An air conditioner's condenser is one of the main parts of an air conditioner, and problems with the condenser can lead to the permanent breakdown of the system. If, for any reason, an air conditioner owner cannot find a trustworthy HVAC company to replace the malfunctioning condenser, they can replace the outer part themselves.
However, the owners may not be able to effectively replace the condenser, leading to the inefficient working of the air conditioner. Moreover, it can hamper the system's warranty conditions, which means the owner would have to pay for all air conditioner expenses. So, the best situation is to contact a professional to replace the condenser.
