If you own an older A/C unit, odds are its using R-22 refrigerant to keep you cool, Hobaica Services wants you to be informed about the new refrigerant standards.
The EPA has mandated that the old R-22 refrigerant will be completely phased out. No production or importation of R-22 will be permitted beginning in the year 2020. Manufacturers of air conditioning equipment were required to phase out the use of R-22 in new equipment as of January 1, 2010.
R-22 has been the refrigerant of choice for residential heat pump and air-conditioning systems for more than four decades. The down side is that R-22 is considered a greenhouse gas, meaning that when released into the atmosphere, it contributes to the depletion of the ozone layer.
If you’re thinking about purchasing a new A/C unit, you’ll be switching to the new refrigerant. It’s called R410-A, and it’s offered under different trade names by different refrigerant manufacturers.
The R-410A systems employ thicker walled tubing, newly developed compressors/components, and higher grade oil. All require diverse installation and service procedures.
What does the switchover mean for our customers? Well, prices for the old R-22 will gradually go up but shouldn’t be outrageous for a long time. For example; if you installed a new R-22 air conditioning system in the year 2004, you will be able to get refrigerant for your system at least until the year 2020.
If you opt to retrofit your existing A/C system for the new refrigerant, you need to be aware that when a system is changed over to R-410A we will need to change the condenser, the evaporator coil and, the refrigerant copper line set, or at least have them properly flushed.
If you’re buying a new R410-A system, you may actually get a side benefit. Some products have experienced up to one full point higher SEER rating with the use of R-410A.
Ask Hobaica about the new refrigerant standards if you’re in the market to repair or replace your A/C unit. We can advise you about choosing a new unit, or change you over if you’d like to “go green” with your air conditioning.
