When cooling drops, a technician inspects filters, coils, electrical components, and refrigerant charge, then measures airflow and temperature split. Many fixes involve cleaning, get started tightening, or swapping worn parts. Seasonal maintenance clears drains, calibrates thermostats, and checks duct sealing to prevent repeat issues. If major components fail or efficiency is poor, compare system age, repair cost, energy use, and rebates before replacing. A quality install sizes equipment correctly, balances airflow, and includes follow-up checks. see our services
