Was informed unit wasn’t keeping up. The unit utilizes R 22 refrigerant. Check capacitor was still in range. Amp drive compressor 5.8 fan motor was .8 A check refrigerant charge. 68/179 sh6. Sc7. Temperature difference was 18°. Can find any reason why the unit wouldn’t come on yesterday when there was a call for cooling as there’s no float switches in the crawlspace on the equipment.
