What is Refrigerant?

Refrigerant is the working fluid in ACs that absorbs heat from your room and releases it outdoors. It continuously cycles between liquid and gas states.

Common Refrigerant Types

R22 (Chlorofluorocarbon)

  • Older standard used until 2010s
  • Damages ozone layer (being phased out)
  • Still used in some older ACs
  • No longer manufactured in many countries

R410A (Hydrofluorocarbon)

  • Modern replacement for R22
  • Doesn't damage ozone layer
  • More energy-efficient than R22
  • Currently most common (except in new regulations)
  • Lower GWP than R22

R32 (Hydrofluorolefin)

  • Newest and most eco-friendly option
  • 30% more efficient than R410A
  • Lower Global Warming Potential (GWP)
  • Becoming standard in new ACs
  • Lower refrigerant charge needed (25-30% less)

Why Refrigerant Matters

  • Affects cooling efficiency
  • Environmental impact (global warming)
  • Availability and cost
  • Future proofing your AC

For Your AC

If buying new: Choose R32 ACs for best efficiency and future compliance. If your old AC uses R22, service it carefully; refills are expensive and limited.

What If Your AC Leaks?

Don't ignore refrigerant leaks. A leaking AC loses efficiency and harms the environment. Call a technician for immediate service.

Conclusion

R32 is the future of air conditioning. When replacing your AC, prioritize models with R32 refrigerant for long-term efficiency and environmental responsibility.

Frequently Asked Questions

Can I switch from R22 to R410A or R32?

No, switching refrigerants requires system changes. Stick with the original refrigerant type for your AC.

Is R32 more expensive to maintain?

R32 is slightly more expensive for refills, but modern ACs leak less due to better sealing. Overall costs are comparable.

Why is R22 being phased out?

R22 damages the ozone layer. Phasing out older refrigerants helps protect Earth's ozone layer from further damage.
