Abstract: An improved support structure for a valve stem positioned within a valve passageway of an HVAC line set quick connector is disclosed herein. The support structure may include a ring-shaped portion, a plurality of angled legs extending peripherally away and below the ring-shaped portion, and a plurality of terminal portions. The ring-shaped portion may be configured to surround the valve stem. Each of the plurality of terminal portions may be coupled to one of the plurality of legs and may further include an arcuate surface configured to engage the valve passageway of the HVAC line set quick connect. The improved support structure is configured to increase a cross-sectional opening area through the support structure such that coolant flowing through the HVAC line set quick connector is not substantially restricted.

Abstract: Apparatuses, systems, and methods for de-energizing an indoor HVAC unit are provided herein. The system comprises an outdoor HVAC unit, an indoor HVAC unit, signal cables coupled between the outdoor HVAC unit and the indoor HVAC unit, and an air-gap switch connected to the indoor HVAC unit. The signal cables are configured to electrically power the indoor HVAC unit from the outdoor HVAC unit. The air-gap switch is connected to the indoor HVAC unit and is configured to selectively sever a connection between the signal cables and the indoor HVAC unit. The air-gap switch provides an electrical safety measure for servicing and maintaining the indoor HVAC unit.

Abstract: Apparatuses, systems, and methods for providing non-expert installation of HVAC systems are provided. The HVAC system includes an indoor unit, an outdoor unit, a first pre-charged refrigerant line-set, a second pre-charged refrigerant line-set, and a line-set coupler, each containing pre-pressurized refrigerant securely positioned therein prior to engagement between two or more of the aforementioned elements. The first pre-charged refrigerant line-set is couplable between an indoor unit refrigerant port of the indoor unit and a first coupler end of the line-set coupler. The second pre-charged refrigerant line-set is couplable between an outdoor unit refrigerant pot of the outdoor unit and a second coupler end of the line-set coupler.

Abstract: A ductless HVAC system solution equipped with quick-connecting connectors and a line-set pre-charged with refrigerant and method of installation thereof. The system is simplified such that an amateur may conduct the installation without professional assistance. Pre-charged refrigerant line-sets, which are designed to contain the recommended pressure of requisite refrigerant are employed. A quick-release connection system housed within quick-connect connectors ensures refrigerant does not leak from the pre-charged refrigerant piping during installation, and ensures manual refrigerant charging is not needed. The quick-connect connectors feature a double-sealing system with a unique automatic safety valve which releases the refrigerant only when the indoor and outdoor components are connected and sealed, avoiding any potential leakage.

Abstract: A ductless HVAC system solution is described. The system is configured for easy installation by an amateur, and therefore does not require a license, expensive tools, or much time to install. The system is equipped with pre-charged refrigerant piping, which are designed to contain the recommended pressure of requisite refrigerant. A quick-release valve system ensures refrigerant does not leak from the pre-charged refrigerant piping during installation by an amateur. The system may be controlled manually or remotely via WiFi. Thus, the system features a double-sealing system with a unique automatic safety valve which releases the refrigerant only when the indoor and outdoor components are connected and sealed, thus avoiding any potential leakage.
