Responded to no cooling complaint on commercial rooftop unit. Previous breaker issue had been addressed, but unit still not cooling properly. Upon arrival, accessed rooftop unit and removed side panel to inspect internal components. Connected manifold gauges to measure refrigerant pressures and temperatures. Initial diagnostic readings showed suction pressure at 58.2 psig with 63.6°F temperature, resulting in 31.2°F superheat on R-22 system. Liquid line pressure measured 183.7 psig at 80.7°F with 15.0°F subcooling. System analysis indicated abnormal operating conditions preventing adequate cooling performance. Documented beginning temperatures and pressures for diagnostic purposes.

Completed preventive maintenance clean and check on two air conditioning systems per comfort plan agreement. Both units were found to be one pound low on refrigerant and were recharged to manufacturer specifications. Documented low refrigerant charge for monitoring during next spring's maintenance visit, with recommendation to schedule service in June or when ambient temperatures exceed 65 degrees to allow proper system assessment. Advised that if refrigerant loss reoccurs, further leak detection and system evaluation will be necessary to determine viability of repair versus replacement. Customer reported noise concerns with recently installed furnace but later determined likely cause to be birds in vicinity rather than mechanical issue. Customer requested thermostat switch replacement; advised that scope of work is limited to simple switch replacement and any additional electrical modifications would require licensed electrician. Photographed both thermostat units showing operational
