Combining a 14 SEER air conditioning unit with an appropriately sized 80%+ AFUE natural gas furnace, these units can keep your home cool in the summer and warm in the winter. The Goodman GPG14 series of all-in-one packaged units sit entirely outdoors and connect to your existing ductwork. At 14 SEER these units are great for people who are more concerned with up-front costs than long-term total cost of ownership or who don't need a lot of cooling year-round. All of these Goodman units come fully charged and tested, making for quick and easy installation by a professional.
