 a housing having an exterior and an interior, the interior comprising a plurality of compartments, wherein the interior comprises:
 an energy recovery ventilator configured to transfer heat and moisture from a first air stream to a second air stream; and 
 an air conditioning system comprising a condenser, compressor, and evaporator, wherein the air conditioning system includes a plurality of refrigerant lines containing pre-pressurized refrigerant, and wherein the air conditioning system has a capacity from 1000 to 4000 BTUs. 
   
     
     
         2 . The system of  claim 1 , wherein the air conditioning system has a capacity of about 3000 BTUs. 
     
     
         3 . The system of  claim 1 , wherein the plurality of compartments includes a first compartment having the energy recovery ventilator therein, and a second compartment having the air conditioning system therein, wherein the first compartment and second compartment are isolated. 
     
     
         4 . The system of  claim 1 , further comprising at least one exhaust fan located external to the housing and configured to generate at least one exhaust air stream directed toward the housing. 
     
     
         5 . The system of  claim 4 , further comprising one or more ducts having a first end being connected to the at least one exhaust fan and a second end being connected to the housing, and configured to direct the exhaust air stream from the at least one exhaust fan to the housing. 
     
     
         6 . The system of  claim 5 , further comprising an exit vent disposed about an exterior wall adjacent to an outdoor environment for venting the exhaust air stream to the outdoor environment, and wherein one or more ducts are connected between the housing and the exit vent configured to direct the exhaust air stream to the exit vent. 
     
     
         7 . The system of  claim 1 , further comprising at least one intake fan located internal to the housing and configured to generate at least one intake air stream. 
     
     
         8 . The system of  claim 7 , further comprising one or more ducts connected on a first end to the housing and a second end connected to an intake vent disposed about an exterior wall adjacent to an outdoor environment for intake of air from the outdoor environment. 
     
     
         9 . The system of  claim 1 , wherein the first air stream or the second air stream, but not both, is an intake air stream, the intake air stream directed through the energy recovery ventilator such that heat and moisture transfer to the intake air stream, and wherein the intake air stream contacts the evaporator and then is supplied through a supply vent into the interior room of the dwelling. 
     
     
         10 . The system of  claim 3 , wherein the first compartment contains sub-compartments for isolating the first air stream from the second air stream. 
     
     
         11 . An air circulatory system for supplying conditioned air to an interior room of a dwelling, the system comprising:
 a central unit having a plurality of components comprising an energy recovery ventilator, an evaporator, a condenser, a compressor, and wherein the central unit has a controller communicatively associated with one or more of the plurality of components;   wherein the controller is configured to operate the air circulatory system in a plurality of modes of operation wherein the controller selectively operates one or more of the components.   
     
     
         12 . The system of  claim 11 , wherein the mode of operation is selected by a user. 
     
     
         13 . The system of  claim 11 , wherein the mode of operation is determined by the controller based on one or more inputs to the controller. 
     
     
         14 . The system of  claim 13 , wherein the one or more inputs to the controller include at least one of temperature or humidity, or both, and wherein the temperature or humidity may be sensed from the interior room of the dwelling, or from an outdoor environment outside of the dwelling, or both. 
     
     
         15 . The system of  claim 11 , wherein one mode of operation of the plurality of modes of operation includes operating the energy recovery ventilator to the exclusion of the evaporator, condenser, and compressor. 
     
     
         16 . The system of  claim 11 , wherein one mode of operation of the plurality of modes of operation includes operating the evaporator, condenser, and compressor to the exclusion of the energy recovery ventilator. 
     
     
         17 . The system of  claim 11 , wherein one mode of operation of the plurality of modes of operation includes operating the energy recovery ventilator, the evaporator, the condenser, and the compressor. 
     
     
         18 . The system of  claim 11 , wherein one mode of operation of the plurality of modes of operation includes operating the energy recovery ventilator for a first length of time, and operating the evaporator, the condenser, and the compressor for a second length of time, wherein the first length of time and the second length of time overlap. 
     
     
         19 . The system of  claim 11 , further comprising one or more sensors for sensing a parameter which may be provided to the controller, wherein the one or more sensors may sense at least one of temperature or humidity, or both. 
     
     
         20 . The system of  claim 11 , further comprising a user interface that is communicatively linked to the controller, wherein a user may provides inputs to the user interface for selecting one or more modes of operation of the plurality of modes of operation.
