5/5 Heat pump diagnostic and duct review
"Copperline did not rush to sell us a new system. Daniel measured static pressure, checked the return path and explained why our upstairs rooms were hot even after the old AC had been serviced twice."
5/5 Coastal AC repair and maintenance
"Our condenser near the beach kept throwing faults. Copperline documented the electrical readings, cleaned the coil, showed us where corrosion was starting and gave us a realistic repair-versus-replacement plan."
5/5 AC airflow and heat load troubleshooting
"The Valley heat was making the house impossible by late afternoon. Copperline found a return-air restriction, corrected the filter cabinet issue and gave us numbers we could use to compare future equipment quotes."
