For more than a century, American Standard has built heating and air conditioning products known for quality, reliability and durability. You'll rest easy all winter long knowing that an American Standard gas furnace provides the warmth needed to maintain a pleasant temperature in your home.

If you want your home to be perfectly warm in the winter and perfectly cool in the summer, you need an American Standard heat pump. In the winter, the Heritage heat pump captures the heat that is always present in the outside air - even in the coldest of weather - and pumps it into your home. In the summer, it's an air conditioner, pulling the heat out of your home and releasing it outdoors.

American Standard heat pumps enjoy high Seasonal Energy Efficiency Ratings (SEER) and high Heating Seasonal Performance Factors (HSPF).
