A drain pan liner usable for preventing condensation in a drain pan having a plurality of elongated interconnect peripheral sides, each elongated side including a moisture guiding surface defined by sidewalls extending therefrom on a top portion of the drain pan and a bottom surface disposed opposite the moisture guiding surface on a bottom portion of the drain pan, the drain pan liner comprising:
 a plurality of foam side lining portions, each foam side lining portion being couplable to an associated bottom surface of the elongated sides of the drain pan to form a condensation barrier along the bottom portion of the drain pan corresponding to the moisture guiding surface; and   an adhesive completely covering a surface of each portion.   
   
   
       6 . The drain pan liner of  claim 5 , wherein the foam side lining portions are contoured to correspond to a substantially convex shape of associated bottom surfaces of the elongated sides of the drain pan. 
   
   
       7 . The drain pan liner of  claim 5 , wherein the foam side lining portions each have an elongated rectangular shape, and a removable cover disposed on the adhesive to protect the adhesive. 
   
   
       8 . The drain pan liner of  claim 7 , wherein said removable cover comprises one of a paper sheet and a plastic sheet. 
   
   
       9 . The drain pan liner of  claim 5 , wherein the lining portions are cross-linked, closed cell polyethylene. 
   
   
       10 . The drain pan liner of  claim 5 , wherein the adhesive is an acrylic. 
   
   
       11 . The drain pan liner of  claim 10 , wherein the plurality of lining parts are defined by contours formed in the foam sheet the contours being raised with respect to a major plane of the foam sheet. 
   
   
       12 . The drain pan liner of  claim 15 , wherein the foam sheet comprises at least one contour extending longitudinally along the foam sheet to define two different lining parts, the at least one contour projecting from a major plane of the foam sheet. 
   
   
       13 . The drain pan liner of  claim 5 , wherein the lining portions are flat. 
   
   
       14 . A drain pan usable to drain moisture from an air conditioning unit, the drain pan comprising:
 a plurality of side panels, each side panel including an upper moisture guiding portion and a lower portion having a surface; and   a plurality of foam lining sheets adhered to said lower surfaces.   
   
   
       15 . The drain pan of  claim 14 , wherein the foam lining sheets are contoured to correspond to the respective bottom surfaces. 
   
   
       16 . The drain pan of  claim 14 , wherein each foam lining sheet is formed from a closed cell, cross-linked polymer. 
   
   
       17 . The drain pan of  claim 16 , wherein the polymer is polyethylene. 
   
   
       18 . The drain pan of  claim 17 , wherein each foam lining sheet has an elongated rectangular shape and an adhesive disposed on a surface thereof. 
   
   
       19 . The drain pan of  claim 18 , further including:
 a drain hole disposed in a sidewall of the top moisture guiding portion, the drain hole eliminating moisture in the side panels of the drain pan.   
   
   
       20 . The drain pan of  claim 19 , wherein the adhesive is a pressure sensitive acrylic. 
   
   
       21 . The drain pan of  claim 19 , wherein each lining sheet is contoured and conforms to the contour of the associated side panel. 
   
   
       22 . The drain pan of  claim 21 , wherein each lining sheet abuts an adjacent lining sheet for thereby covering completely a surface of the drain pan. 
   
   
       23 . A kit for insulating a drain pan, comprising:
 a plurality of foam parts each having a shape that corresponds to an associated portion of the drain pan, each of the foam parts including an adhesive applied along an entire surface thereof and a release sheet disposed on the adhesive, and the release sheet being removable from the adhesive; and   a container for housing the plurality of foam parts.   
   
   
       24 . A method of applying a drain pan liner to a drain pan having a moisture guiding surface and non-moisture guiding surface opposite to the moisture guiding surface, the method comprising:
 providing the drain pan liner which includes a plurality of elongated lining portions to fit the drain pan, an adhesive film disposed on a rear portion of each of the lining portions on the contours, and a release sheet to cover the adhesive film;   peeling a first release sheet of a first elongated lining portion from a first adhesive film to expose the first adhesive film and applying the first elongated lining portion to a first side panel of the non-moisture guiding surface of the drain pan; and   peeling a second release sheet of a second elongated lining portion from a second adhesive film to expose the second adhesive film and applying the second elongated lining portion to a second side panel of the non-moisture guiding surface of the drain pan.   
   
   
       25 . The method of  claim 24 , wherein the providing of the drain pan liner comprises:
 providing a foam sheet including the elongated lining portions defined therein; and   separating the elongated lining portions from the foam sheet.
