Heating and cooling account for the largest energy use in a typical home. Why is everyone going to need a heat pump? In this seminar this question will be addressed because heat pumps are a two-way solution for year-round home comfort. They are a cost-effective and energy-efficient, climate-friendly solution for heating and air conditioning buildings.

Heat pumps are different than our traditional HVAC systems in several ways. First, heat pumps operate in both a heating and cooling mode, thus replacing roles of an air conditioner and a furnace. Second, they are our best opportunity to phase out fossil fuels for heating, and third, heat pumps are much more energy efficient. The principle is simple, heat pumps move heat from outside to the indoors during the heating season and just the opposite, move heat from the indoors to the outside during the cooling season. Because the heat pump moves heat rather than generating heat the energy used is greatly reduced.

Steve Erdman (part-time pediatrician) and his wife Terri joined Academy Village in January of 2022 moving into their sixth home on Langtry Lane. They recently replaced both original faltering HVAC units with heat pumps. Home improvement projects are mental therapy for Steve who works to be an educated, environmentally responsible consumer and homeowner.
