CROSS REFERENCE TO RELATED PATENT APPLICATIONS 
   This application claims the benefit of U.S. Provisional Application No. 60/884,261, filed Jan. 10, 2007. 

   BACKGROUND 
   The present application relates generally to a bracket for a HVAC system and more specifically to a bracket configured to mount to a door on a HVAC and to secure wiring within the HVAC. 
   The basic components of a typical furnace or HVAC system are: a burner, a heat exchanger, an air distribution system, and a vent pipe. The burner utilizes gas (natural or propane) or oil to generate heat. The heat exchanger transfers the heat from the burner to the air distribution system. The air distribution system, which includes a blower and ductwork, delivers the heated air throughout the home (or other enclosed space) and returns cooler air to the furnace to be heated. Finally, the vent pipe, or flue, exhausts byproducts of combustion in the burner (such as water vapor and carbon dioxide) outside of the home or enclosed space. In addition, the HVAC system may also include a cooling element, such as an A-coil, that operates in conjunction with an air conditioning unit to provide cooled air to the home instead of heated air, when so desired. The size of the A-coil is directly related to the efficiency rating of the system. 
   Typically, furnace systems in residential applications are located in the basement or a small closet in the user&#39;s home, which areas have limited space for an installed furnace system. Furthermore, efficiency standards have recently changed, thereby requiring the size of the A-coil to be increased to meet these new standards. Thus, when a newer furnace system is needed to replace an older system, often, the newer furnace can not fit into the space where the old furnace was installed because the size of the furnace unit and the newer, taller A-coil that is required is greater than the available installation space. Thus, a shorter, furnace is needed to accommodate the taller A-coil in order to be able to install a new furnace system in the same space as the old furnace system. 
   Each individual HVAC or furnace system has separate requirements for the door panel, depending on the requirements of the system. In addition, every HVAC system has a plurality of wires that are routed throughout the system. What is needed is a system or method of a door bracket that will facilitate a variety of door panels to be mounted to the HVAC system housing and contain and route the wires for the system as well. 
   Intended advantages of the disclosed systems and/or methods satisfy one or more of these needs or provides other advantageous features. Other features and advantages will be made apparent from the present specification. The teachings disclosed extend to those embodiments that fall within the scope of the claims, regardless of whether they accomplish one or more of the aforementioned needs.

   DETAILED DESCRIPTION 
     FIG. 1  shows an exemplary HVAC or furnace system  100  in a typical residential setting R. Further,  FIG. 2  illustrates an exemplary HVAC or furnace system  100  having an enclosure  196  with a door panel  198 . The door panel  198  allows access to the internal portion of the furnace system  100 , described in detail below. 
     FIG. 3  shows a schematic arrangement of the internal portion of the furnace system  100 . During operation, a burner  101  combusts fuel with combustion air  102  and provides combustion products and heated air to a first heat exchanger  103 , where heat is transferred to a supply air  104 . Supply air  104  is air that is to be heated, such as interior air for a building HVAC system. Combustion air  102  is then directed into a second heat exchanger  105 , where heat is exchanged with supply air  104 . Supply air  104  is directed over first heat exchanger  103  and second heat exchanger  105  by use of a blower  107  or similar air-moving device. Combustion air  102  is then exhausted from the system  100  by use of an exhaust blower  109  or other air-moving device. Exhaust  111  includes air, water vapor and other combustion products. Furnace system  100  provides heat to supply air  104  by use of first heat exchanger  103  and second heat exchanger  105 . Supply air  104  is than provided to a space for heating. 
   An exemplary embodiment of the disclosed door panel bracket  200  as applied to a furnace or an HVAC system  100  is shown in  FIG. 4 . While reference to an HVAC system  100  is used in this application, it is known by those skilled in the art that the door panel bracket may be used in a furnace system as well. The exemplary door panel bracket  200  is a single unitary piece. It is known by those of ordinary skill in the art that the bracket  200  may not be a unitary piece, and may be several smaller pieces connected together to form a larger piece. The door panel bracket  200  extends across the entire width of the door panel opening  195 . The door panel bracket  200  may be placed at the top of the door panel opening  195 , the bottom of the door panel opening  195 , or anywhere in between. However, the exemplary embodiment shows the door panel bracket  200  in the center (lengthwise) of the door panel opening  195 . 
   The door panel bracket  200  helps to secure different types of door panels  198  to the enclosure  196 . The door panel bracket  200  has one or more first fastener areas  202  that can accommodate door panels  198  that use ¼ turn fasteners, or any other suitable fasteners. The door panel bracket  200  also has one or more second fastener areas  208  that accommodate door panels  198  that use screws or other similar fastening devices. Depending on the door panel type used for the HVAC system, only one (the one or more first fastener area  202  or the one or more second fastener area  208 ) fastener area  202 ,  208  is used at a time. By incorporating the two fastener areas  202 ,  208  into the same door panel bracket  200 , the HVAC system  100  can accommodate different types of door panels  198 . It is to be understood that while one configuration and arrangement of both the first fastener areas  202  and the second fastener areas  208  is shown in  FIGS. 4-8 , other configurations and arrangements of the first fastener areas  202  and the second fastener areas  208  could also be used. Further, the exemplary embodiment illustrates two first fastener areas  202  and two second fastener areas  208 , however, any suitable number of first and second fastener areas  202 ,  208  may be used. 
   In addition, as shown in  FIG. 4 , the door bracket  200  also has a wire retention area  212  incorporated into the bracket  200 . The wire retention area  212  is located in the front of the bracket  200  near the door, but could alternatively be located opposite the door at the back of the bracket  200 . The placement of the wire retention area  212  in the front of the bracket  200  permits the wiring in the HVAC system  100  to be sealed or restrained in a simple and accessible manner. The wire retention area  212  allows the at least one wire routed within to be sealed properly while providing a simple and easy removal of the wire from the HVAC system if necessary. 
   Now referring to  FIG. 5 , a closer look at the door bracket  200  illustrates the wire retention area  212  in relation to the first fastener area  202  and the second fastener area  208 . An exemplary wire retention area  212  is an aperture in the door bracket  200 . At least one wire, or a plurality of wires  214 , are placed through the aperture and are contained within the aperture to prevent them from separating or tangling. All edges of the wire retention area  212  are rounded or provided in such a way that the wires are not exposed to sharp edges that might cut the wires. In the exemplary embodiment, the first fastener area  202  provides the capability to fasten the door bracket  200  from the top surface  216 , and the second fastener area  208  provides the capability to fasten the door bracket  200  from the side surface  218 . 
     FIGS. 6-8  illustrate the top, side, and bottom views, respectively, of an exemplary embodiment of the door bracket  200 . The wire retention area  212  is shown as being disposed in the front of the door bracket  200 , however, the wire retention area  212  may be disposed in the back of the door bracket  200 . The wire retention area  212  may also be disposed on the opposite end of the door bracket  200  than is shown in the figures. The exemplary embodiments illustrate two each of the first fastener area  202  and the second fastener area  208 , however, more first and second fastener areas  202 ,  208  may be used if desired.
