Tech Cody arrived to Customer's home and met Mrs. Ristau. She guided me inside to the thermostat and attic access, I started the tune up at the indoor unit. I found the coil to be clean with no signs of corrosion, the blower wheel was clean along with the entire cabinet. Outside I started with washing the coil before taking any readings. The electrical readings showed the equipment to be operating normally according to manufacturer data tag. There was no compressor saver installed and I explained the importance of this component to the homeowner. She did not want to purchase a membership or compressor saver with us without first talking to he husband.
