When your window AC unit stops blowing cold air but is functioning properly in every other regard, it is likely low on coolant. This means that the unit will have to be recharged with a fresh infusion of coolant, likely Freon. That isn’t necessarily a given though. Be sure to research what specific coolant your window air conditioner uses. If it does turn out to be Freon, you can buy a Freon kit, which will include all the tools and instructions necessary to get you through the AC recharge process. Note that Freon is toxic to humans and any handling and safety instructions that come with your kit should be taken very seriously. DISCLAIMER: Depending on your local laws, the use of refrigerants like Freon and even tinkering with the inner workings of an air conditioner unit are illegal unless you are specifically licensed to do so. Look into your local regulations and make sure that you are not breaking any laws by attempting a project like this. Unlike central air conditioner units, window air conditioners only draw power from the wall socket they are plugged into.

Simply removing the plug will ensure that you can open up the machinery and inspect things safely. Some AC units can be opened by simply sliding the front ends out of place, while others will require the aid of a screwdriver. Consult the owner’s manual for your specific device to determine the proper method. Having successfully opened up your window conditioner, you will need to carefully check for any signs of leakage. If you locate any leaks, fix them or call in a professional to do so before using the device again. If no leakage is present, consult the device's owner's manual to determine the proper amount of refrigerant you’ll need to add. Using both the unit’s manual and the tools included in your Freon kit, locate the compressor part of the window AC and the two lines coming off it. Next, take the service valve from your kit and attach it to the compressor line. The compressor should still have one free, unattached line extending from it. Take this remaining compressor line and attach it to the tap valve, which will also be included in the Freon kit.

Attach both of the valves that you’ve just installed, the service and tap valves respectively, to your container of Freon. The kit should contain a detailed diagram showing how to properly position the coolant tank between the two valves.frigidaire window ac unit manual When you’re assured that everything is connected tightly and properly with no potential for leaks, plug in your window AC unit and power it on at its highest setting. car ac repair naples flWith the Freon tank now directly linked to the unit’s inner working via the service valve and tap, the normal flow of air that occurs while the unit is operational will push or “charge” Freon into the unit.auto air conditioning repair wichita falls tx

When the unit is finished taking in the amount of Freon mentioned in your user manual, power down the unit, unplug it, remove the valves from the compressor, and place the unit back in its housing. To reiterate, in many parts of the country this work is legally restricted to people who are licensed experts. Assuming you can even legally attempt it, if at any point in the process you become confused or unexpected problems arise, stop what you’re doing immediately and call a professional. When this process is handled incorrectly is can be damaging to the window air conditioning unit and dangerous to the user."The difference between a successful person and others is not the lack of strength, not the lack of knowledge, but rather the lack in will."Vince Lombardi"Success is the sum of small effort, repeated day in and day out."Robert CollierHow Can I Tell if I Have a Freon Leak? is a trade name for a class of chemicals (known as Chlorofluorocarbons or CFC's) used as a refrigerant in air conditioning systems.

Freon is a gas at room temperature and a liquid when cooled or compressed. Freon gas is colorless, non-flammable and relatively odorless. Some Freons have an ether-like odor. gas is added to the compressor of the AC unit. This compressor is located outdoors on AC split-systems and inside wall-mounted residential units. Freon is added to a closed looped system and continuously recycled. Freon gas leaks can ocurr at the outdoor compressor or indoors as the Freonliquid is pumped into the AC unit. The Air Conditioning Contractors of America (ACCA) recommends the coolant level in your HVAC system be checked every year. A system that is only 10% low in coolant will not operate efficiently and can cost over 20% more on your monthly utility bills. Continued operation of your HVAC units with low coolant can damage your compressor. Freon is 4 times heavier than air and sinks to the ground/floor initially when a leak occurs. Freon will rapidly disperse due to its high volatility. Federal law prohibits adding Freon to a leaking system.

Repairs to fix the leak must be completed prior to adding Freon as Freon has been shown to damage the Earth's protective Ozone layer. is dependent upon the amount of Freon in the system and the space/size of the area where the leak occurs. Representative quantities of Freon by type used include: Note: Freon is also used extensively in the food service industry during storage, processing and transport including supermarkets. Reportedly, Freon does not have serious long-term health effects. It is not a carcinogen, mutagen or cause damage to the liver. It is primarily a simple asphyxiant which displaces oxygen causing dizziness and suffocation at very high concentrations. It has limited irritation effects. Persons with a history of heart problems are most at risk since it has been shown to cause irregular heart beats and palpitations in high concentrations. Air conditioners work by removing heat from warm air in your buildings/homes and replacing it with cool air until the thermostat reaches the desired temperature.

Freon provides cooling by: HVAC units also help clean the air inside your facility by filtering the air of dust, pollen, mold spores and other allergens. Air conditioners also function as dehumidifiers as they take excess water vapor from the air and use it to help cool the unit. How Can I Tell if I have a Freon Leak? Don't rely on a detectable odor. Look for frost-like buildup on the copper lines around the HVAC unit. Check to see if the HVAC unit is blowing warm air. If you discover you have a Freon leak, evacuate the building and contact your HVAC technician for immediate repairs. Windows and doors can be opened and fans used to bring fresh air into the building. If you feel any unusual health effects, seek medical care.
