The most efficient heating and cooling system available. Both single and two-speed models provide your family with safe, clean and reliable heating, cooling and domestic assist water heating...all from the same highly efficient unit. Two-speed models operate on low speed about 80 percent of the time and only shift into high speed when temperatures are extreme. With two-speed operation, you not only save money, but the lower airflow and reduced cycling enhances your family's comfort even more.
