Issue: AC running but not cooling — ice on outdoor copper lines
Classic refrigerant undercharge: the indoor fan is running normally but the system cannot transfer heat because refrigerant is depleted. The icing on copper lines confirms this. Likely cause is a slow leak at a fitting or coil joint — though a failed metering device or severely restricted filter are possible secondary causes requiring professional confirmation.
Severity
Typical cost
$800–$2,800
Key insight
Running the system with low refrigerant causes the compressor to work without lubrication — burnout typically occurs within days to weeks, converting an $800–$1,500 repair into a $3,500–$6,000+ compressor replacement. Turn off the system until diagnosed.
