Performed a thorough HVAC system inspection today. Observed a 23° temperature split between 79° return and 56° supply air, indicating good performance. Blower wheel slightly dirty. No condensate safety switch present. Evaporator coil clean, while condenser coil requires cleaning. All capacitors, including compressor run, blower run, and condenser fan run, tested within tolerance ranges. Recommend scheduling a coil cleaning service to optimize system operation. No other deficiencies noted.
