# HVAC Service - No Cool U10 Responded to no cooling complaint on single outdoor condensing unit. Upon arrival, performed comprehensive system diagnostics using digital manifold gauges to measure refrigerant pressures and temperatures across the system. Suction pressure reading of 139.7 PSI and liquid line pressure of 300.4 PSI were recorded, along with temperature differentials showing 48.8°F suction temperature and superheat reading of 27.1°F. System evaluation revealed abnormal operating parameters indicating potential refrigerant charge issues or airflow restrictions. Utilized Fieldpiece digital instruments to verify superheat and subcooling calculations, confirming system was not operating within manufacturer specifications. Additional measurements showed discharge air temperature of 75.9°F and return air temperature of 92.4°F, with a temperature split of only 3.6°F, well below the expected 15-20°F differential for proper cooling operation. Conducted thorough inspection of atti

Responded to no-cool service call on 2017 Lennox air conditioning system. Upon arrival, obtained homeowner permission before proceeding with diagnostics. Inspection revealed extremely dirty and clogged air filter causing restricted airflow to the system. Filter showed heavy accumulation of dust, dirt, and debris with significant discoloration throughout. Top screen and mesh components also found obstructed with debris. Removed and replaced severely soiled filter. Cleaned debris from unit exterior and surrounding area where vegetation and organic matter had accumulated near equipment. Verified proper airflow restoration after filter replacement. System returned to normal cooling operation with improved air circulation and accurate temperature readings.
