         7 . The refrigeration coil and drain pan assembly of  claim 1 , wherein at least one of the first drain pan and the second drain pan comprises at least two levels. 
     
     
         8 . The refrigeration coil and drain pan assembly of  claim 1 , wherein the refrigeration coil is a dedicated horizontal refrigeration coil. 
     
     
         9 . The refrigeration coil and drain pan assembly of  claim 1 , wherein the refrigeration coil is configured for an airflow to enter the refrigeration coil from a specific direction. 
     
     
         10 . The refrigeration coil and drain pan assembly of  claim 1 , wherein the refrigeration coil has an open end and a converged end and an airflow enters the refrigeration coil at the open end and travels in a direction towards the converged end. 
     
     
         11 . An HVACR unit, comprising:
 a blower driving an airflow, and   a refrigeration coil and drain pan assembly, located downstream of the blower with respect to the airflow, wherein the refrigeration coil and drain pan assembly comprises:
 a first drain pan having one or more drain connections, 
 a second drain pan having one or more drain connections, and 
 a refrigeration coil comprising a plurality of fins, the fins oriented in a direction between the first drain pan and the second drain pan, and 
 a refrigerant line, exiting the refrigeration coil and drain pan assembly on a side; 
 wherein the first drain pan is located opposite the second drain pan with respect to the refrigeration coil. 
   
     
     
         12 . The HVACR unit of  claim 11 , wherein the refrigeration coil and drain pan assembly is oriented such that one of the first drain pan and the second drain pan is located at the bottom of the refrigeration coil and drain pan assembly. 
     
     
         13 . The HVACR unit of  claim 11 , wherein the refrigeration coil has an open end and a converged end and the airflow enters the refrigeration coil at the open end and travels in a direction towards the converged end. 
     
     
         14 . The HVACR unit of  claim 13 , wherein the refrigeration coil and drain pan assembly is installed in one of:
 a first position where airflow through the refrigeration coil and drain pan assembly is from left to right from the perspective of the side of the refrigeration coil and drain pan assembly where the refrigerant line leaves the refrigeration coil and drain pan assembly, or   a second position where airflow through the refrigeration coil and drain pan assembly is from right to left from the perspective of the side of the refrigeration coil and drain pan assembly where the refrigerant line leaves the refrigeration coil and drain pan assembly, and   
       wherein the refrigeration coil and drain pan assembly may be switched from the first position to the second position. 
     
     
         15 . The HVACR unit of  claim 11 , wherein the refrigeration coil and drain pan assembly further comprises a removable access door disposed on a side of the refrigeration coil and drain pan assembly where the refrigerant line exits the refrigeration coil and drain pan assembly. 
     
     
         16 . The HVACR unit of  claim 11 , wherein at least one of the first drain pan and the second drain pan comprises at least two levels. 
     
     
         17 . The HVACR unit of  claim 11 , wherein the refrigerant line exits the refrigeration coil and drain pan assembly at a point equidistant from the first drain pan and the second drain pan. 
     
     
         18 . The HVACR unit of  claim 11 , wherein the first drain pan and the second drain pan are parallel to one another.
