an HVAC technician performing a vacuum process on an air conditioning system.
The technician is using a vacuum pump connected through manifold gauge hoses to remove air, moisture, and contaminants from the refrigerant lines before charging the system.
The blue and red gauges monitor low and high pressures, ensuring proper evacuation.
The yellow hose connects the vacuum pump, which creates negative pressure to eliminate any unwanted gases.
The copper tubing inside the unit carries refrigerant, crucial for heat exchange.
Proper evacuation prevents system malfunctions, ensuring efficiency and longevity.
This step is essential before introducing new refrigerant to avoid contamination and compressor damage.
Regular maintenance like this improves cooling performance and energy efficiency.
