Stop adding freon every year!
Educational Page on freon leaks here Finding Freon Leaks
In all our years of doing service work we have never found a bigger reason for freon leaks than leaks at the service valves themselves.
When the original installer sweats the copper joints with a torch he or she is supposed to be wrapping the brass valves with a wet rag to keep from burning the small seals that are in these valves. This unfortunately many times, doesn't happen. Once these seals are destroyed you either have to pay to install new ones or continually be adding freon. Of course there are other places to have freon leaks but this is a PRIME place to look. See leak finder solution below.
To answer a question that gets asked over and over - NO you can NOT recharge a system yourself. It takes an E.P.A. Certification to buy or use refrigerants and it takes special equipment and knowledge to correctly charge an AC unit! There used to be "Kits" to re charge automobiles ( and still may be ) but there are NO SUCH "Kits" for re charging a residential unit.
SERVICE VALVE CAPS:
Once a Heating and Air Conditioning Contractor has properly re charged the unit with freon, you can use this kit by removing the larger and smaller hex brass nuts, use the tube of thread sealant on the threads of these brass caps and re install them, tighten securely but not too tight. This thread sealant is made to withstand the chemicals in refrigerant and should correct all but the most severe leaks.
SCHRADER CORE CAPS:
Now replace the smaller caps with the caps in the kit. The caps in the kit have a special "O" ring inside to stop leaks. Your schrader core caps may look different than the ones in the photo below. The caps we supply are brass with a special tool at the end to tighten any small leaks at the schrader cores. (Always wear safety glasses and gloves). Don't use the thread sealant on these caps however. Some heat pumps need three or more schrader caps. These caps should be changed every couple of years. Just tighten them slightly more than hand tight.

Directly below is a shot of a bottle of the special leak detection solution used to find freon leaks. (Brand may be substituted according to availability) (Assuming you have SOME freon in the system) If you are completely out of freon have an HVAC company add some to find your leak, otherwise it would be like trying to find a leak in your tire if it were TOTALLY flat! Don't assume the HVAC company will automatically check your entire system for leaks since this is a VERY time consuming process as you will see when you try it yourself! Remember, finding the leak or leaks is very time consuming, so if you find your own leaks you just saved A LOT of money on a service call. Tag the leaks in some manner and have an HVAC Company come out to fix the leaks.
The solution clings to any area it is applied to with a swap rod connected to the cover. Paint it on every joint you find, the service valves, schrader cores where the service gauges are installed, the coil tube bends (inside and outside which will require dismantling cabinets to get to the tube bends), the compressor fittings, filter-dryers, mufflers, accumulators, reversing valves or any other brass or copper tubing that holds refrigerant. Once it is applied, watch VERY closely for even minute bubbles. They are OFTEN VERY hard to see especially when there is a small leak, as in a leak that causes refrigerant to be added over a year or better period. The bigger the leak, the easier it is to find. Some leaks are large enough to hear! Once the leak or leaks are found and repaired, have an HVAC Company re charge your system correctly, then use the remainder of the kit shown below to seal any leaks in the service valves and/or schrader cores. DO NOT USE ANY STOP LEAK PRODUCT USED FOR CARS! Damage to your system will occur! When all leaks have been found, wash the leak finder off the connections.
