There are generally two types of air conditioners that we use today: R22 and R410-A. Refrigerant is what makes air cold so that you can enjoy cool air inside your home, but a lot goes on to make that air cold, and you can experience problems with your HVAC unit if just one thing were to go wrong.
If you are having problems with your unit, like the refrigerant is failing, it is essential to know what refrigerant you are using so that you can determine what to do to fix or replace your air conditioner.
R22 refrigerant is also known as Freon, the older of the two refrigerants. R22 uses mineral oil for self-lubrication, allowing it to remain cold over long periods of time. It does not absorb much heat, meaning it has a good chance of compressor burnout from overheating. This refrigerant is also a hydrochlorofluorocarbon (HCFC) which is detrimental to the O-zone.
R410-A refrigerant is also known as Puron. Unlike R22, this is a hydrofluorocarbon (HFC) which does not contribute to O-zone depletion thanks to insufficient chloride found in it. This refrigerant absorbs more heat so that the unit is cooler and runs more efficiently. This means there is a less chance of the compressor overheating and burning out.
R22 vs. R410-A and the 2019 Regulation Change
R410-A is the new and improved refrigerant for air conditioning units. Compared to R22, R410-A refrigerant is more energy-efficient, it costs less to run, and is less of a hazard to the environment. R410-A is considered a great improvement over R22 and homeowners have been switching to R410-A to enjoy fewer ongoing costs and newer, more reliable technology.
In late 2019, R22 refrigerant will become discontinued, meaning it will be more costly and resources to repair such air conditioners will become more scarce.
If you suspect something is wrong with your air conditioner with R22 refrigerant, we suggest replacing your air conditioners with one that supports R410-A. Repairing your old air conditioners might be more costly than replacing it, and sooner or later, that old unit will need to be fixed again anyways. At the same time, you could get a new air conditioning unit with R410-A and expect it to run fine for a handful of years until you might need further service for it.
if you have any questions or concerns about your current air conditioning unit or the possibility of getting a brand new one.
