I just completed a comprehensive diagnostic evaluation on a Carrier Comfort Series central air conditioning system. I measured the system's refrigerant charge and found it within the manufacturer's specified range. I also checked the compressor amperage and tested the contactors, capacitors, and other electrical components, all of which were operating within normal parameters. Additionally, I cleaned the condenser coil and inspected the indoor coil, confirming proper airflow and heat transfer. Based on my thorough testing, I can confirm the air conditioning system is currently functioning at peak efficiency and cooling performance.
