Impact of Very Small Leaks	Minor, lower pressure minimizes leak rates	High pressure of CO₂ makes even small leaks a problem
Impact of Charge Loss	Low leak rates and ability to hold reserve charge reduce impact on performance	Higher leak rates and limit on total charge due to pressure concerns increases impact of charge loss
Ease of Service	Flexible hoses make it easy to replace hoses and components	Stiffer hoses more difficult to work with in crowded engine compartments
Cost of Repair Parts	Similar to HFC-134a	CO₂ components are more expensive than HFC-134a
