Simply putting more refrigerant into a leaking system will not fix the problem. How To Put Freon in AC UnitĪdding Freon to your system may help some of the immediate issues, but low Freon levels point to a larger problem somewhere in your air conditioning system. If one of our technicians discovers that your system has a low refrigerant level, we’ll find the leak, repair your air conditioner, and recharge the system by adding more refrigerant. An HVAC technician at Lex Air can perform regular maintenance on your system, and this service includes making sure your system has enough refrigerant to cool your home properly. How Often Does Home AC Need to be Recharged?Īs stated earlier, home AC units don’t really have a set schedule for when they should be recharged. If you notice any of these signs with your air conditioner, contact the experienced technicians at Lex Air Conditioning and Heating. Short cycling (system turns on and off repeatedly).Common signs of a refrigerant leak include: Most homeowners are aware of what signs and symptoms to look out for when they need air conditioning maintenance. A gas leak, however, is not as noticeable. Depending on where the leak is, there could be a puddle around your outdoor AC unit. Freon is both a gas and a liquid at different points in your AC unit. But freon leaks aren’t as easy to find as a leaky water pipe. If your system actually needs more Freon every year, you have a leak somewhere. If you pay technicians from other companies to recharge your AC unit every summer, you’re likely being exploited. How To Know If Your HVAC Unit Needs Refrigerant Once the leak is fixed, your AC unit shouldn’t have any more issues with refrigerant. Once there is a leak in the system, the leak should be repaired by a licensed HVAC technician and more Freon should be added. Without some type of leak or malfunction, Freon cannot escape the system. So why do so many people assume they should be replacing their Freon or refilling refrigerants? Unlike cars and vehicles, air conditioning units are closed systems. Freon is not depleted during the life of your cooling system. In an ideal world, your air conditioner would never need more Freon. How Often Do Air Conditioners Need Freon? As air from your home runs over the coils inside your unit, the air is cooled and sent back into your home. Freon is a gas at room temperature but becomes a liquid when cooled or compressed. The hot air is pumped outside and the process repeats itself. Your air conditioner works by pulling air from inside your home and cooling it before circulating it back through your home. Without some type of refrigerant, your air conditioner would just be blowing warm air. Why Do Air Conditioners Need Freon?Īir conditioning systems need a refrigerant to pump cool air throughout your home. The cooling effect comes from a refrigerant used in the coils and inner workings of the AC unit. Without a refrigerant, your air conditioner would just be a very big and expensive fan. Soon, R-410A will be phased out and replaced with R-32. R-410A replaced R-22 as a more efficient (and environmentally friendly) way to transfer heat. As of 2020, it is illegal to manufacture or import Freon R-22 in the United States. The Environmental Protection Agency ( EPA) has been working since 1993 and began phasing out Freon-22 in 2010. This type of Freon contributes to the breakdown of the ozone layer. The Freon that most systems used to run on (R-22 or Freon-22) is now banned in the United States. Freon has become interchangeable with the word ‘refrigerant’ the same way Velcro is used to describe any hook and loop closure. Freon is simply the brand name for an air conditioning refrigerant. AC units use Freon to blow cool air throughout your home.
