What Kind of Air Conditioning Refrigerants Are Used in Arnold, MD?

Air conditioners are a glorious invention that brings sweet relief from the hot air on scorching Arnold, Maryland, days. But have you ever considered how air conditioners work to generate cool air? Air conditioner refrigerant is key.

This essential component has undergone a fascinating transformation over the past several decades, driven by environmental concerns and a commitment to cooler summers for all. At Grove Heating & Cooling, your comfort and the well-being of our planet are our priorities. 

We’re here to explain the types of air conditioner refrigerants used in air conditioning systems throughout Arnold, MD, and how the type of refrigerant your AC unit uses can impact your future decisions about air conditioning repair and replacement.

From CFCs to a More Sustainable Future

For decades, chlorofluorocarbons (CFCs), like R-12, and hydrochlorofluorocarbons (HCFCs), like R-22 (also called Freon), were the go-to types of AC refrigerant. They were efficient at cooling, but unfortunately, they came with a hidden cost. Refrigerant leaks from systems using CFCs and HCFCs were wreaking havoc on the ozone layer—Earth’s protective shield from harmful ultraviolet radiation.

The international community took decisive action, and in 1987, the Montreal Protocol was born. This landmark agreement phased out CFC production in the 1990s due to their ozone-depleting potential.

HCFCs had a milder impact on the ozone layer compared to CFCs. However, they still had some ozone-depleting potential and contributed to the greenhouse effect. Recognizing this, the Montreal Protocol mandated the gradual phase-out of HCFCs as well.

The phase-out of R-22 happened in stages. In 2010, the Environmental Protection Agency (EPA) banned the production and import of new R-22 units. This means no new air conditioning system equipment was manufactured using R-22. Servicing an existing AC system that uses R-22 refrigerant was still permitted.

The production and import of R-22 were completely halted in 2020. Since then, only recovered, recycled, or reclaimed R-22 can be used for servicing existing equipment, such as recharging an AC unit or heat pump after fixing a refrigerant leak.

The Rise of HFCs and the Search for Greener Alternatives

Hydrofluorocarbons (HFCs), such as R-410A, became the next generation of refrigerants used in air conditioning systems and heat pumps manufactured since 2010. R-410A was chosen as a replacement for R-22 because it offered several advantages:

  • Ozone-friendly: R-410A has no ozone-depleting potential, complying with the Montreal Protocol’s regulations.
  • Higher efficiency: R-410A systems can be more efficient than their R-22 counterparts, potentially leading to lower energy bills.

However, R-410A is not without its drawbacks. It has a higher global warming potential than some newer refrigerants being developed and still contributes to the greenhouse gas effect.

Under the American Innovation and Manufacturing (AIM) Act of 2020, a phase-out of R-410A has been initiated. Starting in 2025, no new air conditioning systems will be manufactured using this type of AC refrigerant. Also, HVAC companies will no longer be able to install new air conditioners using R-410A.

Exploring Next-Gen Refrigerants

The industry is actively exploring new, more sustainable refrigerants. Here are some promising contenders:

  • R-454B: R-454B is a rising star in the world of air conditioner refrigerants. This AC refrigerant is actually a blend that combines two key components: R-32 and R-1234yf. R-454B has a significantly lower global warming potential compared to its predecessor, R-410A. This translates to a lighter environmental footprint for your home comfort.
  • R-32: R-32 is an HFC refrigerant that boasts a significantly lower global warming potential (GWP) compared to the widely used R-410A. Some studies suggest that R-32 systems can operate with slightly better efficiency than their R-410A counterparts, potentially leading to lower energy bills.

In response to this upcoming R-410A phase-out, many manufacturers have already started releasing air conditioners with newer refrigerant types.
