Seven-year-old propane furnace and condenser. The outdoor ambient temp was approximately 67 degrees and the indoor dry bulb was 72. Checked the air filter and it didn't need to be replaced. The cool supply air was 46 degrees and the room temperature return air was 67 degrees for a Delta T of 21. Measured 5.5 Amperes and 120 Volts on the air circulation system and its voltage enhancer had a correct uF charge. Verified the circuit board and wiring were in good condition, the indoor coil wasn't dirty, and no leak was detected. Purged the condensation pipe and the condensation pump's discharge tube with CO2 (and added some descaler) to prevent clogs. The refrigerant pumping system's run amps were 5.6 (RLA is 15), the start amps were 4.9, and the air exhaust system's amps were .65 (FLA is 1.1). Cleaned the electrical compartment, and verified the blades, disconnect, wiring, and voltage distributor were in good condition. The latter had a normal 240 Volts across it.
