🔧 Tool Tip Thursday ❄️
Did you know?
One of the tools technicians use during A/C diagnosis is a sight glass. By inspecting the refrigerant and oil through the sight glass, we can check for signs of contamination, moisture, debris, or other issues that may affect system performance and reliability.
Catching contamination early can help prevent damage to expensive A/C components such as the compressor, condenser, and expansion valve.
A thorough diagnosis goes beyond checking pressures—it helps ensure the entire system is operating as intended.
