Freon or R22 is the most common refrigerant used in a majority of HVAC and refrigeration systems around the world. That is due to the HVAC compatibility and energy efficiency of the substance. But it was discovered that R22 causes harm to the ozone layer of the planet. Hence, the world leaders who convened to Montreal in 1987 decided to phase out the substance in stages. This agreement is popularly known as the “Montreal Protocol.” The first stage of the phase-out began as far back as 2010 where the production and importation of Freon to the United States were restricted.
A limited quantity was allowed to be produced to service and repair the existing HVAC systems. The second stage of phase-out was implemented in 2015 where R22 was banned in new HVAC units. The final phase-out is planned to be implemented from 1st January 2020 where the substance will be completely banned. You won’t find R22 even for repairs and maintenance after the 1st of January 2020. Hence, you won’t be able to replace Freon in your central AC system after this date. This article provides information on what you should know about replacing Freon in your central AC system.
R22 or Freon will no longer be available on the market after January 2020. If you have an older unit that operates on Freon, you won’t face any issues until you experience a Freon leakage from the system. In case you experience such a leakage, you won’t find R22 in the market to replace the unit. That is why you should be cautious with your existing HVAC unit if it operates on R22. You should be adhering to the proper preventive maintenance strategies to prolong the lifespan of the unit. That way you will be able to use the existing unit for some time without any problem. In case, you experience a Freon leak right now, you can buy Freon on the market to replace the existing unit. But you will have to pay a significant amount of money for a pound of Freon today. In fact, a wholesale pound of Freon will cost around $35 to $40 on the market today. With the limited quantity available on the market, suppliers who have stocked up R22 are taking advantage of the supply and demand situation to increase the price of the refrigerant. Hence, you may have to incur a fortune to replace Freon in your central AC system if it experiences a leakage. That is why it is important to do the preventive maintenance work properly so that the system doesn’t experience a Freon leakage. That is the best way to prolong the lifespan of your central AC system and save money in the process.
R410A is an alternative refrigerant that was introduced to the market to replace Freon after the latter is completely banned in 2020. In fact, R410A is energy-efficient and eco-friendly compared to Freon. It doesn’t cause any harm to the ozone layer of the planet. Hence, you have two options to consider in case your HVAC system experiences a Freon leak either now or after the 1st of January 2020. The first option is to replace your old HVAC system with a new system that uses an eco-friendly gas such as R410A. But you should have the necessary funds to switch the old system for an energy-efficient new system. If your budget allows, it is the best option available to your in the long-term. Even though you may have to incur a significant up-front cost to switch the old system to a new energy-efficient system, you will save money on your energy bills in the long run. That way you will save money over time though you spend a significant up-front cost.
If you don’t have the budget for the first option, there is another option for you. That is to replace the R22 in the current system with R410A. This option is much cheaper than replacing the entire HVAC unit. But you cannot take out the R22 and just replace it with R410A. This conversion isn’t viable due to the higher pressure of R410A. Hence, you have to replace the coil and compression of the current system with coils and compressors that are compatible with R410A. Once you have replaced these parts, you can replace R22 with R410A in your current system. This is a more viable option for homeowners who don’t have the up-front cost to replace the entire system with a new one.
In case your central AC system experiences a Freon leak right now, and you have the money to invest in R22 – which is quite costly due to the supply and demand situation, here is how to replace Freon in your central AC system. You can find out here best place to buy tdx 20.
How To Add R22 Or Freon To Your Central AC System?
The first step is to gather your supplies such as the refrigerant Freon, protective mask, gloves, goggles, a pressure and temperature gauge, and a Freon repair kit. The next step is to power off the unit and the electricity that goes to that unit or the area of the house. It is important that you take the necessary safety measure before replacing the refrigerant. Although Freon isn’t toxic, you should be wearing all the protective gear before you begin the operation.
Now attach a temperature gauge to the valves and wait for 5 minutes before reading the gauges. You can find the appropriate reading in the instruction manual that comes with the AC unit. After some inspection, you can find the source of the refrigerant leak in your system. Once you trace the leak, attach the repair kit to the compressor and follow the instructions in it. In order to recharge the central AC system, you need to reconnect the gauges and connect the R22 to the gauges. In fact, you need the gauges to get a proper reading in the process. Once everything is connected, you should release the valve on the R22 container and let it circulate through the system. Add small amount at a time to get a correct reading. In case you find the process too complicated, you can always call a professional HVAC contractor in the area to handle the process.
