Knowing how to troubleshoot these issues can help ensure your heat pump is functioning properly and effectively.
A heat pump is a device that transfers heat from one location to another. It works by using refrigerant to absorb heat from the outside air, ground, or water source and then compressing and circulating it through a closed loop system. The heat is then released inside the home, providing warmth during colder months. During the summer months, the process is reversed, and the heat pump removes warm air from the inside of the home and releases it outside, providing cool air. In essence, a heat pump allows for efficient heating and cooling by transferring heat rather than generating it, making it an energy-efficient option for homeowners.
