If you’re looking to replace your existing air conditioner, you have a few options: If your current system is still working, you may be able to get away with just replacing parts and components. For example, if you’re having trouble with the compressor or condenser, you might be able to replace those components and keep your existing system. This is a good option if you’re on a budget or want to avoid having to buy an entirely new system. If the whole system needs to be replaced, you should consider switching over to an entirely different type of refrigerant. You might want to consider converting your old R-22 system over to one that uses R-410A or R-134A as an alternative.
