in the northeastern section of the country, and we worry about keeping warm in the winter. Our weather often turns cold enough to require our heating our home as early as September. Sometimes the cold weather hangs around until April. The outside temperatures often drop below zero, and the windchill makes it feel a lot colder. I have a furnace installed in the house which can handle the coldest of winter. It does, however, cost a king’s ransom to operate during those cold spells. Although our summertime is typically short, it often can get extremely hot . We both got tired of living in a overheated, sticky house so I contacted a reliable HVAC technician about installing a central cooling system. He recommended installing an electrical heat pump instead. This actually sounded ludicrous to me and my wife, since we already have a good furnace heating system in the house. I figured he just wanted me to spend more money on a heat pump, so his commission would be higher. The HVAC contractor explained that in the hot summer months the heat pump would act like a central air conditioner, and it would cost less to operate it. When the weather turned cooler, the heat pump would then operate as my heating system. When the outside temperatures dropped below freezing the heat pump would become ineffective and the furnace would automatically take over. The benefit to us is that a heat pump is far more power efficient than my existing furnace and additionally would significantly trim monthly energy bills. It would also save my furnace from excessive wear, helping it to last longer. The overall cost savings of combining heat pump with the furnace should recover the investment in this system in a very short time.
