Most of us do not know exactly what chemical is used in our cooling systems, but the good or bad news is, it won’t be too long as well as that will change. That is because the U.S, government will soon stop making the chemical altogether. This is 1 that has been proven to be damaging to our ozone layer. That chemical, R22, is seriously quite crucial to making your air conditioning system toil well each day, but it contains chlorine that is genuinely dangerous to our environment when routinely exposed, and this change which is really a vital section of the laborings of an cooling system, will most likely affect you. air conditioning system units installed well before the 2010 cutoff date most likely still use the old refrigerant method. This chemical, available through the services of a professional Heating as well as Air Conditioning provider, should not actually need to be added to your cooling system, unless the proposal has a leak. At that point, it can only be purchased by a licensed Heating as well as Air Conditioning serviceman who is fully and properly trained as well as certified to use this chemical, and as a band new fully trained air conditioning system serviceman, I currently hold a license that allows myself and others to purchase as well as install freon for our a/c repairs. I guess I have all the power in this new freon-free world. Believe me, that freon is genuinely extravagant as well as it will only continue to increase in price over time.
