If an air conditioner is not cooling as well as it once was, it may need Freon. Some signs of this include the air conditioner being turned up to the highest setting, but barely producing any cold air, or cold air not coming out at all. Another sign is if large amounts of water are leaking from the air conditioner's air handler.Continue Reading
An additional sign that an air conditioner may need Freon is if the unit's pipes freeze over or if the unit's outside lines frost over inside of the condenser.
Freon is used to transfer heat from inside a building. After it absorbs the heat, it transfers the hot air outside to cool the air down. The cooler air is transported back inside the building, and the process repeats itself. The Freon inside the unit continuously circles through the system, so the air conditioner does not need regular refilling. If the air conditioner is low on Freon, it is most likely caused by a leak in the unit. An air conditioner should receive an HVAC tune-up at least once a year to help prevent leaks from occurring. The best time to schedule a tune-up is in the spring before cooling companies become booked with summer orders.Learn more about Heating & Cooling
Most vehicles need 25 to 35 pounds per square inch of Freon on the low side if the vehicle is running with the air conditioner on its coldest setting and fastest fan speed. The amount of Freon a vehicle uses is measured in pounds per square inch, or psi.Full Answer >
Most window air conditioners do require Freon in order for them to work properly. There is a type of Freon referred to as R-22 or HCFC-22, and it was most common in air conditioner window units prior to 2010.Full Answer >
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.Full Answer >
An air conditioner coil is the part that turns a liquid chemical such as Freon into a gas and absorbs heat while creating cool air. The coil functions as a heat exchanger, because it draws out heat and creates the cool air that blows out of the air conditioner.Full Answer >
