HVAC SYSTEM WITH SEPARABLE HEATER HOUSING

1 . An HVAC system comprising:

an evaporator housing having an evaporator disposed therein; and

a heater housing having a heater disposed therein;

wherein the heater housing is configured to be removably coupled to and supported by the evaporator housing.

2 . The HVAC system of claim 1 , wherein the heater housing is pivotally coupled to the evaporator housing.

3 . The HVAC system of claim 2 , further comprising:

a pin formed on a lower surface of the heater housing; and

a slot formed on an upper surface of the evaporator housing;

wherein the pin is disposed in the slot.

4 . The HVAC system of claim 3 , wherein the heater housing is configured to rotate relative to the evaporator housing about the pin.

5 . The HVAC system of claim 1 , wherein the heater is a PTC heater.

6 . The HVAC system of claim 1 , further comprising a blower housing removably coupled to the evaporator housing and the blower housing.

7 . An HVAC system comprising:

an evaporator housing;

a blower housing; and

a heater housing pivotally coupled to at least one of the evaporator housing or the blower housing;

wherein the heater housing is removably separable from the evaporator housing and the blower housing.

8 . The HVAC system of claim 7 , wherein the heater housing is coupled to at least one of the evaporator housing or the blower housing in a fixed orientation.

9 . The HVAC system of claim 7 , wherein the blower housing is separable from the evaporator housing.

10 . The HVAC system of claim 7 , further comprising a lower attachment mechanism comprising:

a pin extending from one of the heater housing or the evaporator housing; and

a hook extending from the other of the heater housing or the evaporator housing, the hook defining a slot configured to receive the pin therein.

11 . The HVAC system of claim 10 , wherein the pin extends from the heater housing and the hook extends from the evaporator housing.

12 . The HVAC system of claim 10 , wherein the pin is retained in the slot with an interference fit.

13 . The HVAC system of claim 10 , wherein:

the slot defines a first portion extending in a first direction and a second portion extending in a second direction different than the first direction;

the pin is configured to be inserted into first portion of the slot; and

the pin is configured to be secured in the second portion of the slot when the heater housing is coupled to the blower housing.

14 . The HVAC system of claim 7 , further comprising an upper attachment mechanism comprising:

a bracket extending from one of the blower housing or the heater housing; and

an arm extending from the other of the blower housing or the heater housing, the arm configured to be coupled to the bracket.

15 . The HVAC system of claim 14 , wherein the bracket extends from the blower housing and the arm extends from the heater housing.

16 . The HVAC system of claim 14 , wherein:

the arm defines an arm bore having an arm bore axis;

the bracket defines a bracket bore having a bracket bore axis;

the arm bore axis is substantially aligned with the bracket bore axis when the arm is disposed against the bracket; and

a fastener extends through the arm bore into the bracket bore for coupling the arm to the bracket.

17 . The HVAC system of claim 14 , further comprising:

a blower outlet defined by the blower housing; and

a heater inlet defined by the heater housing;

wherein the heater inlet is disposed on the blower outlet when the arm is disposed against the bracket.

18 . A method of assembling an HVAC system comprising:

providing an evaporator housing, a blower housing, and a heater housing;

pivotally coupling a the heater housing to the evaporator housing; and

coupling the heater housing to the blower housing in a fixed orientation relative to at least one of the blower housing or the evaporator housing.

19 . The method of claim 18 , further comprising:

inserting a pin extending from a heater housing into a slot defined by an evaporator housing;

moving the evaporator housing toward a blower housing, such that the pin moves in the slot toward the blower housing;

rotating the heater housing radially about the pin until a heater inlet defined in the heater housing is aligned with and disposed on a blower outlet defined in the blower housing.

20 . The method of claim 19 , further comprising retaining the pin in the slot with an interference fit.
