The evaporator coils were cleaned using NuCalgon Evap-Fresh No-Rinse condenser cleaner. After adjusting the temperature controller, the freezer is maintaining optimal temperature range.

Earlier this month, in Boston, MA, during an annual tune-up and maintenance session for a commercial client's HVAC system, I discovered a significant airflow blockage in a Carrier Infinity system. The blockage was caused by a heavily soiled filter and accumulation within the ducts. I replaced the old filter with a new HEPA filter and performed a thorough cleaning of the ducts. Additionally, I recalibrated the system's Honeywell programmable thermostat to ensure efficient operation. Post-maintenance testing confirmed the system is now running efficiently, with improved air quality and circulation.

This morning in Boston, MA, annual maintenance call for customer. I thoroughly inspected an HVAC system and here are my findings: The return air temperature was 73°F and the supply air was 53°F, resulting in a good 20° temperature split. The total external static pressure was 0.7 WC, with the return at 0.4 WC and supply at 0.3 WC - I recommend checking and replacing the air filter. The blower wheel, evaporator coil, blower run capacitor, and all gas safety controls were clean and functioning properly. The flame sensor was cleaned during the inspection. Both the condenser fan and compressor run capacitors tested within normal tolerance ranges. I have no other additional notes, as overall the HVAC system is in good operating condition without any major issues present.
