Many homeowners in our area enjoy the dual benefit a heat pump HVAC system offers: the ability to both heat and cool your home. It’s understandable how a heat pump cools because in cooling mode, it works just like an air conditioner. However, it can be hard to understand how the system heats. After all, it doesn’t generate heat like a furnace does. The experts at Schaal Heating and Cooling specialize in heat pump services, so let us take a moment to give you a basic overview of how a heat pump provides heat to your home during the winter months.
It’s All About the Air
Believe it or not, the outdoor air always contains heat, even when it’s chilly outside. It just holds a lot less heat at 35 degrees than it does at 75 degrees. Heat pumps work by transferring heat from one location to another. They are able to do this because they use refrigerant to facilitate this transfer. Refrigerant is a chemical that has different boiling points; it also changes states depending on temperature. This is why refrigerant is so useful in a heat pump system.
During the winter, a heat pump system absorbs the available heat in the surrounding outdoor air. This heat is then transferred to the heat pump, where it is concentrated. Once it reaches the right level of pressure, the heat is dispersed to your home, via ductwork or ductless indoor blowers. The heat pump continues this cycle to heat your home.
Why Consider a Heat Pump HVAC System?
Aside from being able to offer both heating and cooling, heat pump systems are very energy efficient. They typically use only 25-50% of the electricity that a traditional AC uses, and they use no fossil fuels whatsoever. They also last longer than traditional heating systems, averaging lifespans of 20-25 years.
