HOW A 1987 TREATY CHANGED AIR CONDITIONING IN 2010
Ever heard of the Montreal Protocol? Like many things that happen among and between nations, even if you haven’t heard of it, we’re talking about an event that could affect your life – or, in this case, your home comfort.
Offered up in 1987 for nations to sign and adopt, the Montreal Protocol was an international treaty that focused on a concern for how chemicals and other things in the atmosphere were depleting the ozone layer that was protecting life as we know it on earth. The treaty was amended in 1992 to set a timetable for phasing out chemicals known as HCFCs – which includes in this list a refrigerant that has been used in air conditioning systems since the early ‘70s.
Now, fast forward to today and what this means in practical terms for you: Air conditioners manufactured after 2010 can no longer use the refrigerant R-22 (also known by the brand name Freon) as the coolant of choice. While this refrigerant can still be produced and used to service existing equipment for the time being, in 2020, the production and import of R-22 will end, and it will only be available through recycled and reclaimed processes.
That means simply this: any air conditioning that uses R-22 is looking at a time limit. As you face repairs with any pre-2010 system, we’ll be glad to talk with you about the best ways to extend the life of the equipment (hint: regular maintenance!), and when the time is right for replacement, we’ll give you our best guidance there too.
