I know that ignorance is bliss for a good reason. No one wants to know what sort of dangerous substance is around them, especially when it’s responsible for continual indoor comfort. Most of us do not ever suppose what chemical is used in our air conditioning systems, however, let it be known that it won’t be too long plus that will change. That is because the U.S. gov will soon stop making the chemical, since it’s 1 that has been proven to be damaging to our ozone layer. That chemical, R22, is seriously crucial at this point to making your air conditioning task well, however it also contains chlorine that is actually dangerous to our environment when the substance is exposed… This change will likely affect you, to be honest. All air conditioning units installed before the 2010 cutoff date are still most likely still using the old refrigerant. This chemical, available through the hired services of an Heating, Ventilation and A/C provider, should not need to be properly added to your air conditioning system, unless the plan has a leak, plus then, you’d better believe that it can only be bought by a licensed Heating, Ventilation and A/C serviceman who is actually officially trained plus certified to use this chemical. Me, being a fully trained air conditioning serviceman, happen to hold a license that allows me to purchase plus use freon regularly for my air conditioning repairs. When I get a call from a acquaintance wanting me to come right over and put freon into their air conditioning system, it is kind of annoying.
