A 3-ton air conditioning unit can hold 6 to 12 pounds of Freon, depending on the unit. The exact amount of Freon needed is determined by a variety of factors, such as the type of unit and where it is installed.Know More
The amount of Freon or other refrigerant necessary to fill any size air conditioning unit depends on factors such as the size of the evaporator coil and whether the air conditioner is an all-in-one, self-contained exterior unit or a split system unit in which the condenser and compressor are outside and the air handler and coil are inside. The length of the lineset, the copper pipes which connect the outside condensing unit to the indoor evaporator coil on a split system unit, also affects the amount of Freon necessary to fill the unit, as does the diameter of the lineset tubing.
The seasonal energy efficiency ratio of the unit also impacts the amount of Freon an air conditioner requires; the higher the SEER rating, the larger the evaporating coil. The larger coil surface makes the air conditioner more efficient while increasing the amount of Freon needed to fill the unit. Freon, also known as R-22, is regulated by the Environmental Protection Agency, and only an EPA-certified technician can buy and handle it.Learn more about Heating & Cooling
The evaporator coil is the primary contact point for warm air in a central air conditioning system. The purpose of the evaporator coil is to remove the heat and humidity from the air that is passing over it.Full Answer >
As of 2014, the cost of installing an air conditioning unit in a 1,600-square-foot house falls between $3,000 and $5,000. If the duct work of the central air conditioning unit needs to be installed as well, then this price doubles.Full Answer >
Using whole-house attic fans helps to reduce the costs of air conditioning when outside temperatures are below the normal thermostat setting inside the house. The most efficient use involves shutting off the fan and closing windows before daytime heating increases outside temperatures.Full Answer >
A 12 foot by 12 foot room will require an air conditioning unit with a cooling capacity of 5,000 British thermal units, or BTUs, according to the Energy Star website. To arrive at this figure, the square footage of a room must first be determined and then the area should be used as reference to determine the ideal BTUs needed.Full Answer >
