AC Gas Depleted? 4 Easy Tests to Spot Leaks & Avoid Unnecessary Refills

• Check AC cooling performance for 10-15 minutes before technician arrives; proper cooling means low chance of gas depletion.
• Look for ice formation on indoor unit coils, but also check for dirty air filters or low airflow as potential causes.
• Inspect outer unit pipe joints for oily stains or wetness, which indicate a gas and oil leak.
• Demand a bubble test from the technician using soap solution at pipe joints to visually confirm any gas leaks.
• AC gas doesn't deplete annually; reduced cooling can be due to dirty filters, faulty fans, or low voltage, not just leaks.
