Freon \u00ae is a trade name give to refrigerants by DuPont. \u00a0These are most commonly used in refrigeration and air conditioning units.\u00a0They have also been used as propellants in\u00a0aerosol cans as well as many other uses.\u00a0\u00a0Refrigerants were developed at first\u00a0by General Motors\u00a0wanting to replace more dangerous chemicals such as ammonia. \u00a0There are many different types and makers of refrigerants.\u00a0\u00a0They are\u00a0most still commonly called Freon by home owners, after DuPonts original trade name. \u00a0Due to the Montreal Protocol Act most\u00a0refrigerants are now regulated or banned completely from manufacturing. \u00a0Of those, r-12 (used mainly in cars, refrigerators). \u00a0R-11 used for chillers, aerosol cans, and cleaning).\u00a0R-502 (used for freezers, and cooling boxes) are no longer allowed to be manufactured in most countries.<\/p>\n
R-22 which it mainly use in\u00a0air conditioning\u00a0 has been limited in its production and is set to be phased out with-in the\u00a0a few years. \u00a0Although you can still buy most of these refrigerants some are no longer “virgin” and are getting more expensive by the year.<\/p>\n
Most ac units still use r-22\u00a0and it is still available to purchase.\u00a0It can still be manufactured in the US, although the cost has more than tripled in the last 3 years.\u00a0\u00a0R-22 is odorless, colorless and\u00a0non toxic as it sits. \u00a0It is made up of methane, chlorine and Florine gases. \u00a0The main health risk comes from breathing in to much Freon and displacing the oxygen in your lungs.<\/p>\n
Due to the growing cost of Freon \u00ae\u00a0r-22 we suggest that if\u00a0your system\u00a0becomes low, you find where the leak is.\u00a0Or why the Freon is low before just adding more.\u00a0\u00a0In the long run it is much cheaper to repair the issue than\u00a0to continue to add\u00a0refrigerant\u00a0over and over. \u00a0For this and any other a\/c or heating repair needs, give us a call at 208 898-9888\u00a0and continue reading our blogs for more useful information.<\/p>\n
