Heil Heating and Cooling is a company that specializes in the manufacture of air conditioners, gas furnaces and heat pumps. The company offers a wide range of products, from entry model and horizontal air conditioner units to fan coils.
As of February 2015, all Heil air conditioners, furnaces and heat pumps either meet or exceed current Department of Energy standards for minimum efficiency. These products also exceed standards for the Environmental Protection Agency's ENERGY STAR program. This translates to savings for owners, as the equipment requires less energy to operate and helps promote environmental awareness. Each specific model has its own efficiency rating.
