What can be a consequence of using an incorrect refrigerant in an HVAC system?

Using an incorrect refrigerant in an HVAC system can lead to mechanical failure or damage because different refrigerants have unique chemical properties, including pressure and temperature characteristics. When an HVAC system is designed, it is specifically engineered to operate with a designated refrigerant. If another refrigerant is used, it can cause improper lubrication, increased pressure, and temperature imbalances within the system, leading to premature wear or outright failure of components such as the compressor.

In some cases, incorrect refrigerants can also contribute to system leaks or corrosion, further jeopardizing the longevity and efficiency of the system. This potential for mechanical failure highlights the importance of adhering to manufacturer specifications when selecting refrigerants for HVAC systems.
