Choosing the right type of air conditioning system can be overwhelming, but we're here to make it easy for you. The most common AC system out there is a split system. You probably have one, but don't even know it. The split system has indoor and outdoor components working together to regulate the temperature in the living areas. Refrigerant is compressed in the outside unit, known as a condenser or compressor, and transferred via a copper line to the inside unit, which delivers chilled air to the rooms through a duct system. HVACDirect.com has a large variety of AC systems to choose from. This video will explain the different system available at HVACDirect.com and how to make an educated purchase.
