Preformed cooling maintenance on single system. I tested all electrical components on the inside unit. All tested within manufacturer specifications. I treated drain line with tots c. Filter did not need to be changed at this time. Temperature being supplied to the home is at 51 degrees and air being returned to the unit was at 71 degrees. I did notice the blower wheel to have dust/debris build up. I proceeded to the outside unit where I tested all electrical components on the outside unit along wi5 run and start amps of the compressor and fan motors. All tested within manufacturer specifications. Although I did find that the capacitor was testing closer to the lower end of the manufacturer range it is rated for 45/5 and was reading 43.7/45 and 4.9/5. The Contactor was testing on the higher side of its range at 19.2 ohms. Also the compressor is starting on the higher side of its range as well at 50/77. I left estimates for a compressor saver bundle along with a blower wheel cleaning. U
