1. An HVAC system, comprising: a reversing valve comprising a first port, a second port, a third port and a fourth port, wherein the reversing valve may be placed into a first position in which the first port is operably coupled to the second port for the flow of refrigerant therebetween, and a second position in which the second port is operably coupled to the third port for the flow of refrigerant therebetween;a first HVAC component operably coupled to the first port;a second HVAC component operably coupled to the second port;a third HVAC component operably coupled to the third port; anda static volume operably coupled to the fourth port. 2. The HVAC system of claim 1 further comprising: a first check valve operably coupled between the first HVAC component and the first port;wherein the first check valve prevents the flow of refrigerant from the first HVAC component into the first port. 3. The HVAC system of claim 2, further comprising: a second check valve operably coupled between the third HVAC component and the third port;wherein the third check valve prevents the flow of refrigerant from the third HVAC component into the third port. 4. The HVAC system of claim 1, further comprising a controller in electrical communication with the reversing valve, the first HVAC component, the second HVAC component, and the third HVAC component. 5. The HVAC system of claim 1 wherein, the first position operably couples the third HVAC component to the fourth port. 6. The HVAC system of claim 1 wherein, the second position operably couples the first HVAC component to the fourth port. 7. The HVAC system of claim 1 wherein, the first HVAC component is an appliance for conditioning air. 8. The HVAC system of claim 1 wherein, the first HVAC component is an appliance for heating water. 9. The HVAC system of claim 1 wherein, the second HVAC component is a heat pump. 10. The HVAC system of claim 1 wherein, the third HVAC component is an appliance for conditioning air. 11. The HVAC system of claim 1 wherein, the third HVAC component is an appliance for heating water. 12. A method of controlling an HVAC system with a reversing valve including a first port, a second port, a third port, and a fourth, the method, comprising the steps of: (a) commanding the reversing valve to move to a first position;(b) operating a first HVAC component and a second HVAC component to circulate a refrigerant therebetween;(c) commanding the reversing valve to move from the first position to a second position;(d) operating the second HVAC component and a third HVAC component to circulate a refrigerant therebetween and(e) operably coupling a fourth port to a static volume. 13. The method of claim 12, wherein the first HVAC component is operably coupled to the second port. 14. The method of claim 12 wherein, the second HVAC component is operably coupled to the first port. 15. The method of claim 12 wherein, the third HVAC component is operably coupled to the third port. 16. The method of claim 12 wherein, the first position operably couples the first port to the second port and the third port to the fourth port. 17. The method of claim 12, wherein the second position operably couples the first port to the third port and the second port to the fourth port. 18. The method of claim 12 further comprising: (f) equalizing a pressure of the static volume with a pressure of the third HVAC component when the reversing valve is in the first position and the pressure of the third HVAC component is lower than the pressure of the static volume; and(g) equalizing the pressure of the static volume with a pressure of the first HVAC component when the reversing valve is in the second position and the pressure of the first HVAC component is lower than the pressure of the static volume.
