How does central air conditioning work?

An air conditioning system works by extracting hot and humid air from inside your house and distributing cool air through a duct system. Your central air conditioning system is responsible for keeping your family cool and comfortable throughout the hot summer months.

Most central air conditioning units in Maryland are made up of an outdoor air conditioning unit and an indoor furnace. The alternative is a heat pump system, in which the heating and cooling functionalities are both housed in the outside unit. To better understand when it might be time to replace your AC system and how to go about finding a new one, view our Heating & Air Conditioning Buying Guide.
What are signs that it is time for an AC Replacement?
