    Air Conditioning

    An air conditioner is the outdoor unit that cools air and sends it to the indoor unit for circulation through your home. Indoor and outdoor units are designed to work together. When the air conditioner is properly matched with a furnace or air handler, you get maximum efficiency and longer system life.

    Furnaces

    Furnaces heat and circulate warm air in the winter. Furnace heating ability is measured with an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace.

    Heat Pumps

    A split system heat pump keeps homes comfortable all year long. In summer, it draws heat out of your home to cool it. In the winter, it draws heat from outside air into your home to warm it.

    Packaged Heating and Cooling Systems

    In a packaged system, all equipment is built into an outdoor unit, usually on a concrete slab or other platform. The "package" that gives it its name provides central air conditioning during the summer and heat in colder months.
