What is the role of pressure gauges in HVAC systems?

Pressure gauges play a crucial role in HVAC systems by monitoring refrigerant pressure levels, which is essential for safe and efficient operation. HVAC systems require specific pressure ranges to function optimally. Too high or too low pressure can result in inefficient cooling or heating, potential equipment damage, and safety hazards. By continuously monitoring these pressure levels, technicians can diagnose system performance, identify potential issues before they become serious problems, and make necessary adjustments to maintain system health.

The other options do not accurately reflect the primary function of pressure gauges in an HVAC context. While temperature measurement, airflow assessment, and energy consumption calculations are important components of HVAC management, they are typically performed by other tools or methods. Pressure gauges specifically focus on refrigerant pressures, making them indispensable for ensuring the safe and efficient operation of the system.
