Leaky room - non-inverter

Old York, daikin, acson - all same company and factory.
Panasonic is second best selling.
Other brand - have spare part issue.

R22's gas had stopped production
R410a's gas is stopping in 2024
R32 is the future

R22 pipe size is .51mm
R410a & R32 is .61mm (recommend .8mm)

R22 > r410a / r32 : should change piping due to different size. No change = pipe bocor in the future.

R410a > r32: Manufacturer advise replacing, contractor advise re-using. Technology wise, r410a is mixture of 50% R32 and 50% r125. I'm on the reuse camp as long as pipe is properly flushed (many contractor fuck up on this, as evident on r22>r410a upgrade) and is <10 years old.
