A pre-charged heating/cooling system is shown for installation by unlicensed personnel. An outside unit includes an outside coil, outside fan, compressor and a reversing valve. An inside unit has an inside coil, inside fan for drawing air through the inside coil and discharging the conditioned air into the enclosed space, and a power cord connection. A cable sheath contains all connections from the inside unit to the outside unit with electrical connections being secured in position on the outside unit by a cover and a bracket. An expandable window sill holds and seals the cable sheath in a window opening.

1. A ductless, pre-charged HVAC system for installation by unlicensed personnel, said HVAC system to condition air within an enclosed space having walls there around, said HVAC system comprising: a pre-charged outdoor unit including an outdoor coil, an outdoor fan for drawing outside air through said outdoor coil, a compressor and a reversing valve;a pre-charged indoor unit including an indoor coil, an indoor fan for drawing inside air through said indoor unit and a filter for filtering the inside air;a cable sheath for connecting said indoor unit to said outdoor unit through an opening in said wall, said cable sheath including dual refrigerant lines for supplying refrigerant between said indoor coil and said outdoor coil, an electrical cable for supplying power to said outdoor unit from said indoor unit and a drain line from said indoor coil to outside said enclosed space;power cord for connecting said indoor unit to an electrical outlet;quick refrigerant connector between said dual refrigerant lines and said outdoor unit to allow refrigerant to flow back and forth between said outside unit and said inside unit;connector cover on said outdoor unit receiving an electrical connector end of said electrical cable therein and a bracket holding said electrical connector end of said electrical cable inside said connector cover, said electrical connector end connecting to an outdoor power plug of said outdoor unit, said electrical connector end and said outdoor power plug being secured under said connector cover, said connector cover has a lid to allow access to said electrical connector end and said outdoor power plug without removing said connector cover. 2. The ductless, pre-charged HVAC system as recited in claim 1 wherein said bracket clamps said electrical connector end of electric cable in place even when said electrical cable and said outdoor power plug are disconnected to keep said electrical connector end from dropping down and causing a short. 3. The ductless, pre-charged HVAC system as recited in claim 2 wherein said lid to bracket must be opened before said connector cover can be moved thereby allowing said electrical connector end of said electrical cable to be disconnected first. 4. The ductless, pre-charged HVAC system as recited in claim 3 wherein said bracket has a mouse hole therein to hold said electrical cable in place. 5. The ductless, pre-charged HVAC system as recited in claim 1 wherein said drain line is separated from said cable sheath outside said enclosed space to dispose of condensate. 6. The ductless, pre-charged HVAC system as recited in claim 1 wherein said system includes a telescoping sill with a notch therein for holding said cable sheath therein under a window in said wall, said telescoping sill being locked in position with a pin. 7. The ductless, pre-charged HVAC system as recited in claim 6 wherein said telescoping sill has a flexible material there around to seal said window, including around said cable sheath. 8. The ductless, pre-charged HVAC system as recited in claim 1 wherein said cable sheath has a large chamber for said dual refrigerant lines and said electrical cable and a small chamber for said drain line. 9. The ductless pre-charged HVAC system as recited in claim 8 wherein said cable sheath has scoring lengthwise thereof to allow said drain line to be separated outside said enclosed space from the remainder of said cable sheath to dispose of condensate. 10. A method of installation of a ductless, pre-charged HVAC system by unlicensed personnel to condition air of an enclosed space having walls there around and at least one vertically moveable window in said walls, said method including the following steps: selecting a location for an inside unit on said wall, said inside unit including an inside coil, inside fan for drawing inside air through said inside coil before discharging into said enclosed space and filters for filtering said inside air;sealing an expandable window sill adjacent said window, said telescoping sill having a sealable notch therein large enough to receive there through from said indoor unit a cable sheath with an electrical cable, dual refrigerant lines and a drainage line therein;mounting said indoor unit on one of said walls;extending said cable sheath with electrical cable, dual refrigerant lines and said drainage line through said sealable notch;securing said outdoor unit to a lightweight shipping pad;placing said outdoor unit and said lightweight shipping pad outside said enclosed space but near said window;first connecting outside dual ends of said dual refrigerant lines to a dual refrigerant connector mounted on said outdoor unit with a quick refrigerant connector;second connecting an outside female end of said electrical cable to a male electrical connector mounted on said outdoor unit;clamping with a bracket said electrical cable near said outside female end to prevent said female end from reaching the ground when unplugged;covering with a cover said outside dual ends of said refrigerant lines and said outside female end of said electrical cable when connected; andplugging said inside unit into an electrical outlet and turning the HVAC system ON. 11. The method of installation of a ductless, pre-charged HVAC by unlicensed personnel as recited in claim 10 wherein said covering step includes attaching said cover to said bracket and thereafter closing a lid that allows access to electrical connections to said outside unit. 12. The method of installation of a ductless, pre-charged HVAC by unlicensed personnel as recited in claim 11 wherein said bracket holds said electrical cable near said outside female end in position even when electrically disconnected. 13. The method of installation of a ductless, pre-charged HVAC by unlicensed personnel as recited in claim 10 wherein said dual refrigerant lines and said electrical cable are retained inside said cable sheath which terminates adjacent said outside unit. 14. The method of installation of ductless, pre-charged HVAC by unlicensed personnel as recited in claim 13 wherein said drainage line is removable on each end thereof by scoring along said cable sheath thereby allowing condensate from said drainage line to drop to the ground. 15. The method of installation of ductless, pre-charged HVAC by unlicensed personnel as recited in claim 14 wherein said cable sheath is inserted in said sealable notch, a flexible material sealing said sealable notch and a sheath clip cover covering said sealable notch.
