The most common types of refrigerants used in residential cooling systems are R-410A and R-22. R-410A is more environmentally friendly and is now the preferred choice, while R-22 is being phased out due to its harmful effects on the ozone layer.
The most common types of plumbing joints used in residential plumbing systems are soldered joints, compression joints, and push-fit joints.
The most common signs that indicate a need for a recharge of home AC refrigerant are reduced cooling efficiency, warm air blowing from the vents, ice buildup on the refrigerant lines, and strange noises coming from the AC unit.
Refrigerant is a chemical compound used in cooling systems. It is typically produced through a manufacturing process that involves extracting and purifying gases from natural sources or synthesizing them in a laboratory. The most common refrigerants are hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), which are created through chemical reactions involving fluorine, carbon, and hydrogen.
Ball valve plumbing is commonly used in residential and commercial settings for controlling the flow of water or other fluids. They are often used in applications such as shut-off valves for sinks, toilets, and water heaters, as well as in irrigation systems, heating and cooling systems, and industrial processes. Ball valves are preferred for their durability, ease of operation, and ability to provide a tight seal to prevent leaks.
The standard voltage for residential electrical systems in the United States is 120 volts for most outlets and 240 volts for larger appliances like stoves and dryers.
The most common refrigerant used in household refrigerators is R-134a.
The common wire on a thermostat provides a continuous flow of power to the thermostat, allowing it to operate properly and control the heating and cooling systems in a home.
Refrigerators use a refrigerant as a cooling material to absorb heat from the inside of the refrigerator and release it outside. Common refrigerants used in refrigerators include hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs).
Wye plumbing fittings are commonly used in residential plumbing systems to connect horizontal pipes to vertical pipes, such as in drainage systems for sinks and showers. They are also used to create branch connections in water supply lines, allowing for efficient water distribution throughout the home.

Freon is a name trademarked by DuPont for a line of CFC and HFC refrigerants which they manufacture. Other manufacturers make these same refrigerants, but cannot call them Freon, as DuPont has exclusive rights to the name. The common name depends on the exact refrigerant you had in mind, as different types of AC systems use different refrigerant.
The most common refrigerant used in refrigerators is R-134a.
