Using AC gauges is a crucial step in diagnosing and repairing air conditioning systems. These gauges measure the pressure and temperature of the refrigerant, providing valuable information about the system’s performance. AC gauges are typically used by HVAC technicians, but they can also be helpful for homeowners who want to troubleshoot and maintain their own AC units. Understanding how to use AC gauges can empower you to make informed decisions about your AC system and ensure it is functioning efficiently.
There are two main types of AC gauges: high-pressure gauges and low-pressure gauges. High-pressure gauges measure the pressure of the refrigerant on the discharge side of the compressor, while low-pressure gauges measure the pressure on the suction side. By comparing the readings from both gauges, you can determine if the system is operating within normal parameters.
